湖羊和小尾寒羊同期发情效果研究
The Chinese Livestock and Poultry Breeding(2018)
Abstract
为对湖羊和小尾寒做同期发情处理,研究其同期性和人工授精效果.选择湖羊和小尾寒羊各120只,采用"CIDR+PG+PMSG"同期发情方案,观察其发情效果,并对同期发情效果好的受体羊进行细管鲜精人工授精.同期发情处理后,在撤栓后湖羊组和小尾寒羊组的发情率分别为88%(106/120)和87%(104/120),两者差异不显著(P>0.05).在母羊发情后经行2次细管鲜精输精,湖羊组和小尾寒羊组受胎率分别为83%(88/106)和84%(87/104),两者差异不显著(P>0.05).
