-
- Digestion of grass in the rumen
- Grass (coarse grass) is stored temporary in the rumen
- Course grass is regurgitated from the rumen for further chewing in the mouth
- Saliva that mixes with the feed creates alkaline/medium suitable for micro-organisms
- Feed undergoes microbial fermentation
- Carbohydrates are broken down into volatile fatty acids (VFAs) which include Acetic,butyric and propionic acids
- Gases like methane, CO2 and H2 are released
- Proteins are broken down to amino acids/peptides and ammonia gas is released.
- Amino acids/non essential amino acids are synthesised from ammonia gas and other non-protein nitrogen by micro-organisms
