Effect of Urea Treatment on Straw Quality
Urea treatment of straw will increase which of the following?
- DCP only
- TDN only
- Palatability and digestibility only
- All — DCP, TDN, palatability and digestibility — Correct Answer
Explanation:
Correct Answer: All the above
| Parameter | Untreated Straw |
|---|
| Parameter | Untreated | Urea-treated |
|---|---|---|
| DCP% | 0% | 4–5% |
| TDN% | 40% | 50% |
| Digestibility | 46% | 70% |
Mechanism
Urea hydrolyses to NH₃ + CO₂. NH₃ acts as alkali, breaking ester bonds between lignin and hemicellulose, increasing cell wall degradability. Urea treatment @ 4% of straw: 100 kg straw + 4 kg urea + 40 litres water (water:urea = 10:1).
