The aim of the present study was to determine the detoxification potential of the food industry by-products such as yeast sludge (YS) and whey powder (WP) against harmful effects of ochratoxin A (OTA) in broilers. One day old broilers chicks (n=1250) were randomly divided into five groups replicated five times with each replicate having 50 birds. The experimental feed in different groups was as; group A (basal feed), group B (200ppb OTA), group C (200ppb OTA and 0.2% Dried YS), group D (200ppb OTA and 0.2% WP) and group E (200ppb OTA and 0.2% protemyc). OTA adversely affected body weight gain, feed consumption and feed conversion ratio (FCR) of broiler chicks. Haematobiochemical parameters such as alanine amino transferase (ALT), aspartate amino transferase (AST), and creatinine levels raised by OTA feeding were significantly (P>0.05) reduced in YS and WP supplemented group. Residues of OTA were detected in all the tissues studied, with highest levels observed in kidneys, YS and WP significantly reduced the tissue residues of OTA. In conclusion, present study suggested that addition of YS and WP in broilers feed reduce the harmful effects of OTA in broiler chicks as efficiently as protemyc a commercial mycotoxin binder.
