Correct answer: A. Gross energy intake
- A. Gross energy intake
- B. Urinary energy loss
- C. Methane energy loss
- D. Milk energy output
Explanation
Digestible energy equals gross energy consumed minus the energy lost in feces. Urinary and gaseous losses are removed later when calculating metabolizable energy.
