222 Toxo-pathological effects induced by urea in broiler chicks

Evaluation of Urea as a Protein Source in Broiler Diets

“…In contrast to serum urea value, the second group (fed urea during the whole period) and third group (fed urea during growingfinishing period) recorded the highest values (7.63 and 8.19 mg/dl) in comparison to fourth group (2.60 mg/dl) and control one (1.18 mg/dl). Similar results were reported by Kagan & Ballon (1976) and Sharkawy and Mubarak (2003) who found that blood urea was increased significantly (P< 0.05) by the addition of urea to the diet of broiler chicks.…”
