Every 100 kcal of lamb liver brings 13.9 g of protein. On that measure it ranks 63rd of the 133 meats in this database and 170th of all 796 foods on the site. Measured by weight instead, its 30.6 g per 100 g ranks 18th in its group.
About 56% of the calories in lamb liver come from protein, which makes it very 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, lamb liver has 3.5 g of protein for each gram of fat (30.6 g against 8.81 g per 100 g).
Set against lamb loin chop, another meat entry in the database, a serving carries about 0.5 g more protein (lamb loin chop has 25.5 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 52% of the 50 g FDA Daily Value for protein.
