摘要: 利用内蒙古谢尔塔拉种牛场1977—2005年间1835头三河牛的育种记录,对305 d产奶量、外貌评分、体高、体斜长、胸围、管围、体重共7个性状进行遗传统计分析,并应用动物模型,借助约束最大似然法(REML)和DMU软件估计上述数量性状的参数。结果表明,305 d产奶量、外貌评分、体高、体斜长、胸围、管围、体重的遗传力分别为0.26、0.18、0.38、0.21、0.28、0.20、0.39;体重与体尺的遗传相关在0.51~0.72之间。

Abstract: Breeding data of 1835 individual Sanhe cattles recorded from 1977 to 2005 was collected at Breeding Centre of Inner Mongolia and used for genetic statistic analyses of milk yield (305 days), stature, body length, chest girth, shank circum and body weight. By using animal model, REML and DMU were utilized to estimate the genetic parameter. The results showed that the heritability of seven traits above was 0.26,0.18,0.38,0.21,0.28,0.20 and 0.39 respectively. The genetic correlation between body weight and body size was among 0.51 to 0.72.
