One-humped camels (Camelus dromedarius) are important source of meat, milk and leather production for humans in southern Algeria. Camel livestock farming is confronted with several obstacles, including abortive diseases which can be transmitted mainly by ticks. The study was carried out in Ouargla region, South Algeria, between January and December 2017. The objective of this study was to identify ticks in camels and to study the relationship between camel abortion rate and the presence of different species of ticks. A total of 350 camels (including 171 males and 179 females) was used in this study. Ticks were searched on the entire camel body (head, neck, hump, abdomen, forelegs, back legs, and tail area). Results showed that 215/350 (61.4%) camels were infested by ticks including 137/171 (80.1%) and 78/179 (43.6%) males and females, respectively. A total of 46/179 (25.7%) camel females had aborted and all these were revealed infested by ticks. A total of 298 ticks was collected including the following species Hyalomma dromedarii (90.9%), Hyalomma impeltatum (5.37%) and for the first time in Algeria, Amblyomma variegatum (2.35%) and Rhipicephalus turanicus (1.34%). H. dromedarii was the most frequent (p<0.001). The study showed that the dromedary was highly infested by ticks. The presence of ticks in all aborted female camels certainly indicates their important role in one-humped camel abortions in Algeria. The identification of tick-borne abortive agents in camels is important in order to establish an effective abortion control plan.

Congenital or acquired abnormalities in genital tracts of ewes leading to sterility, which cannot easily to be identify by routine clinical examination. Reproductive tracts abnormalities regarded as a major causes lead to loss of sheep production. This study aimed to examine reproductive tracts in slaughtered ewes grossly and microscopically. This study was conducted on 270 genital tracts of non-pregnant ewes at Khanky slaughterhouse in Duhok province. Samples were collected within the period from September 2019 to March 2020. The results showed that 24.1% exhibited acquired abnormalities and 75.9% were exhibited normal. The rate of uterine abnormalities was about 3.3%, ovarian abnormalities comprised 17.8% and oviduct abnormalities were 3.0%. The most common pathological conditions of the uterus were endometritis at rate 2.2%, hydrometra (pseudopregnancy) and mummifies foetus at rate 0.4% and 0.4%, respectively. In the ovary, the common abnormalities were ovarobusral adhesion 14.4%, ovarian cysts 1.1% and Para ovarian cysts 0.4%. The abnormalities of the oviduct were uterine tubes obstruction 2.6%, followed by hydrosalpinx 0.7%. It is concluded that pathological lesions, such as endometritis, ovarian cysts and hydrosalpinx in ewes could result in infertility or sterility of the ewes leading to economic losses to farmers.

This study was conducted to determine the genetic variation of the prolactin (PRL) gene in 5' flanking region and its role with several reproductive traits in Awassi sheep. One-hundred six Iraqi sexually mature and healthy Awassi ewes that aged between 2 and 2.5 years were included in this study. Ewes were classified into two the main divisions: ewes producing twins and ewes producing single offspring. Two genotypes (AA and AT) were observed in Awassi sheep. While genotype AA was detected in Awassi ewes that produced twins, genotype AT was detected in ewes that produced a single offspring. The sequencing reactions identified nine SNPs in the prolactin gene at the 5′ flanking region in Awassi sheep, differing from the prolactin reference sequence (GenBank accession number X16641.1). Genotype AT possessed one single nucleotide polymorphism SNP substitute comparison with the AA genotype in Awassi ewes. The association analysis revealed that the AA genotype is characterized by significantly higher levels of the progesterone concentration, twinning ratio, fecundity, and prolificacy than the AT genotype. In conclusion, a new SNP (g.1209 A>T) was discovered within the ovine flanking region which potentially influences prolactin gene expression. These results showed that the genotype AA associated with high prolificacy of Awassi sheep may be used as a selection criterion for improving the reproductive performance of Iraqi Awassi sheep.

The current study conducted to investigate the anatomical and histological structure of the cornea in sparrow hawk accipiter nisus. By using an optical microscope and histological stains. Anatomical results showed that the cornea composed of two parts, the peripheral cornea and the central cornea, and there was variation in corneal thickness according to the anatomical region. Histologically, the cornea consists of five layers. The first layer of the central cornea consists of non- keratinized stratified squamous epithelial tissue composed of four rows of cells. Whereas, Bowman's membrane appeared clear and thicker on the dorsal side than on the ventral side. The corneal stroma consists of collagen fibers arranged in three secondary layers within the stroma. The corneal stroma also distinguished by the presence of fibroblast cells, which randomly distributed among the collagen fibers. The Descemet membrane appeared clear and equal in thickness between the dorsal and ventral sides. The endothelium tissue appears in the form simple squamous epithelia. The histological structure of the cornea root seemed similar to its formation in the central cornea. Still, it characterized by the presence of pigment cells spread in the stromal corneal root. Among the distinct results that appeared in this study is the presence of blood vessels spreading in the root of the cornea. The study concluded that the anatomical and histological structure of the cornea in this bird distinguished by some specialties that contribute to increasing the effectiveness of the function of the cornea in this bird.

Lambda-cyhalothrin (LCT) is a type II pyrethroid insecticide, which is widely used to control a large variety of agricultural pests throughout the world as well as in Algeria. The aim of this study was to investigate the effects of LCT exposure on body weight, hematological and blood biochemical parameters and to evaluate histopathological changes in some organs. Twelve (12) healthy local rabbits with a mean body weight of 1.8 kg were divided into three groups of four each: First group was kept as control (CTRL), second group (LCT 10) and third group (LCT 20) were given oral LCT at 10 and 20 mg/kg b.w, respectively three times a week for 25 days. The results showed no significant difference in mean body weight between groups. Blood analysis revealed no significant variation in hemogram between LCT-treated groups and control group. Serum biochemical analysis revealed a significant increase (P˂0.05) in total cholesterol content and glucose in LCT10 and LCT20, respectively. Total protein increased significantly (P˂0.0001) in LCT 20 group. While a very high increase (P˂0.0001) in the activity of asparatate aminotranferase (AST) was recorded in both treated groups, no change was observed in the activity of alanine aminotransferase (ALT). LCT treatment exhibited severe histopathological changes in liver, kidney, lung and brain. It is concluded from the study that LCT produced serious toxic pathological alterations and metabolic dysfunctions in rabbits.

The current work aimed to study the normal values of some hematological and biochemical criteria of local quail and the effect of the breed, sex, and age on them. Two hundred quail (100 birds belong to each of white and light brown feathers local breeds), they were randomly distributed at 1st-day-age into 5 replicates, 20 birds/ replicate for each breed, and the study continued till the age 84 days. The results of the current study had revealed that the breed and the age, each alone did not significantly affect the physiological and biochemical parameters in this study, whereas the sex factor affects significantly most of the study parameters. The males were highly significant as compared to the females in the following parameter values: red blood cells count, hemoglobin concentration, packed cell volume, mean corpuscular hemoglobin concentration, monocytes%, basophils%, glucose, cholesterol, uric acid concentrations and aspartate aminotransferase activity. While the females were significantly higher to the males in mean corpuscular volume, lymphocytes%, triglycerides, total protein, globulin, and alanine aminotransferase activity. In conclusion, the sex of the bird alone and its interaction with breed and age had the greatest impact on the hematological traits.

