定时输精技术对杜洛克母猪繁殖性能的影响

Effect of timed artificial insemination technology on reproductive performance of Duroc sow

摘要: 本文旨在探索定时输精技术对杜洛克母猪繁殖性能的影响。在温氏种猪公司华东某猪场，对杜洛克正常发情后备母猪、无情期后备母猪及断奶母猪使用定时输精技术后，测定其繁殖性能。试验结果表明采用定时输精技术，可以一定程度上提高正常发情后备母猪以及断奶母猪的发情率、配种率、参繁受胎率、参繁分娩率以及繁殖效率，同时对无情期后备母猪也有一定的促进作用，可使其达到4.06头的繁殖效率。定时输精技术可以在一定程度上提高杜洛克母猪的繁殖性能。

Abstract: This paper was aimed to study the effect of timed artificial insemination technology on the reproductive performance of Duroc sows. Reproductive performances of normal estrus gilts, anestrus gilts and weaned sows were determined after using timed artificial insemination technology in a pig farm managed by Guangdong Wens Foodstuffs Group Co., Ltd in East China. The results showed that the estrus rate, fertilization rate, pregnancy rate, reproductive rate and reproductive efficiency of normal estrus gilts and weaned sows was significantly higher than the control group. The timed artificial insemination technology had a certain promoting effect on the reproductive efficiency of anestrus gilts, reaching 4.06 pigs per sow. The timed artificial insemination technology can improve the reproductive performance of Duroc sows to a certain extent.
