Today is the total arable area in Norway is not big enough that we are able to cover the requirements for our domesticated animals. Norwegian Agricultural Cooperatives reports that imported feed ingredients covers 65 percent of Norway’s total kraftôrbehov.
Essentially, the protein animal feed in the form of soya imported, but now researchers on how Norway can utilize resources to ensure Norwegian produced food without soy from Brazil.

– the project “Foods of Norway” mixes both agriculture, aquaculture and forestry to find ways to produce protein from yeast cells, pulps from wood, algae and seaweed and kelp, says CEO of Norwegian Agricultural cooperatives, Ola Hedstein.
Agricultural cooperatives are among the partners in the project. Margareth Øverland at Norwegian University of Life Sciences (NMBU) leads research work in the “Foods of Norway.” She says that the aim is to adopt new knowledge and technology to partly produce protein in new ways.
– The concept is to create feed ingredients on the basis of biomass, from sources that are currently not is used to either feed or food.
1. Tang as protein source for fish and livestock
Norway has the world’s second longest coastline after Canada. The first non-traditional source overland presents exploits precisely our long coastline using seaweed as a source of protein in animal feed.
– Seaweeds can be used, for food, supplements, chemicals and feed. Focus is on commercial cultivation, it will form the basis for a major production.
NMBU has a long tradition of using seaweed in feed for sheep, pigs, dairy cattle. But they throw not only tanget in matkassa to animals, it must be treated first.
– Seaweeds have a low nutritional value in that it contains a lot of water, has a high ash content and low content of digestible protein. We are upgrading therefore nutritional value by using new technology through a biorefinery process, says Overland.
– We can utilize the kelp in many ways including by extracting the bioactive substances. The research shows that these substances may provide beneficial health effects when added to the feed.
Researchers by NMBU believe our coast has the potential to deliver seaweeds to create value. It seems that his sheep on Røst in Nordland also know.

2. Bacterial who proteinfôrstoff
For over 20 years NMBU researched how BPM can be used as protein in animal feed. Using bacteria that grow on natural gas are getting the produced germ flour.
– This occurs in a bioreactor, where you first harvest biomass and then dries it. Bacterial flour very similar to fishmeal and has a protein content of 70 percent and fat content of 10 percent, says Overland.
germ flour, according to the researcher have a beneficial amino acid for fish from absorbing nutrients.
– is not this process is very costly?
– When we started working on this was natural gas prices high, but today natural gas prices low and fishmeal prices are high. Therefore, we can now produce BPM at a competitive price, said Overland.
3. Pet foods from spruce wood, straw and bagasse from sugar cane
Another advantage Norway has to offer is forest area. For the project “Foods of Norway” has therefore forest played an important role for the development of Norwegian produced feed ingredients.
– Put simply must log is cut into chips, and so one must separate the wood biomass and use various chemical processes the same way we treat seaweeds, says Overland.
the yeast they finally left with will have very high protein value, which the animals can easily exploit.
We have gotten good results from the use of yeast from trees in salmon feed, says the professor.
Overland also points out that in the process excreted several other drugs, and some drugs can be used more other products.
This grana may be fish and livestock in the future.

4. Proteinfôrstoff from yeasts
In the same way as the above retrieves researchers also proteins from yeast.
– We are looking for the yeast that gives the highest nutritional value, good taste and the best effect on your health to animals, says Overland.
5. Biofuels from residues
When scientists develop livestock from trees and seaweed distinction is also out substances that can be used for other useful things.
– When we work processes to make trees and kelp into protein source for fish and other animals, as we develop knowledge which is also relevant for other processes. Our research can thus also be used for other purposes, such as to develop biofuels from biomass, says the professor
The aim of the project is to utilize the biomass maximum, thus they look at how they can use the remains.
– When we have taken the yeast, we are left with leftovers. These can be used to produce biogas. In addition, the minerals used for fertilizer, and then we have one complete cycle, she said.
– Can we drop to import as soy by taking the methods in use?
– we want to be more self-sufficient so that we can increase food security nationally. We will not suddenly be independent of soy, but in time we can become independent of these imports.
