This study was designed to determine whether the biogenic amines phenylethylamine, putrescine, cadaverine, and histamine, alone or in combination, if added at levels above those commonly found in complete mixed rations containing animal by-product meals, would cause lesions or reduce performance in broilers. The levels of biogenic amines used were double those that have been previously reported to cause problems for broilers. Data collected on performance, gross pathology, and histopathology at 3 and 6 wk indicated no significant differences in production parameters among amine treatments. No significant gross lesions or histopathologic changes were evident. This study suggests that the four studied biogenic amines are of little concern to the broiler industry when fed in the amounts utilized.
