We transformed highly nutritive food waste (yeast) into animal feed, saving costs and reducing farm footprint.

Why does it matter?

Waste from food production is excellent feed for cows, that can replace imported feed.

How did we solve this?

Food companies produce a wide range of by-products when they make their core products. These by-products are full of protein, energy, and digestible fibres. We introduced one of these by-products, yeast, into the diets of our cows. 

Our pilot farm purchased yeast from a supplier located within 200 km every two months. Gradually, rapeseed and sunflower meals were partially replaced, without any impacts on cow performance. Costs fell by €15/cow/year. 

Opportunities for other farms?

It is possible to use a wide range of by-products if quality food suppliers are available nearby and on-time delivery is assured. This transforming of food waste into valuable feed will lead to a decrease in farm footprint.
