摘要
通过研究黄曲霉毒素解毒酶制剂(ADTZ)对饲喂含黄曲霉毒素B1(AFB1)日粮的肉仔鸡生长性能及血液生理生化指标影响,探讨其应用效果。选用672只1日龄AA肉仔鸡随机分为3个处理,每处理设8个重复;分别饲喂基础饲粮、基础饲粮+0.1mg/kgAFB1、基础饲粮+0.1mg/kgAFB1+0.2%ADTZ,试验期42d。结果表明:①与对照组相比,AFB1组平均日增重显著降低(P<0.05),料重比显著提高(P<0.05),日采食量呈下降趋势(P>0.1);ADTZ组生长性能得到改善,与AFB1组相比,日采食量和日增重均显著提高(P<0.05),料重比呈下降趋势(P>0.1);②AFB1组肉仔鸡血清中天门冬氨酸氨基转移酶(AST)活性显著提高(P<0.05),丙氨酸氨基转移酶(ALT)活性提高了13.64%(P=0.094);与AFB1组相比较,ADTZ组血清中AST活性降低了6.46%(P=0.066),ALT活性呈降低趋势(P>0.1)。③各处理对对血清中生长激素、甲状腺激素T3和T4、胰岛素样生长因子-Ⅰ和胰岛素含量影响均不显著(P>0.1)。
This experiment was conducted to evaluate the effects of aflatoxin-detoxifizyme on growth pedormance, blood biochemical and physiological parameters in AA broiler fed with dietary aflatoxin B1,and investigated the applicalion efibct. 672 1-day-age AA broilers were randomly divided into 3 groups, 8 replicates per group with same sex ratio and fed with basal diet,basal diet＋0.1 mg/kg AFB1 and basal diet＋0.1 mg/kg AFB,＋0.2% ADTZ,respectively. The trial lasted for 42 days. The results showed that：①compared with the contro｜,in AFB, group, average daily gain （ADC,） was decreased significantly （P〈0.05）,feed/gain （F/G） was increased （P〈0.05）,and average daily feed intake （ADFI） was decreased （P〉0.1）;growth periormance of chickens was improved in ADTZ group,compared with AFB, group, ADGand ADFI were raised significantly （P〈0.05）,while F/G was decreased （P〉0.1）. ②in AFB1 group,serum aspartate amino transferase （AST） activity was increased significantly （P〈0.05）, alanine amino transferase （ALT）activity was increased 13.64% （P=0.094） compared with that of AFB1 group, serum AST activities of ADTZ group were decreased 6.64% （P=0.066）,ALT activities were decreased （P〉0.1）.③the levels of growth hormone, T3 and T4,insulin-like growth factor-I, insulinum had no significant difference among the three treatments.
