Prevention of subclinical forms of hypocalcemia and ketosis in dairy cows

Abstract

Obtaining livestock products from healthy livestock is the main goal of the entire livestock industry. The intensification of animal husbandry is accompanied by the active introduction of modern technologies for keeping, feeding and exploitation. Against the background of technological stress factors in cattle, there is a decrease in the duration of productive use, which is due to high morbidity against the background of a decrease in the immune response. The economic losses associated with postpartum illness are forcing professionals to make more informed decisions about prevention and treatment.It is for this reason that the purpose of our study was to study the spread of postpartum diseases in highly productive cows and the prevention of metabolic disorders in newborn cows with PS-2, Prevention-N-E and PDE with E-selenium.In the course of the analysis of morbidity, it was revealed that after calving cows, obstetric and gynecological pathologies are most often recorded: mastitis (26.5%), endometritis (24.5%), subinvolution of the uterus (24.15%), retention of the placenta (7.15%), ovarian diseases (17.45%). Against the background of inaccuracies in feeding during the transition period, the animals have a deficiency of calcium, glucose, phosphorus, as well as an excess of reference values in terms of aminotransferase metabolism. Against the background of immunocorrection of the body in cows of 1,2 and 3 experimental groups, an increase in the level of calcium, in contrast to the control, is noted by 0.22 mmol / l - PS-2, 0.27 - Prevention-NE and 0.24 mmol / l - PDE+ E-selenium. Similar dynamics was observed in the level of glucose in the blood of cows of the experimental groups, exceeding the control values by 22-38%.The use of PS-2, Prevention-N-E and PDE with E-selenium made it possible to reduce the risk of latent ketosis and hypocalcemia by 2 times, compared with animals that did not receive prophylaxis.The obtained results of biochemical studies prove the stimulating effect of biological products on the mineral metabolism of the body and the absorption of macronutrients.
