The paper demonstrates the results of applying some doses of probiotic specimen “Propionovyy” when feeding broilers. Propionovyy specimen was developed by the staff of the Laboratory of Microbiology of the department “Siberian Research Institute of Chemistry” of Federal Altai Center of Agricultural Biotechnologies. It includes multi strain propionate of Propionibacterium freudenreichii type taken from the Siberian collection of microorganisms. The scientific and economic experiment was conducted at the poultry farm of LLC Kuzbass Broiler in the Kemerovo region. The researchers arranged four groups of broiler chickens; each group contained 198 broilers. The control group received a basic diet without probiotics. In the experimental groups, different dosages of Propionovyy specimen were added to the main diet instead of feed antibiotic. The experiment explores the effect of “Propionovyy” specimen on livestock farming and physiological parameters of broiler chickens. The following indicators were considered: live weight, absolute and average daily gain of live weight, poultry liveability, feed costs per 1 kg of gain, morphological and biochemical indicators of blood at the age of 28 and 39 days. The researchers observed the chickens of experimental groups who received probiotic specimen “Propionovyy” and found out an increase in live weight by 0.49-1.94%, an absolute and average daily increase of up to 2.00%. The safety of the chickens receiving the probiotic was increased by 1.00-2.02% compared to the control group. Hematological parameters of blood in chickens of all groups varied within the limits of physiological standard that testifies to the healthy physiological condition of the poultry. The authors found out the decrease of glucose and cholesterol concentration in blood serum in the experimental groups. According to the research results the authors elaborated the appropriate and efficient dosage of “Propionovyy” specimen, rendering the greatest positive effect on productive qualities of poultry and reducing expenses of forages on 1 kg of growth on 0,05 kg.