The aim of this study was to evaluate the intensity of decorin in normal and the injured equine cadaver limbs. The study was carried out using superficial digital flexor tendon (SDFT) samples harvested from equine cadaver limbs. Randomly assigned left or right equine distal forelimbs were collected in normal (7 - 14 years old ± 2.86 SD) and injured (6 - 16 years old ± 3.64 SD) SDFT. Small pieces of approximately 5 x 5 x 3 mm were collected from normal and the injured areas at the mid-most metacarpal regions and fixed in 4% paraformaldehyde at room temperature. They were routinely prepared for H&E staining in order to confirm whether they were normal or injured. Then they were prepared for immunological assay, the primary and the secondary antibodies were prepared in a standard ratio. The results showed that the distribution of decorin was varied between fascicles and the interfascicular matrix (IFM), and the latter showed greater intensity than the fascicles. The injured tendons showed up-regulation of decorin, it was intensively expressed in all the cases of injured tendon, particularly fascicles showed significant up-regulation when compared to the normal tendon. It was concluded that decorin was varied regionally, and the injured tendons presented a significant up-regulation.

Shepherd dogs have been implemented in the transmission and distribution of many threatening pathogens. The presence of extended-spectrum-cephalosporin resistant Escherichia coli (ESCR E. coli) in dog feces can constitute a significance risk to human health due to transmission of antibiotics resistance from dogs to humans, other animals and the surrounding environment. Therefore, in this study, phenotypic and molecular characterization of fecal ESCR E. coli were investigated in shepherd dogs accompanied sheepherders in urban areas. Sixty-seven fresh fecal samples were collected from shepherd dogs from different regions of Mosul city. Bacteriological examination of ESCR E. coli was done using MacConkey agar with cefotaxime followed by subsequent PCR confirmation of the CTX-M gene using specific primers and molecular characterization using specific primers directed to CTX-M-1, 2 and 9 groups. The results of bacterial examination showed successful confirmation of ESCR E. coli which has been isolated from fecal samples of shepherd dogs 58.2% (39/67). In addition, detection of CTX-M gene was confirmed in 53.7% (36/67) of E. coli isolates. Furthermore, molecular characterization of CTX-M gene revealed the presence of only one genotype belongs to CTX-M-1. However, both of CTX-M-2 and CTX-M-9 genotypes were not detected in this study. This study concluded that shepherd dogs have an essential role in carrying and spreading of ESCR E. coli especially in urban regions.

This study aimed to know the comparative histological structure and histochemistry of the Ileum in two birds that are the Turkey (Meleagris gallopavo) and the Cockatiel (Nymphicus hollandicus) using histological stains and histochemical techniques. The results showed that the Ileum wall in the two birds is composed of the histological layers that make up the rest of the gut wall, with many differences between them. The villi appeared in Turkey in various shapes, longer and more numerous than in the Cockatiel. The villi lined with a simple epithelial tissue in the two birds, containing the goblet cells. Lieberkuhkn''s crypts under the villi appeared in the two birds and had spherical secretory, and some secretory units contained the enteroendocrine cells. The Muscularis Externa appeared distinctively in Turkey than in the Cockatiel, and it was of three sublayers while in the Cockatiel from two sublayers. Histochemical results showed medium to a strong positive response to the epithelial tissue to AB pH 1, AB pH 2.5, PAS techniques while a weak positive in the intestinal glands to these techniques, with varying degrees between the two birds. While the response was positive for BP technique in the epithelial tissue and negative in the glands, as well as the same response appeared for the SB technique. The current study concluded that the Ileum structure in the two birds is identical with histological and histochemical differences that are appropriate to the nature of each bird''s food.

Staphylococcus (S.) aureus is deemed as one of the main pathogens in human and animals. S. aureus can produce various toxins that usually implicated in food poisoning. S. aureus could possess the mecA gene, which is the principle cause of β-lactam antibiotics resistance, particularly methicillin-resistant S. aureus (MRSA). Broiler’s meat is worthy food for humans, but it may expose to contamination with MRSA during the poultry processes in the slaughterhouse. The current study aimed to assessment the spread of S. aureus and MRSA in the broiler carcasses via detection the nuc and mecA gene and their resistance to different antibiotics. Fifty skin swabs were taken from the broilers carcasses, during their processing in poultry slaughterhouses that scattered in various districts in the Nineveh Governorate during the period between January to April 2020. The results showed that S. aureus was recovered in broiler’s skin swabs at a percentage of 66% (33/50) which confirmed by nuc gene, while MRSA isolates constitute 40% (20/50) of all S. aureus isolates, and distinguished as MRSA by their possessing mecA gene. All MRSA isolates were resistant to Ampicillin/Sulbactam, Methicillin, and Ampicillin/Cloxacillin antibiotics. The present study stressed on the reduction as much as any possible source of broiler carcasses contamination with S. aureus including MRSA during and post poultry processing, through applying high levels of hygienic conditions in all poultry processing premises to attain high standards of sustainability and public health standards.

Little works of literature studied the anesthetic effect of ketamine in different ages of broiler chickens, hence this study intended to examine these alterations in chickens at different ages. The doses of ketamine that causes hypnosis in 50% of the chickens (hypnotic ED50) were 7.90, 7.90 and 6.80 mg/kg, intramuscular (IM) at 10, 20 and 40-day-old chickens, respectively, whereas the doses that resulted in analgesia in 50% of the chickens (analgesic ED50) were 12.92, 12.92 and 6.50 mg/kg, IM. The onset, duration and recovery from ketamine hypnosis were in an age-dependent manner and significantly longer at 40-day-old, although the depth and sensitivity of chickens to ketamine hypnosis rises as the age advancing forward. Ketamine analgesia is more effective at 40-day-old. There are neurobehavioral deficits, according to the age of chickens when injecting ketamine in a subtle dose of 1 mg/kg, IM. The concentrations related to alanine transaminase (ALT) and aspartate transaminase (AST), tested in the serum, reveal that the 40-day-old chicken group differs significantly from 10 and 20-day-old chicken’s groups which all treated with single ketamine dose (25 mg/kg, IM). In conclusion, the present work discovered that ketamine’s efficacy, including hypnosis, analgesia and neurobehavioral activity will be increased as the age is progressing, suggesting that the veterinarians need to take it into account when preparing the dose regimen of ketamine anesthesia for different ages of animals.

Sheep and goats represent an essential source of meat, milk and wool production. Infectious viral diseases of small ruminants hinder the expected benefits from these animals. The aim of the present review was to shed light on diagnostic procedures and monitoring of some important infectious viral diseases that affect small ruminants. Border disease (BDV) is caused by Pestiviruses. The affected herds are usually expressed high rates of infertility and production of underweighted-lambs. Affected lambs usually die within days after lambing. A commercial killed whole virus vaccine was produced for BDV. Louping ill (LI) is caused by the Louping ill virus, which is transmitted by Ixods ricinus ticks. The LI virus typically causes fever, anorexia and encephalomyelitis. Death could occur 1-3 days after the beginning of signs. The available Louping ill vaccine is composed of inactivated killed virus. Nairobi sheep disease (NSD) is a tick-born infectious disease caused by Rhipicephalus appendiculatus ticks, characterized clinically by fever, abortion hemorrhagic gastroenteritis and high mortality. Inactivated killed oil adjuvant virus vaccines are available for the control of Nairobi sheep disease. Akabane disease (AKAV) is a Culicoides borne viral disease belongs to orthobunyavirus that has a teratogenic effect on the fetus of cattle and small ruminants. A live attenuated virus vaccine and inactivated virus are commonly used. This review concluded that the modern diagnostic tools are urgently needed not only for diagnosis but also for monitoring viral disease control and control programs.

