Evaluation of Probiotic to Ameliorate the Toxicity of Aflatoxin in Broiler Chickens

Abstract

The effects of probiotic (Bacillus toyoi, 1x109 cfu/kg) on toxicity of aflatoxin B1 were evaluated using a total of 420 day-old sexed commercial broiler chicks which were divided randomly into 7 groups each of 3 replicates of 20 chicks. The treatments include the control diet uncontaminated with AFB1, three dietary treatments contaminated with AFB1 (200, 400 and 800 mcg/kg) and three treatments diet contaminated with AFB1 plus Probiotic (1000 g/ton) were used from 0-6 weeks of age. This study revealed a reduction in feed intake; weight gain and feed efficiency were observed. Significant interaction (P0.05) between AFB1 and probiotic were observed for their additive effects on body weight, feed intake, feed efficiency, apparent digestibility of protein, fat, fibre and nitrogen free extract (NFE). Probiotic significantly (P0.05) improved body weight, feed intake and feed efficiency, increased apparent digestibility of protein, fat, fibre and NFE. These results suggest that the addition of probiotic in case of aflatoxicosis may ameliorate and improve the performance as well the retention of nutrients with broiler chickens.
