摘　　要：文章旨在探究日粮添加复合酶制剂(Complex Enzyme Preparations,CEP)对肉仔鸡生长性能、血清生化指标和经济效益的影响。试验共计42d,将1200只健康的1日龄白羽肉鸡随机分为4组,每组10个重复,每个重复30羽肉鸡。在初始体重一致的前提下(P> 0.05),与对照组相比,日粮添加200和400mg/kg组肉鸡的终末体重分别显著提高1.9%和2.4%(P <0.05);日粮添加200和400mg/kg组料重比分别显著降低7.6%和8.8%(P <0.05);此外,日粮添加CEP对肉鸡平均日增重和平均日采食量无显著影响(P> 0.05)。日粮添加200mg/kgCEP显著提高肉鸡血清TP、IgG(P <0.05);日粮添加200和400mg/kgCEP显著提高肉鸡血清ALB含量、T-AOC能力(P <0.05);日粮添加CEP显著降低肉鸡血清MDA含量(P <0.05);此外,日粮添加CEP对肉鸡BUN、IgA、IgM含量均无显著影响(P> 0.05)。日粮添加CEP后,饲料价格分别为2.98、2.996、3.012和3.044元/kg,饲料总成本分别为13.21、12.93、12.57和12.60元/只,此外,因生长性能的提高,本试验各组毛利润分别为11.31、11.69、12.42和12.51元/只。在本试验条件下,肉鸡日粮CEP最适添加量为200mg/kg。The aim of this experiment is to investigate the effects of adding complex enzyme preparations(CEP)to feed on the growth performance,serum biochemical indicators,and economic benefits of broilers.This experiment lasted for a total of 42 days.1200 healthy 1-day-old white feathered broiler chickens were randomly divided into 4 groups,with 10 replicates in each group and 30 broiler chickens in each replicate.Under the premise of consistent initial body weight(P>0.05),compared with the control group,the final body weight of broiler chickens fed with 200 and 400 mg/kg feed significantly increased by 1.9%and 2.4%,respectively(P<0.05);The feed to weight ratio of the 200 and 400 mg/kg groups significantly decreased by 7.6%and 8.8%,respectively(P<0.05);In addition,the addition of CEP to the feed had no significant effect on the average daily weight gain and average daily feed intake of broiler chickens(P>0.05).The addition of 200 mg/kg complex enzyme preparation to the feed significantly increased the serum TP and IgG of broiler chickens(P<0.05);The addition of 200 and 400 mg/kg composite enzyme preparations to the feed significantly increased the serum ALB content and T-AOC ability of broilers(P<0.05);The addition of CEP to feed significantly reduced the serum MDA content of broiler chickens(P<0.05);In addition,the addition of CEP to the diet had no significant effect on the content of BUN,IgA,and IgM in broiler chickens(P>0.05).After adding compound enzyme preparations to the feed,the feed prices were 2.98,2.996,3.012,and 3.044 yuan/kg,respectively.The total feed cost was 13.21,12.93,12.57,and 12.60 yuan,respectively.In addition,due to the improvement of growth performance,the gross profit of each group in this experiment was 11.31,11.69,12.42,and 12.51 yuan,respectively.Under the conditions of this experiment,the optimal amount of compound enzyme preparation added to the feed of broilers is 200 mg/kg.