This study aimed to induce estrus by using Human Menopausal Gonadotrophin (HMG) in Iraqi Awassi Ewes and comparison its action with Pregnant Mare Serum Gonadotrophin (PMSG). The study was carried out between first of June 2018(non or earlier-breeding season) until all ewes lambing in the middle of November 2018. Sixty Iraqi Awassi ewes aged 2-4 years old and weight 35-45 kg were used in this study. Ewes were divided randomly into three groups, (20 ewes per each). All ewes comprised of intra-vaginal sponge impregnated by progesterone for 12 days. Control ewes (C) were injected intramuscularly with 2ml of sterile saline solution, HMG treatment group (HMG) were injected intramuscularly with 300 IU of HMG hormone while PMSG treatment Group (PMSG) were injected intramuscularly with 500 IU of PMSG at the same day of sponge removal. Estrus response percentages were 40% (8/20), 85% (17/20), 90% (18/20) in control (which significantly change P<0.05), HMG and PMSG groups, respectively. Estrus onset time was 71±1.9, 72±1.9, and 71±1.0 hours, respectively, also the data records no significant changes in estrus duration means which were 31±0.5, 31±0.7 and 31.0±0.5 hours, respectively in all groups. The pregnancy rate was 30% (6/20), 85% (17/20), 90% (18/20), respectively (control group significantly change P<0.05). The gestational period was 155± 1.4, 155±.1.3 and 155± 1.6 days respectively in all the groups and the twining rate were 1.1±0.3, 1.1±0.1 in both HMG and PMSG groups respectively without significant changes (P<0.05) while control group record no twining data. The result of this study recorded rise of dystocia and pregnancy toxemia which were higher in the PMSG group when compare with other groups. We can conclude that using HMG and PMSG hormones show a high rate of successful when they used in estrus synchronization programs but the birth problems need more investigation.

Aspirin are commonly used analgesic, anti-inflammatory, and anti-pyretic drug in medicine, oral route is the most common one for drug administration as a result it will produce different adverse effects like peptic ulcer, nephropathy, and thrombocytopenia even with low and continuous therapeutic dose, so the alternative topical route is preferable with minimal adverse effects and effective concentration.Therefore, in the present study was to investigate whether the antinociceptive property of aspirin would enhance if used aspirin as nanoparticles after preparing it in several forms (gel, cream and ointment). Thirty-two healthy male mice weighing 30-35 gm. were used in the present study. The animals were divided as a randomized design. Each mouse was treated topically. All drug concentration of aspirin was prepared using gel, cream and ointment as vehicle and topically application on fore and hind paw of experimental animals. Pain was induced by application of hot plate for assessment of latency of pain stimulus. Time from placement to jumping or hind paw licking was recorded as latency of response. The result showed that the median effective concentration (EC50) for analgesic effect of aspirin (gel, cream, and ointment) were 0.848, 0.958 and 1.00% respectively while these EC50s were decrease when used nanoparticles aspirin (gel, cream and ointment) to 0.72, 0.657, and 0.701% respectively. In conclusion, topical applied of aspirin will produce effective therapeutic antinociceptive effects in mice although gel preparation produce a better response followed by cream, then ointment due to pharmacokinetic properties. Also nanoparticle preparation will produce superior response in all forms, whether Nano aspirin is prepared in gel form, cream or ointment.

This analysis aimed to (i) report diseases of animals received at the Veterinary Teaching Hospital, University of Mosul between years 2017 and 2019, and (ii) examine whether its records can be used in studying the factors associated with different diseases. In this analysis, medical records of 1,280 cases examined and diagnosed at the internal medicine section and/or clinical pathology laboratory were used. Odds of diseases as a function of different factors were modeled using conditional logistic regression. Results revealed that the number of cases was increased in 2018-2019 compared to the previous academic year. The minimum number of cases was received in autumn, and the maximum was in summer. The most received cases were from areas located at the south inside Mosul city. The most received cases were generally gastrointestinal disturbances, blood parasites, and respiratory infections. Skin affections were also frequently received. Modeling diseases in ruminants indicated that blood parasites infection were higher in old ages compared to younger, greater in spring, summer, and autumn compared to winter, and more in city countryside compared to its inside. Gastrointestinal parasites infection was greater in old ages compared to younger, higher in summer compared to autumn, winter, and spring. Respiratory infections were higher in young animals compared to older ages, and greater in summer compared to autumn and spring. Enteritis of different causes was higher in young animals compared to older ages, and greater in winter compared to summer. In conclusion, records of this hospital are useful for studying animal diseases.

Although antibiotics are valuable drugs for treatment of bacterial and some parasitic infections, their presence in animal products have a potential public health hazard. This study investigated antibiotic residues in goat raw milk and thermal effect on residues. Samples were collected randomly from different farms and retail outlets in Erbil city from January 1st to June 30th 2019. The residues were detected by disc diffusion assay against Bacillus subtilis bacteria on Muller Hinton agar. The occurrence rates among milk samples was 14.9%, also these residues in the samples was 13.5% and 16.4% in farm samples and retail store samples, respectively. No significant differences were found between sampling sites (farms vs sale points). Regarding the seasonal variations, spring was found to be associated with gradual decrease in antibiotic residues frequency in milk. Boiling for 5 minutes was the most effective treatment (among pasteurization and microwave heating) that inactivated antibiotic residues in 57.7% of positive samples. Such occurrence rate of residues is alarming and require authorities to observe and validate the quality of raw milk introduced to markets for consumers. Further evaluation of antibiotic stability period in raw milk is highly recommended.

Low-level laser therapy (LLLT) was applied to alleviate pain with minimal adverse effects. This study was conducted to evaluate the analgesic effects of low-level laser therapy for pain control to help in surgical and emergency cases. The present study has demonstrated these effects experimentally on forty-five male albino mice weighing 45±5 grams. Creation of pain in animals was done by injection of 50µl of 5% formalin into the left posterior paw. Lifting of the paw was considered as an indicator of the pain. All animals were divided into 3 groups 15 mice in each group. In group A the LLLT 820nm.200mw, 48J/cm2 was focused on the affected paw for 1 min. In group B a diode laser with same dose in group A and different time used to irradiate the injected paw continuously for 30 seconds. The group C (control group); the laser probe was placed over the affected paw for concurrent but the apparatus was switched off. The results demonstrated that there were significant differences between group A and B when compared with group C during the 5 minutes as well as in 10 minutes and 15 minutes. Group A also registered a superior analgesic effect when compared with group B. Groups of LLLT were better than those found for control one and the irradiation continuous for one minute was better than 30 seconds at 5,10 and 15 minutes after the creation of pain.

