Effect of lighting on weaner performance

The reduced feed intake of pigs immediately post-weaning is a serious issue in pork production systems. Fluorescent lighting is an energy efficient light source however these lights are not optimal for pig eye sight and so may impact on feed intake. This report aimed to improve post-weaning performance through the use of LED lighting which provides light optimal for pig vision.

Value for producers:

• Improves understanding of effects lighting type has on pig production
• Improves understanding of effects lighting duration has on pig production

Key findings:

• The difference in food intake and weight gain between flourescent lighting and LED in this experiment is indistinguishable
• There was no effect on food intake or weight gain depending on the duration of lighting
• The researches suggest other factors such as reducing mixing stress and understanding social behaviours relating to feeding require further investigation to attempt to increase post-weaning feed intake
