| Abstract: | Reducing the number of pig sperm per dose,appropriately,can improve the utilization efficiency of boars,reduce the breeding scale of boars,and increase the use of high genetic value boars.In this experiment,the reproductive performance of multiparous sows,inseminated by 4 doses semen with deep insemination,experiment groups:1.2 billion/80 mL,1.2 billion/60 mL and 1 billion/60 mL doses,and 1.5 billion/80 mL dose as the control group,have compared.The results showed that:conception rate 1.5 billion/80 mL>1.2 billion/60 mL>1 billion/60 mL>1.2 billion/80 mL,no significant difference(P>0.05);farrowing rate 1.5 billion/80 mL>1.2 billion/60 mL>1.2 billion/80 mL>1 billion/60 mL,there was no significant difference(P>0.05);there was no significant difference in total pigs born per litter,pigs born alive per litter,and litter birth weight(P>0.05).In conclusion,compared with the control group,the 1.2 billion/60 ml dose group do not affect the reproductive performance,and increase the production capacity of pig sperm by 20%,which has promotion value. |
