摘要/Abstract

Abstract: This experiment was conducted to study the effects of measurement time of CIDR，different models of feeding and management，repeat superovulation and oestrus time on superovulation in sheep.The results showed that the average number of available embryos of the 10 days was significantly higher than those of the 13 days （P＜0.05）.In addition，there were extremely significantly differences on the rate of available embryos between the 10 and 13 days of CIDR （P＜0.01）.The average number of available embryos and available embryos rate of drylot feeding group were extremely significantly higher than those of pasture feeding group （P＜0.01）.The optimal result of repeated superovulation was two times，and there were no significant differences between the second and the third times （P＞0.05），but there were significantly differences compared to other forth times （P＜0.05）.The quality of embryos in the group of 24 h after superovulation was the best.In conclusion，the measurement time of CIDR，the pattern of different feeding and management and repeat superovulation had significantly effects on sheep superovulation，and the best quality embryos of sheep was in 24 h oestrus after superovulation.
