Treatment for Urea Toxicity
Urea toxicity can be treated by:
- 5% acetic acid
- 10% acetic acid
- Drenching cold water
- Both a (5% acetic acid) & c (Drenching cold water) — Correct Answer
Explanation:
Correct Answer: Both 10% acetic acid & Drenching cold water
Urea toxicity is treated by two methods: drenching cold water (20–40 L) to inhibit ureolytic activity, and drenching 4–5 litres of 10% acetic acid to neutralise the released NH₃ in the rumen.
Urea Toxicity Treatment
| Treatment | Amount | Mechanism |
|---|---|---|
| Cold water drenching | 20–40 litres | Inhibits ureolytic bacterial activity; dilutes NH₃ |
| 10% Acetic acid drenching | 4–5 litres | Neutralises NH₃ (NH₃ + CH₃COOH → ammonium acetate) |
Why 5% Acetic Acid is Wrong
- The established treatment uses 10% acetic acid, not 5%
- 5% is too dilute to effectively neutralise the toxic NH₃ concentration in the rumen
Urea Toxicity — Quick Reference
- Toxic rumen NH₃: >80 mg/100 ml
- Toxic blood NH₃: >1 mg/100 ml
- Signs: muscle tremors, bloat, excessive salivation, death
Why Other Options Are Wrong
- 5% acetic acid alone → incorrect concentration; 10% acetic acid is the standard treatment
- 10% acetic acid alone → correct, but incomplete; cold water drenching is also used
- Drenching cold water alone → correct, but incomplete; acetic acid treatment is equally important
