SDSU dairy research considers history of methane emissions
By SDSU Extension
BROOKINGS, S.D. - Modern dairy cows produce more methane than their predecessors, but fewer dairy herds and a smaller dairy cow population has resulted in less overall methane emission.

Garcia and Linn presented their findings at the 2008 American Dairy Science Association meeting in Indianapolis.

Agriculture has continually been improving its efficiency and this is a great look back at how far we have come. Being able to produce more with less is how we can continue to feed a growing population. This is another one of the great stories that agriculture has to tell.