Sheep possess desirable characteristics for farmers such as resistance to disease, good acclimation to environmental fluctuations, and endurance to extreme weather. This may, in part, be due to hematology characteristics and various types of hemoglobin that interact differently to external changes; displaying various reproductive ability in certain environmental conditions. This review aims to investigate the effect of hematology parameters and hemoglobin types on the adaptation and reproductive performance of sheep. Hematological parameters are useful tools for the detection of adaptation and physiological traits of these animals. The reproduction of sheep has depended on the ability of each type and breed to acclimate to different environmental conditions. In addition, hemoglobin types have also been correlated with the environmental adaptability and physiological traits of sheep. Thus, the present review provides useful information on the association of hematology parameters and hemoglobin types in sheep with adaptation and reproductive performance, and could be used as vital tools that help in determining the species or breed of sheep that are more adapted to certain environments or have more reproductive potential.

Foot-and-mouth disease (FMD) is an extremely contagious viral disease affects all cloven- hoofed animals. The present study aimed to investigate the epidemiological situation of FMD in Egypt during 2017 and 2018, based on antigenic and genetic characterizations of FMD virus (FMDV). Thirty oral epithelia were collected from vaccinated animals (14 native cattle and 16 water buffaloes) showed clinical signs of FMD in four Egyptian governorates having outbreaks. In all collected samples the antigen detection was performed using enzyme-linked immunosorbent assay (ELISA), while the genetic characterization was done by using conventional reverse transcription polymerase chain reaction (RT-PCR), Sequencing and phylogenetic analysis were constructed for genetic characterization. The obtained results of FMDV antigen detection ELISA indicated that 50% of the examined samples were positive for FMDV and serotyped as serotype O 40%, serotype SAT2 33% and serotype A 27% respectively. RT-PCR confirmed the results of FMDV antigen detection by ELISA. Six amplicons were sequenced and phylogenetically analyzed for viral protein 1 (VP1) of FMD. Results demonstrated that genotype O was related to East Africa-3 (EA-3) topotype with 12.7% difference from vaccine strain O-IRN-8-2005-Pan-Asia-2. Furthermore, genotype A clustered into Asia topotype with 6% difference from vaccine strain A-IRN-1-2005. Meanwhile genotype SAT2 in 2018 was related to VII topotype but it was in close relation with strains isolated from Libya in 2012 with 94.3% amino acid identity that differ from the previously circulated SAT2 since 2012 and recorded recently in Egypt. The presented results confirmed the circulation of a new topotype of serotype SAT2.

Abdominal adhesion is one of the main and important post-surgical problems and, according to available literature, the probability of their occurrence after surgery is higher than 50%. The present study intended to estimate the effect of Nano n-acetylcysteine on macroscopic and microscopic features post-surgical adhesions in an animal model. Twenty-five adult male Wistar rats, 200-220 gr, were randomly divided into five equal groups and underwent intramuscular anesthesia by injection of ketamine 10% at 50 mg/kg and injection of xylazine 2% at 5 mg/ kg. The treatments included three Nano-NAC groups at different dosages 50, 75 and 150 mg/kg, an NAC group, and a control group. On days 14 and 28 post-surgery, the abdomens of all rats were re-opened for macroscopic and microscopic evaluation of adhesions. Based on the results of macroscopic evaluation, the group receiving Nano-NAC 50 mg/kg had the lowest and the control group the highest mean adhesion scores on days14 and 28 post-operations. Histopathological evaluation also revealed that the group treated with Nano-NAC 50 mg/kg had the lowest level of inflammation and fibrosis score among the five groups on days 14 and 28 post-operation. Considering the results obtained in our experimental model and the increasing use of nanotechnology in the manufacture of biomedical drugs, it seems that use of Nano-NAC at low doses 50 and 75mg/kg after laparotomy can significantly reduce adhesions.

The animal was carried alive from the Al-Fthilya region in the eastern north of Mosul and expired before hospitalization. Statement of the owner prevailed sudden deaths of healthy animals or a concise course of illness followed by respiratory distress and nervous manifestations and death at 14 mature animals within mortality rate reached 15.5% in the herd. Necropsy findings and histopathological analysis showed that encephalitis included hyperemic cortical blood vessels, severe perineuronal edema, microglial proliferation. The lungs revealed severe pulmonary edema and signs of peracute pneumonia. Liver sections demonstrated congested portal and central veins and lobular sinusoids with centrilobular coagulative degeneration. At the kidneys, we detected both glomerular and interstitial nephritis with severe tubular cell necrosis. We concluded a state of bacterial septic shock, suggesting Pasteurellosis as a probable etiologic factor from the symptoms and pathological examination. The case was reported, and laboratory tests were requested.

The objective designated to discover the analgesic effect of nefopam in the normal (non-stressed) chickens and its possible alteration due to hydrogen peroxide (H2O2)-induced oxidative stress (OS) in 7-14 day old chickens. The analgesia of nefopam has been increased by 47% in the stressed chickens by measuring the analgesic Median Effective Dose (ED50) value. This value was 9.10 mg/kg, IM in the normal chickens where it became 4.80 mg/kg, IM in stressed chickens. There is a significant rise in the antinociceptive action of nefopam 18 mg/kg, IM by 88% in the stressed group of chickens in comparison with the normal one elicited by an electro-stimulation and formaldehyde 0.05 ml of 0.1% tests for induction of nociception. The observations showed several significant stimulatory modifications in the neurobehaviour when nefopam treated with a subtle dosage 1 mg/kg, IM in the stressed chickens concerning the latency to move, squares crossed and time of the tonic immobility response test. Significant damage was detected in the liver function when nefopam injected at 18 mg/kg, IM in stress chickens in comparison to normal one by 28, 33 and 65% as estimated through Alkaline phosphatase (ALP), Aspartate trans-aminase (AST) and Alanine trans-aminase (ALT) concentrations in the serum, respectively. The sum of data findings indicated that H2O2-inducedOS increased the analgesic activity of nefopam in the chickens; despite the changes occur on the neurobehaviour and liver function. The dose of nefopam should be reduced when preparing the therapeutic regimen in the stressed animals.

The study aimed to investigate the analgesic as well as anti-inflammatory effects of diclofenac and silymarin in chicks. The up and down procedure was used to assess the effective median analgesic dosages (ED50s) of diclofenac and silymarin administered intraperitoneally either alone or at the same time in chicks. Also, Analgesic and anti-inflammatory effects were measured by using the formalin test. Isobolographically, ED50s of drugs were assessed for the manner of interaction between both. Formalin testing also supervised analgesic and anti-inflammatory coadministration impact of diclofenac and silymarin at doses 5 and 40 mg/kg and 2.5 and 20 mg/kg respectively.Analgesic ED50s for diclofenac and silymarin in chicks were 10.74 and 83.4 mg/kg separately. Concomitant administration of drugs at a fixed ratio 0.5:0.5 and 0.25:0.25 of their individual ED50 values reduced their ED50s to 2.10:16.81 mg/kg and 3.90:23.50 mg/kg separately. ED50s isobolographic analysis showed synergistic analgesic effects of both drugs. Additionally, coadministration of both drugs had effective analgesic and anti-inflammatory effect, as seen by formalin test, led to a significant rise in latency to lift right foot beside a significant decline in foot lifting frequency when compared with control value, the anti-inflammatory reaction was demonstrated by a significant decrease in foot thickness compared to control value.In conclusion, the data indicate that diclofenac and silymarin coadministration controls acute pain synergistically, and suppress inflammatory reaction.

