摘　　要：丰草季人工草地划区轮牧条件下 ,考尔木 (Cormo)成年母羊群体采食量与怀孕日龄间呈显著正相关 ,回归方程Y =0 .0 0 2 6X +0 .642 2 ,相关系数r =0 .812 3,受孕前采食量0 .64kg/羊,产羔前采食量 1.0 3kg/羊 ,平均采食量 0 .Using rotational grazing during the pasture growth season, the intake of Cormo ewes increases with pregnancy term, equation Y=0.002 6X+0.642 2,r =0.812 3. Ewe intake was 0.64 kg/ewe/d before mating and 1.03 kg/d before lambing, 0.84 kg/ewe/d on average.
