Physiological, biochemical and morphological parameters of the blood of newborn calves after the application of sodium nucleinate to dоwn-calving cows

The features of the activity of organs and systems in newborn animals are determined by the degree of their functional maturity in the early postnatal period of ontogenesis. The birth of resistant offspring and the production of colostrum with a high level of immunoglobulins and their broad antimicrobial specificity is one of the priority tasks in modern animal husbandry. The aim of the research was to study the effect of Sodium nucleinate 0.2 % on colostral immunity and the development of natural resistance in newborn calves. The work was carried out on the basis of the APC «Nizhegorodets» of Nizhny Novgorod region. In the course of the experiment, the titratable acidity of colostrum, the level of total immunoglobulins was determined, morphological and biochemical analysis of the blood of newborn calves was carried out on the second and tenth days after birth. As a result, there was an increase in the number of leukocytes, total protein, albumin and gamma globulins in the blood of calves from the experimental group, as well as a higher level of immunoglobulins and titratable acidity of colostrum of cows in the experimental group.
