PATHOLOGICAL CHENGES IN THE ORGANISM OF PIGLETS IN THE PRODROMAL STAGE OF COLIBACTERIOSIS
M. Srypka, I.Zapeka
Abstract. Balanced diets by micronutrients has a significant impact on morphological and functional parameters that characterize the state of cellular and humoral immunity of animals. Excessive intake of animal copper, iron, cobalt leads to intoxication, which contributes to the development of secondary immunodeficiency, resulting in an increased rate of morbidity and mortality of piglets, dairy period at colibacillosis. In the prodromal stage of disease, there is a flatulence of the stomach and intestines, the parenchymal organs – the signs of protein dystrophy in the lymph nodes of the cranial mesenteric lymph center and spleen – congestion, edema. At colibacillosis due to high quantities of micronutrients noted a thinning of the wall of the jejunum, villi length is reduced reduced by 54,39 %. The area of lymphoid nodules on 80,84 % less in relation to the control and 84,85 % less in comparison with the animals of the second experimental group. In lymph nodes, the parenchyma of lymphoid nodules weakly differentiated into morphofunctional zones. The area of lymphoid nodules on 44,57 % less in comparison with the control, with the reactive area of the center decreased by 68,82 %.
