摘 要:
试验旨在研究基础饲粮中添加复合酶制剂对肉仔鸡生产性能的影响。选择1日龄商品代艾维茵公雏240只，随机分为2组，每组6个重复，每个重复20只，试验期42d。结果表明，加酶组肉仔鸡42日龄平均体重提高6．63％（P〈0.05）；1～42日龄平均日增重提高6．77％（P〈0．05）；各阶段日采食量差异不显著（P〉0.05）；1～42日龄平均料重比下降9．18％（P〈0．05）；1-42日龄饲料成本下降1．83％（P〉0．05）；销售收入提高6．65％（P〈0．05）。[著者文摘]

Abstract:
The aim of this study was to investigate the effects of enzyme preparations supplementation on performance in broilers. A total of 240 1-day-old male Avian broilers were randomly divided into 2 groups with 4 replicates per group and 20 birds in each replicate. The experimental period was 42 days. The results showed that the average body weight increased by 6.63% in enzyme preparations-supplemented broilers at 42 d of age （P〈 0.05 ） and average daily gain was increased by 6.77% from 1 to 42 d of age （P〈0.05）. There were no significant differences in average daily feed intake of broilers in each phase（P〉0.05 ） and enzyme supplementation decreased by 9.18% of F：G from 1 to 42 d of age （P〈0.05）. Average feed cost decreased by 1.83% from 1 to 42 d of age （P〉0.05） and average income increased by 6.65% （P〈0.05）.[著者文摘]
