A typical 1 oz serving of summer sausage contains 4.9 grams of protein (17.4 g per 100 g), which makes it a moderate source of protein. That covers roughly 10% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 19% of the calories in summer sausage 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, summer sausage ranks 127th by protein per serving, and 503rd out of all 796 foods on the site. Set against turkey hot dog, another meat entry in the database, a serving carries about 0.6 g less protein (turkey hot dog has 5.5 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 28 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
