The evaluation of activated dietary charcoal from Canarium schweinfurthii Engl. seed and maize cob as toxin binder in broiler chickens.

Abstract

One hundred and twenty 3-week old male broiler chickens were used to evaluate the effects of dietary charcoal from Canarium schweinfurthii (charcoal A) and maize cob (charcoal B) on aflatoxin B1 toxicosis in broiler chickens. The individually caged birds were randomly allotted to 8 groups of 15 birds and fed in a completely randomised design a diet with either fresh groundnut meal (C-), groundnut meal infested with 22.02 ppb of aflatoxin B1 (C+) or diet C+ supplemented with either 0.2 or 0.4% of charcoal A (A0.2 and A0.4 respectively), charcoal B (B0.2 and B0.4 respectively) or a 1/1 mixture of A and B (M0.2 and M0.4 respectively). The results indicated that the inclusion of charcoal either individually or as a mixture significantly (P 0.05) by the treatments. Both charcoal A and B significantly (P Key words: Aflatoxin B1, Broiler chickens, Canarium schweinfurthii, Maize cob, Plant charcoal, Toxin biner. Cent vingt poussins males âges de 3 semaines eleves en cage dans un dispositif completement aleatoire ont ete utilises pour evaluer l’effet du charbon des noyaux de Canarium schweinfurthii (charbon A), de rafles de mais (charbon B) ou de leur association (M) dans la proportion 1/1 comme capteur d’aflatoxine B1 dans l’aliment de poulet de chair. A cet effet, les poussins ont recu soit un aliment contenant du tourteau d’arachide de bonne qualite (C-) soit un aliment (C+) contenant du tourteau d’arachide infeste d’Aspergillus flavus (22,02ppb/kg d’aflatoxine B1), soit l’aliment C+ supplemente avec 0,2 ou 0,4% de charbon active de noyaux de Canarium (A0,2 et A0,4), de rafles de mais (B0,2 et B0,4) ou de l’association des charbons A et B (M0,2 et M0,4).
