Measurement of uric acid levels in chicken cecal contents

Uric acid levels in the cecal contents of White Leghorn males aged 6, 10, and 24 weeks of age were constant at approximately 2 mg/100 ml. Fecal samples obtained from these birds contained, respectively, 99, 107, and 156 mg/100 ml uric acid. The addition of growth promoting level of antibiotics or other feed additive to the ration of 10-week-old White Leghorn males had no effect upon cecal uric acid levels.
