EU regulations are forcing organic dairy producers to find ‘new’ protein sources. In 2000, the use of hexane-extracted feed was prohibited in organic dairy production, which ended the use of protein meals. The aim of organic farming is to compose a diet of 100% organic feed. It can be difficult to find high-quality organic protein feeds, since there is a shortage of organically produced feed with a high AAT-content. It would be convenient and economical to be able to produce protein feed locally. Cold pressed rapeseed cake is an excellent protein source in organic dairy production and results of our new study will hopefully show that field beans, peas and lupin are also useful protein sources.
