The rabbit organism has physiological and biological features that stipulate certain requirements for the realization of their genetic potential, which is not always possible to fully ensure in today’s production realities. In particular, such peculiarities as growthiness and prolificacy, predetermine the intensive development of the rabbit organism in the early stages of the postnatal period of ontogenesis. The intensification of technological processes in rabbits leads to the search of such feed additives that have adaptogenic influence on the body of rabbits. In the article the results of hematological blood examinations of rabbits of the Hyplus breed of two-month – old against the background of the use of the biologically active feed additive «Humilid» are presented. The control and experimental group of animals of 8 in each was formed by the principle of similar groups. The rabbits of both groups were in the same feeding and holding conditions. During 21 days to the rabbits of the experimental group were given Humilid at a rate of 5 mg/kg individually, together with water. The blood was collected from the rabbits on an empty stomach, at the beginning of the experiment and at 14-, 21-, 35-days of the examination. In the blood an amount of leucocytes and erythrocytes, haemoglobin level, hematocrit were determined, the leukocytic formula have been derived. In accordance with the results of the investigations, it was established that the use of Humilid for two-month-old rabbits of the breed Hyplus for 21 days of giving the biologically active additive leads to an increase in hemoglobin level by 13.3 %, the number of red blood cells by 16.0 % and the hematocrit by 15.0 %. Also, adding of Humilid to the diet of experimental animals leads to an increase in the blood of number of neutrophils by 30.7 % and a decrease in the number of eosinophils by 29.0 %. The ability of Humilid to influence the innate level of immunity by increasing the number of neutrophils on the one hand, and the ability to activate erythrocytopoiesis on the other hand, determine the use of Humilid as an adaptogen.
