Lighting for pig buildings

Light has an impact on the reproductive and growth performance of pigs, as well as the welfare of both pigs and stockpeople; it also contributes to energy use on farm.

The amount of research and literature available on the impact of lighting on these areas is minimal, so we have collated evidence and best practice to help you decide how best to light your indoor or outdoor pig unit.

Lighting review

In our review, we look at trial results of lights currently available for pig farmers. This includes the key light output and power consumption figures.

The principles of lighting

It's important to measure light, make sure any new installations have timers fitted and provide uniform lighting for pigs. Find out about the effects of lighting on pigs in our literatiure review and discover the principles of light in relation to pig production, both from a behavioural point of view and from optimising production.

Use our practical guide for guidance on equipment selection, installation, operation and maintenance. We outline key factors to consider when choosing lighting for pig units – this includes the requirements at different stages of production, as well as measuring light and selecting systems.
