Barn Lighting and Animal Health

Proper barn lighting creates an optimal environment for animal activities and rest.

Timed lighting can simulate daylight, helping to regulate animals’ circadian rhythms and supporting reproductive cycles and productivity, especially in dairy cows and poultry.

Research shows that cows exposed to extended daylight through barn lighting increase milk production compared to those with only natural light, while poultry benefit from controlled “photoperiods” that improve growth, development, and feed efficiency.

Well-lit barns encourage better access to food and water sources, enhancing regular feeding and hydration habits vital for animal health and weight gain. Animals feel more secure and less stressed in bright but controlled light, which lowers the risk of anxiety-related behaviors and injuries, improves immune function, and boosts fertility. LED barn lights are especially beneficial because their low heat output prevents overheating and their uniform illumination reduces the risk of eye damage.

Quality lighting also allows for improved monitoring of health and behavior, enabling early intervention for any problems that might arise. A well-illuminated barn can lead to lower mortality rates, fewer injuries, and reduced need for medications or antibiotics.
