EFFICIENCY OF THE PREPARATION BASED ON THE ESSENTIAL OIL OF ABIES SIBIRICA IN COMPLEX THERAPY OF RESPIRATORY DISEASES OF YOUNG CATTLE
Currently, one of the promising areas in the development of preparations used to prevent and treat respiratory diseases of young cattle is the development of preparations based on fir essential oil. A natural preparation of Aerosan-P was developed in Rosvetfarm Co., Ltd (Krasnoobsk, Novosibirsk region), the main active ingredient of which is the Abies sibirica L. essential oil. Because of the active substance, the drug has a beneficial effect on the mucociliary apparatus of the respiratory system, and has a mucolytic action, promotes energy metabolism and improves appetite. In the present paper, the results of the study of the therapeutic efficacy of the treatment of respiratory diseases of young cattle are shown, when Aerosan-P is included in the treatment. It was found that the inclusion of the preparation in the treatment regimen at a dose of 2 ml per animal once a day, for 7 days, has showed 95 % efficiency and promoted acceleration of the animals' recovery in the experimental group by 2.46 days relative to the control group. Recovering of animals was characterized by an improvement in the general condition, decrease of rectal body temperature, normalization of respiratory activity and heart rate, disappearance of rales, dyspnea and cough. At the same time, the content of leukocytes, erythrocytes, hemoglobin and ESR was normalized to the level of a healthy animal. The economic efficiency of the experimental scheme with the inclusion of the Aerosan-P preparation was 2.02 rubles. for 1 ruble of costs, which is 1.91 rubles. more than the treatment of the control scheme. In the result, the scheme including Aerosan-P preparation has a high therapeutic and economic efficiency and contributes to faster normalization of clinical and hematological parameters.
