Our Buffalo / Bison Jerky meat contains no antibiotics or growth stimulants. The Buffalo are grass-raised and finished with a nutritionally-balanced, all-vegetarian diet consisting of hay forages and grains. Nutritionally, this is a red meat that is lower in fat and cholesterol than skinless chicken, higher in iron and protein than beef, nutritionally-balanced, and contains an optimum balance of Omega 3’s and 6’s. That means you get the best all natural meat. You can taste the difference.
