Total Digestible Nutrients of Cotton Seed Cake
TDN % in cotton seed cake is-
- 60%
- 70%
- 80% — Correct Answer
- 90%
Explanation:
Correct Answer: 80%
Cotton Seed Cake (CSC) is an excellent energy source with a high TDN of approximately 80%, despite having a moderate protein content and the anti-nutritional factor gossypol.
Cotton Seed Cake — Nutritional Profile
| Parameter | Value |
|---|---|
| TDN % | ~80% |
| Crude Protein (CP) | ~38–41% |
| Anti-nutritional factor | Gossypol |
| Gossypol detoxification | Iron supplement or FeSO₄ |
| Species resistant to gossypol | Horse |
Roughage vs. Concentrate Classification
| Feature | Roughage | Concentrate |
|---|---|---|
| Crude Fibre (CF) | >18% | <18% |
| TDN | <60% | >60% |
Cotton Seed Cake (TDN ~80%) clearly falls in the concentrate category.
Why Other Options Are Wrong
- 60% → TDN of 60% is at the boundary between roughage and concentrate; below CSC's actual value
- 70% → underestimates CSC's energy value
- 90% → too high; even molasses (~75–80%) does not typically reach 90% TDN
