提高黄牛及杂种牛受胎率的研究

Study of Improvement of Conception Rate in Yellow Cattel and Hybrrd Cattel

对471头黄牛和杂种牛进行提高受胎率的试验。结果表明,用LRH-A处理的母牛情期受胎率和总受胎率分别为56.69%和65.93%,明显高于对照组(24.40%和49.21%)(P<0.05);用hCG处理的母牛情期受胎率和总受胎率分别为53.33%和72.72%,明显高于对照组(33.69%和52.54%)(P<0.05)。

To 471 oxen, the mixed stud bull carries on enhances the conception rate the experiment. The result indicated that the cow sentiment time conception rate and the total conception rate processes which with LRH-A respectively were 56.69% and 65.93%, and were signficantly higher, than control group（24.40% and 49.21%）（P〈0.05） ; The cow sentiment time conception rate and the total conception rate processes which with hCG respectively are 53.33% and 72. 72%, and were signficantiy higher than those in the cow of control group（33.69 % and 52.54%）（P〈0.05）.
