COMPARATIVE ANALYSIS OF IMMUNOMORPHOLOGICAL BLOOD INDICATORS OF HYPOTROPHIC PIGLETS

Abstract

The article presents the data on immunological and morphological blood indicators of the newborn piglets. In the experiment, 20 sows of the 3rd-4th farrowing and the offspring obtained from them were selected. During the farrowing period, the piglets underwent clinical examination and weighing. The animals that did not reach 900 g were counted as hypotrophic piglets, the animals over 900 g – normotrophic, respectively. The first group (n=10) - hypotrophic piglets, and the second (n=10) - normotrophic piglets. Morphological blood examination in the hypotrophic piglets showed a decrease in the concentration of hematocrit and hemoglobin. The mean cell hemoglobin (MCH) assumed the values at the upper limit of the physiological norm, while the mean cell hemoglobin concentration (MCHC) in the normotrophics was by 17% higher than in the hypotrophics (p<0.05). The red cell distribution width (RDW) in the normotrophics was by 2.3 times higher than in the hypotrophics (p<0.05). When studying the immunological status of piglets, it was noted that the serum lysozyme activity in the hypotrophics was by 16% lower than in the normotrophics. The PAL in the normotrophics was 79.6±1.58, which was by 4.8% higher than in the hypotrophics (p<0.05). The PhN in the hypotrophics was by 11% less than in the normotrophics (p<0.05). The phagocytic index in the normotrophics was by 10% higher than in the hypotrophics (4.68±0.16) (p < 0.05). The PR of the normotrophics was by 1.5 times higher than that of the hypotrophics and was 3.03±0.2 (p<0.05).
