摘要： 应用产后1h和24h的初乳及三合激素诱导产后高产奶牛提早发情。结果表明，应用产后1h的初乳、产后24h的初乳及三合激素处理后，奶牛的发情率分别为90.00%、35%和100%；奶牛的配种受胎率分别为38.75%、41.67%和35.00%。应用产后1h的初乳处理产后高产奶牛的发情率较高，与三合激素处理的结果差异不显著（P>0.05）；三种方法处理后奶牛的受胎率差异不明显，结果相似(P>0.05)。

Abstract: In this experiment，author applied the postnatal colostrums of 1 hour ,24 hour and tris～hormone to induce the estrus or breeding for the postnatal high～yield dairy cattle。The postnatal high～yield dairy cattle was treated by the postnatal colostrums of 1 hour and 24 hour，the heating rate was 90.00% and 35% respectively. And after breeding，the conception rate separately was 38.75% and 41.67%. This results showed that the postnatal high～yield dairy cattle was treated by the postnatal colostrums of 1 hour , the heating rate was higher than that of colostrums of 24 hour (P<0.05). The difference was not remarkable (P>0.05) between the postnatal colostrums of 1 hour and 24 hour for the conception rate. To the heating rate and conception rate, the effects of the postnatal colostrums of 1 hour was same as that of the tris～hormone(P>0.05).
