Effect of Extenders Containing Glycerol and Egg Yolk on Motility and Viability of Chilled Ram Semen collected during Non-Breeding Season (original) (raw)

The study evaluates the efficacy of Tris-based extenders containing glycerol and egg yolk on the motility and viability of chilled ram semen collected during the non-breeding season. Conducted on nine ejaculates from three healthy rams, the semen was diluted with three extenders and stored at 5°C for 72 hours. Results indicated a significant decline in motility and viability after 6 hours, while extenders did not consistently differ in performance until 48 hours. The findings suggest that the tested extenders provide protective effects on ram semen, highlighting the influence of storage time over extender type on semen quality.
