Correct answer: B. Lysine
- A. Glycine
- B. Lysine
- C. Alanine
- D. Glutamic acid
Explanation
Lysine is commonly the first limiting amino acid in cereal-based pig diets because cereal proteins supply it in relatively low amounts. The other listed amino acids are generally not the first limiting amino acids in such rations.
