An international team of researchers has found that a core cow microbiome dictates dairy cow productivity and methane emissions. In their paper published in the journal Science Advances, the group describes DNA testing they did on rumen microbes in cattle in several European countries and what they found.

As the planet continues to warm due to human-related activities, scientists continue to look for ways to reduce greenhouse gas emissions. In this new effort, the researchers wondered if it might not be possible to reduce the amount of methane released by cattle. Livestock have been found to contribute up to 14.5 percent of such gases worldwide. Far less methane is released into the atmosphere each year than carbon dioxide, but methane is better at trapping heat.

The researchers note that prior research has shown that the primary generator of methane in cows is the rumen—the first stomach. When a cow eats grass, it goes into the rumen, where a host of microbes reside along with other digestive materials. The host microbes work together to break down the carbohydrates via...
