Occurrence of Toxin-Producing Fungi In Dairy and Poultry Rations

Abstract

Thirty diary and 20 poultry feed rations were collected from Hilat kuku ,Shambat and A lhalfaia during the period (April to July 2008). The samples were cultured on Sabouraud Dextrose Agar (SDA) and Potato Dextrose Agar (PDA) media for the presence of toxin – producing fungi, the 50 samples yielded fungal growth. Seventy –four fungal isolates were identified as belonging to four genera, namely, Aspergillus,Fusarium, Rhisopusand Penicilium . The species included: Aspergillus niger (34), A.flavus (19), A. fumigates (3), Fusarium spp(8),Rhisopus spp(8) and Penicillium spp (2) . Out of the 34 isolates of A.niger, 24 were from the dairy rations and 10 from the poultry rations. All A.flavusisolates were obtained from the poultry rations, and the 3 A. fumigatuswere isolated from the dairy rations .Out of the 8 Fusarium isolates, 3 were from the diary rations and 5 from the poultry rations. Out of the 8 Rhisopus isolaites , 4 were from the dairy rations and 4 from the poultry rations . The two Penicilliumisolates were from the dairy rations
