Abstract:
Objective To test whether urinary sulfur excretion can be used as an accurate indicator of the catabolism of sulfur amino acid in growing newborn piglets. Methods Using a well-nourished enteral nutrition piglet model,we tested whether intravenous inorganic sulfate and methionine were fully excreted as sulfur in the urine. Results Recovery rate of inorganic sulfate and methionine as total sulfur in urine were 95.6% and 105.5%, respectively. Conclusions Detection of urinary sulfur, as a non-tracer and noninvasive method, may be employed to accurately measure the catabolism of sulfur amino acid in the growing piglet model.
