候选基因多态性与肉鸡生长,采食量和饲料转比率的关联分析
发布时间:2021-11-03 03:54
鸟类的生长、采食量与饲料转化率受多种遗传因素的影响。本研究在9个与体重(BW)、体增重(BWG)、采食量(FI)和饲料转化率(FCR)相关的候选基因(LEPR,PRKAB1,PRKAG2, PRKAG3,MTOR,PDPK1,NPY6R,INS与GH1)中选取了49个SNP,对来自两个品系(N202和N301)的共796只已知系谱的雄性黄羽肉鸡进行基因型检测,其中22个SNP通过了基因型质量控制。另外,本试验分别测量了个体的49日龄(BW49)和70日龄(BW70)的体重,以及49至70日龄之间的采食量。体增重和饲料转化率通过49至70日龄之间的体重与采食量计算得出。SNP位点与表型性状的关联分析结果如下:1.对于LEPR,结果表明rs14657368与两个品系中的体增重和饲料转化率都存在显著相关(P<0.05),rs13684613和rs14657336与两品系中的采食量均存在显著相关(P<0.05)。两品系中显著相关表现出的一致性,证实了这一结果。虽然rs13684616与两品系的采食量均存在相关(P<0.05),但是却具有相反的基因效应。而某些SNP-性状关联只...
