Leptospirosis and rhinopneumonia are among the most dangerous infectious diseases of horses, which are widespread in breeding farms in many countries of the world with advanced horse breeding. Therefore, it is important to conduct monitoring studies of horses for leptospirosis and rhinopneumonia in order to study the characteristics of the joint course in order to improve the monitoring and control of these dangerous diseases. This article presents studies on leptospirosis in the reaction of microagglutination and rhinopneumonia in the reaction of diffusion precipitation of 295 sera of mares, young animals and stallions. Of these, the blood serum of stallions was 73 samples, young animals – 97 samples, mares – 125 samples. It was found that leptospirosis in the horse farm was hidden in the form of a submunization infection with 100 % gradual destruction of the livestock population. A detailed analysis of the results of the studies showed that in 2018, the activation of the leptospirosis process in horses of horses is due to the progression of such serogroups of leptospira Grippotyphosa, Pomona, Bratislava, Tarassovi, Hebdomatis, Icterohaemorragiae, Sejroe, Canicola. Compared to 2017, the captions increased from 1:100.79 to 1:132.61. Based on these data and the presence of leptospirosis vaccines in Ukraine, it is advisable to administer the Bovis vaccine containing the leptospir antigens Tarasov, Seira (serovar Polonika and Harge), Gebdomatis, Gripotifoza, Ictahemorrhagia. In equestrian conditions, the development of herpesvirus infections of type 1 and type 2 was hidden and seropositivity in the diffusion precipitation reaction tended to decrease. Therefore, it is advisable to monitor 10 % of livestock in spring and fall in order to control the epizootic situation of these infections in this farm. Subsequently, monitoring studies will be conducted on leptospirosis and herpes virus infection of horses after leptospirosis vaccination in order to assess the effect of vaccination on the indicators of co-occurring leptospirosis and rhinopneumonia.
