民猪PRLR基因PCR-SSCP多态性与产仔数关联分析
The Association Analysis Between PRLR Gene PCR-SSCP Polymorphism and Litter Size in Min Pigs
摘要
Abstract
[Objective]The effect of polymorphism in PRLR gene on litter size in Min Pigs was studied.[Method]The polymorphism of PRLR gene was investgated by PCR-SSCP method and the effect of PRLR gene on litter size traits in Min Pigs was analyzed using the least square analysis.[Result]The results showed that the polymorphism in PRLR gene was found.B allele was the dominant allele.BB genotypic sow of Min Pigs produced 0.93 TNB and 0.78 NBA more than AA genotypic sow on the locus of PRLR-1 for the first parity, respectively (P＜0.05), 0.62 TNB and 0.74 NBA for later parities (P＜0.05).TNB and NBA had no significant difference among three kinds of genotype on the locus of PRLR-2 for both the first parity and later parities (P＞0.05).Min Pigs are in the situation of Hardy-Weinberg balance on both locus.[Conclusion]The effect of B allele of PRLR gene on litter size is significant.关键词
