Summary
Yellow LED light promotes broiler growth and improves feeding efficiency. This human-friendly light spectrum offers a viable alternative for poultry production, showing age-dependent effects on broiler weight.
Area of Science:
- Animal Science
- Agricultural Engineering
- Poultry Husbandry
Background:
- Previous studies indicate short-wavelength light (blue and green) stimulates broiler growth.
- Short-wavelength light may negatively impact poultry workers.
- Human-friendly light sources are needed for sustainable broiler production.
Purpose of the Study:
- To evaluate the effect of yellow LED light on broiler growth.
- To investigate the relationship between light wavelength and broiler growth parameters.
- To identify human-friendly lighting solutions for broiler farming.
Main Methods:
- 360 female broiler chicks were divided into six lighting groups (white, red, yellow, green, blue LED, and fluorescent).
- Broilers were exposed to different light treatments from 30 to 72 days of age.
- Growth parameters, including body weight and feeding efficiency, were measured.
Main Results:
- Broilers under yellow LED (YL) and green LED (GL) showed increased weight compared to fluorescent light.
- Yellow LED light (YL) improved feeding efficiency at 45 and 60 days.
- A quantitative, age-dependent relationship was found between light wavelength (455-620 nm) and broiler live body weight.
Conclusions:
- Human-friendly yellow LED light is effective for broiler production.
- Yellow LED light offers comparable growth performance to blue and green light.
- This study demonstrates the potential of yellow LED light as a practical and beneficial lighting option in broiler farming.