This work was aimed to explore the details of the ion channels gating and there physiological role in sperm in the future.Mouse spermatozoa express a pH-dependent K+ current (KSper) thought to induce hyperpolarization to enhance Ca2+ influx via alkaline-activated calcium channel (Catsper) to initial a so-called sperm capacitation by NH4Cl during travelling in female genital tract for fertilization. However, the regulating mechanism of the Ksper and Catsper channels by membrane potential and pHi remains uncertain, because the complexities of two channel kinetics in sperms is hardly to be overcame at this stage. Here we show that difference of the intracellular [Ca2+]i between the wild type (Wt) and knockout (KO) Ksper (or Slo3/) mice in the application of the Slo3 blockers, Guinidine (QD) and Clofilium, and NH4Cl, indicating that Ksper channels, encoding Slo3 gene, dominates the membrane potential of mouse sperms to increase the intracellular [Ca2+]i and [pH]i during the capacitation process to play a vital role in fertility. Furthermore, a HH model sperm built directly with the native Ksper and Catsper currents in sperms reveals two functions of membrane potential and intracellular pHi, allowing us to calculate the intracellular pHi by NH4Cl, based on membrane potentials recording from current-clamp experiments. During modeling, we found a caton channel with Vrev= +20 mV in mouse sperm from the double-KO (i.e. Catsper-/- and Ksper-/-) mice, which is definitely necessary for a model able to match the data.

The Escherichia coli (E. coli) bacteria belong to the Enterobacteriaceae family can cause wide ranges of infections including enteric, extra enteric or opportunistic infection especially in young animals. E. coli outer membrane composed of phospholipid and lipopolysaccharide which reflect the inner and outer layer of the membrane, the main components of lipopolysaccharide LPS are lipid A, core oligosaccharide, and O- antigen. Immunity of LPS was clearly understood in the last 20 years when discovered signaling response in immune cell system, LPS acting as potent activators of immune system especially innate immunity and as a result produce a large variety of the adverse, unfavorable physiological response leading to injury of tissue and endotoxic shock and lastly death.
In this study, we tried to extract and purify the LPS from E.coli local strain and determine the molecular weight, purity, and pyrogenic effect of the product and compare with stander E.coli O55:B5 LPS, the result shows that the hot phenol method with enzymatic treatment give highly pure LPS with high yield reach to 242.4 mg, staining the SDS page gel with Coomassie blue and silver nitrate uncover the high purification of the extracted LPS (ELPS) with no protein contamination, with molecular weight range between 15-23 kDa, HPLC test reveals that purity of ELPS was 100 % compared with standard LPS. The rabbits' pyrogen test confirmed that the biological activity of ELPS. In conclusion, the method of extraction used in this research was valid and give highly pure LPS with enduring substantial pyrogenic activity.

The study consisted of three groups, Control group, hydrogen peroxide group, vitamin C with hydrogen peroxide group, showed that treatment with hydrogen peroxide for mothers led to significant decrease in the weights of young-rats-age21 days and significant increase in the righting reflex test, cliff avoidance and the olfactory discrimination test in young rats at age of week and also in the onset movement test and at the time of negative geotaxis test in-young-rats age21days. Treatment of mothers with hydrogen peroxide caused significant decrease in open-field activity and number of times standing on backlists during 3minutes and in the approach response, touch and sound of young rats at age 21 days. While, hydrogen peroxide treated group resulted in significant increase in time of negative geotaxis test and hydrogen peroxide had no effect on response of tail pinch as compared to other groups. When treating mothers with vitamin C significant increase in weights of youngsters age21days, as well as in onset of movement test and in number of squares cutoff within 3minutes in open-field activity and number of times standing on backlists during 3minutes in young-rats age 21 days. Also there was significant decrease in righting reflex test, olfactory distinction and negative geotaxis test compared to hydrogen peroxide treated group. It was concluded from the study that vitamin C plays an important role as an antioxidant by improving the nervous system function in young rats their mothers exposed to with hydrogen peroxide in drinking water.

This study aims to determine the effects of Tricaine methane‐sulfonate (MS-222) at concentration 150mg/l for one hour as an anesthetic agent to reduce the stress conditions during transfer the fish. Forty fish (Cyprinus carpio) were divide in to four groups: the 1st is control group (fish without both transfer and anesthesia), the 2nd group (fish transfer without anesthesia), the 3rd group (fish anesthesia without transfer) and the 4th group (fish transfer with anesthesia). The induction time reached to 3 minutes while the recovery time take at lasted for 7 to 10 minutes. Furthermore, the cortisol was significantly decreased in fish serum in both anesthetized groups that were transferred or that were left in the pond without transmission in compare to control groups (both transfer and without transfer fish). The glucose level rose significantly (P <0.05) in the serum of fish in both 3rd and 4th groups in compare to control groups. There was no difference in hematological parameters (hemoglobin and packed cell volume), blood sodium ion concentration, and enzyme activity represented by Alanine amino transferase in all groups while level of creatinine phosphate was decrease significantly in both groups 2nd and 3ed in compare to 1st group. It can be concluded that tricaine methane‐sulfonate stimulates the recovery and shortens the time of induction and reduces the stress condition caused by fish transport.

Ear mange is an annoying problem for all animal breeders including rabbit's breeders. This study aimed to compare the efficacy of moxidectin and 10% propolis ointment on rabbits infested with Psoroptes cuniculi with especial reference to some related biochemical parameters diagnostic and prognostic value. For this purpose, a total of thirty-two rabbits: 8 non-infested rabbits (control group (CG) and 24 naturally infested rabbits were used. Infested rabbits were equally divided into three groups: 1st group remained without treatment (diseased group (DG)), 2nd group was treated with moxidectin ((0.2 mg/kg body weight) S/C (MG)). Propolis ointment (10%) was applied topically to rabbits of the 3rd group (PG) once daily. Ear scrapes and blood samples were taken on 0, 7, 14 and 21 days. The ear scraping was examined microscopically and the biochemical parameters were estimated and statistically analyzed. The results cleared that moxidectin achieved the complete healing (14th day) faster than propolis ointment (21st day), but MG suffered from a significant (P<0.05) hypoalbuminemia, increased liver and kidney function tests and cortisol levels when compared to PG. Liver and kidney function tests and cortisol yielded good values of the area under the curve, sensitivity%, specificity%, likelihood ratio, PPV%, NPV%, accuracy rate% in DG, MG (except creatinine) and PG. The study concluded that propolis had a prominent antipsoroptic effect without inducing hepatic or renal toxicity. Liver and kidney function tests and cortisol may be useful markers for rabbit mange diagnosis and prognosis and following up its treatment.

