Methods of correcting stress adaptation of young cattle

Abstract

For the first time in the conditions of the Magadan region, studies were carried out to study the effect of a new non-traditional feed additive (FA) of plant origin, consisting of kelp flour (Laminaria), lichen - alpine cladonia (Cladonia alpestris) and Icelandic cetraria (Cetraria islandica), introduced into the diets of mixed young cattle of meat direction, on morphological and biochemical parameters of blood, as well as the general resistance of young animals. It was found that the inclusion of a component feed additive in the diets of calves of the dairy period affects their growth and development, improves the physiological state, resistance of gobies in the experimental group, in comparison with the control one. This is reflected by an increase in the protein content in the blood serum of calves of the experimental group by 9.8 g / l (14.37%), hemoglobin by 0.2 g / dl (1.86%), lymphocytes by 1.2%, and a decrease in the content of leukocytes by 1.02 thousand / μl (9.57%) relative to young animals in the control group.
