A typical 1 cup serving of sheep milk contains 14.7 grams of protein (5.98 g per 100 g), which makes it a good source of protein. That covers roughly 29% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 22% of the calories in sheep 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, sheep milk ranks 12th by protein per serving, and 255th out of all 796 foods on the site. Set against ricotta (part-skim), another dairy food entry in the database, a serving carries about 0.6 g more protein (ricotta (part-skim) has 14.1 g per 1/2 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 measured by volume at 245 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Sheep milk is far richer in solids than cow milk, which is why it yields so much cheese.
