Comparison of nutritive value of new commercial
linseed oily cultivars for ruminants

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, C_18:2, C_18:3. In the Linola™947 and Linola™989 cultivars, the level of linolenic acid (C_18:3) was very low (about 2%), but the level of linoleic acid (C_18:2) was over 72% of total acids. There were differences between cultivars in PDIN and PDIE.
