Ireland: research on nutrients in grass-fed milk

In Ireland research shows that grass-fed milk contains more beneficial nutrients than milk from conventional indoor-feeding practices. Researchers from Teagasc and Food for Health Ireland (FHI) discovered that dairy cows who operate on an grass-fed system, produced milk with higher percentages of omega-3 and conjugated linoleic (CLA) fatty acids compared to cows fed medium and low proportions of grass. A grass-fed system resulted in 83 percent increase in omega-3 fatty acids, including an improved n-3 to n-6 ratio; 141 percent increase in conjugated linoleic acids (CLA); the highest levels of unsaturated fatty acids (including mono- and polyunsaturated); the lowest levels of saturated fatty acids.
