Abstract
Bovine respiratory infections occupy the second place in the nosological picture after diseases of the digestive system and cause huge economic damage, which in the Russian Federation, according to our estimates, amounts to several billion rubles a year. Very often, respiratory pathologies in highly productive cows are complicated by wound infections of the distal extremities, which primarily include necrobacteriosis, streptococcosis and staphylococcosis, which also bring economic losses to farms due to reduced animal productivity and culling of highly productive cows.The primary causecontributing to the development of wound infections of the distal extremities in cattle is respiratory infections. According to our long-term observations, all farms where outbreaks of necrobacteriosis were recorded were unfavorable for bovine respiratory infections, such as infectious rhinotracheitis (IRT), viral diarrhea(VD), parainfluenza type 3 (PG-3) and respiratory syncytial infection (RSI). Comprehensive prevention of wound infectionsof the dental extremities of cattle (cattle) should include mandatory prevention of respiratory infections. For complex prevention of mixed infection, we proposed the use of an ECHO (electrochemically activated) solution of neutral anolyte (ANK+) in the form of a fine aerosol in combination with the use of a plant-tissue preparation “Vidoral”, (Patent RU 2,625,022 C2 dated 11.07.2017, copyright holder of the Federal State Budgetary Institution of Higher Education of the UralState Agrarian University ) with immunomodulatory properties.

Summary
Bovine respiratory infections occupy the second place in the nosological picture after diseases of the digestive system [2] and cause huge economic damage, which in the Russian Federation, according to our estimates, amounts to several billion rubles per year. We determined the relationship between these seemingly completely different infections and the mechanism of their association.When the respiratory tract is affected, hypoxia occurs in the animal body, which leads to endogenous intoxication, leading to rumen acidosis [1, 4]. According to our long-term observations, all farms in which outbreaks of necrobacteriosis were recorded were unfavorable for bovine respiratory infections, such as IRT, VD, PG-3 and RSI
