Characteristics of variability of blood parameters of pigs of parent breeds used for industrial crossing

Abstract

Relevance. Blood components play an important role in assessing the biological status of breeding animals in accordance with their species, genetic, sexual, exterior, etc. characteristics, which actualizes the problem of finding hematological markers associated with the breed.Methods. The work was carried out on repair pigs of the Duroc breed (n= 30), Yorkshire (n= 90) and Landrace (n= 15), which were selected for reproductive purposes according to the results of the bonitation. The study material was blood, in which morphological and biochemical parameters were determined. The results are statistically systematized based on the mean values ± standard deviation and coefficients of variation.Results. It was found that the variability of the blood parameters of repair pigs is associated with the technological conditions of maintenance and feeding. The number of parameters related to the genotype of the breed is limited. Hemoglobin has genetic determinism, the value of the coefficient of variation of which isCv= 33.61–38.37%, and interbreed differences are 2.39–16.19%. In the leukocyte blood pool, based on the values of the coefficients of variation, the indicator indicators include the number of lymphocytes (Cv= 23.42–27.75%) and monocytes (Cv= 24.09–25.20%). In the lipid spectrum of the blood, the level of triglycerides has indicator properties, the value of the coefficient of variation of which isCv= 165.81–184.02%, and interbreed differences of 25.00–81.82%.
