What is the protein content of barley?

• A. Approximately 6% crude protein
• B. Approximately 9% crude protein
• C. Approximately 13% crude protein
• D. Approximately 20% crude protein

Answer: (C)

Barley grain typically has a moderate crude protein content on a dry matter basis, commonly around 11–13%, with 13% being a representative figure used in many feed tables. Crude protein is estimated from nitrogen content (protein = nitrogen × 6.25), and cereals like barley usually fall in this middle range rather than very low or very high. Among the options, approximately 13% best matches barley’s usual protein level; 6% or 9% would be too low for barley, and 20% is far too high for a cereal grain.
