摘要:The results of research in some cases allow to judge the change in the functional activity of the studied organs after the use of the preparation. The obtained factual material significantly supplements the information about the biological properties of the propolis water-alcohol emulsion. In practical veterinary medicine, the results of research can be taken into account when prescribing propolis for therapeutic and preventive purposes. Thus, 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 young pigs and pigs of the experimental groups. The height of this intestine villi in young pigs of the experimental group is 280.97 ± 3.37 microns, and in the control group - 193.89 ± 2.66 microns (p< 0.001). In pigs treated with the preparation, the villi also have a higher height - 256.89 ± 1.62 microns compared to 163.96 ± 0.61 microns in the control group. In young pigs and pigs of the control groups, the shape of the ileum villi is finger-shaped or bottle-shaped, and in animals of the experimental groups their forms are more differentiated - bottle-shaped, leaf-shaped and dome-shaped. This will allow store pigs receiving propolis preparation to better absorb the nutrients of the diet and gain weight faster. The research results are of interest to researchers developing propolis preparations for oral use.
