摘要 用流式细胞仪分离荷斯坦奶牛的精液,检测在冷冻前和冷冻后分离的精子活力。同时,对不同牛群利用分离得到的性控鲜精和性控冻精进行人工输精,对其人工授精效果和性别控制效果进行观察。结果表明:分选后冻前精子活力达到0.60~0.67,分选后解冻精子活力达0.31~0.39;育成牛群性控鲜精输精的情期受胎率高于使用性控冻精输精,经产母牛群性控鲜精输精的情期受胎率高于使用性控冻精输精,但差异均不显著(P>0.05);使用性控鲜精、性控冻精进行人工输精,育成牛群情期受胎率高于经产母牛群,且差异显著(P<0.05);产母犊率差异不显著(P>0.05);用性控精液人工授精的奶牛早期流产率高于非性控精液,但差异不显著(P>0.05)。
