ABSTRACT
The chemical composition, fatty acid profile, content of amino acids, minerals, and gross energy of seeds of some commercial linseed oily cultivars: brown-seed (Flanders, Opal and brown-seed mixture) and yellow-seed (Hungarian Gold, Linola™947, Linola™989, Hungarian ecotype) were determined. The nutritive value of seeds for ruminants was also assessed according to the Polish IZ-INRA (1997) standards. Lysine was the main limiting AA for all cultivars. There were significant differences between cultivars in the contents of unsaturated fatty acids, C18:2, C18:3. In the Linola™947 and Linola™989 cultivars, the level of linolenic acid (C18:3) was very low (about 2%), but the level of linoleic acid (C18:2) was over 72% of total acids. There were differences between cultivars in PDIN and PDIE.
