Iraqi Journal of Veterinary Sciences, Volume 20, Issue 1, Pages 1-8

The study was designed to investigate the subchronic toxic effect of cadmium chloride administered orally on alanine aminotransfearase (ALT), aspartate aminotransfearase (AST) activity and certain tissues in adult male rabbits. The animals were randomly divided into 3 groups (6 animals lgroup). The first and second groups were administered cadmium chloride (30 and 60 mg/kg respectively). The third group was given distilled water and served as a control. All groups were treated daily by gavage needle for a period of eight weeks. The results demonstrated that cadmium chloride(30 and 60 mg/kg) caused a significant increase in alanine aminotransfearase activity in treated animals,
while a significant increase in aspartate aminotransfearase activity was reported only in animals administered cadmium chloride at a dose of 60 mg/kg.
Histologically, cadmium-treated groups showed lesions in liver and kidney. These lesions were more severe in animals treated with 60 mg cadmium chloride than those treated with 30 mg cadmium chloride.

Iraqi Journal of Veterinary Sciences, Volume 20, Issue 1, Pages 9-21

To explore the various constituents of the trachea of the local awasi sheep and black goat, gross anatomical, histological and morphometrical studies had been carried out.
The study revealed that the average length of the trachea is directly proportional to the number of tracheal rings and it was also noticed that the length, diameter and wall thickness of the trachea of the sheep were greater than those of black goat. These parameters decreased gradually toward the posterior third of the trachea in both species. The free dorsal ends of the tracheal rings of the sheep overlapping each other at the cranial third, but they gradually move a part at the mid – third, and they become again very close to each other and run side to side dorsally to forming a dorsal crest at the caudal third. However, the two free ends of tracheal rings of the goat remain considerably apart throughout the entire length of the trachea forming a (U) shaped configuration. The cartilaginous rings were so oriented that they disposed one beside the other at the ventral and lateral aspects of the tracheal wall. But they overlapping each other at the dorso – lateral aspect of the tracheal wall in both species. Three main cells were detected in the surface epithelium of the trachea of both species (ciliated columnar cells, basal cells and goblet cells), another cell type was restricted to the posterior third of the trachea of both species. The tracheal glands were found to be compound, mixed tubulo – acinar type. The majority of the secretory units were mucous, the others were serous. Most of the tracheal glands occupied the triangular area between the successive tracheal rings particularly at the medial side of the ventral aspect of the trachea. The density of the tracheal glands decreased gradually anterio – coudally in the both studied species. The percentage of goblet cells in the trachea of sheep was greater than that of goat, and decreased gradually toward the lungs in both species.

The aim of this work was to explore the different types of carbohydrates histochemically in the trachea of local Awase sheep and to compare it with that of the local black goat. Ten tracheas from each sheep and goat were used for this study. Different histochemical methods were used to explore types and locations of carbohydrates in trachea’s wall of both animals. It was observed that the amount of mucus secreted from the anterior third of trachea was comparatively greater than that of the middle and posterior thirds due to its higher content of
tracheal glands and goblet cells. The carbohydrate histochemistry of different constituents of the trachea showed that there was no noticeable difference between the two studied species. However, the glycogen was found in a greater amount in goat's trachea in comparison to sheep. The goblet cells and the mucous secretory units of the trachea showed a considerable amount of carboxylated glycoprotein together with a little amount of other forms of carbohydrates. The mucus that covers the lumen of the trachea contained almost all the carbohydrate substances with the exception of neutral glycoproteins. Chondrocytes contain glycogen, sulphated and neutral glycoproteins but didn't show any form of GAGs, whereas, the territorial matrix of the cartilage contains a mixture of carboxylated and sulphated GAGs with the predominance of the latter, but glycoproteins could not be detected. The interterritorial matrix contained mainly carboxylated glycosaminoglycans together with a little amount of glycoproteins. The columnar cells and the basal surface epithelial cells showed no reaction to any form of carbohydrates.

Iraqi Journal of Veterinary Sciences, Volume 20, Issue 1, Pages 49-58

The effect of methionine supplementation on growth performance of 180 briolers type (Cobb) during growing period (1-21) days, fattening period (22- 42) days and the entire rearing period (1- 42) day, and carcass traits were examined. Three levels of methionine (0.10, 0.15 and 0.20%) were supplemented to corn-
soybean diet and compared with a normal diet (as control), for broiler feeding. Increasing methionine supplementation levels significantly improved weight gain and feed conversion efficiency, particularly at (0.15 and 0.20%) levels. Feed intakes were not significantly different among treatment groups. Carcass yield and breast yield increased at (0.15 and 0.20%) levels of methionine addition (P<0.05). Abdominal fat content and liver relative weights were not significantly different among the various treatments due to different methionine levels. Results of this experiment suggest that addition of methionine to corn-soybean diets had improved performance and carcass traits of broilers.

