Two field cases of underpigmented broilers were reported; investigation revealed the presence of ochratoxin but not aflatoxin. A laboratory experiment revealed that dietary ochratoxin A at levels of 4.0 and 8.0 mug./g. lowered significantly (P less than 0.05) the concentration of plasma carotenoids which are an accepted indicator of carcass pigmentation.
