Answer
To calculate the DP content for Feed B, we can set up the equation:
Let the digestible protein content in Feed B be denoted as DP_B. Using the given information, we can express the total digestible protein:
40 kg (for Feed A) + DP_B (for Feed B) = Total DP.
This indicates Feed B should complement the DP from Feed A to meet the required total, thus leading us to conclude that D. 6% could be a correct value if it reconciles with total requirements.
