Proximate Principle Category for Indigestible Carbohydrates
The portion of carbohydrate which is not easily digestible — including cellulose, hemicellulose, and lignin — falls under which proximate principle category?
- NFE (Nitrogen-Free Extract)
- EE (Ether Extract)
- TDN (Total Digestible Nutrients)
- CF (Crude Fibre) — Correct Answer
Explanation:
Correct Answer: CF (Crude Fibre)
Crude Fibre (CF) = indigestible carbohydrate fraction — primarily plant cell wall components.
| Fraction | Contents / Digestibility |
|---|---|
| CF (Weende) | Cellulose + hemicellulose + lignin — Low digestibility |
| NFE (Weende) | Monosaccharides + disaccharides — High digestibility |
| NDF (Van Soest) | Hemicellulose + cellulose + lignin + silica — Low |
| ADF (Van Soest) | Cellulose + lignin + silica — Very low |
| NDF − ADF | = Hemicellulose |
