A typical 1 egg serving of goose egg contains 20 grams of protein (13.9 g per 100 g), which makes it a very good source of protein. That covers roughly 40% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
Protein accounts for roughly 30% of the calories in goose egg, making it moderately 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 20 eggs in the database, goose egg ranks 2nd by protein per serving, and 160th out of all 796 foods on the site. Set against liquid egg substitute, another egg entry in the database, a serving carries about 4 g less protein (liquid egg substitute has 24 g per 1 cup).
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 counted by piece at 144 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
