Gross energy of a feed is most directly measured using a:
Correct answer: D. Bomb calorimeter
- A. Protein digestibility trial
- B. Metabolism cage
- C. Fecal collection unit
- D. Bomb calorimeter
Explanation
A bomb calorimeter measures the heat released when a feed sample is completely oxidized. A metabolism cage is used for collecting excreta during feeding trials, not for directly measuring gross energy.
