Comparison Test and Analysis on the Production Effects between Natural Mating and Artificial Insemination in Sow

[Objective]The aim of the research was to discuss the practicality of swine artificial insemination technology.[Method]The production indexes such as sow estrus pregnancy rate,the delivery rate of conceived sows and the average number of live piglets per litter were determined and the production effects of 2 kinds of mating ways of natural mating and artificial insemination were compared.[Result]For 323 sows mated by artificial insemination,the sow estrus pregnancy rate was 84.2%,the delivery rate of conceived sows was 90.8% and the average number of live piglets per litter was 10.3 heads.For 156 sows mated by natural mating in control group,the sow estrus pregnancy rate was 82.7%,the delivery rate of conceived sows was 91.0% and the average number of live piglets per litter was 10.2 heads.The production effects of 2 kinds of mating ways had no obvious difference.[Conclusion]The production level of artificial insemination technology has been reached or exceeded the level of natural mating in pig farms.
