摘　　要：高温高湿条件下,48只断奶新西兰肉兔随机分为4组,每组12个重复,每个重复1只。研究非淀粉多糖酶对其生长性能、养分消化率的影响。对照组为基础日粮组,试验Ⅰ、Ⅱ、Ⅲ组分别在基础日粮基础上添加0.01%、0.02%、0.03%非淀粉多糖酶。结果表明,试验Ⅱ、Ⅲ组肉兔净增重和日增重明显高于对照组和试验Ⅰ组(P<0.05),饲料效率得到显著改善(P<0.05);试验Ⅱ、Ⅲ组能量、粗纤维、中性洗涤纤维和磷的养分消化率显著高于对照组(P<0.05)。综合考虑,肉兔日粮非淀粉多糖酶适宜添加水平为0.02%。Forty eight new Zealand rabbits at age of 35 d were randomly divided into 4 groups with 12 replicates of each,to study the effect of non-starch polysaccharide enzyme on performance and nutrient digestibility under hydrothermal condition.The control group was fed basal diet,and group Ⅰ , Ⅱ, Ⅲ were fed with basal diet added with 0.01% ,0.02 %, 0.03 % non-starch polysaccharide enzyme,respectively.The result showed that：net gain, daily gain and feed efficiency of group Ⅱ , Ⅲ were significantly higher than those of the control group and group Ⅰ （P 〈 0.05） ;gross energy（GE） ,crude fibre（CF）, neutral detergent fibre（NDF）and phosphorus digestibility of group Ⅱ , Ⅲ were significantly higher than those of the control group（P 〈 0.05）.It suggested that the optimum adding levels of non-starch polysaccharide enzyme was 0.02 %.
