What the science of light can do for livestock and farmers

Influence of light

Light enters the retina to stimulate natural behaviours, physiology and growth.

Light also penetrates the skull to stimulate hormones necessary for egg production.

Uniform, controlled and coloured lighting reduces stress and encourages positive and natural behaviours.

ALIS™ lamps are developed for livestock vision. LEDs are selected to optimise performance against the domestic fowl photopic response.

Layers and pullets

Lighting design plays a critical role for poultry growers since pullet maturity and layer output is influenced by light.*

Improved behaviour

From week one to five, broilers in the ALIS™ platform performed significantly more perching compared to birds under CFL lamps.

Poultry love ALIS™

Independent scientific trials have shown reductions in mortality, hock and foot pad sores with improvements in litter quality, mobility and perching.

Production Yields

Independent research showed 21.30p gross margin per net kg using ALIS™ lamps and 20.43p for CFL. Difference 0.87p.

With an average final broiler weight of 2.75kg, this equates to 2.39p per bird.

Welfare

ALIS™ inductive power provides constant current with low to zero photometric flicker eliminating stress-inducing strobe effects.

Safety

Inductive power technology means the Power Hubs and Dawn till Dusk (DTD) Control Panels can be located in separate areas from livestock, improving safety and biosecurity.

ALIS™ platform delivers benefits for swine and producer

Pigs need the right light levels so that they can identify each other, communicate and see pen features such as feeders. ‘Dim to red’ lighting, which the pigs perceive as almost darkness, creates visibility for workers.*

Breeding

Short, or decreasing, day lengths reduce time to puberty in males and females, and for sows to return to mating.*

Piglets

Piglet viability and growth benefit from day lengths (15–18 hours).*

Grower finishers

Short day lengths should be avoided (especially in mixed groups), to reduce mounting and aggression by boars*.

Welfare

Regulations state pigs in buildings with no natural light should have at least 40 lux of additional light for a minimum period of eight hours per day.*
