Efficiency application of antibiotics in bronchophemony of calves

To study the effect, preparations of tylosin 50, tetracycline hydrochloride and bicillin 3 on animals with lesions of the pulmonary tract and nasal cavity, calves were used in which, after microscopic and bacteriological studies of samples of washings from nasal cavities, a conditionally pathogenic microflora was identified. The diagnosis examined clinical and epizootic data. Calves, who received antibiotics for preventive purposes, if they were ill, they retained an appetite in a mild form, without dehydration and loss of body weight, the general condition was not violated. Efficacy, simplicity and convenience of the use of tylosin 50 and tetracycline hydrochloride and bicillin 3, lack of the necessary additional treatment, reduction of labor costs and funds for the treatment of calves, was the basis for a good assessment of antibiotics by veterinarians and livestock workers.
