Cows rely on their rumen microbiome to digest food and produce milk efficiently. Understanding these microbes could help ...

Machine in Chicago mimics cow's stomach to divert thousands of tons of food waste from landfills Green Era's digester creates both biogas and nutrient rich compost.

Some of that food is broken down further through “chewing the cud,” or ruminating — in which the cow regurgitates some of its feed, gnashes it down further, then swallows it again.

This kept protein and fat levels in the diet stable. They then incubated the feed in rumen fluid—similar to the fluid found in a cow’s stomach—for either 24 or 48 hours.
