Abstract
The article presents the results of studies on the use of synbiotic feed additives based on live spore-forming bacteria of the genus Bacillus, lysates of lactic acid bacteria and yeast to lambs of 10-day-old Volgograd breed in various doses. The use of the feed additive did not have a negative effect on the morphological parameters of the lambs ' blood. Physiological parameters for the entire observation period were within the reference values characteristic of this animal species. The positive effect of synbiotic feed additive was manifested by higher growth rates – an increase in the live weight of the lambs of the experimental groups compared to the control group.
