Scientific and practical aspects of the use of pro-, pre- and synbiotics in the feeding of ruminants againts the background of research conducted in Ukraine

The review article provides up-to-date scientific information on the characteristics, classification and mechanisms of biological action pro-, pre- synbiotics in digestive tract ruminants. literature sources recent years influence synbiotic supplements (when adding them to diets ruminants) metabolic processes body, intensity growth, development quality products obtained from domestic ruminant animals are systematized analyzed. Emphasis is placed fact that degree productive these diet ruminants determined primarily by qualitative composition, technology production, method storage quantity added fodder. It noted main mechanism when entering optimizing composition its microflora, strengthening barrier functions rumen, reticulum, omasum, abomasum intestine, as well activation interferon synthesis blood leukocytes, stimulation immune status.
