Abstract:

Extensive investigations carried out on the incidence of common and toxigenic fungi revealed that all types of broiler feeds were found to be infested by common as well as toxigenic fungi and none of the samples was free from contamination. Aspergillus species were dominant in all the samples, followed by species of Penicillium, Fusarium, Alternaria and Chaetomium. Highest number of fungal genera (11) were recorded in broiler concentrate feed amended and broiler concentrate feed with coarse of maize flour. Layer feeds showed association of different fungal species. Absidia, Aspergillus, Brevilegnia, Curvularia, Fusarium, Penicillium and Mucor were the major fungal genera isolated from layer feed samples of this region. Toxigenic studies on fungal isolates of poultry feeds revealed that aflatoxin, sterigmatocystin, ochratoxin A, penicillic acid, cyclopiazonic acid, fumonisin B1, HT-2 toxin, moniliformin, deoxynivalenol, nivalenol, T-2 toxin, zearalenone, diacetoxyscirpenol, citrinin, patulin, islanditoxin, roridin E, penicillic acid were the common mycotoxins produced by them. But, the percentage of toxigenic isolates varied with the sample. In all the feed samples, highest number of Aspergillus flavus isolates were found to be toxigenic followed by A. ochraceus for ochratoxin, Penicillium citrinum for citrinin. In sunflower meal more number of Aspergillus parasiticus strains were positive for aflatoxin. It is concluded that high incidence of toxigenic Aspergillus flavus and A. ochraceus strains for aflatoxin and ochratoxin A indicates the probability of presence of these toxins in the feed samples.
