摘　　要：选用20头年龄相近,体况良好的成年雄性林麝。采用完全随机设计分为4组,研究日粮添加过瘤胃脂肪(0,5,10,15 g/d)对林麝体重和日粮表观消化率的影响。结果表明:日粮添加不同水平过瘤胃脂肪对林麝体重无显著影响(P>0.05)。对林麝日粮粗蛋白、有机物、中性洗涤纤维、酸性洗涤纤维、钙、磷和干物质的表观消化率没有显著影响(P>0.05);10 g/d组日粮粗脂肪和能量的表观消化率较对照组显著提高(P<0.05),但与5 g/d组和15 g/d组差异不显著(P>0.05)。结果显示,林麝日粮过瘤胃脂肪的适宜添加水平为10 g/d。Twenty adult male Forest musk deer were randomly divided into four groups to evaluate the effects of supplementation of rumen protected fat at inclusion levels of 0, 5, 10 and 15 g/d on body weight and apparent digestibility of the animal. The results showed that there was no significant effect on body weight of Forest musk deer among treatments （P〉 0. 05）. The crude protein, organic material, neutral detergent fiber, acid detergent fiber, calcium, phosphorus and dry matter of diet were no significant difference among treatments （P〉0. 05 ）. The nutrient apparent digestibility of crude fat and energy of 10 g/d group were significantly higher than those of control group （P 〈 0. 05）. According to the experimental results, the optimum level of rumen protected fat in diet of Forest musk deer was 10 g/d.
