  Abstract
  This scientific study presents the introduction of a feed additive based on betulin in various concentrations and together with a probiotic-based on Bacillis subtilis bacteria into the diet of broiler chickens. The introduction of natural-like technologies with the use of new-generation phytobiotics into the technological cycle of broiler cultivation is very important for science and practice. Production tests were carried out on cross-308 broiler chickens. The positive effect of betulin-based supplements on the growth of body weight due to muscle fiber, and not due to fat deposition, was obtained. The indicators of the biological value of meat products and their technological properties have also improved. Detailed studies of the chest and leg muscles under a microscope were performed. Histological studies of muscle fiber samples revealed significant differences between the control group and the experimental groups. In the samples of experimental groups, where a phytobiotic based on betulin was used, the muscle tissue was more compact, with the completed process of maturation of the tissue and slightly formed fine-drop fat. In contrast to the control group samples, where the process of formation and maturation of muscle tissue (in the thoracic and femoral muscle groups) tended to incomplete maturation with large-drop obesity, which is confirmed by production indicators for the set of live weight with high indicators for fat deposition in the carcass. The use of betulin-based phytobiotics obtained by extraction from birch bark, which have a wide range of effects on the body, makes it possible for the poultry industry to abandon several feed antibiotics and introduce feed additives of domestic production for farm animals and birds.
