ESR和FSH-β基因多态性对大白猪繁殖性能的影响
Influence of ESR and FSH-β Polymorphisms on Reproductive Traits of Yorkshire Sows
摘要
Abstract
To study the influence of the genotypes of estrogen receptor(ESR) and follicular-stimulating hormone beta subunit (FSH-β) on reproductive performance of Yorkshire sows,PCR and RLFP technique was used for genotyping and the genetic effects of genotypes on reproductive traits were analyzed.The results showed that B allele was predominant for both ESR and FSH-β gene.For both ESR and FSH-β gene,TNB,NBA and NHB of genetype BB were 0.06～1.14 higher than those AA in gilts(P＞0.05);In multiparous sows,for ESR gene the NBA and NHB of genotype AA were 0.12 and 0.07 higher than those of BB (P＞0.05);To FSH-β gene,TNB,NBA and NHB of BB genetype were 0.04～0.24 higher than those of AA(P＞0.05);Then combining genetype analyzed shown that ABAA of ESR-FSH-β in the first parity and BBAA of ESR-FSH-β in the later parities were the most prolific alleles.TNB,NBA and NHB of BBAA combined genetype were 2.03,1.75 and 1.65 higher than AAAA(P＜0.05).The present data revealed that ESR and FSH-β polymorphisms were associated with reproductive performance of Yorkshires.关键词
