摘　　要：为了探讨乌珠穆沁后备母羊四季放牧采食情况,试验采用饱和链烷烃法对乌珠穆沁后备母羊四季放牧采食量进行测定。结果表明:乌珠穆沁后备母羊春、夏、秋、冬四季放牧干物质采食量分别为(1.68±0.11)kg、(3.22±0.19)kg、(0.95±0.27)kg和(0.52±0.07)kg,以夏季采食量最高,显著高于春季(P<0.05),极显著高于秋季和冬季(P<0.01);春季和夏季蛋白质摄入量均高于需求量,秋季和冬季均低于需求量。说明在放牧条件下,乌珠穆沁后备母羊在秋季和冬季应根据草场营养供给情况进行有效补饲。In order to explore the feed intake of backup ewe of WuZhu MuQin sheep under the condition of grazing seasons,the grazing feed intake was measured by the saturated alkane method. The results showed that the feed intake of backup ewe of WuZhu MuQin sheep in different seasons were（ 1. 68 ± 0. 11） kg,（ 3. 22 ± 0. 19） kg,（ 0. 95 ± 0. 27） kg and（ 0. 52 ± 0. 07） kg. The feed intake in summer was the highest which was higher than that in spring（ P 〈 0. 05） and significantly higher than that in autumn and winter（ P 〈 0. 01）. The results indicated that under the grazing condition,backup ewe of WuZhu MuQin sheep should be supplementary fed in autumn and winter according to the situation of pasture and nutrition.
