Using Bagasse as a natural adsorbent for aflatoxins in rabbit diets

Abstract

Thirty males growing White New Zealand (WNZ) rabbits of Aged 4 weeks with initial mean weight (750±50g) were divided into 5 equal groups were kept under the same managerial conditions were conducted to determine the effect of feeding dietary bagasse as a source of natural dietary fiber and to adsorbent for aflatoxins or natural contamination in rabbit diets and to evaluate of using dietary bagasse on growth performance of rabbits. The results obtained were : Group fed basal diet supplemented with bagasse at level 6% (T3,) recorded the best LBW (2279.2g) followed by group fed diet supplemented low dose of AFs+ bagasse at level 6% (T5) being (2177.5 g) ,meanwhile, group fed basal diet (control ) (T1) was the worst one being (2087 g) ; group fed dietary bagasse at level 6% and low dose of AFs (75.0ppb) (T5) achieved significantly (P<0.05) the highest (TG) value(1402.0 g) ; rabbits group fed 6% bagasse and groups fed 6 % bagasse with Low aflatoxin dose (75.0ppb) significantly (P<0.05) consumed TFI less than control and other experimental groups ; No significant differences (p < 0.05) were found among TFCR and Adsorption abilities ranged from 94.63-98.10 % the highest adsorption capacity was observed when using 6 % bagasse and 3 hr shaking time at low TAF concentration , while the lowest value of binding was obtained at level 3% bagasse and 1 hr shaking time and high TAF concentration. The study concluded that using dietary 6 % bagasse with Low aflatoxin dose (75.0ppb) in growing rabbit diets significantly improve growth performance and have Adsorption ability at low TAF concentration
