摘要/Abstract

摘要： 为研究有效精子数量对吉林马母马情期受胎率的影响,于2018—2020年选取健康且发情周期正常的300匹吉林马母马进行试验,采用子宫体常规输精和子宫角深部输精方式及不同有效精子数量对吉林马母马进行人工授精。结果表明,子宫体常规输精一次有效精子数达2×10⁸个以上或子宫角深部输精一次有效精子数达0.5×10⁸个以上,吉林马母马情期受胎率均可达60.00%以上;子宫角深部输精方式吉林马母马平均情期受胎率为69.80%,子宫体常规输精方式吉林马母马平均情期受胎率为45.78%,二者差异极显著（P<0.01）。这说明采用子宫角深部输精能显著提高吉林马母马情期受胎率,显著降低一次输精有效精子数量,提高种公马精液利用效率。

Abstract: In order to study the effect of effective sperm quantity on the pregnancy rate of Jilin mares during estrus, 300 healthy Jilin mares with the normal estrus cycle were selected for the experiment in 2018—2020. Jilin mares were inseminated by conventional insemination of uterine body, insemination in deep uterine horn and different effective sperm quantity. The results showed that when the number of effective sperms was more than 2×10⁸ with conventional insemination of uterine body or the number of effective sperms was more 0.5×10⁸ with deep uterine horn insemination, the conception rate of Jilin mares in estrus could reach more than 60.00%. The average conception rate in estrus of Jilin mares with deep uterine horn insemination was 69.80%, and that of Jilin mares with conventional uterine body insemination was 45.78%, the difference was very significant （P<0.01）. It indicated that deep uterine horn insemination could significantly improve the conception rate of Jilin mare during estrus, significantly reduce the number of effective sperms per insemination, and improve the utilization efficiency of male semen.
