A typical 1 cup serving of goat milk contains 8.7 grams of protein (3.56 g per 100 g), which makes it a good source of protein. That covers roughly 17% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 21% of the calories in goat milk come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 81 dairy foods in the database, goat milk ranks 21st by protein per serving, and 331st out of all 796 foods on the site. Set against reduced-fat cheddar cheese, another dairy food entry in the database, a serving carries about 1 g more protein (reduced-fat cheddar cheese has 7.7 g per 1 oz).
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 volume at 244 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
