THE OPTIMIZATION OF REPRODUCTIVE AND PRODUCTIVE QUALITIES OF CATTLE BY NATIVE IMMUNOSTIMULANTS
For the improving of reproductive qualities of cows and productive potential of calves offer we biopreparations Prevention-N-Е and PS-2. Both immunostimulants represent a water suspension which contains polysaccharide complex of saccharomyces cerevisiae immobilized in agar gel with benzimidazole derivative. But Prevention-N-Е is a complex preparation and still contains a microbicidal product of macrolide’s group. The biological preparations of group Prevention have a wide range. The applying of Prevention-N-Е and PS-2 reduce a time of separation of the fetal membranes, index insemination, service - period, warns gynecologic diseases in patrimonial and puerperal periods and raised a fertility in the first estrus. It is established that examinees biological products improved hemopoiesis, so were increase erythrocytes, leukocytes and hemoglobin. Besides cows and calves have changes in the leukogram - eosinophilia, shift the neutrophilic nucleus to the right and lymphocytosis. The cows in puerperal period and 180-day calves in experienced groups have a raise of phagocytic and lysozyme activity. These qualitative changes evidence about activization of cellular and humoral factors of nonspecific resistance of cattle . The Intramuscular injections of Prevention-N-Е and PS-2 in the early period of postnatal ontogenesis reduce incidence of respiratory bodies and a digestive tract of newborn calfs, intensify growth and development of young growth. It is worth noting, that Prevention-N-Е approved in the leading cattle breeding enterprises of the Chuvash Republic has more expressed effect compared with PS-2, because Prevention-N-Е Inflicts double blow to pathogen: microbicidal product suppresses an activity of pathogen raising of sensetive to phagocytosis, and biostimulator activates phagocyte increasing its ability to neutralize the pathogen.
