摘　　要：为了探讨鄂尔多斯细毛羊成年母羊四季放牧采食情况,实现鄂尔多斯细毛羊精准饲喂模式,采用饱和烷烃法对鄂尔多斯细毛羊成年母羊四季放牧采食量进行了测定。结果显示：鄂尔多斯细毛羊成年母羊春、夏、秋、冬四季放牧采食量分别为（2.24±0.15）kg、（3.32±0.23）kg、（1.60±0.21）kg、（0.93±0.14）kg;其中成年母羊以夏季采食量最高,显著高于（P〈0.05）春季和秋季,春、夏、秋3季均极显著高于冬季（P〈0.01）。提示：在放牧条件下,成年母羊应根据草场营养供给情况在冬季进行适当补饲。In order to explore the grazing intake of adult female sheep（ewes） of Ordos fine wool in each of the four seasons in a year,a saturated alkane method was adopted in the test. The results showed that the grazing intake of the ewes was 2. 69±0. 28 kg in spring,1. 67±0. 22 kg in summer,1. 70±0. 30 kg in autumn and 0. 85±0. 17 kg in winter,respectively. The sheep＇ s intake in spring is the highest of the four seasons,significantly higher（P〈0. 05） than that in summer and autumn; and their grazing intake in spring,summer and autumn are significantly higher in winter（P〈0. 01）. Under the condition of grazing,the mature ewes of Ordos fine wool should be supplemented with feedstuff in winter according to the scarce pasture and nutrition.
