摘要
[目的]我国发展肉牛养殖具有较大的潜力,为了更好地开展肉牛杂交改良工作,[方法]我们对一次前列腺素法、孕激素阴道栓法、补充少量促卵泡素诱导产双胎法进行了同期发情技术试验,[结果]表明处理牛同期发情率都在90%以上,取得了较好的效果。[结论]说明周期发情技术在肉牛繁殖上应用具有明显提高繁殖率。
To improve the reproduction rate in beef cattle crossbreeding, three kinds of estrus synchronization treatment methods, i. e PG treatment, progesterone vaginal suppository and FSH were compared. The results indicated estrus rate of three treatment were all above 90%. It means estrus synchronization could improve the reproductive rate.
