Abstract
This study was conducted at the poultry farm of the College of Agriculture / University of Baghdad. Aiming to study was evaluate the roll of some chemicals (Fylax , Urea) and plant materials such as Cinnamon bark powder and the peels and leafs powder of sour orange in the prevention of the fungus Aspergillus ochraceus and the detoxification of its toxin. Bioassay studies were also conducted to show the toxic effect of Ochratoxin A to broiler chicks. A total of 200 broiler chicks were randomly and equally assigned to 10 treatment of 20 birds per each treatment for period a 30 Days. When chicks diet was contaminated with 1.5 ppm of Ochratoxin A it caused asignificant decrease in the chicks weight rate to ratio of 35.2% and increase the chicks mortality percentage to 25% as compared with untreated. Furthermore, there was a marked increase in the relative weight of kidney , liver, heart, spleen, gizzard and proventriculus with a ratio of 198.11% , 170.6% , 154.5% , 181.2% , 149.2% and 197.2% respectively. Also there was a significant decrease in proportional weight of bursa of fabricius. Ochratoxin A treatment has caused heamatlogical changes in broiler chicks this toxin were significantly (P<0.05) decreased PCV, HB, RBC (erthrocytes) and increased significantly the WBC (leukocytes count). Toxication with ochratoxin A cause a significant (P<0.05) decreased in the ratio of total protein and an increased the ratio of uric acid . Bioassay tests showed that the addition of botanical and chemicals materials to the contaminated diet with Ochratoxin A, have improved the weight rates of chicks as compared with untreated diet. Fylax compound when added at concentration of 0.2% had significantly (P<0.05) improved the weight to ratio of - 5.1%. when the powder of sour orange peels and leaves was added at 5% concentration improvement in weight rate was in a ratio of - 8.2% and the Cinnamon park powder at a concentration 2% gave ratio of - 9.7%. However, the addition 5% Urea to the diet had improved the weight rate to a ratio of - 21.5% as compared with -35.2% Ochratoxin A
