Optimum Temperature and Moisture During Incubation Days 1–18
Optimum temperature & moisture during 1–18 days of incubation are respectively:
- 37.5°C & 60% R.H. — Correct Answer
- 37.2°C & 70% R.H.
- 45°C & 90% R.H.
- 35°C & 80% R.H.
Explanation:
Correct Answer: 37.5°C & 60% R.H.
During the first 18 days of incubation in the setter:
- Temperature: 37.5°C (99.5°F)
- Relative Humidity: 60% R.H.
Incubation Conditions: Setter vs Hatcher
| Phase | Days | Temperature | Humidity |
|---|---|---|---|
| Setter | 1–18 days | 37.5°C (99.5°F) | 60% R.H. |
| Hatcher | 19–21 days | 37.2°C (99°F) | 70% R.H. |
Higher humidity in the hatcher helps soften the egg membrane, making it easier for the chick to pip and hatch. Maximum weight loss during incubation is 12.6% of the original egg weight.
