【摘要】：本文旨在研究杜洛克和长白公猪精液稀释后精子活力和畸形率的动态变化。实验选取杜洛克和长白公猪各20头,采集新鲜精液并使用BTS稀释液进行常规稀释,检测稀释后0~96 h 9个时间点精液精子活力和畸形率。结果表明:猪精液稀释0 h精子活力最高,随后逐渐降低,2个品种猪精液稀释72 h后,精子活力出现快速下降,精子畸形率显著升高(P0.05),杜洛克公猪精液稀释后72 h畸形率(11.1%)、84 h畸形率(13.1%)显著高于长白猪(10.6%、11.8%)(P0.05),这可能暗示长白猪精液的适宜保存时间要长于杜洛克,但考虑繁殖性能方面,两品种猪精液稀释后保存时间不应超过72 h为宜。
[Abstract]:This paper aims to study the dynamic changes of Duroc and Landrace boar semen diluted sperm motility and deformity rate. The experiment selected 20 Duroc and Landrace boars head, collecting fresh semen and use BTS dilution by conventional dilution, dilution of 0~96 h detection in 9 time points of semen sperm motility and deformity rate. The results showed that pig semen dilution 0 h sperm activity is the highest, then gradually decreased, 2 varieties of pig semen dilution after 72 h, sperm viability declined rapidly, significantly increased the rate of sperm deformity (P0.05), Duroc boar semen diluted 72 h abnormality rate (11.1%), 84 (13.1%) H malformation rate was significantly higher than Landrace (10.6%, 11.8%) (P0.05), which may be suitable for preservation time is longer than that of Landrace semen Duroc, but considering the reproductive performance, two varieties of pig semen dilution after the preservation time should not exceed 72 h as appropriate.

【正文快照】： 随着猪精液液态保存技术的发展,猪人工授精技术在养猪生产中广泛应用[1]。常温液态精液保存(17~25℃)与低温(0~5℃)和冷冻(-79~-190℃)保存方式相比,可以提高母猪受胎率和窝产仔数,有利于良种公猪遗传资源的利用[2],具有费用低和操作程序简单等优点[3]。猪精液常温保存的国
