The urgency of the investigated problem is due to the fact that enzymatic compositions in the diets of agricultural mammals contribute to better digestion of nutrients, which allows increasing the rate of inexpensive raw materials ‘rich’ in anti-nutritional factors without compromising the health and productivity of the animal. The article is aimed at researching the digestibility of nutrients and the effect of enzyme compositions on the productivity of cows, and on the analysis of changes in live weight and average daily increments, slaughter and meat qualities of experimental young fattening pigs. The leading method of study is conducting scientific, economic and physiological experiments. Studies allow revealing the effects of enzyme compositions on the gastrointestinal tract microflora, which will directly affect the digestibility of nutrients and productive qualities. The digestibility ratios of feed nutrients were greater in the animals of the experimental groups receiving the enzyme compositions. In cows, milk production increased, and milk composition improved. In the experimental groups of pigs, there was an increase in live weight and average daily growth; a high yield of meat was obtained and the best ratio of meat to fat was observed. The results can be used to study metabolic processes in animals.
