不同断奶模式对甘南犊牦牛生长发育的影响

Effects of Different Weaning Patterns on Growth and Development of Gannan Yak

摘要:

为了研究不同断奶模式对甘南犊牦牛生长发育的影响,本试验采用单因素方差试验设计,共选取90头体重相近(11.34±1.62) kg犊牦牛作为试验对象,随机分为3组,自然放养组(对照组)、3月龄断奶组(试验1组)、6月龄断奶组(试验2组),每组30头,公母各半,试验周期7个月,在犊牛初生期、4月龄、7月龄分别进行体重、体高、体长、胸围指标进行测定。研究结果表明,采用早期断奶的犊牦牛生长发育状况优于传统饲养模式,有效提高了犊牛的生长性能,是一项可以推广的有效饲养模式。

Abstract:

In order to study the effects of different weaning patterns on the growth and development of Gannan calving yaks,a one-way anova variance design was used in this experiment.A total of 90 calving yaks with similar body weight(11.34±1.62) kg were selected as test subjects and randomly divided into 3 groups:natural range group(control group),3-month-old weaning group(experiment group 1) and 6-month-old weaning group(experiment group 2).Thirty calves were in each group,half male and half female.The experiment period was 6 months.Weight,height,length and chest circumference of calves were measured at birth,four months and seven months of age,respectively.The results show that:The growth and development of calving yaks with early weaning was better than the traditional feeding mode,which could effectively improve the growth performance of calves.It was an effective feeding mode that could be popularized.
