Protein quality of Lupinus angustifolius - prediction of amino acids and crude protein with near infrared spectroscopy

Summary in the original language of the document

The quality evaluation of organic protein feedstuffs, especially the quick and easy determination of the protein quality including the amino acid (AA) pattern in locally grown legumes like lupins, is very important to fulfil the requirements regarding the protein and amino acid supply of organically fed animals, especially monogastrics. The analytical data of organically cultivated feeds, as compared with conventional table values, shows a clear deviation of protein and amino acids between conventional and organic feeds. The standard tabular values (DLG 2014) are not sufficient for the calculation of feed rations. Therefore the ability of NIRS to predict the chemical composition and the essential AA’s of organically grown lupins was proofed.
