摘　　要：在模拟制备黄曲霉毒素超标陈化粮的基础上,探究陈化粮对雏鸡料肉比、免疫器官指数和血细胞数量的影响以及乳酸杆菌的恢复作用。选用160只白来航雏鸡,随机分为4组,分别为对照组、高剂量黄曲霉毒素组、低剂量黄曲霉毒素组、高剂量黄曲霉毒素+乳酸杆菌组,攻毒时间为28 d。结果发现,与对照组相比,黄曲霉毒素对雏鸡日增重有显著的阻滞作用;与对照组相比,低剂量黄曲霉毒素组和高剂量黄曲霉毒素组料肉比极显著升高,而添加乳酸杆菌对雏鸡料肉比具有显著的恢复作用(P<0.05)。与对照组相比,黄曲霉毒素对鸡血细胞生成和免疫器官发育具有显著的阻滞作用(P<0.05),导致血细胞合成受阻和免疫器官发育滞后,而乳酸杆菌对鸡血细胞生成和免疫器官发育具有一定的恢复作用。Based on simulating the preparation of aged diet with excessive aflatoxin,the effects of aged diet on the feed-meat ratio,immune organ indexes and blood cell count of chicken,and the recovery effect of Lactobacillus sp.were studied.Thirty-six white Laihang Chicken were randomly divided into 4 groups:control group,high-dose aflatoxin group,low-dose aflatoxin group,high-dose aflatoxin+Lactobacillus sp.group,the test period was 28 days.The results showed that compared with the control group,aflatoxin had a significant retardation effect on the daily weight gain of chicken.Compared with the control group,the feed-meat ratio in the low-dose aflatoxin group and high-dose aflatoxin group significantly increased.Adding Lactobacillus sp.had a significant improvement effect on the feed-meat ratio(P<0.05).Compared with the control group,aflatoxin had a significant retardation effect on the formation of chicken blood cells and the development of immune organs(P<0.05),resulting in the blocked synthesis of blood cells and delayed development of immune organs,while Lactobacillus sp.had some recovery effects on the formation of chicken blood cells and the development of immune organs.