The objective of the current study is to examine the incidence of Lucilia sericata larvae in the sheep in Mosul city, Iraq. From a total of 670 sheep examined, 92 sheep of them 13.7% were infested with Lucilia sericata larvae. For the 516 larvae found in the sheep, 146 (28.3%) was detected to be of the first instars larva, 120 (23.3%) was second in stars larva and 250 (48.4) as third instars larva. As the average number of larvae in the infested animals was 5.6. The infestation percentage in males was higher 26.3% compared to the females 4.2%, where there is no significant difference reported concerning with the age. The prevalence of Lucilia sericata larvae was 8.4% in spring, 38.9 % in summer, 2.4% in autumn and 1.5% in winter. The difference in terms of seasons were statistically significant. Sheep in the rural areas had higher infestation rate in comparison to the sheep in urban area. Most lesions occurred in the breech region, flank, leg and inter digital space of a foot. The percentage of adult flies that merged was 73.3% and the pupariation period was 12 to 20 hours, while the incubation and moulting periods were 7 to 10 days. All flies were similar in the external appearance and belonging to Lucilia sericata causing strike disease in sheep.

Ovine pulmonary adenocarcinoma (OPA) is a cancer disease in sheep caused by Jaagsiekte sheep retrovirus (JSRV). The retrovirus is distinctive among viruses for inducing carcinogenesis of lung epithelial cells and cause a lung adenocarcinoma. OPA has numerous characters same as human lung adenocarcinoma, involving a similar histological organization and motivation of most cell signalling pathways. P53 pathway is frequently changed in human lung adenocarcinoma, in specific due to the increase expression of MDM2 and it is the main regulator of P53. Here, we have a go at something new to confirm the possible expression of p53 and MDM2 in OPA as a translational animal model for human lung adenocarcinoma, and to identify the correlation between P53 and MDM2 expression. 1645 of lung samples from different breeds were macroscopically tested. OPA was recognized in 21 samples and further assessed by histology and immunohistochemistry. Histologically, proliferative cancer foci were distributed and contained of cuboidal or columnar cells and arising papillary to acinar patterns. The nuclear expression of P53 and MDM2 was detected in 90% and 95% respectively in the cancer epithelial cells of OPA respectively. Detectable immunoreactivity for P53 was detected in 6 out of 7 grade I, 7 out of 8 grade II, and 6 out of 6 grade III cancers. In reverse with P53, MDM2 was detected in 18 cases with moderate and high expression. In addition, there was statistically relationship between both protein expressions. Our findings suggested that overexpression of MDM2 plays an essential part in OPA carcinogenesis and is dependable on the grading system, and its overexpression can be convinced by P53 expression.

Omphalocele is a rare type of congenital abdominal wall defect that allows intestines (and sometimes a portion of liver) covered by a paper-thin membrane (amnion) to protrude from the abdominal wall at the navel area. The aim of the current study is to report the first successful rectification of a congenital omphalocele in a day old neonatal cow calf using a basic suture pattern in laparotomy at cattle populous area of Jhang (Punjab). The case was presented at College of Veterinary and Animal Sciences, Jhang. The calf after surgery manifested a steady and progressive growth rate without any complication suggesting the success of the surgical remedy. At the same time this approach is quite economical to the farmer in the context of saving the life of his farm. It is concluded that this surgery can instituted with success in cases with fair body condition, less contaminated in the absence of predominant necrosis of the tissues.

 Sarcosystis spp., has a close relationship with muscles due to its unique localization within skeletal muscle in humans and the animals it infects, as the chronic condition of the disease causes significant economic losses, especially in terms of meat production as a result of the formation of cysts, whether macroscopic or microscopic, in their muscle fibers. Sarcosystis tenella and Sarcosystis arieticanis are the most important pathogenic cysts forming in sheep. In this study, 50 samples of diaphragm muscles of sheep slaughtered in the butchers' shops and the Mosul abattoir were examined grossly, histologically, and using PCR technique as a diagnostic tool to identify or diagnose the causative and responsible species of these changes. The diaphragm samples appeared white and pale on the macroscopic examination, while the tissue lesions were characterized by the presence of Sarcosystis in different numbers and sizes among the muscle fibers, which led to the occurrence of zinker necrosis and intense infiltration of inflammatory cells, especially eosinophil, monocyte, macrophage and giant cells, and also oedema and proliferation of fibroblast. With the formation of fibrous tissue whose intensity was inferred (mild, medium and intense) by using the masson’s trichrome stain. The results of the molecular analysis using the nested PCR technique indicated that these diagnosed microscopic cysts belong to Sarcosystis tenella with a reaction product of 800bp and 500bp.

This study aimed to detect Brucella antibodies in the sera of dairy cows and to identify Brucella species in the milk of seropositive cows. A total of 100 sera and 100 milk samples were collected from two 50-cows groups (group 1 with and group 2 without a history of reproductive problems and/or decreased milk production). Rose Bengal plate test and indirect ELISA were used to explore Brucella antibodies in the serum samples and thereafter milk samples of seropositive cows were undergone PCR analysis using Brucella genus specific primers and 3 pairs of species specific primers for identification of B. abortus, B. melitensis and B. suis. The RBPT showed 22 cows were carriers for the Brucella antibodies, 18 in group 1 and 4 in group 2 whereas the iELISA showed only 10 cows out of these 22 cows were positive, 9 in group 1 and only 1 cow in group 2. The PCR assay, which was performed on milk samples of the RBPT positive cows, revealed 18 samples were positive for the Brucella genus and the Brucella abortus species and were negative for Brucella melitensis and Brucella suis species. As a conclusion, the results of this study showed that brucellosis has been encountered in cows with or without a history of reproductive problems, and the RBPT followed by PCR assay for milk samples of the seropositive cows could provide more specific detection than performing either test alone and could be more useful for rapid screening of brucellosis in dairy cows.

This study was dedicated to detecting the effects of cadmium chloride and of cortisone on experimental infection with Toxoplasma gondii in rats through studying brain tissue. Twenty-four adult albino male rats were used, divided into four groups, comprising: untreated control as group 1, group 2: infected with intraperitoneal injection of Toxoplasma gondii 80 tissue cysts per animal, group 3: infected with Toxoplasma gondii and treated with intraperitoneal injection of cadmium chloride 1.5mg/kg once a week, group 4: infected with Toxoplasma gondii and treated with intramuscular injection of hydrocortisone in a dose 0.5 mg/kg once a week. After 30 days of treatment for all groups, the animals were sacrificed, and the gross and histopathological examinations were performed on the brains of the rats. The results revealed the presence of changes in the infected groups including appearance of toxoplasma tissue cysts in the grey matter, with mild to moderate perineuronal and periaxonal edema. There were further changes observed in infected groups which treated with cadmium chloride including perineuronal satelletosis, perineuronal edema and demyelination in neuronal axons, otherwise the infected groups treated with cortisone did not show any noticeable difference from the group of infection only. It is concluded that cadmium increase the intensity of occurrence of lesions induced by Toxoplasma gondii in the brain tissue of the rats, considering that all noticeable lesions ranged from mild to moderate in severity, and the differences between groups may be related to the nature of the pathogen used.

