Abstract
Two roosters of the Single Comb White Leghornbreed with artificial anus and four adult male rats were fed on a protein-depleted diet for 8 days. Urine and feces were collected separately and analyzed for nitrogen contents by the Kjeldahl method and for glycine contents by the ninhydrin oxidation method.
The mean values of the metabolic fecal glycine, metabolic fecal nitrogen, and endogenous urinary nitrogen were 13.5, 45.0, and 213.9 mg per head per day, respectively, for the fowl and 8.3, 24.5, and 62.4mg per head per day for the rat.
From these results, it is evident that each yalue per 100g of body weight is smaller in the fowl than in the rat.
