Ethological and biological features of the organism of the black-and-white bulls when using natural feed additives in the diets

The authors studied the natural feed additive effect to the behaviour and biochemical blood composition of the black-and-white bulls. As results of the scientific experiment we came to the conclusion that using of the biologically active substance dihydroquercetin as a part of a natural feed additive in livestock feed for the metabolic processes intensity stimulation, the nutrient synthesis intensity and higher rates meat productivity formation.
