Abstract: 【Objective】 The aim of this study was to study the effects of glucomannan-modified montmorillonite and chitosan-modified montmorillonite on the growth performance and immune function of chicks.【Method】 252 8-day-old laying chicks were randomly divided into 7 groups with 6 replicates in each group and 6 chicks in each replicate.The chicks in group 1 were fed with basal feed, the chicks in group 2 were fed with mildewed feed, and the chicks in groups 3 to 7 were fed with mildewed feed supplemented with 0.15% glucomannan-modified montmorillonite, 0.15% chitosan-modified montmorillonite, 0.15% high purity nano montmorillonite, 0.15% glucomannan and 0.15% chitosan, respectively.The test period was 42 days.At the end of the experiment, the growth performance, the immune organ index, the plasma immunoglobulins and immune factors, the spleen immune factors of test chicks in each group were measured.【Result】 Compared with chicks fed with basal diet, the average daily gain, contents of IL-2, IL-4, IL-6 and IFN-γ in serum and spleen and contents of IgA, IgG and IgM of chicks fed with mildewed feed only were significantly decreased (P<0.05).Compared with chicks fed with mildewed feed only, the average daily gain of chicks fed with mildewed feed supplemented with 0.15% glucomannan-modified montmorillonite and 0.15% chitosan-modified montmorillonite were significantly increased, and the F/G and immune organ index were significantly decreased (P<0.05).The contents of IL-2, IL-4, IL-6 and IFN-γ in serum and spleen and the contents of IgA, IgG and IgM in serum of chicks were significantly increased (P<0.05).【Conclusion】 The immune function of chicks were decreased due to mildewed feed, and the two organic modified montmorillonite could alleviate the toxic effect of mycotoxins on chicks and improve the growth performance and immune function of chicks.
