Foods of Norway has a special focus on breeding strategies to increase the feed efficiency and robustness of fish and farm animals.

Feed efficiency

A unique feature of Foods of Norway is that it addresses feed resource utilization across different fish and farm animal species. The advantages of each species with respect to efficiency are used to convert different feed resources into food.

We will use biomarkers to record maintenance requirement, and prioritize in selection those with reduced degradation loss, but which at the same time grow fast. In dairy cattle, our approach utilizes infrared light as a biomarker. With swine, the CT-scanning will definitely be a core technology of research.

The effect of selection for efficiency is definitely large, with age of slaughter of chickens at 38 days in 1982, while at only 19 days today. If we are to meet future world-wide need for food production, increased feed efficiency is essential: globally, the annual saving of land from genetic improvement in chicken amounts to approximately twice the size of The Netherlands. In addition, the economical return from improved feed efficiency is large. Feed costs represents about 60 % of the total variable costs in the aquaculture industry and 70 % of the total costs in the farm animal industry.
