Study of the Effect of Different Dose and Different Volume on Fertility of Sows with Uterine Insemination and Standard AI
摘要
Abstract
To study the effect of different dose and different volume on fertility of sows, we chose uterine insemination and stand AI as the primary method. The oestrus sows were randomly divided into 2 groups, Group A for uterine insemination (n=60), another Group B for standard AI (n=60). Inseminating Group A sows and Group B sows with different insemination dose (3 billion spermatozoa/80 mL, 1.5 billion spermotozoa/80 mL, 1.5 billion spermotozoa/40 mL, n =20)respectively. The results showed that, compared with standard AI group,the pregnancy rate and the farrowing rate in uterine insemination group were 93.33% and 88.33% respectively, just a little higher than standard AI group. But uterine insemination group had a significant improvement in total number of piglet born and live-born litter size, up to 1.07 and 1.15. Wether Group A or Group B, compared with 3 billion spermatozoa/80 mL, using a dose of 1.5 billion spermotozoa with 80ml extender could obtain consistent effect on fertility of sows.This result could increase the utilization of boars by 1 time,and reduce the requirements of the insemination dose in <GB23238-2009> . It is recommended to expand the test and promote the use of uterine insemination.关键词
