Relevance. When using protease in the feeding of broiler chickens, the question arises about its effect on other enzyme additives. The solution to this problem can be the use of multienzyme compositions. Methods. The titrometric method for determining nitrogen (according to Kjeldahl), followed by conversion to protein, allows us to evaluate the efficiency of the enzyme complex, taking into account changes in the composition of the diet in different phases of feeding Results. It was found that the use of the multienzyme feed additive “Natuzyme” allows to obtain a high digestibility of feed protein, especially at the final fattening – 84.1%, with the introduction of 5% sunflower meal into the diet.
