Fleming’s discovery of the first antibiotic in the forties of the last century was the real sensation and it was accepted in medicine and veterinary science as a “wonderful remedy” of the 20th century. In fact, many illnesses, which had been considered fatal for long centuries, became successfully curable. Then antibiotics were added to the forage of animals. Thus it became clear that except medical effect antibiotics influenced positively animal’s growth and development. However some years later it was established that many microorganisms developed protection mechanisms to antibiotics, a particular resistance and the efficiency of antibiotics thereby decreased sharply. Consequently in recent years an intensive searching of alternative replacement of antibiotics in animal husbandry and veterinary medicine has been conducted all over the world, including Russia. One of the real directions is the probiotics which represent biomass of bacteria in a vegetative or sporous form. They possess with well-expressed antagonistic activity to pathogenic and opportunistic microflora. The new probiotic antibacterial preparation Sporobakterin is the most effective one at cultivation of young growth of animals according to the producer (JSC “Bakoren”, Orenburg). We made research and production experiment on test of a Sporobakterin at cultivation of calves at the request of the specified scientific institution. During the conducted experimental studies it was established that this preparation promotes increasing of quantity of erythrocytes, leukocytes, hemoglobin in blood at experimental animals and in blood serum — the level of the general protein, albumine, scale-globulins. Besides Sporobakterin promotes increasing of an average daily gain of live weight and safety of calves.
