The laboratory conducts research into the effects of environmental heavy metal-induced chemical stress at the body level. The impact of environmental pollution, including feed and food, on physiological, immunological and biochemical processes in the animal body is in sight. The study of the interaction of heavy metals (Cd, Zn, Cu, Fe, etc.) and vitamins (A, E, C) significantly complements the knowledge about the influence of changing environmental conditions on the body's regulatory mechanisms. Physiological, biochemical, immunological and morphological methods are used in the research.

The main directions of basic research activities:

  • nutrient uptake and transport mechanisms at organ and cellular level; interactions of vitamins and minerals and their influence on assimilation processes;
  • mechanisms of interaction during assimilation between nutrients and toxic elements;
  • assessment of the level of harmfulness of heavy metals in the animal body;
  • the effect of imbalance of prooxidants and antioxidants on the formation of oxidative stress in the body;
  • study of antioxidant and immunomodulatory effects of various nutrients.
