将9只体况良好、体重相近的成都麻羊半同胞羯羊，随机分成3组，饲以稻草基础日粮，分别补饲25%（MSL25）、50%（MSL50）与75%（MSL75）的苜蓿（MSL），采用单因子试验设计，研究稻草补饲苜蓿对山羊能量消化代谢的影响。结果：总能（GE）的消化率与代谢率自高到低的排序均为MSL75＞MSL50＞MSL25，其相应值分别为58.92%、54.48%与51.12%，48.42%、44.87%与41.85%，除MSL75与MSL25外（P<0.05），其余组间差异不显著（P＞0.05）。消化能（DE）转化为代谢能（ME）的效率自高到低排序为MSL50（82.36%）＞MSL75（82.18%）＞MSL25（81.86%），组间差异不显著（P＞0.05）。说明山羊稻草基础日粮补饲50%MSL的能量利用效率最佳，表现出明显的组合效应。

Nine healthy Chengdu Ma wether Goats from sire half-sib with similar age and weight were divided into three groups randomly and fed with the rice straw (RS) basic diets supplemented with 25%( MSL25), 50%( MSL50) and 75%(MSL75) alfalfa hay (Medicago sativa Linn, MSL) respectively for determining the digestion and metabolism of energy in trial goats. The results showed that the GE digestibility for the 3 mixed forages ranked from greatest to least in the following:MSL75 (58.92%)>MSL50 (54.48%)>MSL25 (51.12%), and the GE metabolism ranked in the same order as that of GE digestibility:MSL75 (48.42%)>MSL50 (44.87%)>MSL25 (41.85%), there was no signiifcant difference (P>0.05) between MSL50 and MSL75, MSL25 except for MSL25 and MSL75 (P<0.05) for both GE digestibility and its metabolism. The conversion efifciency of DE to ME for the 3 mixed forages ranked from greatest to least in the following:MSL50 (82.36%)>MSL75 (82.18%)>MSL25 (81.86%) (P>0.05). It was concluded that the associative effects on energy efifciency of goat fed RS supplemented with the 50%of MSL were apparent.
