The effect of the use of exogenous enzymes in poultry feeding depends on a number of factors: on the properties of the enzyme preparation and its dose, composition of the diet, age and cross. The purpose of the research is to study the metabolic peculiarities in the body of broilers with the inclusion of Ronozyme WX and Roxazyme G2 Granulate enzyme preparations in the rations of wheat-and-barley type. Research methods. The object of the research were broilers of the Smena-7 cross. During each experiment, 4 groups of 200 animals each were formed. The experimental material was statistically processed using the Microsoft Excel software. Results of the research. A more pronounced stimulating effect on the hematogenesis and erythropoiesis of broiler chickens was due to the addition of MEC (multienzyme composition) - Ronozyme WX and Roxazyme G2 Granulate. Therefore, in chickens of the 3 experimental group, the hemoglobin and erythrocyte content in the blood was 2.7 g/l and 0.37x1012/l more than in the control analogues. The best effect on the content of total protein, carbohydrates, metabolites of fat metabolism, mineral elements in the blood serum also had the additives of MEC Ronozyme WX and Roxazyme G2 Granulate. With joint additions to the rations of the mixture of tested preparations in chickens of the 3 experimental group, there was a significant (P> 0.95) increase in lysozyme activity in the blood - by 4.7% and bactericidal activity - by 5.6%. Combined supplements of a mixture of enzyme preparations significantly (P> 0.95) increased the concentration of vitamin A in broilers of the 3 experimental group in the blood by 7.7% and liver - by 9.0% and vitamin E in meat poultry of the 3 experimental group in blood by 12.3% and liver - by 8.5%, as compared to the control. Keywords: Broiler chickens, enzyme preparations, morphological and biochemical composition of blood, liver, vitamins.
