Gone with the wind: study finds cows fed wine dregs emit less methane

New research has found a convenient and practical use for the leftover material from winemaking that will help two sometimes fiercely competing worlds; the environment and agriculture.When fed the stems, seeds and skins that were left over from making red wine, material known as grape marc, the methane emissions from dairy cows dropped by 20 per cent. The study, conducted at the Victorian Department of Primary Industries dairy research centre, also found that the cows’ milk production increased by 5 per cent, reports The Sydney Morning Herald.
