Individual ribeye cuts from 10 grass- and 8 grain-finished bulls of the same herd were analyzed for vitamin and selenium content. Vitamin A, vitamin E, thiamin, vitamin B6, vitamin B12 and selenium concentrations of ribeye cuts from grass- and grain-finished bulls were similar. Vitamin C and folic acid levels were not detectable in ribeyes from both groups. Ribeyes from grass-finished bulls contained significantly higher quantities of â-carotene (P < 0.0005) and niacin (P < 0.01) and significantly lower (P < 0.0001) quantities of riboflavin than those from grain-finished bulls. Bison ribeyes from both groups were rich sources (>20% Daily Values) of vitamin B12 and selenium and good sources (10–19% Daily Values) of thiamin, niacin and vitamin B6.
