The effect of the probiotic feed additive "Healthy calf" on the clinical and morphological parameters of the blood of calves with bronchopneumonia

The aim of the study was to establish the degree of influence of the feed additive "Healthy calf" on the normalization of clinical and morphological blood parameters, when it was introduced into the treatment regimen for bronchopneumonia in calves. The production experience was carried out in a farm that was safe for diseases of infectious etiology. The experiment involved 30 black-and-white calves aged 20 to 30 days, of which three groups were formed. The first (control) intact group (n=10) included clinically healthy animals. The second (n=10) and third (n=10) experimental groups included animals with a clinical manifestation of nonspecific catarrhal bronchopneumonia. The animals of the second and third groups were prescribed a treatment regimen based on antibacterial therapy. They were prescribed Streptomycin sulfate as an antimicrobial drug, at a dose of 10.0 mg / kg of body weight twice a day until full recovery. At the same time, during the entire experiment, as an addition to the above treatment regimen, animals of the third group were given oral probiotic supplement "Healthy Calf". Blood samples to determine the values of its main clinical and morphological parameters were taken at the beginning of the experiment, as well as on the seventh and 14th days of its conduct. Blood tests were performed using generally accepted techniques. It has been established that the use of probiotic feed additive "Healthy Calf" in addition to treatment regimens for catarrhal nonspecific bronchopneumonia can reduce the degree of anemia and the intensity of the inflammatory process.
