Recent research work does not question the well known need for Se, rather the form in which should be fed. Results of recent experiments illustrate the value of providing dietary Se in an organic form. Selenium has been shown to be important in reducing problems associated with tying up, poor performance and nervousness. There is also a link in its ability to limit free radical damage. Many factors lead to deficiencies of this nutrient. The most common cause is geographical areas consisting of soils, which are deficient in selenium. Horses that are exposed to heavy conditioning, fast growth and pollution can benefit from the supplementation of organic selenium.
Numerous University research studies have clearly and effectively demonstrated increased retention of Se, when fed in the form of Se yeast. Researchers have said that the fundamental error had originally been made with the choice of sodium selenite. Sodium selenite is not only a carcinogen, but acts as an oxidant.
Numerous University research studies have clearly and effectively demonstrated the benefits in supplementing chromium in animal diets. Some of the benefits are listed below in order to objectively evaluate the need for adding chromium to existing high quality diets.
Selenium is required in thyroid metabolism while converting active thyroid hormone (14) into the inactive thyroid hormone (13).
lnactivates heavy metals, especially mercury, lead and cadmium.
Selenium Yeast is reported to protect against radiation damage, even it given after exposure.
Evaluations of toxicity of different forms of selenium have shown that high Selenium Yeast is less toxic than inorganic forms of selenium such as sodium selenate and selenite.
A study with rats showed that high doses (1.5 and 3.0 mg/kg body weight) of organic selenium in Selenium Yeast did not have any toxic effects after 14 days. This level of selenium is much higher than the theoretical toxic level for inorganic selenium (Leiras, internal report).
A comparison of the toxicity of a selenite and a Selenium Yeast diet in rats showed that Selenium Yeast was much less toxic (Spallholz and Raftery 1987). No hepatotoxicity, cardiotoxicity or splenomegaly to 16 ppm dietary Se was observed in rats fed high Selenium Yeast over an 8 week period. Animals fed selenite at the same level showed signs of various toxicities.
