SEGES Pig Production is involved in the work on the development of a new filter, which will reduce the risk of infection of airborne diseases in stables.

Outbreaks of infectious animal diseases have serious consequences for animal herds worldwide. In Denmark alone, we spend more than DKK 100 million. kroner annually on reducing diseases in the stables. Airborne diseases in particular can be difficult to deal with because they cannot be completely prevented by ordinary hygiene measures.


However, a new type of ventilation filter can prevent airborne viruses from entering the stables, thus lowering the risk of the animals becoming infected.

By letting all the air that enters the barn pass through a chemical filter, which is illuminated with UV light, the viruses found in the air around the barn can be killed, so that the air that enters the barn is cleaned.

The animals are thus not exposed to the airborne diseases such as influenza and PRRS (porcine reproductive and respiratory disease).

The technology has proven to work in the laboratory, and the next step is to scale up and develop a prototype that can be used in stables. The new filter is a cheap and energy efficient alternative to the filters used today.


The Innovation Fund has granted DKK 9.5 million. kroner for the project, which may be the first step towards a series production. This is done in a collaboration between the producer of stable ventilation Skov A / S, the Danish Technological Institute, Seges L&F and the University of Copenhagen, whose combined competencies will expand the Danish strength position in high-tech food production, including ensuring fewer infected animals in pig production and increasing Danish technology exports.
