Broiler rations containing 2, 3 and 4% corn oil were supplemented with normal (125 mg/kg) and higher (175 mg/kg) levels of an antioxidant, santoquin. The rations were stored at high temperature (40 degree C) for up to 42 days. The extent of fat oxidation, in term of thiobarbituric acid (TBA) value, of stored rations was determined at weekly intervals from day one till the end of 6th week storage period. The highest TBA values (0.807 plus minus 0.017) were observed in rations containing 4% corn oil, whereas the lowest (0.508 plus minus 0.018) were recorded in the rations containing 2% corn oil. Oxidation of oil in rations increased significantly (P less than 0.05) with increasing storage period. High storage temperature also significantly (P less than 0.05) affected the oxidation of fat. Supplementation of rations with higher levels of santoquin (175 mg/kg) significantly (P less than 0.05) improved the stability of corn oil against fat oxidation in rations stored at 40 degree C.