The current study aimed to determine the pathological effects of chronic poisoning with sodium fluoride on some reproductive organs like ovary, and testis of adult’s male and female albino rats. Thirty-six male and female adult’s albino rats were divided into six groups. The first and second group of male and female rats are control groups was given tap drinking water, the third and fourth groups of male and female rats was given 150 ppm of NaF, the fifth and sixth group of male and female rats was given 300 ppm of NaF respectively for 90 days. The weights of male and female genital were recorded. Histological exam of control groups of female rats showed the typical histological structure of the ovary, while the NaF treated groups showed a decrease in growing follicles, in addition to thickening in tunica albuginea and deposition of eosinophilic material. In male control groups, the sections showed the typical histological structures of the testis, while the treated groups showed multinucleated spermatids in addition to the deposition of amorphous eosinophilic material in the interstitial tissue, coagulative necrosis, in addition to apoptotic and sloughed spermatogonia in the lumen of seminiferous tubule. These results indicate that sodium fluoride with 300 ppm has toxic effects on organ body weights and on the histology of the gonads of adult’s male and female albino rats.

The disaccharides, consisting of sucrose, lactose and maltose, are hydrolysed into monosaccharides (D-glucose, D-galactose and D-fructose) by intestinal brush border enzymes: sucrase, lactase and maltase. The aim of this study to investigate changes in the brush-border membrane carbohydrate digestive enzymes. From intestinal mucosal scrapings of equine, brush border membrane vesicles were isolated. The results showed that sucrase, maltase and lactase are present in the equine small intestine. The activity of all three enzymes is highest proximally (in the duodenum and jejunum) and lower in the ileum. There was considerable variation between individual horses, however the majority showed highest disaccharidase activity in the jejunum, with some showing highest activity in the duodenum. Sucrase activity is highest in the jejunum and duodenum and lower in the ileum. Maltase activity is similar in all three regions, but slightly higher in the jejunum. Lactase activity is low in all three regions of the small intestine, slightly higher in the equine jejunum and duodenum than ileum. From this study, we can conclude that the equine small intestine digests disaccharides by the brush-border associated disaccharidases sucrase, maltase and lactase. Levels of sucrase and lactase are comparable to other species, but maltase is much higher.

The present study was aimed to determine the scolicidal effect of stem and root alcoholic extract of Punica granatum L. (Pomegranate) on the viability and fatty acids content of Ecinococcus granulosus protoscolices. The study elucidate the scolocidal effect of both stem and root extracts. Its seemed that the scolocidal effect of root extract was higher than that of stem extract ie. LC50 and LC90 of stem extract were 5 and 9 mg/ml respectively while LC50 and LC90 of root extract were 3 and 8 mg/ml respectively. GLC analysis of E. granulosus protoscolices was stated presence of nine fatty acids esters, which were Lauric (C12:0); Myrisitic (C14:0); Palmatic (C16:0); Stearic (C18:0); Archidic (C20:0); Behenic (C22:0), which were saturated fatty acids, and Oleic (C18:1); Linoleic (C18:2); Linolenic (C18:3) which were unsaturated fatty acids. Treating E.granulosus protoscolices with LC50 of pomegranate stem bark was showing slight and swing effect on fatty acid content, while treated the protoscolices with LC50 of root bark were resulted in obvious increase in short length fatty acids like Lauric, Myrisitic and Palmatic in compare with control group. In contrast the long chain fatty acids concentration like Oleic, Linoleic and Linolenic were decrease.

Pseudomonas (P.) aeruginosa possesses a variety of the virulence factors that may contribute to its pathogenicity, such as exotoxin A (toxA) and exoenzyme S (ExoS). The principal aim of this study was to find out the rapid method for identification of P. aeruginosa and to detect the toxA, exoS and16SrRNAgenes by Polymerase Chain Reaction (PCR) technique. Other aim on the other hand, the DNA sequencing was performed for phylogenetic tree analysis of 16SrRNA gene in local pathogenic P. aeruginosa isolates in comparison with NCBI-Genbank global P. aeruginosa isolates and finally submission of the present isolates in NCBI-Genbank database. According to the detection of the 16S rRNA gene, the study revealed that 29 (58%) and 32 (64%) of P. aeruginosa out of 50 swabs obtained from each wound and burn areas were positive. whereas in addition, the result of this study showed that the toxA gene was detected in 77% of P. aeruginosa isolated from the wound and 51% of P. aeruginosa isolated from the burn. whereas, the exoS gene was detected in 69% of P. aeruginosa isolated from the wound and 49% P. aeruginosa isolated from the burn. BLAST analysis showed that the 16S rRNA gene shared more than 99% homology with the sequences of P. aeruginosa. Furthermore, the phylogenetic tree analysis of the 16S rRNA gene indicated that (PA-IQw and PA-IQb) the 16S rRNA gene shared higher homology with other four P. aeruginosa isolates available in the GenBank. The homology of the nucleotides was between 99.9% and 100%.

Research was undertaken to establish an inventory of ticks on dogs in the north east of Algeria. In the first aspect of study, a survey aims to identify of Ixodidae infesting the dogs in bioclimatic different areas and to determine the risk factors. This work took place between 2006 and 2012. The results of the collections show that all the dogs, which were the subject of this survey, are infested by ticks during the period between March and August in different areas of the northeastern of Algeria. Rhipicephalus sanguineus is the predominant tick species. It has been observed with a frequency of 88 % in the area of El-Tarf, 100 % in Souk-Ahras, 95 % in the Tébessa region and 72 % in Guelma, (average of 89 %). Climatic conditions seem to play the essential role for this distribution of ticks. The other tick species collected are: Ixodes ricinus, Rhipicephalus turanicus, Haemaphysalis punctata and Hyalomma anatolicum. The latter were present with very low a proportion, which gives them the appearance of accidental parasitism in dogs. Rhipicephalus sanguineus has significant infestation intensity in spring and summer, peaking in August in the semi-arid region (Souk-Ahras). In humid regions (El-Tarf), the peak of infestation recorded by this arthropod is in April. The second aspect of study of the seasonal dynamics of Rhipicephalus sanguineus shows the seasonal nature (Spring-Summer) of the brown tick of dog.

The aim of this work is to study lamb births and mortalities in Algerian sheep Ouled Djellal breed distributed in different zones of Tébessa region, which is divided according to bioclimatic stage, staff in livestock and area agricultural vocation, into four distinct zones: northern (A, B), middle (C) and southern zone (D). During two years 2015-2016, birth numbers (BN) and mortality rates (MR) of 355 sheep flocks were recorded using a questionnaire. Concerning BN the total number was 21244 lambs representing a mean 59±31 per flock. No significant differences between the birth means of C and D (75±28 vs 83±30) were registered. Birth mean was significantly higher (P<0,05) in B (40±17) than A (29±10), when comparison with C and D, the births of A and B were highly significantly (P<0,001). According to (BN) the studied region were classified into 3 zone groups: (a) with high lambing rate (C, D); (b) with medium lambing rate (B); (c) with low lambing (A). In regard to mortality rates, the total rate was 24±6%. The (MR) in A (27±5%) was significantly higher (P<0,05) as compared to other zones (B) 24±4%, (C) 23±7% and (D) 22±4%. However, no significant differences between B, C and D were revealed. According to the results of (MR) the studied region was classified into two groups: (a) with low MR (C, D), (b) with high MR (A, B). Our result showed that zones influence the (BN) and (MR) in Tébessa region, and southern zones especially D seems the appropriate to practice breeding of Ouled Djellal breed.

