Recently, the use of ecologically safe and biologically active elements and drugs that have a positive impact on the biochemical, immunological, hematological and productive indicators of animals and birds have become of great importance in their feeding. In this regard, the use of extracts of a number of plants, probiotics, as well as organic acids and other additives of natural origin is of great interest. The studies were conducted on laying hens of the cross Rodonit, 180 days of age, on the basis of the Department of Therapy and Clinical Diagnostics of Kazan State Academy of Veterinary Medicine.
