Control of Aflatoxins in Poultry Feed by Using Yeast

Abstract

The present study aimed to determine the detoxification potential of the food industry by-products such as yeast sludge against the harmful effects of aflatoxins on broilers. The objective of this study was to compare the binding capacity of yeast sludge fractions i.e. yeast sludge cell wall (YSCW) and yeast sludge cell solubles (YSCS) against different levels of AFB1 and AFG1. Yeast sludge was sonicated into yeast sludge cell walls and yeast sludge cell soluble. A total of 300 one-day-old chicks were randomly divided into 10 treatments with three replicates per treatment and ten chicks per replicate. The 10 treatments included negative control, three positive control with different levels of AFB1 and AFG1, and three different adsorbents with different levels of combinations of AFB1 and AFG1. AFB1 and AFG1 treatments were offered with different levels of AFs (50, 100, and 150 µg/kg) without toxin binder in the feed while the remaining treatments included 0.5% YSCW and 0.5% YSCS as toxin binders at different levels of AFB1 and AFG1 in a factorial arrangement. Feed and water were provided timely with great accuracy. The Aflatoxins showed a significant effect on production, slaughtering, and serum chemistry parameters. The yeast sludge cell wall exhibited significant effects on the production and slaughtering parameters of chicks. Yeast sludge cell wall also showed a significant effect on the biochemical and mineral profile of chicks. The results confirmed that natural binders are economically effective in commercial poultry production.
