Abstract: The main objectives of this work were to investigate; 1- the response of a local Egyptian chicken strain (Inshas) to aflatoxicosis (AF), 2- the effectiveness of using three anti-aflatoxic agents with different mode of actions. The three agents which given continuously for 25 wks( 4-28 wks) are a) Hydrated sodium calcium aluminosilicate (HSCAS)as an adsorbent which demonstrated a high affinity for aflatoxins, b) Mannan oligosaccharide (BioMos®) 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).
Characteristics investigated included: Live body weight, feed consumption and efficiency of feed utilization: relative weight of internal organs (bursa of Fabricius, the thymus gland, spleen, liver), residual AF in the liver, muscles and eggs; immune respectivelyonse against NBVD
Results obtained could be summarized as follow:
1. All traits studied were adversely affected by AF treatment.
2. The three anti-AF agents studied showed significant beneficial effects in ameliorating the adverse effects resulting from AF administration.
3. In most cases, the best protective effects were obtained with MOS and its combinations followed by HSCAS.
4. Radish extract (RE) seemed to be less effective than the other two agents.
5. In many cases, RE antagonized the action of MOS or HSCAS.
6. In conclusion, using anti-AF agents (MOS, HSCS or their combination) have beneficial effects in ameliorating the adverse effects resulting from AF administration.
