Summary

Poteinindholdet i råvare afgrøderne var ca. 22%, hvilket er langt under niveauet i fiskemel (70-72% protein). Der har derfor været udført forsøg m.h.p. at opkoncentrere proteinindholdet i økologisk raps, ærter, hestebønner og lupin. Der blev benyttet mekaniske metoder (afskalning, formaling og lufttørring. Følgende proteinindhold blev opnået: Raps 29% protein, ærter: 52% protein, Hestebønner: 56% protein og Lupin: 56% protein.
Baseret på dissse proteinkoncentrater blev der fremstillet forsøgsdiæter, hvor fiskemel var delvist erstattet med disse koncentrater.

Summary translation

The protein content of the raw crops was about 22% protein, which is far below that of fish meal (70-72% protein). Therefore, experiments have been carried out with respect to shifting the protein content of organic rape, pea, horse bean and lupine. The methods were basically dry processing including hulling, grinding and air classification. As a result of the mechanical processing the following protein concentrates were achieved: Rape: 29% protein; Pea: 52% protein; Horse bean: 56% protein; Lupine: 56% protein
Based upon the developed protein sources experimental diets were produced, where fishmeal was partially substituted by the prepared concentrates of the selected protein sources.
