Chemical composition (main ingredients and anti-nutritional factors) of common vetch (Vicia sativa L.) varieties

Summary in the original language of the document

Common vetches are rich in protein, have good protein quality and are therefore very interesting as protein source in organic farming.The chemical composition in the grains of the varieties were analyzed directly after harvest.The pyrimidine glycosides showed contents between 6.7 and 8.2 g/kg for vicine and 0.23 to 1.1 g/kg for convicine. The ensiling led to the reduction of vicine to 60 % and of convicine to 71% of the initial level.
Germination only degraded vicine, but not convicine. The contents of GCA in the tested varieties ranged between 9.6 and 12.9 g/kg and for BCA between 0.03 and 0.06 g/kg. The ensiling process resulted in a strong degradation of the GCA- and the BCA-contents to 40-50% of the initial level. Germination led to marginal effects on the toxins.
