Rabbits' erythrocytes response to short-term industrial stress

The aim of the study was to investigate the morphological response of erythrocytes in rabbits to industrial stress caused by the rearrangement of animals during its correction with a probiotic. The object of the study was outbred adult male rabbits kept in the educational vivarium of the Far Eastern State Agrarian University of the Amur Region in Blagoveshchensk. Two groups of animals were formed with 5 individuals in each according to the principle of pairs-analogues. Five days before the rearrangement and the same number of days after it, the rabbits of the experimental group were fed the probiotic preparation Intestevit-TM at the rate of 0.5 g per head. Before the experiment, a control blood sample was taken. The experiment was carried out for seven days. The industrial stress factor was the rearrangement of rabbits. Blood was collected on the first, third and seventh days according to standard laboratory research methods. Blood was analyzed on a hematology analyzer Mindray BC-2800 Vet. The obtained data were subjected to variation statistics processing. The use of the probiotic preparation Intestevit-TM in a dose of 0.5 g orally allows stabilizing the total content of red blood components already on the first day after the regrouping of rabbits. Without correction of the adaptive abilities of rabbits in the specified period, normalization of these indicators is observed only on the seventh day. Morphological assessment of the state of erythrocytes by shape, degree of intensity of their color, formation of sludge and other deviations in animals that received the probiotic drug Intestevit-TM indicates their earlier adaptability (1-2 days) to changes in living conditions after regrouping, in contrast to animals in the control group (up to 7 days and more).
