The Effect of the Drug “Enterocol” on the Humoral Factors of Calf Body Resistance

As world experience shows, of particular importance in the prevention and treatment of gastrointestinal diseases of young animals is replacement therapy, aimed at restoring intestinal biocenosis through the regulatory injection of live bacteria representing the normal intestinal microflora. Currently, the veterinary service has a sufficient number of domestic and imported probiotic products of various species composition, intended for the prevention of gastrointestinal diseases of young animals and birds. However, monitoring of the probiotic market shows that the vast majority of developments are not in demand by practice. This circumstance gives grounds to assume that the approach to the development of probiotics should be based on the study of many parameters, including, first of all, a comprehensive assessment of the properties of microorganisms – probionts. The article presents the results of studying the effect of “Enterocol” from the strain E.coli 64G on the total amount of protein, quantitative and qualitative content of immunoglobulins in the blood serum of newborn calves. It was found that feeding off of the newborn calves with “Enterocol” helped to increase the concentration of total protein and immunoglobulins of all classes in the blood. The authors of the study came to the conclusion that the degree of the above increase depends on the dose of the drug given.
