It is not the cow that digests the feed but the bacteria in the rumen, which does the most of this work. The rumen contains billion bacteria and more specially, 1 mL of rumen fluid contains 10-50 billion microbes and over 1 million protozoa. These bacteria attach to the feed particles to digest the feed.UMEN (picture 1) : This is the first compartment of the cattleâs stomach and where fermentation occurs, which allows for the digestion of fiber and other feeds. This is the largest compartment of the stomach and can hold up to 50 gallons of digested feed.
Lactic acid fermentation occurs in bacteria, fungi, and animal muscle cells. It's a pretty simple follow-up to glycolysis: the pyruvate molecules are reduced to lactate, while NADH is oxidized to NAD+. In this way, NAD+ is replenished and cycles back through glycolysis.
