Reducing the Toxicity of Aflatoxin in Broiler Chickens' Diet by Using Probiotic and Yeast

The aim of this study was to evaluate the aflatoxins (AFS) removal ability of probiotic bacteria and yeast. There were 271-day-old broiler chicks randomly divided into 9 experimental groups. The criteria of evaluation included body weight gain (BWG), feed consumption, and feed conversion ratio (FCR). The toxic effects of aflatoxins were apparently in groups received AFS contaminated diet which showed significantly lower BWG and FC and impaired FCR compared with control diet. Such effects could be overcame by adding probiotic bacteria and yeast to aflatoxin treated groups. On the other hand, AFS treated group showed significant increase in liver and kidney functions. The intakes of probiotic with yeast significantly alleviated the elevation of ALT, AST, urea, and creatinine levels. The results indicated the effect of probiotic plus yeast as a potential protective agent against aflatoxin toxicity which decrease the risk of occurrence of liver and kidney dysfunction.
