Cows May Go Green

Cows May Go Green

It’s a tough gig being a cow. Productivity expectations for meat and milk are high, and at the same time, the cow gets a bad rap for belching a potent greenhouse gas, methane, which is a by-product of its digestion. Some people say it’s like driving a car very hard on a winding mountain road and then complaining about the car’s increased exhaust gas emissions. Reducing emissions and fuel consumption while maintaining performance is the golden ambition of car manufacturers. A similar goal is also true for the cow. People in many government agricultural agencies and the Food and Agriculture Organization (FAO) want the beef and dairy industries to use more productive cattle emitting less methane and using less feed i.e., increasing industry production efficiency while decreasing its environmental footprint. It’s a tall order seemingly resisted by the realities of cow biology, however recent ground-breaking research may have opened new opportunities to meet these ambitious aims. Read More...

Lessening the Gas Leak

Lessening the Gas Leak

A team of scientists from four continents has gathered evidence to demonstrate that it should be possible to cut methane emissions from dairy cattle without reducing how much milk they produce nor having to change the conditions in which they are kept. The answer is simply to add an ingredient to their feed. In tests lasting several months, this ingredient, 3-nitrooxypropanol known as 3NOP, cut methane emissions from Holstein dairy cows by about 30%. Achieving such a reduction in enteric methane output across the dairy industry would be a significant contribution to wider efforts to reduce greenhouse gas emissions. Read More...
