A typical 3 oz cooked serving of bison contains 24.1 grams of protein (28.4 g per 100 g), which makes it a very good source of protein. That covers roughly 48% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
About 79% of the calories in bison come from protein, which makes it extremely protein-dense - close to the practical ceiling for a whole food. Foods in this band are the ones that let you raise your protein intake without raising your calorie intake much at all.
Among the 133 meats in the database, bison ranks 40th by protein per serving, and 60th out of all 796 foods on the site. Set against beef liver, another meat entry in the database, a serving carries about 0.6 g less protein (beef liver has 24.7 g per 3 oz cooked).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is measured by weight at 85 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
