Blue light: Lowers blood pressure, reduces stress, improves feed conversion, and increases muscle mass.

Green light: Enhances early growth, calcium absorption (beneficial for eggshell quality), and skeletal muscle development.

Red light: Stimulates activity, feed intake, and sexual maturity; extends laying periods but may increase aggression.

UV light (~320-400nm): Improves food/group recognition, parasite reduction, and Vitamin D synthesis for bone/eggshell health.

Intensity: Minimum requirements vary:

Broilers & Laying Hens: ≥20 lux over ≥80% of floor area.

Breeding Birds: 40-60 lux.

Excessively low intensity (<5 lux) increases inactivity, foot lesions, and eye issues; high intensity can trigger cannibalism.

Photoperiod (Duration & Rhythm): Critical for regulating reproduction, growth, and behavior.

Broilers: Initial continuous light (20 lux) tapers to intermittent schedules.

Layers: 15-16 hours of light stimulates gonad development, ovulation, and peak egg production.

Sudden light changes cause stress; gradual "sunrise/sunset" simulations via dimming are essential.

2. LED Technology: The Superior Solution

Traditional lighting (incandescent, fluorescent) is being replaced by LEDs due to proven advantages:

Energy Efficiency & Sustainability: LEDs consume significantly less energy (up to 75% reduction vs. incandescent) and lack hazardous materials like mercury.

Spectral Tunability: LEDs can emit specific wavelengths (monochromatic) or broad-spectrum "white" light tailored to poultry's needs and growth stages (e.g., cool white for weight gain, warm white for layers).

Flicker-Free & Dimming Capability: High-quality LEDs eliminate imperceptible flicker (a major stressor perceived as predator threat) and enable smooth intensity transitions, mimicking natural dawn/dusk and reducing panic.

Durability & Longevity: Resistant to humidity/dust (IP65 rating), with lifespans exceeding traditional bulbs, reducing replacement costs.

3. Smart Lighting Systems & Proven Benefits

Intelligent LED systems dynamically adjust spectrum, intensity, and photoperiod based on poultry species, age, and production goals:

Enhanced Performance: Farms using optimized LED systems report:

Increased weight gain (broilers) and egg production (layers).

Improved feed conversion ratios (FCR), reducing feed costs.

Higher survival rates and lower mortality.

Reduced leg disorders and abnormal behaviors (e.g., feather pecking).

Economic Returns: Case studies show full ROI within 1-2 years due to energy savings, reduced mortality, lower medication/veterinary costs, and improved productivity.

Welfare & Sustainability: Reduced stress, better health, and lower environmental impact (energy savings, no mercury).

Scientific lighting management, particularly using tunable, flicker-free LED systems with intelligent controls, is fundamental to modern poultry farming. By aligning light spectrum, intensity, and photoperiod with poultry biology, producers can significantly improve animal welfare, production efficiency, and farm profitability while reducing environmental footprint. Continued adoption and optimization of this technology represent the future of sustainable poultry production.
