【摘要】 应用半同胞相关法估计了鄂托克旗阿尔巴斯白绒山羊种羊场周岁羊产绒量和成年羊平均产绒量的遗传力和二者间的遗传相关 ,得到结果为 :①周岁产绒量遗传力为 0 4 4 ,属较高遗传力 ;②成年产绒量的遗传力为 0 2 6 ,属中等水平 ;③二者间遗传相关系数为 0 34,属中等偏高正向遗传相关。研究得出结论 :依据阿尔巴斯白绒山羊的周岁产绒量进行个体选择 ,可以达到提高羊群周岁产绒量的目的 ,而且也能够通过早期选种提高成年羊产绒量的目的。更多还原

【Abstract】 In this study,half sib correlation was used to estimate genetic parameter for 1 year cashmere yield(1 YCY)and average cashmere yield of adult goats(ACY)at Albas goats farm,Etuoke Banner,Inner Mongolia.The results were:(1)Heritability for 1 YCY was 0 44 which belonged to high level;(2) Heritability for ACY was 0 26 which belonged to middle level;(3) Genetic correlation between 1 YCY and ACY was 0 34 which belonged to high positive correlation.Studying made conclusions which individual selection according to 1 YCY of Albas white cashmere goats could improve 1 YCY and also ameliorate ACY by early selection.更多还原
