【摘要】 通过PCR-RFLP研究UCP3基因在岔路黑猪(56头)、皮岔猪(皮特兰×岔路黑猪10头)、嘉兴黑猪(50头)群体中的基因和基因型频率分布,测定21头纯种岔路黑猪的胴体和肉质性状,并利用一般线性模型分析UCP3基因型与以上性状的相关性。结果发现该基因对岔路猪胴体长、前背膘厚、后背膘厚、三点平均背膘厚有显著影响,且对岔路猪肉质性状中的L值、腿肌pH值、眼肌温度、眼肌导电率影响显著。更多还原

【Abstract】 The allele and genotype frequencies of uncoupling protein 3 gene(UCP3) in Chalu black pig (56),Jiaxing black pig(50) and Pietrain×Chalu black pig(10) were detected by PCR-RFLP method.The carcass and meat quality traits in 21 pure Chalu Black pigs were measured.Then the relationship between the genotypes of UCP3 and the traits above was analyzed using the general linear model.The results showed that UCP3 gene had significant effects on the carcass length、shoulder back fat thickness、waist-straw combining back fat thickness and average back fat thickness,and also the L value、pH of leg muscle,eye temperature and eye conductivity.更多还原
