Hematological parameters of pigs of Poltava meaty breed of different genotypes

The development of new modern systems of breeding farm animals should be based on a more complete and effective use of the biological capabilities of their bodies, including hematological parameters. However, it is necessary to establish the hematological status of the selected populations. Taking into account quite noticeable differences in the norms of hematological parameters in pigs, we considered it necessary to compare the clinical status of breeding pigs, as these animals play an important role in the transfer of genetic progress from breeding to commercial herds. The study was carried out on three breed groups: 1) lines and families obtained "in purity", 2) lines and families obtained with "inflow off blood" of the Finnish landrace, 3) lines and families obtained with "inflow off blood" of Precocity meaty breed. The number of erythrocytes, hemoglobin, leukocytes, leukocyte ratio (formula) were determined in the blood. The hemoglobin index (color index) and hemoglobin content in 1 erythrocyte were calculated...
