摘要

摘要: 采用PCR-RFLP技术检测长白猪、大白猪以及长大杂种的ESR基因位点多态性,并分析ESR各基因型与繁殖性状的相关性。结果表明,3个猪群在该位点均存在多态性,A等位基因频率占有优势均在0.75以上,而B等位基因频率较低,均小于0.25。不同基因型与初产胎次、经产胎次母猪的各繁殖性状(总产仔数、产活仔数、初生窝重、断奶成活数)呈AAABBB趋势;与总体胎次母猪的繁殖性状(总产仔数、产活仔数、初生窝重)也呈AAABBB趋势;其中经产胎次及总体胎次的总产仔数基因型AA与AB之间差异显著(P0.05)。

Abstract: The polymorphism of ESR gene in Landrace,Large White and Landrace譒arge White was detected by using PCR-RFLP.The correlation between the genotypes of ESR gene and reproductive traits was analyzed.The result indicated that ESR locus existed polymorphism in the 3 swine populations.The allele frequency was higher than 0.75,and the B allele frequency lower than 0.25.The reproductive traits (Total Number Alive,or TNB;Number Born Alive,or NBA;Birth Weight,or BW;Number Born Weaning,or NBW) of the first and later parities were affected by various genotype.They tended to be AAABBB.In addition,the reproductive traits (TNB,NBA,and BW) of all parities were also affected by various genotype with the same trend,i.e.,AAABBB.The TNB of the later parity and all parities was significantly different between AA and AB genotype (P0.05).
