Abstract: | Two roosters of Single Comb White Leghorn breed were fed on a formula feed containing 2-14C glycine for 16~17 days. The animals were killed and the specific activities of glycine in the tissue proteins and the purine ring of the excreted uric acid were measured. The amount of synthesized glycine in the rooster was calculated by the dilution method based on the specific activities of glycine in the liver protein and the absorbed one. The rooster absorbed about 1 g of glycine and synthesized about 10 g of glycine per day. Quantitative aspect of glycine metabolism in the rooster was discussed. |
