摘　　要：[目的]为了观测不同能量水平的精料对杂交水牛犊牛生长性能的影响。[方法]本试验选用15头3~5月龄的健康杂交水牛犊牛,随机分为三组,分别综合净能（Nemf）为6.0、6.7、7.4MJ/Kg的精料,进行31d的育肥试验。[结果]表明,总体来说,三组犊牛组间试验前后在平均粗料DM采食量、平均日增重、胸围指数、体长指数、体躯指数、管围指数方面均无显著性变化（P〉0.05）。[结论]说明在相同饲养条件下,饲喂综合净能为6.0 MJ/kg的精料即可满足3~5月龄杂交水牛犊牛生长发育的能量。【Objective】In order to observe the different energy levels of fine material impact on the growth performance of hybrid buffalo calf.【Method】15 3-5months hybrid buffalo calves were selected and divided into three groups randomly,respectively fed comprehensive net for 6.0,6.7,7.4 MJ/Kg of grain feed,conduct 31 dof fattening.【Result】The result showed that an average roughage DM intake,average daily gain,bust index,body length index,the body index,pipe circumference indices showed no significant change（P〉 0.05）among the three groups before and after the test calves overall.【Conclusion】Indicating that under the same feeding conditions,feeding consolidated net energy of 6.0MJ/Kg of concentrate to meet 3-5months hybrid buffalo calf growth energy.
