Selenium is an essential trace element with known effects in reducing oxidative stress and improving animal performance. Since selenium is involved in enzymes related to the reduction of oxidative stress, negative effects of stress factors (such as heat or stocking density) will be reduced. Besides, selenium also allows for better immune functioning.

These factors will all contribute to the fact that more energy remains available for production, allowing for an improved performance when the animal has an optimal selenium status. As explained in the previous campaign topics, L-selenomethionine is the most effective form of selenium since this is the only form of selenium that can be stored in animal proteins.

Therefore, L-selenomethionine allows for an optimal selenium status in the animal and can more beneficially support performance compared to other selenium sources. This valuable effect on performance has been shown in aquaculture, poultry, pigs and ruminants.
