| Abstract | ||||
| This experiment was conducted to study the drastic effects of graded levels of atlatoxin-B, on clinical symptoms, residual effects, some blood constituents and histopathological changes in Nile tilapia, O. nifoticus fingerlings. Also, it was conducted for experimenting the inhibiting effects of graded levels of natural, cheap and available two adsorbent agent, namely egg shells(ES) and shrimp wastes(SW) against the adverse effects of aflatoxin-B, contamination of fingerlings diet fed for 8 weeks. The effects of aflatoxin-B1 (AFB1) were severe clinical lesions in the external organs and postmortem symptoms in the internal organs of the aflatoxicated fish. Significant increase in organs indices was calculated. But decrease in dray matter and increase in ether extract of the fish liver were estimated. Significant decrease in hemoglobin concentration, red blood cells count and uric acid and significantly increase in white blood cells count and alkaline phosphatase and transaminases activity were determined. Residues of AFB1 were found in the whole body of the aflatoxicated fish directly at the end of the experiment and tended to decrease after freezing periods. Severe histological alterations were recorded in livers, kidneys, intestines and gills of the aflatoxicated fish. These alterations in all tested organs were increased by increasing level of aflatoxin (200 ppb AFB1).The effects of either adsorbents at levels of 1 and 2%, respectively were useful in reducing the toxic effects of AFB1 on fish, where it increased significantly the hemoglobin concentration, red blood cells count and uric acid in fish blood. Yet, it decreased significantly white blood cells count, alkaline phosphatase and transaminases activity and most of the organs indices. However, these adsorbents (at levels of 1 % ES and 2% SW) alleviated the toxic effects of AFB, on liver composition (OM and EE) of the fish .. Moreover, using these adsorbents at these levels (1% ES and 2% SW) alleviated the adverse effects of AFB1 on the histopathological changes in different internal organs (livers, kidneys, intestines, and gills) of the aflatoxicated fish. | ||||
