The intensification of animal husbandry prompts producers to use modern technologies that are safe for humans and promote the welfare health animals. Despite long time spent studying effectiveness probiotics, questions regarding optimal composition period rational probiotic feed additives (PFA) young animals, in particular as alternative antibiotics remain relevant. purpose study was evaluate effect a additive on clinical biochemical parameters healthy calves (Black-and-white breed, 1 day year age) from different physiological groups preventive efficiency. PFA (Bacillus subtilis Bacillus licheniformis) at all stages growing had positive growth indicators, increased live weight animals average daily gain, allowing more efficient feed, mitigation production stress obtaining greater profits intensive breeding, sales ecological products, reduction costs veterinary services. Thus, it is advised neonatal formation intestinal microbiocenosis; age 1-2 months: order correct immune reactivity; 3 months - improve processes rumen formation. PFA, additionally supplemented with Sacharomyces serevisiae, can reactivity old calves; improved months; prepared heifers mating 12 months. obtained results experimentally substantiated probiotics within framework WHO Global Action Plan Anti­microbial Resistance has been proven prevention diarrhoea and/or bronchopneumonia result even one calf, allowed avoiding least 4-6 days antibacterial therapy reduced risks antibiotic-resistant bacterial clones, zoonotic agents.
