Every 100 kcal of duck leg brings 16.3 g of protein. On that measure it ranks 35th of the 133 meats in this database and 115th of all 796 foods on the site. Measured by weight instead, its 29.1 g per 100 g ranks 35th in its group.
About 65% of the calories in duck leg 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, duck leg has 4.9 g of protein for each gram of fat (29.1 g against 5.96 g per 100 g).
