ommercial livestock/animal production is associated

with four major types of stresses, including

environmental, technological, nutritional and internal

stresses, affecting productive and reproductive

performance of animals and their health status. It has

been suggested that at the molecular level most stresses

are associated with overproduction of free radicals and

oxidative stress. Therefore, the development of the

effective antioxidant solutions to decrease negative

consequences of commercially-relevant stresses is

an important task for animal/poultry scientists. One of

such approaches is based on possibilities of modulation

of vitagenes, a family of genes responsible for animal

adaptation to stress. In fact, the vitagene network includes

heat shock proteins (HSPs), thioredoxin system, sirtuins

and superoxide dismutases (SODs) and plays a regulatory

role in most important cellular processes in stress

conditions. Indeed, HSPs, including heme oxygenase-1

and HSP70, are responsible for protein homeostasis

in stress conditions, while the thioredoxin system is

the major player in maintaining redox status of the cell

involved in protein and DNA synthesis and repair as well

as in regulation of expression of many important genes.

Furthermore, sirtuins regulate the biological functions

of various molecules post-translationally by removing

acetyl groups from protein substrates ranging from

histones to transcription factors and orchestrate cellular

stress response by maintenance of genome integrity and

protein stability. Finally, SODs belong to the first level of

antioxidant defence preventing lipid and protein oxidation

at the very early stages. All the vitagenes operate in

concert building a reliable system of stress detection

and adequate response and are key elements in stress

adaptation. Our studies clearly showed that supplying

vitagene-regulating nutrients (carnitine, betaine, vitamin

E, etc.) via drinking water could significantly improve

adaptive ability of poultry/farm animals to commercially-

relevant stresses and prevent decrease in their productive

and reproductive performance.

Biography

Peter F Surai has his expertise in Animal and Human Nutrition and published a

number of papers as well as two books (“Natural Antioxidants in Avian Nutrition

and Reproduction”, 2002; and “Selenium in Nutrition and Health”, 2006) which

became textbooks for animal nutritionists. His recent research is devoted to

the development of effective strategies to fight commercially relevant stresses

in livestock/animal production. He successfully transferred vitagene concept

from Medical Sciences to Animal and Poultry Science and developed stress-

prevention programs based on supplying vitagene-regulating nutrients to farm

animals via drinking water. He held Honorary Professorships in Nutritional

Biochemistry at various universities in the UK, Hungary, Bulgaria and Ukraine,

and became a Foreign Member of Russian Academy of Sciences. For the

last 15 years he has been lecturing all over the world visiting more than 70

countries.
