Abstract

The paper presents the results of morphological studies of internal organs of broiler chickens when using an Anethum Graveolens-based additive in the diet. In the spring-summer period, an experiment was conducted for three groups of broiler chickens. In addition to feed, the 1st experimental group daily received an alcoholic tincture based on Anethum graveolens; the 2nd experimental group – Anethum graveolens seeds; the 3rd group served as the control. After the end of the experiment, the samples of internal organs were taken for histological studies and stained with hemotoxylin and eosin, picrofuchsin according to Van Gieson, Sudan III, according to Weigert, alcian blue. According to the results of the studies, the Anethum graveolens seeds used in the 2nd experimental group did not have a negative effect on the internal organs of broiler chickens. However, the changes were observed in the 1st experimental group using an alcohol tincture based on Anethum graveolens in the diet. At the same time, the data for broiler chickens of the control group were within normal limits.
