Effects of the Growth Performance and Immune Indices of Chicks and the Recovery Effect of Lactobacillus sp.
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.
