The analysis of infectious and invasive diseases of horses spread in the Republic of Sakha (Yakutia) was carried out. The data from the reports of the Department of Veterinary Medicine and the Republican Veterinary and Testing Laboratory for the period 1986-2017 was used. The main diseases of horses bred in herds in the conditions of Yakutia, which cause significant economic damage, are rhinopneumonia, salmonellosis, leptospirosis, horse strangles, strongylatoses and parascaridosis. These diseases reduce actual foal crops by 20-40% due to infectious abortions. Economic damage per 100 mares may amount to 800-1600 thousand rubles per year. Salmonellosis abortion was registered in 143 settlements of 22 districts, leptospirosis - in 199 settlements in 25 districts. Incidence of horse strangles accounts for 62%, mortality rate being from 4 to 22%. Circulation of the rhinopneumonia virus was noted in 99 settlements of 16 districts. The prevalence of strongylatoses and parascaridosis is 100 and 64.7%, respectively. The greatest concern for horses is caused by 6 species of gadflies of the genus Hybomitra. Species composition of bloodsucking mosquitoes of Central and Western Yakutia is represented by 14-15 species. The epizootic situation in the Republic of Sakha (Yakutia) with salmonellosis abortion, rhinopneumonia, leptospirosis, horse strangles, strongylatosis, parascaridosis and entomosis remains tense. It is necessary to develop and implement plans for the prevention of infectious and parasitic diseases using diagnostic stodies, effective vaccines, anthelmmtics and probiotics. |
