1. Introduction

The adoption of LED lighting in poultry farming has gained momentum due to its potential to enhance productivity while reducing energy costs and environmental impact. Traditional lighting systems, such as incandescent and energy-saving lamps, are increasingly being replaced by LED lights for laying hens, which offer superior energy efficiency, durability, and animal welfare benefits. This study evaluates the effects of LED lighting on the production performance of Hy-Line Brown laying hens and quantifies its energy-saving advantages, providing actionable insights for modern poultry farming practices.

2. Benefits of LED Lighting in Poultry Farming

2.1 Energy Efficiency

LED lamps consume 10% of the energy used by incandescent bulbs and 50% of energy-saving lamps at equivalent brightness levels.

Lifespan: Exceeds 50,000 hours, compared to 1,000 hours for incandescent and 5,000 hours for energy-saving lamps.

2.2 Environmental Adaptability

Operates effectively in extreme temperatures (-35°C to 45°C) and high humidity (<95%).

Flicker-free illumination reduces stress in poultry, promoting stable egg-laying cycles.

2.3 Economic Advantages

Lower replacement frequency and maintenance costs due to durability.

Non-toxic materials minimize environmental pollution from discarded lamps.

3. Experimental analysis

3.1 Experimental Design

Animals: 10000 laying hens (148 days old) were divided into two groups:

LED group (5000 hens): Illuminated with 3W LED lamps.

Control group (5000 hens): Illuminated with 9W energy-saving lamps.

Housing: Identical facilities with three-tier cages (70m × 12m), automated ventilation, and standardized diets.

3.2 Lighting Conditions

Illumination intensity: Maintained at 8–13 lux on the chicken head plane (measured using TES-1330A illuminance meter).

Uniformity: Exceeded 73% (minimum-to-average illumination ratio).

Schedule: 16-hour daily photoperiod during the 15-week experimental period.

3.3 Data Collection and Analysis

Metrics: Daily feed intake, mortality, and total egg production.

Statistical methods: One-way ANOVA and Duncan’s multiple comparison test.

4. Experimental Results

4.1 Production Performance

Egg production: 3.78% increase in the LED group (P < 0.05).

Mortality: 0.269% reduction in the LED group (P < 0.05).

Feed intake: Slight increase observed but not statistically significant (P > 0.05).

4.2 Energy Savings

4.2.1 Annual cost per chicken house (40 lamps):

LED: $90

Energy-saving lamps: $277

4.2.2 Farm-wide savings: Switching to LEDs reduced costs by 65.35% ($7,509 annually).

5. Discussion

5.1 Enhanced Egg Production

The consistent, flicker-free light from LEDs reduces stress.

Improved egg-laying stability correlates with optimized light uniformity and intensity.

5.2 Industry Implications

Cost-effectiveness: Despite higher upfront costs, LEDs achieve a 3–5 year payback period through energy savings.

Animal welfare: Reduced flicker and radiation enhance hen health and productivity.

LED lighting for laying hens is a safe, efficient, and sustainable solution that significantly improves egg production while reducing energy costs and environmental footprint. For poultry farms facing rising operational expenses, adopting LED technology represents a strategic investment in long-term profitability and ecological responsibility.
