摘　　要：选用4周龄扬州鹅180只,以能量和蛋白质为试验因子,采用2因素3水平设计,研究日粮能量和蛋白质水平对生长期扬州鹅生产性能的影响。研究结果表明:①10周龄体重和日增重各组间差异不显著(P>0.05),屠宰指标间无明显规律。②对体重、日增重、屠宰率和腿肌率的影响,均是互作>能量>蛋白质,其中互作和能量对腿肌率的影响极显著(P<0.01);对半净膛率和全净膛率的影响,均是能量>互作>蛋白质,且影响均不显著(P>0.05);对胸肌率的影响,是能量>蛋白质>互作,且影响不显著(P>0.05)。③第7组(低能高蛋白组)在生长性能和经济效益方面均较佳。因此,推荐5￣10周龄仔鹅日粮能量、蛋白质水平分别为10.50MJ/kg、17%。A 2×3 factorial experiment was conducted with 180 28-day-old Yangzhou goslings to lnvestigate the effect of dietary metabolizable energy（ME）and crude protein（CP）levels on growth performance, which took ME and CP as the two factors.The results showed that： ①There were no significant difference amony groups in body parameters ;②The effects of weights of 10 weeks and daily gain,and no rules amony groups in slaughter ME,CP and interaction between them on body weights,daily gain, slaughterrate and leg muscle rate was interaction〉ME〉CP, and interaction and ME could significantly effect leg muscle rate（P〈0.01）; the effects of them on half carcass weight rate and eviscerated carcass weight rate was ME〉interaction〉CP, and all insignificantly（P〉0.05）; the effects of them on breast muscle rate was ME〉CP〉interaction;③The 7th group was good at growth performance and economicail benefit. So 10.50 MJ/kg and 17% were respectively recommended as ME and CP levels in 5-10 weeks goslings.
