摘　　要：本试验旨在研究非淀粉多糖复合酶制剂对肉鸡生产性能、养分表观利用率的影响。试验采用单因子随机分组试验设计,选取科宝肉鸡商品代1日龄公雏320只,随机分成2个处理组,各处理组8个重复,每个重复20只。处理1饲喂基础饲粮,处理2饲喂基础饲粮+150 g/t NSP复合酶制剂F。1-21 d基础饲粮采用玉米-豆粕型饲粮,22-42 d基础饲粮采用玉米-豆粕-杂粕型饲粮,低温制粒。结果表明,在1-21 d肉鸡的玉米-豆粕型饲粮中添加NSP酶制剂F对肉鸡生产性能和养分表观利用率无改善作用,而在高杂粕(3%菜粕、3%棉粕和8%DDGS)的玉米-豆粕-杂粕型肉鸡饲粮中添加NSP复合酶制剂F对22-42 d和1-42 d肉鸡生产性能均有改善作用,在一定程度上改善了22-42 d肉鸡饲粮的养分表观利用率。The objective of the present study was to investigate the effects of a non-starch enzyme preparation on the production performance and the nutrient apparent utilization of broilers. A single factorial experiment with a randomized design was adopted. Three hundred and twenty 1-day-old Cuba male broilers were randomly assigned to 2 treatments based on body weight with 8 replicate cages of 20 broilers. The broilers in treatment 1 was fed with the basal diet, while the broilers in treatment 2 was fed with the basal diet supplemented with the non-starch （NSP） enzyme preparation F at 150 g/t. In treatment 1, the basal diet was the corn-soybean meal diet for the broilers from 1-day-old to 21-day-old and the basal diet was corn-soybean- DDGS meal diet for the broilers from 22-day-old to 42-day-old. All diets were pellets. The present results showed that addition of enzyme preparation F in the corn-soybean meal diet could not improve the production performance and the nutrient apparent utilization, but addition of enzyme preparation F in the corn-soybean-DDGS meal diet could improve the production performance of the broilers at the stage of 22-42d or 1-42d and the nutrient apparent utilization of the broilers at the stage of 22-42d.
