Artificial insemination in sheep - comparison of storage time, dose rate and insemination technique



Artificial insemination in sheep - comparison of storage time, dose rate and insemination technique



Proceedings of the New Zealand Society of Animal Production 46: 229-232



Trials undertaken at Rotomahana in 1984 and 1985 examined factors involved in sheep AI and provided a link between Rotomahana and a commercial AI programme. Semen collected and diluted by the New Zealand Dairy Board gave similar CRs (46%) to semen collected at Rotomahana (42%). Results in 1984 indicated that there was a small but non-significant decrease in CRs with semen storage time up to 15 h (5 h, 68%; 10 h, 61%; 15 h, 57%).
