Chemicals for Roughage Treatment
Chemical not suitable for the treatment of poor quality roughage:
- Sodium hydroxide
- Chlorine
- Ozone gas
- Acetic acid — Correct Answer
Explanation:
Correct Answer: Acetic acid
Acetic acid is NOT used as a treatment for improving the nutritive value of poor-quality roughage. It is actually used as a treatment for urea toxicity (to neutralise excess NH₃ in the rumen). The established chemical treatments for roughage use alkalis, ammonia, oxidising agents, and specific salts.
Chemical Treatments for Roughage — What Is Permitted
| Chemical Agent | Category | Used for Roughage? |
|---|---|---|
| Sodium hydroxide (NaOH) | Alkali | Yes ✔ (most effective alkali) |
| Chlorine gas | Gas | Yes ✔ |
| Ozone gas | Oxidising agent | Yes ✔ |
| Acetic acid | Organic acid | No ✘ (used for urea toxicity treatment) |
Complete Chemical Treatment List for Roughage
- Alkali: NaOH, Ca(OH)₂, KOH, NH₄OH
- Ammonia: gaseous, aqueous, urea-ammonia
- Acids: H₂SO₄, HNO₃ (strong mineral acids; not acetic acid)
- Salts: NaCl, Na₂CO₃
- Gases: Chlorine, SO₂
- Oxidising agents: H₂O₂, Ozone
Why Other Options Are Wrong
- Sodium hydroxide → IS used for roughage treatment (alkali treatment)
- Chlorine → IS used for roughage treatment (gas treatment)
- Ozone gas → IS used for roughage treatment (oxidising agent)
