Abstract: In order to explore the effect of OLR1 gene genetic polymorphism on litter size of Xidu black pigs, the direct sequencing method was used to detect the genetic polymorphism of OLR1 gene in the Xidu black pigs, and the association analysis with litter size was carried out. The results showed that there was a T/C mutation at 7 bp of intron 4, and there were three genotypes TT, TC and CC; The total number born and number born alive of individuals with TT genotype were extremely significantly higher than those with TC and CC genotype (P<0.01), indicating that the mutation had a significant impact on litter size traits of Xidu black pig.

Key words: OLR1 gene, Xidu black pig, litter size, association analysis
