Energy-Efficient Lighting Control for Broiler Welfare and Savings

Climate protection and rising energy prices have made energy efficiency a critical priority in livestock farming, particularly in energy-intensive broiler production. In Germany, broiler barns typically feature both natural daylight and artificial lighting. When sunlight is strong, light levels can exceed the required minimum of 20 lux—measured at broiler head height—leading to overly bright conditions that can harm animal health. Excessive brightness causes birds to congregate in darker areas, restricting natural behaviour, degrading litter quality, and increasing the risk of footpad lesions. Sensor-based monitoring and adjustment of artificial lighting can maintain optimal light levels, supporting animal welfare while reducing energy consumption. Birds perceive light differently than humans, being sensitive to ultraviolet and infrared wavelengths; overly bright environments induce stress, potentially leading to cardiovascular issues. To ensure proper orientation for accessing feed and water, adequate lighting must be maintained in darker zones, in line with the legal minimum of 20 lux. By integrating sensors to dynamically regulate artificial lighting, barns can balance animal welfare and energy efficiency. BroilerNet.eu
