Association Analysis on Polymorphisms of Prolactin Receptor (PRLR) Gene Exon 10 with Reproductive Traits in Songliao Black Pig and Landrace Pig
摘要
Abstract
The purpose was to investigate the association between the polymorphisms of PRLR gene exon 10 and reproductive traits in Songliao Black pig and Landrace pig. Polymorphisms of PRLR gene exon 10 were detected by PCR-RFLP in Songliao Black pig and Landrace pig, then their genetic effects on reproductive traits were analyzed by the least square method. The results showed that there were two alleles (A and B) and three genotypes (AA, AB and BB) in the two pig species, and the frequencies of the dominant allele A were 0. 551 and 0. 578 in Songliao Black pig and Landrace pig respectively. The weaning piglets number, the number of nipples of individuals with AA genotype were significantly higher than the other two genotypes (P<0. 05). The TNB and NBA of individuals with AA genotype in primiparous Songliao Black pig were significantly higher than other genotypes (P<0. 05) , other reproductive traits were not significantly affected by genotype, but showed the genotype AA>AB>BB trend.关键词
