Asda have decided to release a line of free range milk products, obtained from cows that have been kept outside for at least 6 months of the year. The free range milk will carry a Pasture Promise, ensuring not only cows having more licence to roam outside, but also a fairer price for farmers. 4,000 British dairy farmers went out of business in the last ten years as the reduction in the retail prices of the produce failed to match the rising cost of production for the farmers.
