Summary. An analysis of veterinary and sanitary measures against leptospirosis at importing bovine embryos into the Russian Federation, recommendations on leptospirosis risk management provided and not provided in the OIE Terrestrial Animal Health Code, an assessment of risks associated with 3 phases of embryo transfer process in accordance with the OIE Code that determines the final level of risk of disease transmission in the transfer process of in vivo derived embryos are presented in the article. A critical look has been taken at acceptability and relevance of additional measures against bovine leptospirosis when exporting in vivo derived bovine embryos such as vaccination of donor cows, treatment of leptospirosis in donor cows with antibiotics, testing donor cows in case if they are approved for collection of embryos and manipulation with embryos using procedures recommended by the International Embryo Transfer Society. Special attention is paid to the peculiarities of leptospirosis in large horned cattle versus other susceptible species, expressed in a high probability of carring Leptospira borgepetersenii serovar Hardjobovis and Leptospira interrogans serovar Hardjoprajitno, to the imperfection of laboratory diagnosis methods at the individual level and to the need for further studies of embryonic manipulation techniques using procedures of washing embryos in media with antibiotics as the most promising. Based on the results of the analysis and evaluation, as an additional measure, taking into account the current level of knowledge on the problem, treatment with an antibiotic with the proven efficiency of the drug against the causative agent of leptospirosis is justified and recommended for donor cows.

Keywords: large horned cattle, leptospirosis, «in vivo» bovine embryos, donor cows, veterinary and sanitary measures, import, international trade, risk analysis, risk management, terrestrial animal health code.
