Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Zea mays (maize) is a common animal feed.
Its nutrient composition is well known.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the composition of maize.
Step 3: Detailed Explanation:
Maize (Zea mays) grains contain about 9.5% crude protein on dry matter basis.
Other options (45%, 16%, 22%) are incorrect.
Soybean meal has about 45% protein.
Thus, the correct protein content is 9.5%.
Step 4: Final Answer:
The crude protein content of maize grains is 9.5%.
Hence, the correct option is (D).
