摘要
[目的]研究TMR对犊牛早期生长发育的影响。[方法]选取12头健康的延边黄牛公犊,分为对照组(常规饲养)和试验组(TMR),分别在犊牛的2、3和4月龄进行体重和体尺的测量。[结果]TMR对犊牛各月龄体尺及体尺指数有提高的趋势,但影响不显著(P>0.05);而TMR提高了整个试验期犊牛的体重和月增重,并且在4月龄时影响达显著水平(P<0.05)。[结论]TMR比常规饲养更有利于犊牛早期生长发育。
[ Objective ] The effect of TMR on the calf growth and development in early growing period was studied. [ Method ] 12 healthy Yanbian calves were divided into the control group（ conventional feeding） and the experimental group（TMR）. The body weight and size of the calf with 2, 3 and 4 month-old were measured, respectively. [ Results ] The calf body size and its index in TMR were improved（P 〉 0.05 ） in each month-old＇s calf. And in TMR, the calf body weight and calf weight-gaining per month were enhanced in the entire trial period and there was a significant increment in 4 month-old＇ s calf （P 〈0.05）. [ Conclusion] TMR treatment to the calf growth and development in early period was more conducive than conventional treatment.
