The aim of this study was to investigate the effect of season on embryo production in Iraqi local black goat. 599 female genital system of Iraqi local black goat were collected from AL-Fallujah abattoir, AL-Anbar province during the period from July 2010 to the 1st July 2011. The oocytes were collected via aspiration and slicing. Only good and fair quality oocytes were selected for in vitro maturation. Fresh semen were used from two Bucks of proven fertility for fertilization . TALP , MEM , and TCM-199 culture media were used of in-vitro maturation (IVM) and in-vitro fertilization (IFV). It has been shown that high recovery and maturation rate 87.3% and 45.6% respectively were observed at breeding season as compared with recovery rate 72.5% and maturation rate 35.2% respectively in non-breeding season. There was a significant difference (P˂0.05) in recovery rate and maturation rate between different season. It has been found that fertilization rate was 60.05% in breeding season. While it has 33.9% in non-breeding season. There was a significant difference in fertilization rate (P˂0.05) between breeding and non-breeding season. Blastocyst obtained during breeding season was 56.41% , while it was 43.24% in non-breeding season. There was a significant difference (P˂0.05) between different season. It was concluded that there is an effect of season on oocyte recovery.

The effects of diets containing Gundelia (Gundelia tournefortii L.), which is a wild plant species in Middle East countries, on performance rate and health parameters of Iranian Afshari breed sheep were studied for the first time. Totally 60 fattened sheep in three groups were studied via receiving different diets and performance rate, hematological and biochemical parameters, which are related to animals health and also are indicator for diet's efficiency, for each groups were evaluated via laboratory methods. The results of current study show that performance rate and/or hematological and biochemical parameters in group which received diet containing Gundelia hay and grain were same as control group which received standard diet, but performance rate in group which received Gundelia hay singly was lower than other groups. Number of White Blood Cells, differential number of neutrophils and lymphocytes, concentration of plasma proteins and fibrinogen, serum concentration of total protein, cholesterol and lipase had increases in treatment groups versus control group and number of red blood cells, serum concentration of glucose, albumin and blood urea nitrogen had decreases in treatment groups versus control group. Given to low costs and high performance rate of Gundelia hay plus grain diet, which is related to presence of high amount of carbohydrates and fatty acids in it, this diet can be considered as an efficient diet for fattened sheep but more studies are need. Study on production's quality in animals are receiving Gundelia's diet is suggested as a subject for next studies.

Research on genetic polymorphism of growth hormone (GH) and receptor growth hormone (rGH) has not been done in crossbred of Limousin cattle, so it is interesting to be examined. Blood samples were taken from 14 Madura calves were artificially inseminated with Limousin cement. DNA amplification is done by using Polymerase Chain Reaction (PCR) method, Restriction Fragment Length Polymorphism (RFLP) method to determine the genotype. DNA sequencing was done to determine nucleotide sequences of GH unit genes. The results showed that identification of GH and rGH gene polymorphisms was done by breaking DNA fragments from 432 and 298 bp in Madura and Limousin cattle (Madrasin) ie, L and V alleles have a frequency of 0.67 and 0.33 for the GH gene, respectively. This proves that the crossed-breeding of Madrasin have V allele that is not owned by the Madura cattle. While in the rGH gene, the A allele is 0.92 and the G allele is 0.08, with the frequency of the A allele larger than the G allele. This research concluded: that GH and rGH undergo changes on polymorphisms in Madrasin cattle can be used as a basis for selection.

The current study was conducted to investigate the impacts of active and passive immunization against synthetic inhibin-α subunit and steroid-free bovine follicular fluid, respectively, on reproductive hormones profile out of breeding season in Iraqi Awassi ewes. Follicular fluid was aspired from mature bovine follicles, treated with activated charcoal, used for immunization of male rabbits, and obtaining of SFBFF antiserum. Forty non-pregnant Awassi ewes were allocated into 4 groups (n = 10 each). At day 38 of experiment, ewes were treated with intra-vaginal sponge impregated with medroxyprogesterone acetate 60 mg for 12 days. Ewes were treated at 0, 28 and 50 days with 4, 2 and 2 ml of normal saline (control; C-ve), 400, 200 and 200 µg of ovalbumine (C+ve), 400, 200 and 200 µg of inhibin (SI group), and 4 ml of normal saline at 0 day, and 4ml and 2ml of SFBFF antiserum, at 28 and 50 days, respectively (AI group). Blood samples were collected at 24 and 48 hours before and after sponge withdrawal for assessment of FSH, LH, inhibin-B, Activin-A, E2 and P4. Before sponge withdrawal, FSH level increased in SI ewes, whereas only after sponge withdrawal, FSH, LH, activin-A and E2 levels increased in SI and AI ewes. Opposite results were shown of inhibin-B level. In conclusion, active or passive immunization against inhibin in Awassi ewes could augment reproductive functions out of breeding season in Iraqi Awassi ewes.

The recent study was designed to estimate the effect of season on dogs' semen parameters in mature and pubertal males, before and after hormonal adding and precede the sperms viability after collection. Twenty local dogs were divided into two equal groups the first one aged between 2-3 years which represent the mature dogs group, and the second group aged 9-12 months which considered as newly pubertal males. This study was done in dogs cages in College of Veterinary Medicine – University of Baghdad from 1/2/2015 to 1/2/2016. The semen was collected by using artificial vagina twice weekly. The physical examination (semen volume, colour, odour, debris and pH) and also the microscopical examination (mass motility, individual motility, sperm numbers, viability and deformities) and precede both the viability of sperms every hour till ceased of individual motility and the effect of adding of oxytocin and prostaglandine f2α. The herein study indicated that there were a significant decrease in sperms mass motility, individual motility, sperms numbers and viability during summer season, nevertheless, the deformities increased significantly during the summer in both males groups. The deformities show significant differences between mature and pubertal males. The individual motility indicated an increase after hormonal adding to the semen, the individual motility also ceased after 12 hrs from collection in all seasons. This study concluded that the male dogs could breed during the different seasons of the year, and the summer season had negative effect on male reproductive fertility. The hormonal adding lead to increase the individual motility also the maximum period of survival of the sperms after collection not extended more than 12 hrs.
