Asda, the UK’s second largest supermarket, has recently introduced the Pasture Promise brand, which has been developed to identify milk that is ‘free range’. This, according to their definition, means it comes from cows that have “grazed outside for at least 180 days a year”. Compared to ‘normal’ milk which may come from cows that never go outside, this is a massive improvement. It’s also an improvement on the initiative pushed by another British supermarket Waitrose, which last year reported its milk comes from dairy cows that spend 100 days a year grazing outdoors, and this year have expanded their commitment to 120 days. But can more be done?
