Abstract Two experiments were conducted to assess the effect of lupin grain (Lupinus angustifolius; LUP) on milk characteristics of Awassi ewes, nutrient intake and digestibility and body weight of suckling lambs. Same diets were offered to the different groups of animals in both experiments. Dietary treatments contained no LUP (CON) or 200 g/kg LUP (LUP200) of dietary dry matter (DM) in substitution part of soybean meal and barley grain. Twenty-four Awassi ewes with initial body weight (BW) of 63.5 ± 2.19 kg were selected for the first experiment and randomly assigned to one of the two dietary treatments (12 ewes/diet). Nutrient intake was measured daily of the experiment. Body weight and milk yield were recorded on days 0, 14, 28 and 56 of the study. Twelve Awassi lambs (BW = 35.3 ± 0.75 kg) were used in the second experiment (6 lambs/diet) to assess the effect LUP addition on nutrient digestibility and N retention balance. In experiment 1, intake of acid detergent fiber was higher (P

加入甜羽扇豆 (Lupinus angustifolius) 可提高 Awassi 母羊的泌乳性能

摘要 进行了两个实验，以评估羽扇豆（Lupinus angustifolius；LUP）对Awassi 母羊的乳汁特性、营养摄入和消化率以及哺乳羔羊体重的影响。在两个实验中向不同组的动物提供相同的饮食。日粮处理不包含 LUP (CON) 或 200 g/kg LUP (LUP200) 的日粮干物质 (DM) 替代部分豆粕和大麦粒。第一次实验选择了 24 头初始体重 (BW) 为 63.5 ± 2.19 kg 的 Awassi 母羊，并随机分配到两种日粮处理之一（12 头母羊/日粮）。在实验中每天测量营养摄入。在研究的第 0、14、28 和 56 天记录体重和产奶量。十二只 Awassi 羔羊 (BW = 35.3 ± 0. 75 公斤）用于第二个实验（6 只羔羊/日粮）来评估 LUP 添加对养分消化率和 N 保留平衡的影响。实验1中酸性洗涤纤维的摄入量较高（P
