The Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences specializes in research on physiology and animal nutrition. Physiological research focuses on central mechanisms involved in the functioning of animal growth, development and reproduction processes. They also concern the molecular basis of modulation of the activity of the nervous, endocrine and immune systems and their interactions. The main research topic in animal nutrition concerns digestion and metabolism of nutrients in monogastric and ruminant animals. The issues of physiology of nutrition are accompanied by research in the field of feed science, including plant components of compound feed as well as the content and activity of bioactive substances. Those research are also devoted to the role played by symbiotic microorganisms (bacteria and protozoa) inhabiting the gastrointestinal tract of animals – including studies of their species diversity and the ability to break down feed components.

Disciplines: biology, animal husbandry science

Fields of activity:

Animal Physiology: neuromodulatory activity of orexigenic and anorexigenic peptides in the regulation of growth and reproduction processes in the hypothalamus-pituitary axis. Influence of neurosteroids on neurosecretion processes in the central nervous system. Identification of mechanisms forming neurohormonal adaptations in pregnant and lactating female animals. Mechanisms of neuroendocrine regulation of GnRH/LH secretion – influence of endo- and exogenous factors (inflammation, stress, cannabinoids, biogenic amines, neuropeptides). Alternative therapies of civilizational diseases – preclinical studies on animal models.

Animal Nutrition: identification and characterisation of microorganisms present in the gastrointestinal tract in animals. Description of qualitative and quantitative changes of symbiotic microflora and microfauna under bioactive feed constituents. Determination of the role of rumen ciliates in methanogenesis and lipid metabolism. Influence of feed ingredients on digestion processes, immune response in gastrointestinal tract, production and meat quality. Effect of nutritional programming on the health and development of infants and young animals. Alternative therapies of civilizational diseases – preclinical studies on animal models.
