Erythrocyte glutathione reductase activity and riboflavin nutritional status in early-weaned piglets.
The reliability of erythrocyte glutathione reductase activity (EGRAC) as an indicator of riboflavin (vitamin B2) status was determined in 36 piglets weaned at two weeks of age. Total B2 metabolites determined by high-performance liquid chromatography (HPLC) in plasma, red blood cells, and liver were used as reference values. There was no correlation between EGRAC values and total B2 metabolites either in circulation (r < 0.15, p > 0.08) or in liver (r < 0.01, p > 0.95). EGRAC does not appear to be a reliable biochemical indicator of vitamin B2 status in the pig.
