Which two measures are mentioned for evaluating protein in rations?

• A. Total Protein (TP) and Digestible Protein (DP)
• B. Total Fat
• C. Minerals
• D. Carbohydrates

Answer: (A)

When evaluating protein in rations, you focus on both how much protein is there and how much of it can actually be used by the animal. The two measures you’d look for are Total Protein, which tells you the overall protein content, and Digestible Protein, which estimates the portion that can be digested and absorbed. Total Protein gives a sense of the quantity, but not all of that protein is available; Digestible Protein adjusts for digestibility so you know how much protein the animal can utilize for growth, maintenance, or production. The other options—Total Fat, Minerals, and Carbohydrates—relate to other nutrients or energy, not to the specific measures of protein quantity and availability.
