Published in “Sustainability”. Organic monogastric agriculture is challenged because of a limited availability of regional and organic protein-rich ingredients to fulfill the amino acid requirements. The development of novel feed ingredients is therefore essential.

Soya is one of the most important sources of protein in poultry feeding. However, the high crude protein content alone is not sufficient to meet the special needs of poultry on essential amino acids. They need to be supplemented with other components to get optimal amounts and ratios. In poultry, the feeding of raw soya beans is not possible due to digestive inhibiting components (trypsin inhibitors), and must be prepared by thermal treatment. Soya beans have a very high oil content. Full-fat beans can therefore be used in the ration with a maximum of 10 - 12 %.
