Rumen Microbiology Microbes present in the rumen – symbiotic relationship with the ruminant animal. Microbes in the rumen bacteria protozoa anaerobic fungi Ruminant animal does not have enzymes which are capable of degrading cellulose and related plant polymers. Microbes are responsible for digestion and fermentation of fibrous feeds that the ruminant consumes. Microbes produce volatile fatty acids (VFA), methane, carbon dioxide and ammonia. Ruminant animal uses the end products of microbial fermentation to meet its nutritional needs. Microbes depend on the ruminant to Provide the physiological conditions necessary for them to live

Rumen Microbiology Rumen Characteristics The rumen is an open and continuous ecosystem which provides a constant supply of substrates (by feed intake) to rumen microbes. Large capacity of the rumen provides volume and retention time for digestion/fermentation of fibrous components. Cellulose digestion is a slow process, fibrous feeds must be retained in the rumen for extended periods. This is facilitated by the selective retention of large particles and by enlarged fermentation compartments or blind sac pouches.
