Lighting Management and Broiler Welfare

Lighting conditions in broiler housing significantly affect bird behaviour, health, and welfare outcomes.

Key Facts

Very low light intensity is used in some systems to reduce aggression
Prolonged darkness periods increase the risk of sudden death syndrome in broilers
A minimum 6-hour dark period is recommended for broiler welfare
Dimmer lights suppress activity and can mask lameness problems
Higher light intensity and longer photoperiods promote more natural behaviour

Welfare Considerations

Lighting management in broiler housing is a significant but often overlooked welfare issue. Prolonged low-light conditions suppress activity and mask health problems, while darkness schedules affect circadian rhythms and developmental health. Welfare-conscious lighting management provides adequate intensity for normal behaviour and appropriate dark periods for rest.

What You Can Do

Support welfare standards that specify minimum light intensity and dark periods
Advocate for evidence-based lighting regulations in broiler production
Choose chicken products from certified welfare-assured schemes
Raise awareness about the welfare effects of lighting in poultry systems
Support research into optimal lighting conditions for broiler welfare
