In order to reduce adverse effects of diets contaminated with Ochratoxin A(OA) on the productivity of birds, effects of fat levels in diets mixed with the OA on the protein and energy metabolism in chicks were studied. Diets with 4.0 ㎍ of OA per gram diet containing 3.0 and 6.0% of soybean oil were fed to White Leghorn chicks of 11-day old for 7 days of the experimental feeding period. Birds fed the OA and soybean oil showed a tendency of increasing the daily gain and feed efficiency and decreasing relative weight of liver and kidney per body weight compared with those fed the diet containing OA alone. The retention of protein, lipids and energy showed an increasing tendency in birds fed diets containing the OA and soybean oil compared with those of birds fed diets containing 4.0㎍/g of OA. And birds fed diets containing OA and soybean oil decreased urinary nitrogen and fecal nitrogen and increased digestibility of protein while the rate of nitrogenous compounds in urine was not different among birds fed experimental diets. Metabolizable energy content of diets and nitrogen balance increased and heat production per MEn intake was decreased in birds fed the OA and soybean oil.
