The influence of gastrointestinal microflora on nitrogen metabolism in rats was studied by analysing the N and amino acid content of urine from germfree (GF) and conventional (CV) rats fed on an 18% casein diet and a protein-free diet. During the casein diet period, significantly greater amounts of N, urea N, allantoin and 3-methylhistidine were excreted in the urine, and the ratio of urea N to urinary N was greater in the CV group than in the GF group.
