Every 100 kcal of ostrich brings 18.1 g of protein. On that measure it ranks 24th of the 133 meats in this database and 81st of all 796 foods on the site. Measured by weight instead, its 28.1 g per 100 g ranks 48th in its group.
About 73% of the calories in ostrich 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.
Weight for weight, ostrich has 7.3 g of protein for each gram of fat (28.1 g against 3.87 g per 100 g).
Set against beef round tip roast, another meat entry in the database, a serving carries about 0.5 g more protein (beef round tip roast has 23.4 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 quoted here is measured by weight at 85 g, and it covers about 48% of the 50 g FDA Daily Value for protein.
A red-fleshed bird whose meat is closer to lean beef than to poultry.
