In Canada, most cattle are raised on forages then finished on a high grain diet at under 20 months of age. Grain-finishing is typical because grains like barley and corn generally contain more energy than forages, and Canada’s relatively short growing season means that forage-finished cattle require stored forage in addition to pasture.
Forage-finished beef contains more omega-3 fatty acids and may contain more conjugated linoleic acid (CLA) than grain-finished beef, which has sparked interest among some health conscious consumers. However, current levels of omega-3 fatty acid and CLA in beef do not consistently meet Health Canada labeling requirements and research has found that increasing the levels of these unsaturated fats while maintaining meat quality is challenging.
Oxidation of unsaturated fats in forage-finished beef may negatively impact flavor and odor. This has led to concerns that some forage-finishing methods may yield a premium-priced product that does not deliver on the perceived quality or potential health benefits to the consumer. Continue reading
