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.
