We evaluated the use of urinary sulfur (S) excretion as a measure of sulfur amino acid (SAA) catabolism and the nitrogen/sulfur (N/S) molar balance ratio as an indicator of nonprotein SAA storage in growing piglets. After confirming that an intravenous dose of sulfate is fully recovered in urinary sulfate, we measured urinary S recovery after an intravenous dose of methionine in 6 piglets fed an adequate protein (AP) diet and 6 piglets fed a low protein (LP) diet with normal energy provision… CONTINUE READING
