【摘要】 对中国美利奴高山型超细型细毛羊群体的Hb、Tf、Alb、Es等血液蛋白位点多态性进行检测,对存在多态性的位点与细毛羊经济性状进行了相关分析。结果表明:中国美利奴高山型超细群体血红蛋白、血浆酯酶位点的不同表现型与体侧毛长、羊毛伸度、羊毛细度及剪毛量等存在显著相关;部分位点可为中国美利奴高山型超细品系培育的早期选种提供辅助依据。更多还原

【Abstract】 Ultra-fine wool sheep on the alpine area were used to study the polymorphism of blood protein Hb, Tf, Es and Alb, by means of polyacrylamide gel electrophoresis (PAGE). Correlation analysis of polymorphicloci to economic traits have been done. The results indicated that different penotypes of Hb and Es were significantly correlated with wool length of bodyside, wool extensibility, wool diameter and shearing yield (P<0.05). There for, some of the loci may be used as assistant markers of early selection for Chinese Merino ultra-fine wool sheep.更多还原
