摘  要:
应用激素诱导母牛超数排卵,提高母牛繁殖率。选择3个试验组合,即FSH+LHRH-A3试验组、PMSG+ APMSG试验组和三合激素+ LH试验组。选择条件大致相同的空怀母牛36头,随机分为3组,每组各12头,饲养管理基本一致。结果FSH+LHRH-A3试验组母牛12头,情期受胎9头,受胎率75.0%,产犊12头,其中产双胎3头,双胎率为 33.3% ;PMSG+ APMSG试验组母牛 12头,情期受胎 8头,受胎率为 66.7%,产犊 8头,其中产双胎1头,双胎率为12.5%;三合激素+LH试验组母牛12头,情期受胎6头,受胎率为 50. 0%,产犊 6头, 双胎率为零。

摘  要:
Thirty - six dry cows with similar conditions were selected and divided into three 12 cow groups to investigate the effects of hormone on superovulation and cow's reproductivity under the same feeding condition, three groups received FSH + LHRH- A3, PMSG + APMSG, and tri - hormone + LH treatment. 9 of 12 cows in FSH + LHRH - A3 group were pregnant with pregnancy rate of 75 % and produced 12 calves including twins from 3 cows with twinning rate of 33. 3 %; 8 in PMSG + APMSG group were pregnant with pregnancy rate of 66. 7 % and produced & calves including twins from 1 cow with twinning rate of 12. 5 %; 6 in tri - hormone + LH were pregnant with pregnancy rate of 50. 0% and produced 6 calves without twins.
