An acute problem in industrial turkey breeding is maintaining a high immune status of birds in order to increase the safety of the stock, productivity and,  accordingly, the quality of meat. At the same time, the most important factor is proper bird feeding arrangement. In recent years, there has been a tendency  in industrial turkey feeding to use various products that improve the birds’ digestion physiology which can replace feed antibiotics. The search for biologically  active substances that can stimulate development of the natural microflora of turkeys in order to suppress pathogenic bacteria by increasing the number of  bifido and lactoflora are of great interest in science and practice. Various probiotic products have similar properties. The aim of our research was to study the  effect of Profort probiotic feed additive on meat productivity of turkeys of Hybrid Converter cross. A production experiment was carried out on turkeys of Hybrid  Converter cross. Control slaughter of turkeys was carried out at the age of 98 days. Ten birds were selected from each group. The birds were fed for 60 days, the eed additive was given at a dose of 1 kg per 1 ton of the combined feed. Poultry processing and anatomical and morphological analysis of the carcasses were  carried out in the laboratory of the research center of the Federal State Budgetary Scientific Institution “All-Russian Research Veterinary Institute of Pathology,  Pharmacology and Therapy”. The results were statistically processed using Statistica v6 program . Studies showed that application of Profort feed additive  had a positive effect on meat production of turkeys. The superiority of the experimental group was clearly expressed in all the studied parametres. The results  obtained allow us to recommend Profort probiotic feed additive for use in turkey breeding in order to increase productivity
