Abstract:In order to study the effects of different weaning patterns on the growth and development of Gannan calving yaks,a univariate variance design was used in this experiment.A total of 90 calving yaks with similar body weight(11.34±1.62kg)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.The results show that:The growth and development of calving yaks with early weaning is better than the traditional feeding mode,which can effectively improve the growth performance of calves,and is an effective feeding mode that can be popularized.
