A typical 3 oz cooked serving of lamb shoulder contains 27.9 grams of protein (32.8 g per 100 g), which makes it an excellent source of protein. That covers roughly 56% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
Protein accounts for roughly 46% of the calories in lamb shoulder, making it very protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Among the 133 meats in the database, lamb shoulder ranks 7th by protein per serving, and 13th out of all 796 foods on the site. Set against veal chop, another meat entry in the database, a serving carries about 0.7 g less protein (veal chop has 28.6 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.
