[目的]目前牦牛生产仍然基本沿用传统的生产模式，生产管理仍是按照传统的低投入、低消耗、低产出、长周期、周转慢的粗放生产系统，牦牛业的生产效率仍然很低，由于牧民难以科学地和有规模地进行科学的饲养管理，早期由于人犊争奶、过度挤母乳，造成犊牛摄取营养不足，直接影响其生产性能的发挥。为了改变这一长期延用下来的生产模式，笔者就对牦牛犊进行全哺乳后的生长发育情况进行了试验研究。[方法]采用随机抽样法将60头初生犊牛分成2组，分别为试验组与对照组，[结果]表明6月龄时其体高、体斜长、胸围、管围、体重分别达到了79.74 cm、86.84 cm、100.10 cm、11.68 cm、64.87 kg。经数据统计分析差异均显著(P <0.05)。[结论]全哺乳组牦牛犊牛生长发育情况良好，是值得推广的饲养模式。

Objective]Currently the production mode of yak still belongs to the basic traditional produc-tion mode,and production management is still in accordance with the extensive production systems,which is characterized with low input,low output,low consumption,long cycle,slow turnover.Thus,yak in-dustry production efficiency is still very low since it's difficult for the herdsman to scientifically make breeding management and culture on a large scale.Moreover,in the past,many factors involving in com-peting for milk between human and calves,squeezing milk in excess,led to insufficient intake of nutrition for calves,then it directly affected the production performance.In order to change the production mode of the extended down for a long time,this paper studied the growth conditions of yak calves after all breast-feeding.[Method]A total of 60 new-born calves were divided into 2 groups using random sampling meth-od,named experimental group and the control group,respectively.[Results]The results showed that the parameters of body height,body length,chest circumference,pipe circumference,weight were 79.74 cm, 86.84 cm,100.10 cm,1 1.68 cm,64.87 kg,respectively,when they were 6 months old.[Conclusion]The data statistical analysis showed significantly difference (P < 0.05).
