MICROBIAL FERMENTATION: Microbial fermentation is an anaerobic process Microbes live in a symbiotic existence with the host (e.g. Cow) Microbes do not have complete TCA cycle, volatile fatty acids (VFA) are byproducts of their anaerobic metabolism, which the animal can use B vitamins and vitamin K are produced by microbes BACTERIA: Primary bacteria: Degrade the actual constituents of the diet (Cellulolytic and amylolytic bacteria) Secondary bacteria : Use as their substrate the end products of the primary bacteria e.g. Lactate -utilizing propionate bacteria, methanogenic bacteria PROTOZOA: - Utilize starch granules and other readily digestible materials - Presence in rumen liquor sample indicates normal intra-rumen conditions - Form a reservoir of microbial proteins at times of intermittent supply - Curb high rates of starch degradation - Utilize starch granules and other readily digestible materials Electron Micrograph of a Rumen Protozoa with Attached Bacteria.
