A typical 3 oz grilled serving of kielbasa contains 10.5 grams of protein (12.4 g per 100 g), which makes it a good source of protein. That covers roughly 21% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 15% of the calories in kielbasa come from protein, so it is more of an energy food than a protein food. 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 133 meats in the database, kielbasa ranks 109th by protein per serving, and 308th out of all 796 foods on the site. Set against pork hot dog, another meat entry in the database, a serving carries about 0.8 g more protein (pork hot dog has 9.7 g per 1 hot dog).
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.
