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.
1. Rumen & Reticulum (also called the âReticulo-rumenâ or simply the âRumenâ): The capacity of an adult dairy cowâs rumen is about 184 liters (49 gallons) and the reticulum is about 16 liters (4.25 gallons). It is one of the most dense microbial habitats in the world.Microscopic organisms called rumen microbes break down (or digest) ingested feed by a fermentation process.The rumen is the major site of fermentation in the cow. There are1,000,000,000 to 10,000,000,000 bacteria per ml, 1,000,000 protozoa per ml, and a variable amount of fungi..
