摘　　要：饲喂 PEP(含矿物质和维生素的添加剂 )结合激素处理 15 4头产后乏情母牛 ,以期诱导发情。结果表明 :饲喂 PEP30 d组结合激素处理比未处理对照组极显著 (P<0 .0 1)提高发情率(10 0比 6 5 .6 )和繁殖率 (84比 4 6 .9 ) ,比单独的激素处理组极显著地 (P<0 .0 1)提高发情率 (10 0 %比 75 % ) ;单独饲喂 PEP(P)组比对照组可显著 (P<0 .0 5 )提高发情率 (87.3%比 6 5 .5 % )和繁殖率 (76 .4 %比 4 6 .9% ) ,激素处理结合饲喂 PEP(P- H)组可极显著 (P<0 .0 1)高于对照组的发情率 (93.6 %比 6 5 .5 % )和繁殖率 (78.7%比 4 6 .9% ) ,但 P组和 P- H组间的发情率、受胎率和繁殖率均差异不显著 (P>0 .0 5 )。The results show that 30 d feeding PEP combing additional hormone treatment significantly increased ( P <0 01) in estrus (100% versus 65.5%) and reproduction rate (84% versus 46.9%) than control, it also significantly higher ( P <0.01) than single hormone treatment in estrus rate (100% versus 75%) and in reproduction rate (84% versus 46.9%). Hormone treatment combining feeding PEP could cause marked effect ( P <0.01) on estrus (93.6% versus 65.5%) and reproduction rate (78.7% versus 46.9%) than control.
