| Abstract: | To study the influence of estrogen receptor (ESR), osteopontin (OPN) and retinol binding proteins 4 (RBP4) genotypes on reproductive performance of Yorkshire sows, PCR-RLFP technique was used for genotyping, and the effects of genotypes on reproductive traits were analyzed. The results showed that A allele of ESR and OPN genes were predominant allele, and B allele of RBP4 gene was predominant allele. TNB,NBA of ESR gene AB and BB genotypes were higher than AA genotype;TNB of OPN gene AA genotype was the highest, but the NBA, NHB and WB for OPN gene genotypes were BB > AA > AB;The TNB,NBA,NHB and WB for RBP4 gene genotypes were AA > BB > AB. Then combing genotype analysis showed that ABAA of ESR-RBP4 and BBAA of OPN-RBP4 were the most prolific alleles, respectively. The present data revealed that ESR, OPN and RBP4 genes polymorphisms were associated with reproductive performance of Yorkshire sows. |
