CONCENTRATIONS OF SELECTED VITAMINS AND SELENIUM IN BISON CUTS

We analyzed individual cuts from clod (Triceps brachii), ribeye (Longi ssimus thoracis), top round (semimembranosus), and top sirloin (Gluteu s medius) from 12 fed bison bulls for content of selected vitamins and selenium. The bulls came from producers in the United States and Cana da and had consumed concentrate diets plus hay free choice for at leas t 180 d. The mean nutrient concentrations of all of the bison cuts com bined were as follows (per 100 grams of wet weight): .045 mg thiamin, .253 mg vitamin B-6, 2.131 mu g vitamin B-12, no detectable vitamin C, .848 mu g vitamin A, .047 mg alpha-tocopherol, .013 mg tau-tocopherol , and 25.464 mu g selenium. The nutrient content values did not differ (P > .05) among the cuts of meat. Cuts from individual bulls were dif ferent (P < .05) with regard to alpha- and tau-tocopherols, selenium, and vitamin A but not with regard to thiamin, vitamin B-6, and vitamin B-12 Nutrient concentrations, with the exception of one nutrient, of five bison from the same producer were similar. Great variation was ob served between the alpha- and tau-tocopherols selenium, and vitamin A contents among bison bulls but not among cuts of meat.
