THE INFLUENCE OF SEASONS, ENVIRONMENTAL AND TECHNOLOGICAL FACTORS ON ERYTHROCYTE SEDIMENTATION RATEOF COWS
Introduction. Erythrocyte sedimentation rate (ESR) is a classic method of clinical laboratory diagnostics. This method has stood the test of time. ESR in some cases is quite sensitive and informative response. It shows the development of pathological processes in the body rather than the body temperature or leukocytosis. ESR is not specific to a disease, but it changes always an indicator of the presence of the pathological process in the body.
The goal of the work. To study the impact of seasonal and environmental factors on ESR.
Materialsandmethods. Research conducted at two farms: agricultural private enterprise (SHPP) “Majak” in Sarny district, Rivne region, located in the contaminated zone (level of radioactive contamination – 1–15 Ci / km2) and in Lesi Ukrainka limited liability company (LLC) in Drohobych region of Lviv oblast, situated on relatively clean environmental area. The study was conducted in 3 seasons (during the grazing period, at the beginning and at the end of stall period).
Blood for the study was from animals before feeding from the jugular vein, according to the rules of aseptic and antiseptic. ESR determined in capillaries Panchenkova at 45°.
Results of research and discussion. The results of the study seasonally erythrocyte sedimentation rate (ESR) of cows from farms located in different ecological zones. Established that the ESR is an objective indicator of adverse reactions to the combined effect of negative factors such as seasonal and environmental. The response was very slow in all periods of the study, but especially in the fall of cows are kept on the farm, located in the contaminated area.
ESR is not specific to a disease, but it is changing indicating the pathological process in the organism. ESR blood of experimental group of animals from both farms was slow. At the end of the grazing period ESR does not fit into the limits of the physiological norm.
In order to eliminate the negative impact of radionuclide stress on cows in winter stall period. ESR in the experimental group of cows from farms located in the contaminated territories decreased, while the control group remained almost unchanged. ESR slowdown in the experimental group of animals may indicate a recovery of erythropoiesis.
Conclusions and prospects for further research. Established that the ESR is an objective indicator of adverse reactions to the combined effect of negative factors such as seasonal and environmental. Slowdown of ESR indicated on that of the farm.
Further research will be aimed at a more in-depth study of the impact paratypovyh factors on the functional state of animals.
