应用"性控胶囊"对121头奶牛进行冷配,冷配受胎率平均达到70%。(有记录的)产犊41头,其中母犊30头,公犊11头,母犊率为73.17%。对使用与未使用"性控胶囊"进行奶牛冷配的情期受胎率进行了统计,分别为56.76%和57.77%,差异不显著。对使用了"性控胶囊"的成年牛与青年牛的情期受胎率进行了统计,分别为40%、68.18%,差异极显著(p﹤0.01)。因此使用"性控胶囊"可以显著提高母犊率,尤其在青年牛的应用效果好,可在奶牛生产中大量推广应用。
Abstract：121 dairy cows with AI were given "sex control capsules, and the pregnancy rate is 70%. Among them, 41 cows gave calves, 30 female calves and 11 male calves, the female calves rate is 73.17% .The pregnancy rates are 56.76% and 57.77% with or without "sex control capsules", and there is no significant difference. But the pregnancy rate for cows and heifers are 40% and 68.18% with "sex control capsules, and the difference is significant(p<0.01). Therefore, By using "sex control capsules", much more female calves are given, especially for heifers. This Product can be well used in dairy cattle production.
