The present work presents a study on the effect, of feeding broiler chickens on feeds supplemented with animal proteins sources compared to those fed on all plant protein diets, on the uric acid (UA) concentration in blood and some organs. Serum UA showed the highest level, i.e. 11.98 mg/dl in broilers fed on meat and bone meal (MBM), followed by those fed on fish meal supplemented diet (F.M.) i.e. 10.88 mg/dl. The lowest UA value was obtained by those fed on all plant protein diet (PP), being 4.8 mg/dl. Liver UA concentration in birds fed FM and MBM were respectively 6.6 and 7.5 times those fed on PP diet. U.A. concentration in kidney of broiler fed on FM or MBM was almost 10 times that of birds fed on PP diet. With breast meat, thigh meat, skin and joints, UA concentrations were high in chicken fed on FM, MBM diets than those fed on PP diet. It is concluded that all- plant- protein diet produced chicken meat with low level of uric acid.
