Health conditions of calves and strategy for prevention of early postnatal pathology

The neonatal period is characterized by a state of unstable equilibrium of the basic functions of the body. The search for new means to manage the adaptation processes of newborns is an actual task for effective animal husbandry. To assess the status of Holstein calves, classical methods of blood research with the use of automatic hematological and semi-automatic biochemical tests BCE-90Vet and BioChemBA were used. In the early postnatal period, calves were diagnosed with physiological hyperalbuminemia, bilirubinemia, leukocytosis and hypoglycemia. According to the scheme adopted in husbandry, the calves of the control group received dairy feed, the experimental group received EnteroZoo sorbent at a dose of 0.05 g / kg weight once a day, two hours after the last feeding for 21 days, as a supplement to the main diet. A laboratory research of blood of calves of the control group showed a decrease of total protein, albumin, total bilirubin, total calcium, ALT, alkaline phosphatase, erythrocytes and hemoglobin by 17.1%; 37.4%; 83%; 9.9%; 7.9%; 6.2%; 49.5% and 63.4%, an increase in urea concentration by 19.4%, glucose by 38.4%, inorganic phosphorus by 30.4%, leukocytes by 8%. Anemia was detected, simple dyspepsia was reported in eighty percent of animals, which turned into a toxic form in two animals with the subsequent development of enteritis. In calves of the experimental group, a similar increase in the level of globulins, urea, glucose, inorganic phosphorus, and a decrease in albumin, total bilirubin and alkaline phosphatase activity were noted. Against of the use of enterosorbent, the concentration of total protein in calves did not change. The content of erythrocytes increased by 12.2% and the content of leukocytes decreased by 32%. Consequently, during the period of early postnatal adaptation of calves, EnteroZoo showed an antidiarrheal effect, stimulated the excretion of metabolites, without having a negative effect on the absorption of nutrient and biologically active substances.
