The health of farm animals depends on many factors and they all indicate that
food plays an important role in preserving health, improving reproductive and
productive characteristics and functioning of immune system. Besides numerous
nutritional factors, antioxidants play a special role in the struggle for
survival and good health state. An oxidative stress represents a condition
induced by generating and reacting of reactive-oxygen species (ROS), and
their toxic products, on different metabolic and physiological processes. The
generating of ROS is induced by both endogenous and exogenous factors. In the
case of the organism inability to expel the causative agents of oxidative
stress they can damage cell lipids, proteins or DNA thus endangering the cell
functions. Lipid peroxidation is a process which can lead to degradation of
lipids and damage of cell membrane. Selenoenzyme glutathione peroxidase can
protect organism from peroxidative damages, decrease the level of
malondialdehyde protecting in this way a muscular tissue from oxidation.
Recent research has shown that selenium has an effect of preserving sensory
characteristics of meat and its texture, what is of great importance for
consumers. Animal tissue incorporates supplemented selenium quickly thus it
is possible to produce a selenium enriched meat and eggs. Selenium also shows
positive effects on meat quality: it reduces water loss, influence the
stability of colour, prolongs oxidative protection, and therefore the time of
its shelf life.
