Two hundreds and fifty samples of feeds (125 of each of ingredients of plant origin "yellow corn, white corn, soya bean, soya bean meal, wheat and beans" and compound manufactured feed and animal protein concentrates (meat-bone meal, fish meal, poultry offal and mixed feed). Samples were collected from various poultry farms at Giza and Cairo Governorates. Fungal isolation from ingredients of plant origin revealed lower rate of mould contamination in comparison to compound manufactured feed and animal protein concentrates. For instance, Aspergillus species was isolated from 48-68% and 80-100% of feed ingredients and animal concentrates respectively. This findings was correlated with higher levels of mycotoxins in manufactured feed and animal protein concentrates than feed ingredients of plant origin. For aflatoxins and ochratoxin A the mean levels in feed ingredients were ranged from (18-31 ppb and 15-28 ppb, respectively), while in manufactured feed and animal protein concentrates they ranged from (23-42 ppb and 32-47 ppb) respectively.The isolated Aspergillus flavus and A. ochraceus produced significant levels of respective mycotoxins. The induction of aflatoxicosis and ochratoxicosis in quails with particular reference to their partial elimination by garlic and molasses were carried out. The changes in biochemical parameters (AST, ALT, ALP, LDH, total lipid, triglyceride, cholesterol, LDL, HDL and VLDL), also in serum total protein and protein electrophoresis due to aflatoxicosis and ochratoxicosis were significantly improved under supplementation of garlic extract and molasses in diet.
