Temperature Zones for Livestock and Poultry
Match the column:
| TABLE-I | TABLE-II |
|---|---|
| 1. Thermo-neutral zone for pig & cattle | (a) 21-24°C |
| 2. Thermo-neutral zone for poultry | (b) 21.1°C |
| 3. Physiological zero temperature for poultry | (c) 18-21°C |
| 4. Comfort zone for pig & cattle | (d) 13-24°C |
| 5. Comfort zone for poultry | (e) 20-26°C |
- 1-e, 2-d, 3-b, 4-a, 5-c — Correct Answer
- 1-d, 2-e, 3-b, 4-a, 5-c
- 1-e, 2-d, 3-a, 4-b, 5-c
- 1-e, 2-d, 3-b, 4-c, 5-a
Explanation:
Correct Answer: 1-e, 2-d, 3-b, 4-a, 5-c
Temperature zones for various animals:
- Thermo-neutral zone for pig & cattle → 20-26°C — the range where metabolic rate is minimum.
- Thermo-neutral zone for poultry → 13-24°C
- Physiological zero temperature for poultry → 21.1°C — below this temperature, egg production is affected.
- Comfort zone for pig & cattle → 21-24°C
- Comfort zone for poultry → 18-21°C
Key Distinction
Thermo-neutral zone is wider than comfort zone. Comfort zone is the narrower optimal range within the thermo-neutral zone.
Why Other Options Are Wrong
- Option B swaps thermo-neutral zones of pig/cattle and poultry.
- Option C swaps physiological zero (21.1°C) with comfort zone for pig/cattle (21-24°C).
- Option D swaps comfort zones of pig/cattle and poultry.
