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 ...

ارزیابی عملکرد تولیدمثلی میش‌های افشاری با استفاده از روشی کوتاه مدت در هم زمانی فحلی در خارج از فصل تولیدمثلی
Estrus synchronization is a valuable management tool that has been employed in enhancing reproductive efficiency in ewes. This study was conducted to investigate the reproductive performance of ewes with short and long-term estrous synchronization programs accompanied by eCG or GnRH during the non-breeding season. A total of 48 Afshari ewes were randomly selected and divided into two groups. In...
