摘　　要：为合理利用荒漠草原区饲草资源,本研究分别以华北驼绒藜(Ceratoides arborescens)和紫花苜蓿(Medicagosativa)为主要饲草,配合谷草(Setavia italica)、冰草(Agropyron cristatum)饲喂苏尼特羔羊,根据组合效应原理科学组合为6组:100%驼绒藜、50%驼绒藜+50%谷草、50%驼绒藜+50%冰草、100%苜蓿、50%苜蓿+50%谷草和50%苜蓿+50%冰草。结果表明,100%苜蓿饲喂的羔羊增重、屠宰率和净肉率都明显高于其它处理,饲喂效果最好。不同组合饲喂效果为:50%驼绒藜+50%谷草>100%驼绒藜、50%驼绒藜+50%冰草;100%苜蓿>50%苜蓿+50%谷草、50%苜蓿+50%冰草。For the rational use of desert steppe forages, studies were made on taken ceratoides and alfalfa as the main forage mached with aspartate and agropyron to fed sunit lamb. According to the principle of for- age combination, six treatments were formed. They were 100% ceratoides, 50% ceratoides-50% aspar- tate, 50% ceratoides-50% agropyron, 100% alfalfa, 50% alfalfa＋50% aspartate, 50% alfalfa＋50% agropyron. The results showed that lamb fed with 100% alfalfa had best growth and slaughter perform- ance. The feeding effect of 50% ceratoides%50% aspartate was better than 100% ceratoides, and 50% ceratoides＋50 % agropyron.
