The aim of this study was to evaluate the effect of Tris-based extenders containing glycerol and egg yolk on the motility and viability of chilled ram semen collected during non-breeding season. Nine ejaculates from three healthy rams in non-breeding season were collected by artificial vagina method. The semen was diluted with Steridyl (ST), Triladyl (TRY) or Tris-based extender containing 5 % glycerol and 5% egg-yolk (TGGY) to a final concentration 200x109 spermper ml. Semen samples (n=9) for each extender were stored at 5 0C for 72 hours. Motility and viability were evaluated at 0, 6, 24, 48 and 72 h of storage. The results were statistically processed and the influence of extender and time of storage were recorded. | Effect of extenders containing glycerol and egg yolk on motility and viability of chilled ram semen collected during non-breeding season
