Coventry Valley Farm is one of 15 Vermont farms working with Stonyfield Farm Inc., whose yogurt is made with their organic milk, to reduce the cows' intestinal methane by feeding them flaxseed, alfalfa, and grasses high in Omega 3 fatty acids. The gas cows belch is the dairy industry's biggest greenhouse gas contributor, research shows, most of it emitted from the front and not the back end of the cow.
"I just figured a cow was a cow and they were going to do whatever they were going to do in terms of cow things for gas," said Dellert. "It was pretty shocking to me that just being organic wasn't enough, actually. I really thought that here we're organic, we're doing what we need to do for the planet, we're doing the stuff for the soil and I really thought that was enough."
She learned it wasn't. The dairy industry contributes about 2 percent to the country's total greenhouse gas production, said Rick Naczi, a vice president at Dairy Management Inc., which funds research and promotes dairy products. Most of it comes from the cow, the rest from growing feed crops for the cattle to processing and transporting the milk.
