Which measure is most useful for judging the nutritive value of a protein for a growing animal?
Correct answer: D. Amino acid balance and digestibility
- A. Crude fibre concentration alone
- B. Ash content without mineral analysis
- C. Feed colour and particle size
- D. Amino acid balance and digestibility
Explanation
Protein value depends on both the availability of its amino acids and their balance relative to the animal's requirements. Crude protein percentage alone cannot show whether the protein supplies adequate usable essential amino acids.
