Abstract: The development of the poultry industry requires significant costs, which can be reduced through the use of additional feed resources. At the same time, among the causes of death of young animals, diseases of the gastrointestinal tract occupy the main place. The balance between the components of the intestinal microbiocenosis is usually absent, but the intestinal balance can be restored with the help of symbiotic bacteria, additionally administered to the bird with water and feed (probiotic therapy). Taking into account the above, the aim of our research was to study the effect of feed probiotic additive “Enzimsporin” on the body of broiler chickens cross Cobb 500, and most importantly on the production performance and quality of the meat. The experience was conducted in 2018 on the chickens of the broiler cross “Kobb 500” in 2 houses (at 65 260 and goals 65 134) LLC “Grand-Story” (LLC “Beckys”) from day-old to 42 days. The bird was kept in four-tier cell batteries. Groups of broiler chickens for scientific and economic expertise were chosen on the principle of counterparts, taking into account age, body weight, health status, cross and divided into 2 groups: control and experimental, in the diet which was introduced feed additive “Enzimsporin”. As a result of the studies it was found that the use of “Enzimsporin” had a positive effect on the increase in live weight of poultry at all stages of cultivation, the safety of broiler chickens – increased by 0.6 %; protein by 1.35 % relative to control; changes in morpho-biochemical parameters of blood, as evidenced by the increase in the number of red blood cells and hemoglobin, the number of leukocytes to the final period of research. The studied feed additive increased, within the normative data, the level of LHC, reduced the amount of amino-ammonia nitrogen, did not have a significant effect on the acidic, peroxide amount of fat, did not destroy the enzyme peroxidase, did not change the contamination of meat with microflora. These data suggest that “Enzimsporin” changed the processes of decarboxylation and deamination of amino acids during the maturation of meat after slaughter, which contributed to the change of technology of meat.
