CHANGE IN BLOOD BIOCHEMICAL INDICATORS AND INTESTINAL MORPHOMETRIC INDICATORS BECAUSE OF PROPOLIS PREPARATION INCLUSION IN DIETS
The research results in a number of cases allow us to judge about the change in the functional activity of the studied organs after the use of the drug. The obtained factual material significantly complements the information on the biological properties of the aqueous-alcoholic propolis emulsion. In practical veterinary medicine, research results can be taken into account when prescribing propolis for therapeutic and prophylactic purposes, since histological analysis of intestinal sections did not reveal destructive or pathological changes in all compared groups. In the field of zootechnics, the obtained practical material makes it possible to concretize the stimulating effect of the preparation in terms of stimulating the growth of animals depending on the age of pigs. So, as a result of the study, it was found that the most characteristic histological changes in the structural components of the intestinal wall are observed in the ileum of piglets and pigs of the experimental groups. The height of the villi of this intestine in piglets of the experimental piglet is 280.97 ± 3.37 μm, and in the control piglet – 193.89 ± 2.66 μm (p <0.001). In pigs receiving the drug, the villi also have a greater height – 256.89 ± 1.62 μm versus 163.96 ± 0.61 μm in the control group. In piglets and pigs of the control groups, the shape of the villi of the ileum is finger-shaped or bottle-shaped, while in the animals of the experimental groups their forms are more differentiated – bottle-shaped, leaf-shaped and dome-shaped. This will allow young animals receiving propolis to better absorb the nutrients of the diet and gain weight faster. The biochemical parameters of the blood of all animals in the dynamics of the experiment were within the physiological norm. The only exception was a slight decrease below the norm in piglets in the control group with reserve alkalinity of 44.81 ± 0.98 vol. % CO2, observed at the beginning of the experiment. The research results are of interest to researchers developing oral propolis preparations.
