Mootral is a natural food supplement which reduces cows’ methane emissions by about a third - the environmental implications are huge. It’s a garlic and citrus extract which has the added bonus of deterring pesky flies, meaning happier cows.
I was fortunate to spend some time on Brades farm at the end of 2019. They make high-quality ‘Original Barista Milk’, and use Mootral in the feed. I was there taking portraits of cows (well, stock photos) and of the farm workers.
