Hematological parameters of pig blood following the use of essential oils

Abstract

Purpose. To study the morphological and biochemical parameters of the pig blood fed with essential oils as part of the protein-vitamin-mineral supplement “Efiprot” in a dose of 150 and 200 g per 1 ton of compound feed. Methods. In the research general scientific methods were used: zootechnical (experiments on animals), physiological (blood tests), statistical (biometric materials), analytical. Results. The use of a new feed component in the rations of experimental groups of pigs leads to an increase in the number of erythrocytes by 2.4-2.8%, leukocytes in the blood of animals of the experimental groups relative to the control indicator – by 1.37-4.94% (Р < 0.001). The leukocyte blood formula of all animals remained at the physiological level, but in the third group, an increase in basophils by 30.64% was observed, as well as a slight increase in eosinophils in both groups – by 9.28-6.55%. According to the research results, the number of platelets was higher in the second and third groups of animals by 1.31-2.9% (P < 0.01). The total protein content increased in the second group by 3.27% (Р < 0.001) and the third one – by 8.62% (Р < 0.001) relative to the control. Indicators of hemoglobin content in one erythrocyte in the experimental groups exceeded the control by 7.82 (Р < 0.001)-12.65% (Р < 0.001). Therefore, according to the results of laboratory studies, the number of albumins increased in both groups by 12.15 (Р < 0.001)-17.15% (Р < 0.001) relative to the control, and the level of bilirubin in the blood of pigs had a slight increase only in the third group – by 7, 41% (P < 0.01). The amount of glucose in the second and third groups increased by 8.84 (Р < 0.001)-6.81% (Р < 0.001). Conclusions. Complex feeding of the protein-vitamin-mineral supplement “Efiprot” with essential oils causes: stimulation of erythropoiesis (increase in the number of erythrocytes) in the blood of pigs and respiratory function of the blood (increase in hemoglobin level); activation of cellular immunity (increase in the number of leukocytes within the physiological norm).
