Unusual Feed Supplement Could Ease Gassy Cows, Reduce Their Greenhouse Gas Emissions
Date: 4.11.2010
Cow belches, a major source of greenhouse gases, could be decreased by an unusual feed supplement developed by a Penn State dairy scientist.
In a series of laboratory experiments and a live animal test, an oregano-based supplement not only decreased methane emissions in dairy cows by 40 percent, but also improved milk production, according to Alexander Hristov, an associate professor of dairy nutrition.
The natural methane-reduction supplement could lead to a cleaner environment and more roductive dairy operations.
