中文摘要:

      [目的]为探讨激素生源2+1在水牛同期发情中的应用效果.[方法]利用激素生源2+1对48头母水牛在不同季节进行了同期发情处理研究.[结果]表明:同期发情效果受季节环境因素影响较大,夏季(6～8月)同期发情处理22头,14头表现发情,发情率为63.6%;秋季(9～11月)同期发情处理26头,20头表现发情,发情率为76.9%,总发情率70.8%(34/48).并在不同季节进行了同期发情人工受精配种比较,发现夏季和秋季的水牛同期发情人工受精配种受胎率差别较大(P≤0.01),分别为16.7%和33.3%.[结论]"生源激素2+1"在水牛同期发情中的应用虽有一定的效果,但本次试验牛只较少, 目前很难得出一个合理的结论,其应用效果仍需进一步研究探讨.

      To explore the effect of hormone Shengyuan 2+1 on estrus synchronization in water buffalo,48 buffalo cows were selected to induce estrous synchronization with Hormone Shengyuan 2+1 in different seasons.The effect of estrus synchronization was significantly influenced by seasonal environmental factors.22 buffalo cows were induced estrous synchronization in the summer(June~August) and 14 showed oestrus,estrus rate was 63.6%.26 buffalo cows were treated in the fall(September~November) and the number of estrus ...
