Abstract
The aim: to determine the effectiveness of aerosol prophylaxis of nonspecific bronchopneumonia in calves by using a complex of biogenic compounds of macro- and microelements and plant immunomodulator Echinacea in the form of the drug Kalfmin on production indicators.
 Materials and methods. The research was conducted in the farm "Podilsky owner 2004", v. Velyka Medvedivka, Shepetivka district, Khmelnitsky region on black-spotted calves, which were in the risk group for bronchopneumonia, taking into account certain technological components, namely – stress due to regrouping of animals, some adjustment of their feeding rations, some excess concentration of livestock animals in groups and other factors.
 Results. The results of studies indicate a high therapeutic efficacy for the use of the drug "Kalfmin" group aerosol method in the treatment of patients with calf bronchopneumonia, as this drug enters the body in the same way as pathogens. It was found, that 40 % of calves in the control group, which did not receive preventive measures, have clinical signs of bronchopneumonia, and 10 % of cases were fatal. At the same time, signs of bronchopneumonia were found in only 10 % of calves in the experimental groups, who received aerosol prophylaxis according to the experimental scheme; their course was much easier and without fatal consequences.
 Conclusions. Prevention of bronchopneumonia in young cattle should be comprehensive and aimed at eliminating violations of the technology of keeping, feeding and increasing the resistance of animals. Group aerosol prevention of nonspecific bronchopneumonia in calves using the drug Calfmin in combination with the plant immunomodulator Echinacea is a more promising and effective method of preventing this pathology compared with the use of turpentine, lactic acid and chlorinated lime. The use of the drug Kalfmin in combination with Echinacea is characterized by 1.60 time’s higher efficiency and 1.70 times shorter period of prevention of animals
