Abstract :Experiments were conducted to compare the efficacy of montmorillonite insert ignore into journalissuearticles values(M); and montmorillonite nanocomposite insert ignore into journalissuearticles values(MN); to reduce the toxicity of aflatoxin insert ignore into journalissuearticles values(AF); in broiler chicks from 0 to 42 days of age. A total of 240 chicks were assigned to 6 dietary treatment groups insert ignore into journalissuearticles values(0 g of adsorbents and 0 mg of AF/kg feed, 3 g of M/kg feed, 3 g of MN/kg feed, 0.11 mg of AF/kg feed, 0.11 mg of AF plus 3 g of M/kg feed, and 0.11 mg of AF plus 3 g of MN/kg feed);. Compared to the control, AF alone significantly decreased ADG and feed efficiency. Marked improvements in performance by the addition of MN to AF diet demonstrated the ability of MN to reduce the toxic effects of AF. However, the addition of M can not diminish the growth inhibitory effects of AF. AF intake markedly increased relative weights of liver, kidney, spleen, and pancreas, and resulted in significant alterations of serum biochemical values and enzymatic activities. Chicks fed MN with AF diet had apparent recovery or restoration of AF-induced organ lesions and aberrations in serum profiles, whereas chicks fed M with AF diet had relative organ weights and serum profiles similar to those of chicks fed AF alone, which indicated beneficial effects of MN and nonprotective effects of M. These findings suggest that feeding MN can effectively prevent the adverse effects associated with aflatoxicosis in broiler chicks.
