The present invention provides a set of molecular markers related to pig total litter size traits and their combined application, wherein the molecular marker combination includes SNP sites at rs318687930, rs346259996 and rs332860516. By detecting the genotypes of pigs rs318687930, rs346259996 and rs332860516, the total litter size of pigs can be predicted according to the genotype, which is beneficial to improve the selection efficiency of excellent sows and speed up the breeding process of pigs with high total litter size. |
