title: [The present epizootological situation in intensively bred cattle in relation to the morbidity and mortality of calves during their rearing].
abstract: The rise and mass incidence of intestinal and respiratory infections in calves kept in large herds depend on a joint influence of infective agents and numerous endogenous and exogenous factors, mostly with non-specific action. Therefore, purely medical approach fails to provide efficient prevention. Detailed epizootological analysis is needed for taking actual measures; the analysis should concern potential respiratory and intestinal pathogens and should also cover the persistent infections such as IBR, BVD-MD and others. The immunological profile of herd, very unfavorable with the high culling rate, will improve as a result of the introduction of a purpose-oriented vaccination programme, higher level of colostral nutrition, and separate rearing of calves, isolated from the dams, in calf houses managed by the all-in-all-out system.
