QUESTION:

There is much discussion about the selenium-poor soils in Sweden. How does this affect horses and what can I do about it?

ANSWER:

It is true that many parts of Sweden have selenium-deficient soils, which is why it is important to conduct a mineral analysis of the roughage. Selenium is an essential nutrient for horses, and because it is toxic in excessive amounts, it is crucial to control the quantity added.

Selenium is included in most mineral feeds. However, it may be difficult to meet the requirement solely by giving a mineral feed, as this can lead to an excess of other minerals. In such cases, one can use Selo-E, a more concentrated product given in smaller amounts. Selo-E also contains vitamin E, as these substances work synergistically.
