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.
Abstract
Based on simulating the preparation of aged diet with excessive aflatoxin,the effects of aged diet on the feed-meat ratio,immune or-gan indexes and blood cell count of chicken,and the recovery effect of Lactobacillus sp.were studied.Thirty-six white Laihang Chicken were ran-domly 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,af-latoxin 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 for-mation of chicken blood cells and the development of immune organs.
