Resumo
The current study was conducted to elucidate the clinical effect of ochratoxin A in Gallus gallus domesticus and to ameliorate its toxic effects by the development and characterization of highly porous carbon-based adsorbent derived from coconut shell. A series of experiments were performed on one day-old chicks (Group A to F). Clinical signs of the positive control (group B fed on 400 ppb ochratoxin A contaminated feed) included depression, diarrhea, increased water intake, low body weight, high degree of genotoxicity, swollen and hemorrhagic kidneys and liver. Serum alanine amino transferase (ALT), alkaline phosphatase (ALP), creatinine and urea concentration significantly increased while albumin, globulin and total proteins were found significantly low. All these lead to increased mortality. Among adsorbents treated groups, chickens in group C (0.3% of the prepared adsorbent mixed in OTA contaminated feed) and D (0.6% of the prepared adsorbent mixed in Ochratoxin A (OTA) contaminated feed) showed very low pathological effects while group E (0.9% of the prepared adsorbent mixed in OTA contaminated feed) and F (1.2% of the prepared adsorbent mixed in OTA contaminated feed) showed normal behavior, blood biochemistry and well maintained histological structure like that in group A. As a whole, the adsorbents treated groups fed with ochratoxin A contaminated feed, supplemented with different levels of the prepared adsorbent helped to ameliorate the toxic effects of OTA and nearly showed normal clinical signs.(AU)
