Abstract

Incidence of different species of Penicillium in poultry feeds (starter, breeder, boiler and layer) and cattle feeds was analyzed. In all twenty three species of Penicillium, Penicillium aethiopicum, Penicillium alli, Penicillium aurantiogriseum, Penicillium brevicampactum, Penicillium camemberti, Penicillium caseifulvum, Pchrysogenum, Penicillium citrinum, Penicillium commune, Penicillium crustosum, Penicillium digitatum, Penicillium dipodomyis, Penicillium discolor, Penicillium expansum, Penicillium flavigenum, Penicillium griseofulvum, Penicillium italicum, Penicillium nalgiovense, Penicillium nordicum, Penicillium olsonii, Penicillium roqueforti, Penicillium rubrum, Penicillium tricolor and Penicillium verrucosum could be recorded in 400 samples of feed samples, poultry feed (280) and cattle feed (120) was analyzed for fungus isolation by dilution plate method, screening of 483 Penicillium species by thin layer chromatography (TLC) and spray reagents for mycotoxin production, 299 strains were positive to be  mycotoxigenic which elaborates a variety of mycotoxins such as Citrinin, Cyclopiazonic acid, Mycophenolic acid, Ochratoxin A, Patulin, Penitrems, PR toxin, Roquefortine C,Rubratoxin and Terric acid etc.

Key words: Penicillium species, mycotoxins, cattle feed, poultry feed.
