One of the main reasons for the high incidence of young cattle of bronchopneumonia is the low level of the immunological response due to the imperfect immune system of the young organism, as well as the ill-being of livestock farming with one or a number of diseases caused by pathogens related to opportunistic and/or stationary microflora. To obtain a positive result of the treatment of bronchopneumonia, it is necessary to provide the first line of nonspecific protection of the calves’ body, as well as reducing the effects of the infectious and inflammatory stressor on the sick organism. The object of the study was young cattle with florid clinical signs of catarrhal bronchopneumonia. Three groups were formed from the selected calves: control and two experienced. In the control, a generally accepted treatment regimen for bronchopneumonia was used, and in the experiment, electroreflexotherapy was additionally used. Combination treatment of catarrhal bronchopneumonia of calves with the use of electroreflexotherapy contributes to: activation of the inflammatory process, stimulation of specific and non-specific immunobiological surveillance, providing direct and indirect bacteriostatic and bactericidal effects and has some antiadrenergic effect.
