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...

Milk and Potatoes Made the World Go Round

Milk and Potatoes Made the World Go Round

Population growth, urbanization and, as a consequence, economic and political development owe much to humankind’s ability to make use of two humble foodstuffs: milk and potatoes. That is the theory put forward by development economist C. Justin Cook, of the University of California, Merced. Read More...

Farms Feel the Heat

Farms Feel the Heat

For many regions of the world home to large dairy herds, climate change models predict substantial shifts in the environment. These shifts look likely to harm milk production. The hunt is on, therefore, to define the causal mechanisms by which climatic variations lower milk yields and to figure out ways to keep the cattle of the future comfortable. Read More...
