What is the main effect of treating poor-quality cereal straw with urea?
Correct answer: C. It increases its nitrogen content and improves digestibility
- A. It removes all lignin from the plant material
- B. It converts the straw into a high-fat concentrate
- C. It increases its nitrogen content and improves digestibility
- D. It prevents the straw from being fermented in the rumen
Explanation
Urea treatment supplies ammonia, which increases the nitrogen content and can improve the digestibility and intake of fibrous straw. It does not turn straw into a concentrate or remove all lignin.
