| 摘 要： | 为探讨深部输精对母猪繁殖性能的影响，本试验以339 头经产大白母猪为研究对象，采用深部输精和常规输精为主要配种方式。比较分析季节、输精量、公猪精子种类、冻精及母猪同期发情等条件对猪群深部输精效率的影响，探寻在配种方面最佳的精液使用量、输精条件和精液种类。结果表明：夏季和冬季子宫深部输精组的产仔数、产活仔数和产健仔数均高出常规输精组。深部输精量为40 mL时各指标最好。输入同等量的精子，常规输精组的产仔数及活仔数均显著低于深部输精组。不同种猪精液各方面差异不显著。鲜精同期发情组在受胎率、产仔数、产活仔数均高于鲜精和冻精未同期发情组；后两者在产仔数量、产活仔数量和弱仔数量方面差异不显著。综上，深部输精技术在一定程度上能够提高母猪繁殖性能，增加猪场经济效益。

Deep Intra-uterine Insemination Affecting Sow Reproductive Performance |
| |
| Abstract: | To explore the effects of deep intra-uterine insemination (DUI) on sow productive performance, 339 multiparous Large White sows were used as research objects. Intra-uterine insemination (IUI) and DUI were used as the main mating manners. The effects of season, semen volume, semen type, frozen semen and sow synchronous estrus on the efficiency of DUI were compared and analyzed for the optimization of semen volume, insemination condition and semen type in the process of mating. The results showed that litter size, and numbers of alive and healthy piglets in DUI treatment were higher than those in IUI treatment both in summer and winter. The indicators were the best when 40 mL semen was used for DUI. When the same amount of semen was inseminated, litter size and number of alive piglets in IUI treatment were significantly lower than those in DUI treatment. However, different semen types did not show significant differences in all the indicators. Pregnancy rate, litter size and number of alive piglets in the treatment of estrus synchronization with fresh semen insemination were significantly higher than those of estrous non-synchronization with fresh or
frozen semen insemination. Moreover, litter size, and numbers of alive and weaker piglets were not significantly different in the latter two treatments. In conclusion, DUI can improve sow reproductive performance and increase economic benefits of pig farms to some extent. |
