As a forage plant advances from the vegetative stage to full maturity, its usual nutritional change is:
Correct answer: C. Lower protein and higher fibre
- A. Higher protein and lower fibre
- B. Higher moisture and lower lignin
- C. Lower protein and higher fibre
- D. Lower fibre and higher digestibility
Explanation
Maturing forage develops more structural cell-wall material and lignification, while its crude protein concentration generally falls. These changes usually reduce voluntary intake and digestibility.
