Question

The energy which is available to the animal for useful purpose is:

• A. Digestible energy
• B. Net energy
• C. Metabolizable energy
• D. Gross energy

Hint:

Net energy: useful energy.
GE > DE > ME > NE.
Used for maintenance and production.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Energy is partitioned in different forms.
Each form has a specific definition.

Step 2: Key Formula or Approach:
No specific formula.
Need to understand energy partitioning.

Step 3: Detailed Explanation:
Net energy is the energy available to the animal for useful purposes.
It is the energy used for maintenance and production.
Gross energy is total energy in feed.
Digestible energy is gross energy minus faecal energy.
Metabolizable energy is digestible energy minus urinary and gaseous energy.
Thus, net energy is the useful energy.

Step 4: Final Answer:
Net energy is available to the animal for useful purpose.
Hence, the correct option is (B).
