摘　　要：为探讨饲喂玉米秸秆、苜蓿干草、玉米青贮和羊草对泌乳期母羊、羔羊生产性能及节粮效果的影响。选取体重、体况、产期相近的泌乳期母羊及其羔羊各25只,随机分为5组,根据不同粗饲料种类设计不同的日粮组成,预饲期15 d,正试期41 d。结果表明,与"玉米秸秆(44.97%)+精料(55.03%)"组相比,"玉米秸秆(51.72%)+玉米青贮(5.17%)+苜蓿干草(5.17%)+精料(37.94%)"组母羊增重、羔羊增重、泌乳量分别提高1.94、1.81和0.13 kg,料重比为20.65:1,节省精料18.04 kg,总增收145.62元;"玉米秸秆(46.51%)+苜蓿干草(10.23%)+精料(43.26%)"组母羊增重、羔羊增重、泌乳量分别提高1.14、1.29和0.091 kg,料重比为27.50:1,节省精料12.30 kg,总增收100.72元;"羊草(58.87%)+苜蓿干草(8.16%)+精料(32.97%)"组母羊增重、羔羊增重、泌乳量分别提高0.86、1.11和0.084 kg,料重比为29.38:1,节省精料22.96 kg,总增收98.04元;"羊草(57.69%)+精料(42.31%)"组母羊增重、羔羊增重、泌乳量分别提高0.42、0.78和0.063 kg,料重比为37.27:1,节省精料13.53kg,总增收57.17元。In order to study the different combination of roughage on lactation ewe lamb production performance and economic benefit. The paper select 25 lambs and 25 ewes which were the same weight and body condition. They are divided into 5 groups randomly. According to the different kinds of the roughage, I design five diets. Experimental period was 41 days. Raise period in advance was 15 days. The results showed that comparing with the group which included corn stalk（44.97%） and concentrate feed（55.03%）, the ewe weight, lamb weight and lactation yield of the group which included corn stalk（51.72%）, corn silage（5.17%）, alfalfa hay（5.17%） and concentrate feed（37.94%） were increased by 1.94, 1.81 and 0.13 kg, the feed gain ratio is 20.65：1, it saved the concentrate feed by18.04 kg and the additional revenue was 145.62 yuan, respectively. The ewe weight, lamb weight,lactation yield of the group which included corn stalk（46.51%）, alfalfa hay（10.23%） and concentrate feed（43.26%） were increased by 1.14, 1.29 and 0.091 kg, the feed gain ratio is 27.50：1, it saved the concentrate feed by 12.30 kg and the additional revenue was 100.72 yuan, respectively. The ewe weight,lamb weight, lactation yield of the group which included Chinese wildrye（58.87%）, alfalfa hay（8.16%）and concentrate feed（32.97%） were increased by 0.86, 1.11 and 0.084 kg, the feed gain ratio is 29.38：1, it saved the concentrate feed by 22.96 kg and the additional revenue was 98.04 yuan, respectively. The ewe weight, lamb weight, lactation yield of the group which included Chinese wildrye（57.69%） and concentrate feed（42.31%） were increased by 0.42, 0.78 and 0.063 kg, the feed gain ratio is 37.27：1, it saved the concentrate feed by 13.53 kg and the additional revenue was 57.17 yuan, respectively.
