断乳牦牛犊的育肥试验及其生长发育情况的研究

Study on Feeding Fattening,Growth and Development of Yak Weaned Calves

[目的]为了探索在育肥条件下高寒牧区牦牛犊的生长发育情况，促使牦牛犊商品化，实施牦牛高效饲养技术与适时出栏技术相结合，改变本地区传统饲养模式，促进牦牛业向效益型畜牧业转变，为今后普及牦牛犊舍饲育肥，提供可靠数据和标准化饲养管理技术。[方法]于2012年12月-2013年5月，在贵南县开展了断乳牦牛犊舍饲育肥及生长发育效果观测试验。[结果]显示育肥牦牛犊的体高、体斜长、胸围、管围、体重分别达到了86．19cm、94．07cm、113．50cm、12．10cm、91．63kg与对照组相比差异均显著（P〈0．05）。[结论]对断乳牦牛犊进行舍饲育肥是牧区加快牦牛出栏、调整牛群结构、增加牧民收入的好方法。

[Objective]The aim of this study was to explore the growth and development of yak calves in the alpine Pasture and fattening conditions, as well as to lift the commercialization of yak calves. Also, corn bining with feed techniques and efficient implementation of yak timely slaughter technology, the another aim was to change traditional farming patterns in this region,as well as to promote the efficiency of the yak industry, which would provide reliable data for management and standardization of breeding technologies. [Method]The fitting experiment of yak calves was conducted in Guinan County from December 2012 to May2013. The conditions and data of feeding and growth fattening effect were recorded. [Result]The re sults showed that fattening body height, body length,chest tube circumference, body weight of yak calves reached 86.19 cm,94.07 cm,113.50 cm,12.10 cm,91.63 kg,which were significantly different when corn pared with the control group （P〈0.05）. [Conclusion]Yak calf weaning feeding fattening was a feasible measure to accelerate yak slaughter,adjust herd structure and increase the income of herdsmen.
