The microflora in the cow rumen includes bacteria, protozoa and fungi. The number of bacteria 109-1010 in 1 rnl of the reservoir, with more than 60 species, was determined the number of bacteria. The number of bacteria of each species depends greatly on the diet of the cow. The protozoa have a much smaller number of bacteria than the bacteria, and they have only 106 in 1 ml of the container, but due to their larger size, the total biomass is similar to bacteria. Fungi (Fungi) in cow rumen has only been studied in recent decades, their position in the rumen ecosystem has not been fully confirmed, some species have been identified. The contribution of the fungus to rumen digestion is not clearly determined, but it is estimated that about 10% of the total microbial biomass is formed by fungal activity under high fiber diets.
The role of the microbiota in the rumen is very important in the digestion of raw fiber to turn them into products of high nutritional value, easily absorbed for cattle. It can be said that the effort of processing straw, grass and other by-products into milk and meat in cows is thanks to this rich microbiome.
