摘　　要：该试验选择不同初生重大小的西门塔尔牛犊牛18头,根据体重的大小随机分为两组,分别是小初生重组(体重<40 kg),大初生重组(体重>45 kg)。结果表明:大初生重组犊牛和小初生重组犊牛的后期体重、体高、十字部高、胸围等指标均无显著差异(P>0.05)。可见,即使犊牛的初生重较小,但是通过合理的饲养管理,在后期的生长发育也能达到初生重大犊牛的生长发育水平。In this experiment,18 Simmental calves with different birth weights were selected and randomly divided into two groups according to their body weights,namely small birth recombination(body weight<40 kg)and large birth recombination(body weight>45 kg).The results showed that there was no significant difference(P>0.05)in late body weight,body height,cross sec-tion height and chest circumference between the large primiparous recombined calves and the small primiparous recombined calves.It can be seen that even if the calf's newborn weight is small,but through reasonable feeding management,the growth and develop-ment in the later period can reach the growth and development level of the newborn major calves.
