Proteinforsyningen til økologiske grise og fjerkræ kræver omhyggelig styring for at sikre en tilstrækkelig forsyning af essentielle aminosyrer og for at undgå overfodring. Alternative proteinkilder skal bruges til at levere den nødvendige balance af aminosyrer.
Biprodukter fra fremstillingsprocesser er nyttige alternativer. Majskimkage er et biprodukt fra produktionen af stivelse og majsolie, såvel som et bryggebiprodukt.
Majskimkage indeholder et højere indhold af essentielle aminosyrer end hel majs, men mindre energi, hvilket skulle være en hjælp til rationering af langsomt voksende svine- og fjerkræracer.

This practice abstract was elaborated in the Organic Knowledge Network on Monogastric Animal Feed project. The project is running from January 2018 to December 2020. The overall aim of OKNet EcoFeed is to help farmers, breeders and the organic feed processing industry in achieving the goal of 100% use of organic and regional feed for monogastrics.
