The large expansion of the canola crushing industry that occurred in North America in the last decade has increased the supply of canola meal for the animal feed industry.

Flax is a cool climate crop grown mainly for production of fiber and food. Its seed, linseed, is rich in oil which contains more than 50% of the essential fatty acid alfa-linolenic acid (omega-3). Linolenic acid is converted into eicosapentaenoic acid and docosahexaenoic acid, precursors of eicosanoids such as prostaglandins.
