Cattle’ microbiocoenosis of rumen while various feed ultrafine particles release

Changes in the cattle’ microbiocenosis of the rumen directly impacted the animals’ productivity. And the main role here is played by the feeding type, the animal’s diet, with a predominance of certain components in different periods of cows housing, which create the necessary conditions for the existence and activity of symbiotic microflora, as well as the development of associated pathologies. Earlier detection of these errors will help to avoid many abnormalities of metabolic processes in the body and prevent the decline in the animals’ productive qualities. That is why it is relevant to study the effect of ultrafine particles on the composition of cattle’ microbiota of rumen. In this article, we analyzed the cattle’ bacterial microbiocenosis in response to the introduction of ultrafine particles (FeCo and silicon oxide SiO2 alloy) into their diet. It is revealed that these ultrafine particles do not have a significant qualitative change in cattle’ microflora of the rumen, but shift the bacterial communities balance towards those microorganisms that improve the food digestibility, which allows them to be recommended as food additives to improve the farm animals productivity.
