Induce of estrus in nonbreeding season in Iraqi black goats

Abstract

The study was conducted on 15 local Iraqi goats, presented in the farm of college veterinary medicine, Al-anbar university during the period from 4 March ,2013 to 4 April ,2013.The age of animals ranged between 3 – 4 years old. The animals were divided into 3 groups . The 1st group was injected 10 mg I/m PGF2α . The 2nd group were injected 2 mg I/M estradiol Benzoate, The 3rd group were injected 2ml physiological saline. The animal were put under observation within 72 hr. for detection of estrus. The doe showed estrus inseminated with fertile buck. The result showed that the animals showed estrus was 80% (4/5) in PGF2α treated group, While it was 40% (2/5) in estradiol treated group , it was zero in control group. There was a significant difference (P<0.05) between different group. In consideration the method of detection of corpus luteum and follicle , the laparotomy showed accuracy of (100%) as compared with ultrasonography( 50% ).It was concluded from the study that PGF2α was the best drug for induction of estrus in non- breeding season in Iraqi goats. Laparotomy was the best method for detection of ovarian structures.
