摘　　要：本研究旨在提高不同蛋白水平对杜泊羊和澳洲白羊的生产性能影响。本试验随机选取初始条件相近杜泊羊247只、澳洲白羊305只,随机分为高蛋白组(蛋白水平14.28%,代谢能水平13.03 MJ/kg)、能量蛋白均衡组(蛋白水平11.78%,代谢能水平13 MJ/kg)和高能量组(蛋白水平10.15%,代谢能水平12.86 MJ/kg),每组设计3个处理。用SPSS进行单因素方差分析。结果表明:高蛋白组绵羊平均日增重(ADG)最高,高蛋白组配方(蛋白水平14.28%,代谢能水平13.03 MJ/kg)影响显著。The purpose of this study was to improve the effects of different protein levels on the performance of Dorper sheep and Australian white sheep.In this experiment,247 Dorper sheep and 305 Australian white sheep with similar initial conditions were randomly selected and randomly divided into high protein group(protein level was 14.28%,metabolizable energy level was 13.03 MJ/kg)and the energy-protein balanced group(protein level was 11.78%,the metabolizable energy level was 13 MJ/kg)and the high-energy group(protein level was 10.15%,metabolizable energy level was 12.86 MJ/kg),and three treatments were designed in each group.One-way ANOVA was performed with SPSS.The results showed that:The high protein group had the highest average daily gain(ADG),and the formula of the high protein group(protein level was 14.28%, metabolizable energy level was 1.93 MJ/kg)had a significant effect.
