Producing pigs more sustainably can be achieved in many ways. Precision Livestock Farming (PLF) is one of them - after all, with technology it is often possible to determine at very detailed level what certain pigs need in terms of feed, temperature, ventilation or medication. By applying a targeted treatment, better results can be achieved with minimum input. The guest in this 3rd episode of Meet the Expert is Prof Dr Daniël Berckmans, of Leuven KU in Belgium, who is well-known for his attempts to make PLF more applicable in livestock production.
