Organic pig production is challenged both on its environmental and economic competitive position. Low feed efficiency combined with dependency on compound feed based on non-local protein sources increases the loss of nutrients, the climate impact, and the need of farmland.

Thereby both the economy and sustainability of the production are compromised. WI-FI deals with these challenges with the focus of optimizing the winter feed of organic sows using roughage and recirculated waste products.

The Project Purpose

The purpose of the WI-FI project is to give new knowledge about roughage intake as well as the energy- and protein needs of outdoor sows in the winter.

 Additionally, new potential types of roughage and recirculated waste products in the market are investigated – and based on this knowledge new sustainable winter-feeding strategies are developed with the right balance of roughage, compound feed, and recirculated waste products. The new feeding strategies are demonstrated in commercial stocks. 

Finally, a tool to assess the climate impact on commercial organic pig farms is developed and tested.
