Laboratory of Nutritional Physiology & Feeding

Research Activities

Research Topics

The research activity of the Laboratory is focused on:

  • The systematic investigation of nutritional physiology of farm animals, such as ruminants (cattle, sheep, goats), monogastric herbivores (ungulates, rabbits), monogastric omnivores (pigs, poultry) and others, in combination with the development of Biotechnology and Molecular Biology

  • The study of the properties, chemistry and technology of various feedstuffs

  • The detailed study of the effects of nutrients on metabolism and various physiological functions of the animal body, so as to protect animal health and optimize their performance

  • Improving product quality through supplementing diets with bioactive compounds (omega-3 fatty acids, conjugated linoleic acid-CLA, antioxidants, etc.) that promote human health

  • Reducing the environmental pollution caused by animal farming (organic farming, grassland management, reduced methane emissions and excretion of minerals, such as N, P, etc.)

  • The study of the interactions between genes and nutrients

  • Promotion, dissemination and application of scientific knowledge to optimize the effectiveness of nutrition in practice (through counselling and education of people, involved directly or indirectly to animal nutrition)

  • Understanding gut function and health interactions with animal performance

To achieve the above, the Laboratory attends closely the ongoing international developments in science and technology on Animal Nutrition. In order to ensure the quality of the research, the Department constantly updates all kinds of teaching and research material and equipment (books, journals, magazines, computers, software, analytical techniques, analytical devices, scientific instruments, etc.).

Finally, the Laboratory is working closely with public and private institutions (Ministry of Rural Development and Food, Research Institutions, prefectural and local administration, industries, businesses, corporations, private producers, etc.), so as to address and solve various theoretical and practical problems, thus maintaining an essentially creative and fruitful relationship between University and productive society.
