Light Requirement for Broilers
Complete Answer & Explanation
Question (English)
Light requirement for a broiler is:
- 10 hours
- 16 hours
- 18 hours
- 23 hours ✓ Correct
Explanation:
Correct Answer: 23 hours
Broilers require 23 hours of light per day. This near-continuous lighting encourages more feed consumption, maximizing daily weight gain and achieving market weight (1.5–2 kg) within 6 weeks.
Why Near-Continuous Light for Broilers?
- Broilers are raised purely for rapid meat production. Light keeps them active and eating for more hours per day.
- 1 hour of darkness per day is maintained as a precaution: if a power failure occurs, birds that have never experienced darkness may panic and pile up (smothering death). The 1-hour dark period acclimatizes them.
Light Summary
| Poultry Type | Light Hours | Purpose |
|---|---|---|
| Layer | 16 hours | Stimulate ovulation & egg production |
| Broiler | 23 hours | Maximize feed intake & growth rate |
