This methodology involves the reduction of greenhouse gas (GHG) emissions from milking cows by feeding them a dietary supplement that reduces GHG emissions. These accepted supplements include: canola meal; cold-pressed canola meal; brewers grain; hominy meal; or dried distillers grain. This reduced GHG emissions like methane from rumen, cow emissions of nitrous oxide and methane emissions from dung and urine. The method can be applied to milking cows in Australia that are pasture grazed for at least 9 months of the year.
