INFLUENCE OF ENZYME PREPARATIONS ON THE PHYSIOLOGICAL AND PRODUCTIVE POTENTIAL OF BROILER CHICKENS ON THE BACKGROUND OF REPLACING THE GRAIN PART OF WHEAT WITH TRITICALE It is very important in feeding birds to maximize the use of traditional feed. However, their use can adversely affect the metabolism and productivity of poultry due to the high content of anti-nutrients in them. For the best digestibility of difficult fissionable components of mixed fodders, it is expedient to use exogenous enzyme preparations. The issue of the indisputable positive effect of enzyme preparations Avizim, Natufos and Ronozym on the growth, physiological state and metabolism of broiler chickens when 15 % of wheat is replaced by 15 % triticale is studied. With the introduction of drugs decreased feed intake from 2.1 to 12.1 %, the maximum values when using Ronozym, the minimum — Avizima. A sufficiently high level of metabolic processes in the broiler organism also against the background of the introduction of the preparation Natufos and Ronozym was characterized by high indices in comparison with intact animals by 13.8–15.0 %. In studies, a feature in the digestibility of feed nutrients, expressed in a depression of digestibility of organic matter by 1.7 % in group I and maximum figures (78.61 %) when using Roozim. The detailing of the indices testifies to the marked superiority of the II and III experimental groups over the control ones, the difference in raw protein was 1.1 and 3.3 % (p ≤ 0.05), for raw fat 0, and 2.2 % (p ≤ 0, 05), respectively. The use of Avizima does not significantly affect the digestibility of the main nutrients of the feed, which puts it in the category not effective when used in the triticale diet.Key words: triticale, chickens, broilers, enzyme preparations, physiology, metabolism.
