摘　　要：本研究旨在对比两种不同脱霉剂的解毒效果。试验采用霉变玉米,以黄曲霉毒素（AFB1）构建了中度污染模型,选用320只1日龄樱桃谷商品代肉鸭,随机分为5个组（每组4个重复）：A组饲喂基础日粮,B组饲喂基础日粮＋2 kg/t脱霉剂Ⅰ,C组饲喂霉菌毒素中度污染日粮,D组饲喂霉菌毒素中度污染日粮＋2 kg/t脱霉剂Ⅰ,E组饲喂霉菌毒素中度污染日粮＋2 kg/t脱霉剂Ⅱ。试验期35 d。结果表明：（1）C组1-14日龄采食量较B组降低了12.3%（P〈0.05）,与A组不存在显著性差异（P≥0.05）,D、E两组的采食量与C组不存在显著性差异（P≥0.05）,B组的采食量与A组也不存在显著性差异（P≥0.05）;（2）B组21、28、35日龄肉鸭的平均体重较对照组A显著提高了7.2%、13.2%、9.0%（P〈0.05）,C组7、14日龄肉鸭的体重较对照组A降低了9.4%、8.7%（P〈0.05）,D组35日龄肉鸭体重较C组提高了5.7%（P〈0.05）,E组各阶段肉鸭的体重与C组差异不显著（P≥0.05）;（3）B组14-35日龄肉鸭血清球蛋白含量明显高于A组（27.30 g/L比24.16 g/L）,而C、D、E组处于同一水平;（4）21、35日龄肉鸭血清肝酶谷丙转氨酶（ALT）活性的比较中发现,B、D两组ALT活性与A组无显著差异（P〉0.05）,而C、E两组的肝酶活性均显著高于A组（P〈0.05）。由此得出,在非霉变日粮中,添加脱霉剂Ⅰ改善了肉鸭的增重和血液免疫;而在霉菌毒素中毒状态下,肉鸭的采食量降低,增重减少,并且肝脏受到损伤,添加脱霉剂Ⅰ改善了中毒状态下肉鸭增重和肝脏损伤,而脱霉剂Ⅱ效果不明显。This experiment was conducted to study the effects of two different disinfectants.Based on the content of aflatoxin （AFB1）,a mild mycotoxin contamination model was established.A total of 320 1-day-old commercial Cherry Valley ducks were randomly divided into 5 groups （4 replicates per group）.Group A was fed basal diet.Group B was fed basal diet＋ 2 kg/t of mildew I .Group C was fed with mycotoxin and moderate contamination diet.Group D was fed with mycotoxin moderately contaminated diets ＋ 2 kg/t of mildew Ⅰ .Group E was fed with mycotoxin moderately contaminated diets ＋ 2 kg/t of mildew Ⅱ .The test period was 35 days.The results show that （1）The feed intake in group C decreased by 12.3% compared with that in group B （P 〈 0.05） ,and there was no significant difference between group A and group C, groups C,D and E,group B and group A （P ≥ 0.05）.（2）Compared with the control group A the average body weight of group B was increased by 7.2%,13.2%,9.0% at 21,28,35 days （P 〈 0.05）.The body weight of ducks in group C de-creased by 9.4% and 8.7% at 7,14 days （P 〈 0.05）.Compared with group C,body weight of group D was increased by 5.7% （P 〈 0.05）.There was no significant difference in body weight between group E and group C （P ≥ 0.05）.（3）The serum globulin content in group B was significantly higher than that in group A （27.30 g/L vs 24.16 g/L） ,while the group C,D and E were at the same level.（4）The serum liver enzyme ALT activity in groups B and D have no significant differ-ence compare with the control group A,C and E were higher than group A.In concluded,adding mildew-free agent to the non-mildew diet improved the weight gain and blood im-munization of the ducks.In the mycotoxin-poisoned state,the feed intake and weight loss of the ducks was reduced,and the liver was damaged,The addition of de-mildew I im-proved the weight gain and liver damage of ducks in the poisoned state,while
