Association Analysis on Polymorphism of the RBP4 Gene with Reproductive Performance in Yorkshire, Landrace and Duroc Pigs
摘要
Abstract
The polymorphisms of Msp Ⅰ site at exton 4 of RBP4 gene in Yorkshire, Landrace and Duroc populations were detected with PCR-RFLP method, meanwhile the total number born (TNB) , number born alive (NBA) , number of alive weaning litter (NW) , body weight of litter (BWL) , weaning weight of litter (WWL) and weaning survive rate of different genotypes for the 2nd and 3rd parity were measured, and then the relationship between reproductive performance and different genotypes was analyzed in this study. The results showed that the polymorphic sites of RBPA genes were found in all three breeds, the results of x2 test indicated that this site of Yorkshire didn't fit Hardy-Weinberg equilibrium(P<0. 05) , while this site of Landrace and Duroc fitted Hardy-Weinberg equilibrium (P>0. 05) . In addition, the dominant genotype in Yorkshire was AA genotype,however in Landrace and Duroc were BB genotype. For the reproductive performance, BB genotype of Landrace in 2nd parity produced 0. 97 TNB, 1. 28 NBA, 0. 92 NW, 1. 74 kg BWL and 4. 42 kg WWL more than AA genotype, and produced 0. 92 TNB, 1. 02 NBA, 0. 98 NW, 1. 43 kg BWL and 4. 98 kg WWL more than AA genotype. On the whole, BB genotype was also favourable genotype in 3rd parity.关键词
