Abstract. Intensification of modern pig farming requires optimal maintenance of the physiological state of the pig population. The degree of intensity of metabolic processes is significantly reflected in blood parameters. Many diseases and conditions are associated with inflammation and oxidative stress, which mainly occurs due to an imbalance between the formation and neutralization of “prooxidants”. The purpose of the study was to assess animal welfare through the study of the parameters of serum and whole blood of young pigs. Much attention was paid to the determination and relationship of the total amount of water-soluble antioxidants (TASWA) with blood metabolites, hematological and mineral blood parameters in the first period of pig fattening. Materials and methods. The whole blood and its serum from hybrid pigs (in the first period of fattening) were studied at the automatic biochemical analyzer in the Ernst Federal Research Center for Animal Husbandry. Scientific novelty. For the first time in the work, the TASWA indices of the blood serum of young pigs were measured (the average value was 16.39 ± 3.03), on the basis of which an attempt was made to evaluate the antioxidant status of fattened young pigs in comparison with the biochemical, hematological and mineral indices of the blood. Results. The study revealed a relationship between TASWA and albumins, erythrocytes, hemoglobin, iron and chlorides. It is important to emphasize that the antioxidant status in a living organism is assessed by the total antioxidant activity of both endogenous and exogenous antioxidants, i. e. the TASWA index is an integral indicator of the antioxidant status as a whole. Regular biochemical blood tests are required, which help to track the dynamics of the body’s vital functions, identify deviations, some pathological conditions, and control the effectiveness of therapeutic and preventive measures.
