Timing Ovulation in Ewes Treated with Ovsynch Different Times of PGF2 αInjection during the Breeding Season
This study was carried out at Sakha Animal Production Research Station, during the period from Oct., 2009 to Sept., 2010. Forty Rahmani ewes were divided into three treatment groups: the 1st, 2nd and 3rd treatment groups were intramuscularly injected (Day 0) with 1 mL GnRH analogue followed by an intramuscular injection with 0.7 mL PGF2α5 (G1), 6 (G2) or 7 (G3) days later. A second dose of 1 mL...
متن کاملInduction of estrus during the non-breeding season in Egyptian Baladi goats.
The induction of estrus during the non-breeding season was investigated in 100 Egyptian Baladi goats (Capra hircus). All animals assigned to treatments had low progesterone concentrations (<0.5 ng/ml) tested 2 times 10 days apart to confirm anestrous condition. Animals were assigned to three experimental groups. A group of animals received subcutaneous norgestomet ear implant for 11 days and a ...

متن کاملArtificial Control of Estrus and Ovulation in Female Yaks
Introduction Yaks are seasonal breeders and the breeding season lasts from July to October. If the females do not show obvious estrus in a particular breeding season, they will express estrus in the next breeding season or in some cases not until several breeding season later. The observed estrus rate of yaks is rather low, and the postpartum period is long. Most females deliver calves once eve...
متن کاملInduction of Estrus, Ovulation and Fertility in Prepuberal Gilts
Induction of synchronized estrus and ovulation in prepuberal gilts is utilized in our laboratory to study factors influencing fertility and early embryonic development. Prepuberal females provide an inexpensive source of fertilized eggs, and they are not complicated by the presence of estrous cycles. Thus, estrus inducing treatments can be applied at any time. In the first of four experiments r...
