Abstract. Broiler poultry farming is a highly efficient sector of agriculture of Russia. Russia is in the process of modernization of existing production capacities. At the same time the construction of the new automated poultry systems allows to create optimal conditions for growing highly productive birds. However, despite the achieved level of development, there are significant problems that needed to improve production efficiency. The microbiological preparations used in poultry farming with the aim of increasing productivity and disease prevention. The article presents the results of a study of hematological and biochemical parameters of blood of chickens-broilers of the cross “ROSS 308” when used in the diet of microbiological preparations. Marked increase in blood birds of the experimental group in hemoglobin, red blood cells and total protein. The positive influence of these preparations on the metabolic processes in the bird body has been proved. It is established that the number of leukocytes throughout the experience in all groups was within the physiological norm. 14 days in I and II experimental groups showed insignificant decrease in the number of leucocytes relative to control group by 5.67 % and 9.17 %, respectively. The level of urea in blood serum characterizes the degradation of amino acids in the liver. In our researches it is established that the birds I experimental group the blood urea was significantly higher than in the control – 49.68 %. The increase of this indicator in the range of normal values indicates an increase in the rate of metabolic processes in the liver. At the age of 28 days the bird experimental groups the quantity of urea in serum was lower in the control group.
Keywords: broilers, microbiological preparations, diet, hematological blood parameters, total albumen, hemoglobin, feed additives.
