Which measure(s) are used to evaluate protein in a ration?

Explanation:
Protein evaluation in a ration focuses on how much protein is there and how much of it the animal can actually use. Total protein tells you the overall amount of protein present in the feed. But not all of that protein is available after digestion, so digestible protein estimates the portion that is digested and absorbed by the animal. Using both measures gives a clearer picture of the protein supply the diet can meet with. The other options don’t directly quantify protein content or its usable portion: metabolizable energy is about energy, vitamins cover micronutrients, and fat percentage affects energy density, not protein quantity.
