Evaluation of ameliorative efficiency of vitamin E and Saccharomyces cerevisiae yeast on arsenic toxicity in Black Bengal kids

Abstract

Abstract The present experiment was conducted to evaluate the mitigation strategy of the arsenic toxicity induced in Black Bengal kids through dietary supplementation of vitamin E or yeast culture (Saccharomyces cerevisiae) or combination of both. Thirty number of Black Bengal kids (6.15 ± 0.32 kg, 142.87 ± 9.28 days) were divided into equal five groups. Kids under control group (T0) and other treatment groups (T1, T2, T3 and T4) were fed with similar type of basal diet containing concentrate mixture and sorghum sudan grass. Kids under T1, T2, T3 and T4 were fed with 50 ppm arsenic (As)/kg DM of feed in the form of sodium arsenite (NaAsO2). Kids under T2, T3 and T4 were supplemented with Vitamin E (250 IU/kg DM of feed), yeast culture (S. cerevisiae) (4 × 109 CFU/kid/d) and combination of vitamin E and S. cerevisiae with same doses, respectively. The feeding experiment was continued for 20 weeks. Challenge feeding of arsenic (As) significantly (P
