Abstract: In two trials involving the artificial insemination of 194 ewes, the fertility of ram semen was examined following freezing, either in pellet form or in straws, and after storage in a chilled state (15°C) for up to 16 hours. Estrus was synchronized in ewes by intravaginal sponge (MAP) treatment for 14 days. At sponge removal 600 IU PMSG was injected and the ewes received two inseminations 50 and 60 hours later. Fertility was assessed at lambing. In trial 1, the mean lambing rate of 52% () for semen frozen in pellets was higher than 29% () for semen frozen in straws but this difference was not significant. In trial 2, ewes inseminated with chilled semen and semen frozen in pellets had lambing rates of 83% () and 55% () respectively (P<0.001). |
