Peculiarities of enterobiocenosis of newborn calves in the case of mass gastrointestinal diseases

Abstract

An acute problem for farms engaged in breeding and rearing cattle is the morbidity and death of young animals. The main damage to animal husbandry is caused by infectious diseases, the causative agents of which are conditionally pathogenic microorganisms. The composition and sensitivity of microflora to antibiotics affect the choice of empiric antibacterial therapy at the beginning of treatment. The etiologic structure of pathogenic microorganisms and their associations in the cases of mass gastrointestinal diseases in newborn calves and their resistance to antimicrobial drugs was studied on a cattle farm of the Tambov District of the Amur Region in 2016–2020. The authors analyzed antibiotic resistance in calves with the associative course of mass gastrointestinal diseases, caused by Escherichia coli and Proteus mirabilis, for compatibility with antimicrobial agents.
The blood tests results of the study of newborn calves with clinical signs of the digestive system revealed the presence of secondary immunodeficiency disorders. Another approach to the treatment of dysbacteriosis of the animal digestive system is the detection of immune deficiency states, their correction, and prevention.
