Cryopreservation of chicken semen is crucial for poultry breeding and genetic preservation, yet post-thaw fertility remains low. In a randomized design, the effects of an aloe vera-based extender and two thawing protocols (5 ◦C for 30 s vs. 75 ◦C for 5 s followed by 5 ◦C for 20 s) on semen quality a ...

Anti-Müllerian hormone (AMH), produced only by granulosa cells, is a biomarker for ovarian reserve in sheep. This study compared AMH levels in two Slovenian breeds: Istrska pramenka (IP), a seasonal breeder, and Jezersko–Solčava (JS), which reproduces year-round. Blood serum samples from 78 sheep we ...

A challenge in freezing semen for short and long-term availability is avoiding damage to intact spermatozoa caused by the freezing process. Vitrification protocols provide better results through less manipulation of semen and shorter freezing time compared to slow freezing techniques. Our research w ...
