The study was conducted on young Termon White rabbit analogues from the 35th to the 65th day of life. Rabbits were kept in a separate room of an industrial rabbit farm, where conditions of elevated environmental temperature ranging from 28.9 to 30 °C and relative humidity from 80 to 87.5% were created. For the study, a control group of rabbits was formed, which were kept on a standard balanced granulated feed produced on the farm and water ad libitum. It was found that the most pronounced effect on changes in hematological blood parameters in rabbits was observed when calendula was added to the diet. Creeping thyme, unlike calendula, did not affect some hematological parameters, but had a similar effect on certain blood parameters of animals. The effect of lavender was marked by less pronounced changes compared to other applied medicinal herbs with respect to the control, which was manifested by an increased level of erythrocytes, hemoglobin, hematocrit value, average hemoglobin content in an individual erythrocyte, average platelet volume, and a decrease in the absolute content of leukocytes and lymphocytes on the 50th and 65th days of the experiment.
