Lighting is a critical factor in poultry production, directly influencing animal welfare, growth, and overall productivity. To understand its impact, it is important to look at how birds perceive and respond to both light intensity and duration.
Chickens perceive light differently than humans, not only through their eyes but also through the top of the skull. They are sensitive to a wider spectrum, including red, blue, green, and ultraviolet light. This makes the choice of lighting essential.
The correct light intensity also affects feed and water intake, aggression, and cannibalism. Adjusting the light at different growth stages helps manage behavior, health, and performance.
Poultry thrive on a consistent day–night cycle. Providing the right light schedule supports activity levels, growth, immune function, and overall health. Proper light duration improves mobility, alertness, and productivity, all of which enhance flock welfare.
Uneven lighting encourages birds to crowd in darker areas for rest or egg laying, which can cause management issues. Unequal distribution may also result in cold, moist litter in unused areas, increasing the risk of poor litter quality and mold formation. Ensuring even light distribution helps birds spread evenly throughout the house and improves overall flock performance.
Light needs vary depending on the age of the birds:
For precise management, dimmable lighting or multiple circuits allow producers to adjust intensity to flock needs. The most effective solution is to automate light schedules and intensity using robust light sensors designed for poultry houses. These sensors provide accurate data and, when connected to farm controllers, enable consistent and optimized lighting management.
