Purpose. To investigate the effect of feed supplements "NUPRO" and "BIO-MOS" on basic hematological indices of the carp (Cyprinus carpio L.). Methodology. Hematological studies on the effect of feed supplements "NUPRO" and "BIO-MOS" on the indices of age-1+ Nyvkiv scaly intrabreed type carp have been performed according to the generally accepted methodology. Experiments were conducted in the conditions of DPDG "Nyvka" of the Institute of Fisheries of the National Academy of Sciences of Ukraine. Fish ponds with an area of 0.5 hectares stoked with age-1 carp where used for the study. The stocking density was 3.0 thousand fish / ha. Findings. The study showed that feeding of age-1+ carp with a balanced PKC 111 - 2/2/4 feed formula with the addition of 5% feed supplement “NUPRO” and 2% “BIO-MOS®” in comparison with the control group, which was fed with the same feed formula but without feed supplement, resulted in the improvement of basic hematological parameters in the experimental fish. These preparations had a positive effect on leukocyte formula and stimulated phagocytic activity of neutrophils, which greatly increased the immune status of the carp. At the same time, the hydrochemical parameters in the experimental ponds were within the normal limits and the temperature regime was optimal for growth and metabolism of carp organism. Thus, it can be recommended to introduce these feed supplements to the diet of age-1+ carp to enhance the immune status of the organism, which in turn will result in higher yields from growing and additional weight gains of fish. Originality For the first time, an analysis of the effect of feed supplements "NUPRO" and "BIO-MOS" on hematological parameters of age-1+ Nyvka scaly carp was performed. Practical value. In order to increase the immune status of the carp, it is proposed to use feed supplements "NURORO" and "BIO-MOS" when rearing age-1+ carp/.
