【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)。更多还原

【Abstract】 This experiment was conducted to evaluate the effects of aflatoxin-detoxifizyme on growth performance,blood biochemical and physiological parameters in AA broiler fed with dietary aflatoxin B 1,and investigated the application effect.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 1 +0.2% ADTZ,respectively.The trial lasted for 42 days.The results showed that:①compared with the control,in AFB 1 group,average daily gain(ADG) 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 performance of chickens was improved in ADTZ group,compared with AFB 1 group,ADG and 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 AFB 1 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,T 3 and T 4,insulin-like growth factor-Ⅰ,insulinum had no significant difference among the three treatments.更多还原
