Bison are handled as little as possible. They spend their lives on grass, much as they always have, with very little time in the feedlot. They are not subjected to questionable drugs, chemicals or hormones. The members of the NBA feel so strongly about this that they have a resolution opposing the use of these substances in the production of Bison for meat.
Research by Dr. M. Marchello at North Dakota State University has shown that the meat from Bison is a highly nutrient dense food because of the proportion of protein, fat, mineral, and fatty acids to its caloric value. Comparisons to other meat sources have also shown that Bison has a greater concentration of iron as well as some of the essential fatty acids necessary for human well being. Readers' Digest magazine has even listed bison as one of the five foods women should eat because of the high iron content.
