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.
