Feed supplement greatly reduces dairy cow methane emissions
August 5, 2015
A supplement added to the feed of high-producing dairy cows reduced methane emissions by 30 percent and could have ramifications for global climate change, according to an international team of researchers.
In addition, over the course of the 12-week study conducted at Penn State's dairy barns, cows that consumed a feed regimen supplemented by the novel methane inhibitor 3-nitrooxypropanol -- or 3NOP -- gained 80 percent more body weight than cows in a control group. Significantly, feed intake, fiber digestibility and milk production by cows that consumed the supplement did not decrease.
Some vaccines support evolution of more-virulent viruses
July 31, 2015
Scientific experiments with the herpesvirus that causes Marek's disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of severe illness. The research has important implications for food-chain security and food-chain economics, as well as for other diseases that affect humans and agricultural animals.
