| 摘 要： | 本试验研究了不同气候条件对早期断奶犊牛生长发育的影响。结果表明，不同气候对犊牛的生长发育有一定的影响，但犊牛开食料等饲养管理达到犊牛所需的标准，不会影响犊牛的生长发育指标，３个月龄时体重均能达ＮＲＣ饲养标准。在整个试验期呼市地区早期断奶犊牛平均增重为６４．０５ｋｇ，日增重为７０３．８５ｇ，而锡盟东乌旗犊牛平均增重为５７．５０ｋｇ，日增重为６３１．８７ｇ。体高、体长、胸围、十字部高等体尺指标呼市地区犊牛均高于锡盟东乌旗犊牛，而腹围呼市地区略低于锡盟东乌旗犊牛。干物质的进食量，气候条件差的地区有高于相对暖和地区犊牛的趋势。

| Abstract: | The influences of different climatic conditions on the growth
and develop-ment of early weanng calves have been studied.The results showed that in the
case of ade-quate feeding and managements,climatic conditions only have a little influence on
earlyweaning calves,but not significant,all caives can attained the standard weight required
byNRC,when they were three months old.In whole experimental period,the mean daily weigyt
gain of the early weaning caives inHuhehaote was 703,85g/d,total weight gain was 64. 05kg,the
correspondent figure were631. 87g/d and 57.50Kg in eastern Xilinguole respeetively. Also,the
calves in Huhehaotewere superior to that in eastern Xilinguole.in height at withers,body length.
heart girth andheight at hip cross except for belly circumference, The result,shows that calves
in rough cli-mates could eat more dry matter than those in mild climates. |
