Benefits of Urea Treatment on Straw
Urea treatment of straw will increase:
- DCP
- TDN
- Palatability & digestibility
- All the above — Correct Answer
Explanation:
Correct Answer: All the above
Urea treatment of straw improves DCP%, TDN%, palatability, and digestibility simultaneously. Urea acts as an NPN source that rumen microbes convert to microbial protein, and the ammoniation process also breaks lignocellulosic bonds improving digestibility.
Effect of Urea Treatment on Straw
| Parameter | Normal Straw | Urea-Treated Straw |
|---|---|---|
| DCP % | 0% | 4–5% |
| TDN % | 40% | 50% |
| Digestibility % | 46% | 70% |
Urea Treatment Protocol for Straw
- Rate: @4% of straw weight
- Formula: 100 Kg straw + 40 L water + 4 Kg urea
- Water:Urea ratio: 10:1 for optimum utilisation
- Also: Urea @1% + Salt @0.5% added to cereals and grasses to improve N₂ content and palatability
Why Other Options Are Wrong
- DCP alone → correct, but incomplete
- TDN alone → correct, but incomplete
- Palatability & digestibility alone → correct, but incomplete; all four parameters improve together
