Abstract
Summary
1. The addition of 4 μg of synthetic 1-lyxoflavin per g of dry matter consumed in 3 experiments significantly increased the rate of gain and efficiency of feed utilization of baby pigs fed a low fat basal ration including 0.01% protamine. 2. Using a differential assay procedure for lyxoflavin it was found that approximately 67% of the lyxoflavin intake was excreted in the urine. 3. In vitro studies of heart and liver tissue did not indicate any conversion of riboflavin into lyxoflavin.
