| Abstract: | In order to determine the improving effects of beef Simmental on Yunnan local yellow cattle, the body weight and body sizes of crossbred progeny of beef Simmental and Yunnan local yellow cattle. The results showed that of the body weight and body sizes of crossbred progeny were significantly higher than that of Yunnan local yellow cattle(P<0.01). The body weight of crossbred progeny at birth, 6 months, 12 months,18months, 24 months were higher than that of Yunnan local yellow cattle by 82%, 18%, 69%, 50% and 78%, respectively. |
