The high efficiency of poultry and pigs is based on high-yielding breeds, balanced high-yielding mixed fodders and appropriate animal holding conditions. Recently, the tendency of increasing the efficiency of the nutritional potential of mixed fodder has become of increasing importance in order to reduce the cost of this factor in the production of livestock products. The role of the intermediate link between animals and the nutritional potential of feed is borne by enzymes. A few years ago the question about the use of exogenous enzyme preparations in the composition of feed was controversial. But a better understanding of the action of industrial enzymes, as well as more successfully developed enzyme preparations have changed the situation. Enzymes are now widely used in many countries around the world to improve the quality of feed produced on the basis of barley, wheat, wheat and barley, as well as other cereals. Perspective is the use of enzyme preparations in ration of young pigs in fattening. In our experiments, lysozyme was used to improve the productivity of young pigs. The experiments were carried out at "Iziumsky compound feed plant", Izium district, Kharkiv region and at the farm "Avangard-D" Ltd., Ovidiopolsky district, Odesa region. It was established that feeding of young pigs of mixed fodder enriched with the enzyme preparation "Lysozyme" prevents the growth of average daily increments, live weight of animals and reduction of feed costs per unit of products. The lowest feed costs per unit gain of live weight were set in the experimental group, which comprised 4.2 feeds. unit. That is less in comparison with animals of control group I by 7.0%. The economic efficiency of raising the young from 4 to 8 months of age has shown that the addition of prezime "lysozyme" to the diet of pigs affects the formation of basic expenses and the receipt of net profit per 1 head.
