摘　　要：[目的]为了测定在放牧条件下三河牛平均干物质采食量DMI,从而为调制三河牛饲料配方提供基础数据。[方法]以16头处于泌乳前中期健康成年三河牛为试验材料,以每头牛5个羊单位设计样地,测定夏秋季三河牛的放牧采食量。[结果]在呼伦贝尔草原以羊草为主的牧地上,三河牛放牧采食量为16.5 kg/d风干物质,变动范围为16.3～16.8 kg/d,组间差异不显著。[结论]该研究为三河牛夏秋季放牧采食量提供了参考。The experiment had the objective to determine the mean dry matter intake by Sanhe cattle under grazing environment, so as to provide basal data for the formulation of feed formula of Sanhe cattle. A total number of 16 healthy adult Sanhe cattle were used in the experiment, by providing 5 sheep units of plot for each Sanhe cattle to determine the grazing feed intake of the Sanhe cattle during summer and autumn. The result showed that under the environment of range in Hulunbeier, the feed intake of Sanhe cattle under grazing environment was 16.5 kg air-dried dry matter, with a range of 16.3-16.8 kg with no significant difference among the groups. This study provided reference for the grazing feed intake of Sanhe cattle during summer and autumn.
