The protein supply to organic pigs and poultry requires careful management to ensure an adequate supply of essential amino acids and to avoid overfeeding. Alternative sources of protein need to be used to supply the balance of amino acids needed.
By-products of manufacturing processes are useful alternatives. Maize germ cake is a by-product of starch and corn oil production, as well as a brewing by-product.
Maize germ cake contains higher levels of essential amino acids than whole maize, but less energy, which should help with rationing for slower growing breeds of pigs and poultry.

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.
