TAXONOMIC DIVERSITY OF RUMINANT RUMEN UNDER THE INFLUENCE OF ULTRAFINE IRON PARTICLES

The article presents the results of an experiment that showed that Thermoplasmata bacteria predominate in the rumen microbiota when using sunflower oil in ruminant feeding, iron significantly affects the level of bacteria of the class Methanobacteria, Methanomicrobia. The use of UDP Fe with sunflower oil in cattle feeding leads to an increase in the intensity of microbiological processes in the rumen and changes in the status of "bacteria-protozoa", have a positive effect on the intensity of metabolic processes in the rumen and can be used to increase the productivity of ruminants.
