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)。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>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).
