摘要
几年来 ,我们应用三合激素、氯前列烯醇及氯前列稀醇配合孕马血清处理 1 56头乏情母牛 ,结果 3组的催情率分别为 84.8%、79.5%和 86.9% ,同时配种后第一期受胎率分别为 4.4%、32 .2 %和 48.4%。试验表明第三组的催情率和受胎率都比较好 ,是提高母牛受配率的有效方法之一。
non-estrous famale cattle were treated with3-hormone package in- cluding estradiol,progesterone and testosterone,chloroprostaglandenol ( CPG) and combination of PMSG and CPG in the study to investigate the effects of hormones on conception rate.The result showed that the estrous rate of3groups were84 .8% ,79. 5% and86.9% respectively,the conception rate after first mating of3groups were 4 .4 % ,32 .2 % and4 8.4 % ,and the3rd group demonstrated the better estrous and con- ception rate,which is the effective method of increasing conception rate.
