不同输精方式和不同精液类型对母猪繁殖性能的影响
Effect of Different Insemination Method and Semen Types on Pig Reproductive Efficieney
摘要
Abstract
To study the effect of different types of semen (fresh semen and frozen semen) on fertility of sows with uterine insemination and standard AI.We used fresh semen and frozen semen to do uterine insemination and standard AI,respectively.Moreover,we also analyzed the effect of frozen semen on fertility of sows by different doses.The results showed that fresh semen can significantly improve the farrowing rate with uterine insemination.Meanwhile,we found that total number of born(12.71±2.84),born alive litter size(11.54±3.02),number of healthy birth(11.17±2.73) and birth weight(1.65±0.29) with uterine insemination was higher than standard AI (P＜0.05).Comparison between frozen semen and fresh semen showed that using frozen semen reduced the pregnancy rate 41.38％ and farrowing rate 41.38％ (P＜0.05),but other reproduction traits had no significant differences (P＞0.05).Moreover,increasing frozen semen dose significantly improved fertility of sows.In conclusion,combining frozen semen technique with uterine insemination can significantly improve the efficiency of pig production.关键词
