Erythron and protein system in piglets blood under stress influence

Abstract

The article presents the results of research on the development of adaptive syndrome in the system of erythron and protein of piglets at the effects of weaning stress. After one (anesthetic stage) and seven days (beginning of G.Selle's resistance stage), after the echoing, the adaptation of the erythron system was shown by a decrease in the number of red blood cells on the contrary of increasing the mean corpuscular volume and hemoglobin indicating the inhibition of erythrocytosis with simultaneous macrocytosis, and a decrease in mean Corpuscular hemoglobin concentration for 14.0–13.0 % that indicated hypochromia. In these stressful periods, the catabolism of protein substrates was discovered, the redistribution of albumins between blood and tissues in the form of a decrease in the total protein content by 6.1–7.1 % due to albumin by 14.8–10.0 %, and the deficit of the humoral link of the immune response due to reduction of γ-globulins by 29.9–18.7 %. In the later stages of the resistance stage (after 20 and 60 days after weaning), there was a stabilization of erythrocytic indices and the development of anisocytosis in the form of an increase in red cell distribution width by 19.0 %, with a simultaneous decrease of 6.1 % of the total protein content, redistribution of its fractions in the side of the growth of γ-globulins by 18.4 %. A practical, prolonged way of preventing disorders in the erythron and protein of extramarital piglets was feeding the additive “Biovir”, which stimulated the intensity of oxidative-reducing processes and the exchange of proteins.
