Effect of some natural feed additives on immune response and residual AF of young chickens fed aflatoxic diets
Abstract: An experiment was designed to investigate the response of a local Egyptian chicken strain (Inshas) to aflatoxicosis and the effectiveness of using three anti-aftatoxic agents with different mode of action when added to AF -contaminated diets either singly or in combination. The three agents were (a) Hydrated sodium calcium aluminosilicate (HSCAS) as an adsorbent which demonstrated a high affinity for aflatoxins, b) Mannan oligosaccharide (Bio- Mos®) as a biological derivative, c) Radish extract (RE) as an antioxidant agent rich in peroxidase enzyme). A total number of eight hundred and ten unsexed Inshas day old chicks were divided into nine experimental groups of 90 chicks each ( three replicates/ each group) being: control and 8 dietary treatments as follows ;
(T1) Basal diet + AF(1.0mg total AF/kg diet) , (T2) Basal diet + AF+ Bio-mos (1.0g/kg diet) , (T3) Basal diet +AF+ RE(10g/kg diet) , (T4) Basal diet +AF+ HSCAS(0.5%) , (T5) Basal diet + AF+ Bio-mos + RE, (T6) Basal diet +AF+Bio-mos +HSCAS , (T7) Basal diet +AF+RE + HSCAS , ( T8) Basal diet +AF+Bio-mos +RE + HSCAS , and (T9) Basal diet ( control ). Feeding treatment started at 4 wk of age and lasted for 16 wk. Characteristics investigated included; immune response against NBVD and residual AF in the liver, muscles and eggs.
Results obtained could be summarized as follows:
All traits studied were adversely affected by AF treatment. The three anti - AF agents studied showed significant beneficial effects in ameliorating the adverse effects resulting from AF administration. In most cases, the best protective effects were obtained with MOS and its combinations followed by HSCAS. Radish extract (RE) seemed to be less effective than the other two agents. In many cases RE antagonized the action of MOS or HSCAS .
