2026 Broiler House Lighting Program Guide (0–42 Day Broiler Lighting Schedule)
A well-designed broiler house lighting program is one of the most powerful tools commercial farmers have to influence growth rate, feed intake, uniformity, and final performance in a broiler floor system. Proper lighting management can improve FCR by 0.05–0.10 points, increase daily gain, reduce mortality, and enhance bird welfare — all while lowering energy costs when using modern LED systems.
Quick Answer
The recommended broiler house lighting program for commercial farms (0–42 days) uses high light intensity at the start to encourage feeding and drinking, then gradually reduces hours and intensity to promote rest and better feed efficiency. A typical schedule includes:
- Days 0–3: 23–24 hours light, 30–40 lux
- Days 4–7: 20–22 hours light, 20–30 lux
- Days 8–21: 18–20 hours light, 10–20 lux
- Days 22–42: 18 hours light + 6 hours dark, 5–10 lux
This schedule supports target FCR 1.65–1.75 and mortality below 5% in modern broiler floor systems.
Why Lighting Programs Matter in Broiler Production
Lighting affects almost every aspect of broiler performance. It stimulates feed intake in the first week, regulates bird activity, influences hormone levels, and plays a major role in skeletal development and immune function. Incorrect lighting can lead to poor uniformity, higher mortality, leg problems, and reduced FCR.
Recommended Broiler Lighting Schedule (0–42 Days)
| Age (Days) | Light Hours | Dark Hours | Recommended Intensity (Lux) | Key Objective |
|---|---|---|---|---|
| 0–3 | 23–24 | 0–1 | 30–40 | Encourage feeding and drinking |
| 4–7 | 20–22 | 2–4 | 20–30 | Establish good feeding behavior |
| 8–21 | 18–20 | 4–6 | 10–20 | Promote uniform growth |
| 22–35 | 18 | 6 | 5–10 | Reduce activity and improve FCR |
| 36–42 | 18 | 6 | 5–8 | Maximize feed efficiency and breast meat yield |
Recommended Light Intensity for Broilers
Day-old chicks need higher light intensity (30–40 lux) to locate feed and water quickly. As birds grow, intensity should be gradually reduced to 5–10 lux in the finisher stage.
LED Lighting Systems for Modern Broiler Houses
Modern dimmable LED poultry lights offer significant advantages: 60–70% energy savings, excellent dimming control, uniform light distribution, long lifespan, and full compatibility with automated lighting controllers.
Common Lighting Mistakes in Broiler Houses
- Too much light in the finisher phase
- Inconsistent or sudden changes in light intensity
- Uneven lighting distribution causing poor uniformity
- No dark period
How Lighting Affects Feed Conversion Ratio (FCR)
Proper lighting programs can improve FCR by 0.05–0.10 points by reducing unnecessary activity and improving feed conversion efficiency.
Lighting System Equipment for Broiler Houses
Modern broiler houses should use dimmable LED poultry lights, central lighting controllers, and automated dimmers.
Conclusion
A well-executed broiler house lighting program is a high-return investment that directly improves growth rate, feed efficiency, uniformity, and bird welfare. A properly designed lighting system combined with automated controllers ensures stable performance in modern broiler floor systems.
Frequently Asked Questions (FAQ)
- What is the best lighting schedule for broilers 0–42 days?
Start with 23–24 hours light for the first 3 days, then gradually reduce to 18 hours light + 6 hours dark by day 22. - What light intensity is recommended for day-old chicks?
30–40 lux to encourage feeding and drinking. - Should broilers have a dark period?
Yes. A 4–6 hour dark period improves rest, reduces stress, and supports better FCR. - Are LED lights better for broiler houses?
Yes. LED systems save 60–70% energy, offer precise dimming, and provide uniform light distribution. - How does lighting affect broiler FCR?
Proper lighting programs can improve FCR by 0.05–0.10 points by reducing unnecessary activity and improving feed conversion efficiency.
