Research from the universities of Newcastle (UK) and Kiel (Germany) shows that milk from Jersey cows grazing on a mix of grass and clover contains 70 percent more omega-3 fatty acids than milk from cows fed grass clover silage. If the cows graze on grassland that contains many herbs, the amount of omega-3 fatty acids increases by 15 percent compared to a sod of grass and clover. The ratio between omega-3 and omega-6 fatty acids in this milk is also better for humans. Too much omega-6 displaces the body’s absorption of omega-3. Omega-3 fatty acids protect among others against cardiovascular diseases and high blood pressure.
