The study also evaluated the relationship between the intake, retention, and output of nitrogen as well as the uric acid output of the birds. In Experiment 1 (14 to20% CP diets), nitrogen and uric acid excretion increase linearly (P < .01) with nitrogen intake. Proportional nitrogen retention decreased linearly (P < .01) with increased dietary protein. In Experiment 2 (9 to 15% CP diets), both nitrogen and uric acid excretion increased linearly (P < .05) with nitrogen intake. Also, a trend was observed of nitrogen retention (g/bird/day) increasing as dietary protein increased. Results indicate that an increase of nitrogen intake is positively correlated with nitrogen output, a finding suggesting that higher nitrogen intake does not cause higher nitrogen retention. © 1995 Applied Poultry Science, Inc.
