摘　　要：本文旨在研究不同能量水平小麦日粮中添加复合非淀粉多糖(NSP)酶制剂对肉鸡生产性能的影响。选用1 500只1日龄艾维茵肉鸡,随机分为5组,每组3个重复,每个重复100只雏鸡。5个处理分别为:玉米组(Ⅰ)、小麦组(Ⅱ)、低能小麦组(Ⅲ)、小麦+0.1%复合NSP酶制剂组(Ⅳ)和低能小麦+0.1%复合NSP酶制剂组(Ⅴ)。结果显示:与Ⅱ组和Ⅲ组相比,Ⅳ组和Ⅴ组F/G分别降低8.95%(P<0.05)和9.33%(P<0.05);蛋白质表观消化率显著提高(P<0.05);血清TG、VLDL(21 d)显著提高(P<0.05);血清T3水平显著增加(P<0.05);Ⅳ组与Ⅱ组相比,21 d和49 d血清胰岛素水平显著提高(P<0.05),Ⅴ组与Ⅲ组相比,35 d和49 d血清胰岛素水平也显著提高(P<0.05)。结果表明,在小麦日粮中添加NSP酶制剂可改善肉鸡生长性能。To study the effects of non-starch polysaccharides enzyme preparation added in wheat-based diet on productive performance of broiler,one thousand and five hundred Avian chickens were randomly divided into five groups, each with three replications of one hundred. The control group was fed maize-based diet （Ⅰ） with normal ME, the four experiment groups fed wheat-based diet of, （Ⅱ） normal ME, （Ⅲ） low ME, （Ⅳ） normal ME plus 0.1% enzyme preparation and （Ⅴ） low ME plus 0. 1% enzyme preparation, respectively. The results showed that, compared with group Ⅱ and group Ⅲ, F/G of group IV and group V decreased significantly by 8.95% and 9.33% （P〈0.05）, respectively. The apparent protein digestibility increased significantly （P〈0.05）. The concentration of TG and VLDL in serum at 21 d and the concentration of T3 in serum increased significantly （P〈0.05）. Compared with group Ⅱ , the concentration of insulin in serum of group IV increased significantly （P〈0. 05） at 21 d and 49 d, and compared with group Ⅲ , that of group V increased significantly （P〈0.05） at 35 d and 49 d. The results suggest productive performance of broiler can be improved by non-starch polysaccharides enzyme preparation added in wheat-based diet.
