Abstract

The aim of the work was to assess the metabolic processes of newborn calves and the formation of their colostral immunity after the application of biological preparation «Ribotan» to their mother cows 3-9 days before calving. In calves on the 2nd day of life, a decrease in the content of lactic acid by 45%, as well as a decrease in the lactate/pyruvate ratio by 17,9% was noted. An increase in superoxide dismutase activity by 50% and a decrease in the level of malondialdehyde by 25,8% were also noted. The result of the normalization of the metabolic processes state of newborn calves was a decrease in endogenous intoxication of their body, which led to an improvement in clinical and physiological parameters, including a confident standing position for 11,2 minutes, and also a sucking reflex appeared faster by 13,6 minutes. The level of total serum immunoglobulins increased by 63%. A higher level of colostral immunity led to a decrease in the incidence of omphalitis and enteritis form of escherichiosis in calves by 2-3 times in the early postnatal period of ontogenesis.