Iraqi Journal of Veterinary Sciences, Volume 20, Issue 1, Pages 65-70

Twenty draught stallions, 4-10 years old, were used in this study. The horses were divided into two equal subgroups (10 horses for each) to compare the
efficacy of a single dose of Ivermectin (oral paste), 0.2 mg/kg B.W., with a single dose of Oxibendazole (oral suspension), 10 mg/kg B.W. The parameters that used were EPG, RBCS, Hb and PCV pre- and post-treatment. Results indicated reduction in EPG to zero within 14 days after treatment with Ivermectin, while there were gradual reduction in EPG without complete absences of eggs after 21 days of treatment with Oxybendazole. Also there were increase of RBCS, Hb and PCV after 14 days of treatment with Ivermectin and after 21 days of treatment with Oxybendazole. Results of evaluation of therapeutic agents indicated that Ivermectin in a dose of 0.2 mg/kg B.W. given as oral paste as a single dose was more effective than Oxibendazole in a dose of 10 mg/kg B.W. given as oral suspension as a single dose in the treatment of draught horses affected with gastrointestinal and lung worms.

Iraqi Journal of Veterinary Sciences, Volume 20, Issue 1, Pages 71-80

A total of 150 draught stallions 4-10 years old were used in this study, included 125 horses were naturally suffered from gastrointestinal and lung worms infection and 25 clinically normal draught horses served as control group. Coprological examinations revealed that draught horses were infected with many specieses belonged to nematodes and cestodes. The mean EPG were 2020 in McMaster method. Results indicated that diseased draught horses exhibited emaciation, rough coat, pale mucous membrane, black spots on the gum & lip, loss of appetite, diarrhea and/or constipation, worms with feces, mucous with feces, colic, anal pruritis, moist ralse, coughing and strong heart beat. Statistically, significant increase (P<0.01) were encountered between respiratory and heart rates of diseased horses in comparison with control, while there were no changes in body temperature among the two groups. Significant decrease (P<0.01) were encountered in the RBCS, Hb and PCV values of diseased horses, and significant increase (P<0.01) were also encountered in the sedimentation rates of RBCS, while there were significant increase (P<0.01) in WBCS and eosinophils. Results of biochemical tests indicated decrease in total protein and albumin values, the decrease was statistically significant (P<0.01). Levels of BUN and AST were increased significantly (P<0.01), while there were no significant changes observed in ALT levels. Presence of worms causes macroscopical and histopathological lesions in many organs of dead horses.

Among these 100 animals were naturally suffered from babesiosis and 25 clinically normal horses served as control, three dead infected horses served for gross pathological and microscopical changes. Results revealed that diseased horses were affected with the acute form and they exhibited general weakness, loss of appetite, congestion of mucous membranes with petechial hemorrhages in some of them, pale and/or icteric mucous membranes were seen in others, hemoglobinurea, edema of fetlock joint and supraorbital fossa, colic with signs of diarrhea and constipation, profuse sweating, dehydration, rough coat, ticks were observed on various parts of the body. Statistically significant increases were encountered between body temperature, respiratory and heart rates and significant decrease were detected in the RBCS, Hb, PCV, platelets count and fibrinogen. However statistically significant increase were encountered in the sedimentation rate of RBCS, clotting time, prothrombin time and activated partial thromboplastin time. Anemia was macrocytic hypochromic type, the percentage of parasitemia ranged between 6-28 %. Reticulocytes detected in blood smears prepared from blood of diseased animals with mean of 3.07 %. Significant increase WBC count, lymphocytes and significant decrease in neutrophils were showed in diseased animals. The results of biochemical tests revealed significant increase AST, ALT, ALP, total bilirubin, blood urea nitrogen and icteric index with significant decrease in total protein and calcium. The results indicated that equine babesiosis caused gross pathological and microscopical changes in different organs of dead animals.

This study was conducted to determine the possibility of 0.5% H2O2 on drinking water, for the induction of oxidative stress status in mature female rats. Moreover, this study deals with the role of this stress in initiation and development of atheromatus lesions in these animals. Oxidative stress has been investigated via tissue malondiadehyde (MDA) & glutathione (GSH) (aorta, heart and liver) as indirect lipid peroxidation index. For atherogenous follow up, light and electron microscopical techniques have been applied.
The result elucidate significant elevation in lipid profile parameters namely cholesterol, Triglycerides TG, Low density lipoprotein LDL-C, Very Low density lipoprotein VLDL-C, atherogenic index and a significant reduction in High density lipoprotein HDL-C, level in all experimental animals. Parallely, this study revealed significant rising in tissue MDA concentration, concomitant with significant depress in tissue GSH level in all studied animals.

The study revealed presence of giardia cyst in the feces of animals which was examined at 7%, 4.5% and 5.45% in the direct method for sheep, goats and cattle respectively, while 15.5%, 16.5% and 21.81% in concentrated method respectively at the same animals.
No significant differences recorded in rate of infection between different species of animals, although higher percentage of cyst was eliminate in cattle feces. There was no significant effect of age and type of breeding on rate of infection. However the animals in late stage of pregnancy and early stages of milking eliminated higher percentage of cyst in their feces, especially in goats. Diagnosis of gastrointestinal nematode eggs with giardia was found to be 7.5%, 4.5 and 0 % in sheep, goats and cattle, respectively and with Eimeria; 3.5%, 11% and 5.45, in same animals, respectively. The most obvious clinical signs found were pasty feces mixed with mucous, emaciation and easily detached wool and hair.
