The rational organisation of feeding has always been one of the critical factors in achieving high animal productivity. In domestic pig farming, the priority is to reduce costs by increasing the digestibility of nutrients in the feed and improving the availability of digested nutrients. One of the most important thing needed for this task is the inclusion of enzyme preparations in the compound feed. They are essential in the animal body to increase the digestibility of nutrients in the feed. The purpose of the study was to investigate the effect of the enzyme preparation Fidbest P5000 GT as part of compound feed on the growth, development and feed consump-tion of young fattening pigs. To achieve this purpose, a scientific and economic experiment was carried out. The studies were performed on young pigs of the large white breed between 60 and 210 days of age. Four groups of 12 animal units each were formed according to the principle of analogous groups. Pigs in all groups were kept under the same feeding and housing conditions. To determine the effect of the tested enzyme preparation on the growth and development of the experimental animals, they were weighed and measured every 30 days, taking into account the consumption of the compound feed and its residues the next day. The use of the enzyme prep-aration Fidbest P5000 GT as part of compound feed for young fattening pigs contributes to the growth, devel-opment and reduction of feed costs per unit of production of young pigs. The use of the enzyme preparation Fidbest P5000 GT in compound feeds made it possible to increase the average daily gain in live weight of young pigs by 4.8%, 9.3% and 6.8%, and to achieve a reduction in feed costs by 4.7%, 8.6% and 6.5%, respectively, compared to the young pigs in the control group. The best indicators were in the second experimental group, in which the studied enzyme preparation was added in the amount of 90 g/t to the composition of the compound feed.
