This review is dedicated to the study of symbiosis of organisms (actually – between host animal and microorganisms of the digestive tract) with a purpose of improvement of productivity of animals. It presents an analysis of studies on the role of mucous membrane of the rumen in the process of digestion of ruminants, symbiosis in ruminants and non-ruminants species of animals with microorganisms, the efficiency of fermentation in prestomachs and colon and biotechnology basics of using symbiosis livestock and highlights the important contribution of Ukrainian scientists in addressing the above mentioned issues. In ruminants, the ruminal mucous membrane maintains close relations between the host animal and mixed populations of rumen through its bilateral permeability and synthesizing ability. To maintain a constant enzymatic process mucosa can transfer into the cavity of rumen about 0.4 kg glyco-lipo-nucleoprotein complexes. Fermentation in prestomachs is more efficient than the same in the large intestine. In developing biotechnological bases systems, increase productivity of ruminants and non-ruminants must have taken into account the main factors of correction symbiosis.
