Abstract. The research was carried out to determine the efficiency of growing fattening pigs using the feed additive " Hostazym Combi". For the scientific and economic experiment, which was carried out from August 2021 to February 2022 under the conditions of a farm in the Republic of Bashkortostan, 3 experimental groups were formed – 6 heads each. in each. The objectives of the research included the study of growth intensity, exterior features, haematological changes, slaughter parameters of fattening young pigs and the calculation of the economic efficiency of fattening pigs. In the control group, the animals received the main diet in the form of concentrates mixed with water and boiled potatoes, according to the design adopted in the farm. In the 1st and 2nd experimental groups, along with the main diet, they were given the feed additive " Hostazym Combi" in doses of 0.2 and 0.3 g/kg of feed, respectively. Higher fattening productivity was observed in the group whose animals received the supplement at a dose of 0.3 g/kg of feed. They were ahead of their peers in the control group in terms of average daily gain in live weight by 167.6 g, or by 44.5% (p<0.001). In the same group, higher, compared with the control, exterior indicators were recorded (index of knockdown – by 0.8%, specific gravity – by 4%, massiveness – by 0.15, p>0.05), as well as protein content (by 12.4%, p<0.001) and its fractions (albumin – by 6.5%, p<0.001) in blood serum. The level of profitability of commercial pork production in the 2nd experimental group was 62.1%, which is higher than in the control by 5.4%, compared with the 1st experimental group – by 1.0%.
