説明

Using the cockerels with the artificial anus, experiments were undertaken to compare the excretion of urinary nitrogen constituents of birds fed basal. carbohydrate-free, and carbohydrate- and fat-free diets and of fasted birds. Birds fed carbohydrate-free diet excreted more urinary nitrogen than that fed basal diet. The increased urinary nitrogen excretion of the birds fed carbohydrate-free diet was due to increased urinary uric acid excretion, and ammonia, urea and total creatinine excretion was comparable. Birds fed carbohydrate- and fat-free diet (high protein diet) excreted significantly higher urinary nitrogen, and this was due to increased all urinary nitrogen constituents excretion. Ratio of uric acid to total urinary nitrogen excretion of the birds fed basal, carbohydrate-free and carbohydrate- and fat-free diets and of fasted birds were relatively constant.
