Microelements such as selenium, zinc and copper are indispensable nutrients
for preserving major physiological functions, improving reproductive
characteristics and overall health state. By their adequate use different
ailments are prevented, while at the same time they have a positive effect on
fertility and resistance. Insufficient quantities of these microelements,
inadequate absorption and interaction with other microelements may lead to
the impairment of the immune response due to metabolic and oxidative stress.
In recent years, mainly organic forms of microelements have been administered
to animals because they show better biological availability and can be
retained longer in the organism. Besides, organic forms improve quality of
products for human nutrition. Antioxidants should be added in optimal
quantities in food for dairy cows with the aim of maximizing immune function
and protection of tissues.