This study aimed to investigate the impact of supplementing different levels of Nigella sativa oil in rations of growing lambs. In a feeding experiment lasted 90 days, 18 growing Ossimi lambs (6-7 months old) were randomly divided by weight into three equal groups (6 animals each). Individual animals in all groups were fed a uniform total mixed ration, offered at 3% of body weight, where the first group was without supplement (R1), while Nigella sativa oil was supplemented at 0.1 (R2) and 0.2% (R3) of dietary DM. Results indicated that additions of N. sativa oil didn’t influenced feed intake, but it increased average body weight gain and feed efficiency. Nutrients digestibility values and dietary nitrogen utilization were higher with N. sativaoil rations than control. Ruminal fermentation parameters showed comparable pH values among groups at 0, 3 and 6 hrs. of feeding. Ruminal NH3-N concentration was lower and TVFA concentration was higher for animal fed R2 and R3 rations than control. It’s concluded that N. sativa oil could be added at 0.2 % of the daily feed as a natural growth enhancer of lambs.

COVID- 19 is highly infectious disease where the first infected case reported in Wuhan city-China, then it was spread worldwide. The causative agent belongs to novel enveloped single linear positive-sense stranded RNA Coronavirus, which is also called SARS-CoV-2 and has an affinity to lung cells. The genetic analysis of SARS-CoV-2 suggested that this novehtm hgn l strain may be developed from the animal. origin by recombination between a bat SARS-like CoV and a coronavirus of unknown origin. The ability of rapid spread of SARS-CoV-2 virus from person to other is similar or even more than to other human viruses like influenza or plague leadding to be announced as a pandemic by WHO in 2020. The mortality rate in SARS-CoV-2 increased day by day and this led the scientists to search ways to control the virus. Most of the deaths in aged patients may be due to immune response complications where 70% of patients showed lymphopenia. This review, provided some details about structure, pathogenicity and immune response against SARS-CoV-2. The facts in this review lead to suggest that in most cases the death in SARS-CoV-2 may occur via loss of systemic inflammatory response control which leading to lung injury followed by pneumonia, acute respiratory distress syndrome (ARDS) and respiratory failure, hence the death especially in old patients. In concluding the early effective control of both innate and adaptive immunity may be the critical. key factor in protection against SARS-CoV-2.

A total of 1116 records Awassi ewes and 432 of Hamdania ewes were collected and which belong animals resource department, Faculty of Agriculture and Forestry at the University of Mosul for the years 2008, 2009 and 2010 to study the effect of genetic and non-genetic factors in milk production and some of its components from birth until weaning. The results showed significant effects (p≤0.05) for the breed and highly significant effects (p≤ 0.001) for the year, mother's age, sex, and type of birth in the daily milk production. There was a highly significant effect of year in milk fat, protein, and lactose. same there was a significant effect for age at weaning on birth weight, and highly significant effects for the breed, year, age of dam, sex, type of birth, and age at weaning on birth, weaning and weight gain from birth to weaning. The highest value for repeatability was 0.398, 0.309 in Awassi ewes for weight gain and in Hamdani ewes for daily milk yield respectively. Phenotypic and genetic correlation between protein and lactose in Awassi ewes 0.507 and 0.410, and in Hamdani ewes 0.641 and 0.157 respectively were highly significant.

Data of twenty one local breed bull calves (Sharabi and Janoubi) were collected from previous work for this study, their ages ranged from 8-18 month with initial live body weight of 125-300 kg. They were fed for 100 days period a standard ration which consisted of 60:40% concentrate to roughages ratio and contained 12.4% crude protein, 19.9% crude fiber and 2.2 Mcal/kg ME. Feed was offered at 3% of live body weight. Calves weights were sorted out into three groups, according to their means of body weight and were 140, 210 and 280 kg. The first group of calves had a significant increase daily gain more than the other two groups and were 1200, 850 and 830 g, respectively. Also, feed conversion rate of the first group was better than the other two groups, and were 6.2, 8.9 and 9.9 kg. ration/1 kg weight gain, respectively. Cost of feeding to produce one kg of weight gain in the first group was more efficient than the other two groups, and were 1860, 2670 and 2970 I.D., respectively. No differences were found in carcass traits among the three groups of calves. The results of this study suggest that it is better to choose local bull calves at live weight less than 200 kg for fattening purpose, to obtain more economical benefit.

The present study was conducted on 57 local breed cows suffering from various degrees of endometritis. The clinical examination included visual examination of vagina supported by uterine palpation per rectum; the laboratory examination included the bacterial isolation from the uterine swabs and histopathological examination of the uterine biopsies. Animals were randomly divided in to three groups of 15 cows each and 12 cows were considered as a control group received no treatment and observed for three consecutive estrous cycles. The first group was treated with a mixture of oxytetracycline (4 g) and tylosin (2 g), second group was treated with cephquenome sulfate 0.5 g, and the third group was treated with lugol's solution (30 ml) 2 %. These treatments were applied as a single intrauterine infusion and the clinical recovery was evaluated at the next estrous cycle by considering the absence of abnormal vagina discharge as an indicator of clinical recovery. Cows that showed clinical cure were inseminated artificially and the pregnancy diagnosis was preformed at least 75 days after insemination by rectal palpation. Retained placenta was the most important predisposing factor of endometritis 50.8 %, results of the bacterial examination demonstrated that E. coli was the most prevalence bacteria (27.4 %). Histopathological examination of uterine biopsy showed a high incidence ratio of chronic endometritis (42.1 %). Results of the treatment showed a higher response and conception rate in the second group (using of cephquenome) 73.3 % and 63.3 %, respectively, followed by first group (using mixture of oxytetracycline and tylosin) 60 % and 55.5 %, respectively, then the third group (using of lugol's solution) 40 % and 50 %, respectively. The lowest cure and conception rates were observed in the control group 25 % and 33.3 %, respectively. This study pointed out a positive relationship between the nature of the vaginal discharge and each of the bacteriological and histopathological examination and revealed the importance of the early treatment of endometritis especially using of cephquenome sulfate.

The prevalence of suppurative arthritis in one hundred sheep from both sexes and different ages were studied. Aspiration of synovial fluid from knee joint of animals showed signs of lameness with reluctant to move in addition to decrease in the body weight and loss of appetite. Physical and bacterial examination of the synovial fluid was revealed green color, turbid and containing pus. Mucin clot showed difference in degree of clotting, and increased number in leukocyte, neutrophile but decreased in lymophocytes and monocyte. The result showed that Streptococcus dysagalactiae was predominate 61.1% while Arcanobacterium pyogenes and Pseudomonas aeruginosa were the less 5.5%, also the result showed that all the strains were more sensitive to the Ciprofloxacin. This study is considered to be the first attempt to isolate bacteria from Sheep joints in Mosul-Iraq.

The current study included the possibility using fluorescent Acridine orange stain in the diagnosis of Babesia spp in cattle in Mosul city/Iraq, this dye is easily applied and takes no more than 2-5 minutes in the diagnosis of Babesia spp using of fluorescent microscope versus 45 minutes of Giemsa stain by using light microscope. The benefit of Acridine orange stain is in its uses in epidemiological and survey studies and for the control programs against Babesiosis but it is considered to be of little value in study of morphological features of small blood protozoa with low parasitemia comparing with the golden Giemsa stain in the study of morphological and specifications of Babesia spp.
