Every 100 kcal of oxtail brings 10.1 g of protein. On that measure it ranks 96th of the 133 meats in this database and 249th of all 796 foods on the site. Measured by weight instead, its 25.9 g per 100 g ranks 76th in its group.
Protein accounts for roughly 40% of the calories in oxtail, 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.
Weight for weight, oxtail has 1.6 g of protein for each gram of fat (25.9 g against 16.5 g per 100 g).
Set against pork shoulder, another meat entry in the database, a serving carries about 0.5 g more protein (pork shoulder has 21.5 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 44% of the 50 g FDA Daily Value for protein.
Mostly bone and connective tissue before cooking; the edible yield from a whole tail is small.

25.9 g. The 3 oz cooked serving used on this page weighs 85 g and so carries 22 g.
10.1 g. That figure divides its 25.9 g of protein per 100 g by its 257 kcal per 100 g, so it does not depend on serving size.
Yes. The protein in oxtail supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own.
About 44%. One 3 oz cooked serving has 22 g, and the FDA Daily Value for protein is 50 g.
