Selenium Deficiency is a Widespread Problem
Leading selenium specialists meeting in Prague this
week have concluded that humans and animals alike across Europe typically fall
short of the optimal dietary intake of the nutrient selenium.
Speaking at Alltech's annual European Selenium Conference: â€œSelenium in
animal and human health - Nutrition inspired by natureâ€, the experts emphasised
the detrimental effect that this deficiency can have on health.â€œWe hear that
selenium is important - that is not enough - it is essentialâ€ said Professor
Gerhard Schrauzer of the University of California, San Diego,
While speakers concurred that
selenium supplementation could provide a potential solution, inorganic selenium
salts are not the solution due to their low 'bioavailabilty' and sustainability
in the body.
Research comparing organic selenium supplementation, in the
form of Sel-PlexÂ®, (Alltech's organic selenium produced by Saccharomyces
cerevisiae CNCM I-3060) to selenite supplementation in the diets of ruminants,
pigs and poultry was presented.
â€œCompared to selenite, Sel-Plex resulted
in an extra 4.5 chicks per hen. In breeders, Sel-Plex resulted in more uniform
chick weights and length. Over 36 trials in breeders, replacing selenite with
Sel-Plex gave an average of 35 g/bird more and FCR (Feed Conversion Rate) was
reduced by 6 pointsâ€ said Dr. Peter Spring, Swiss College of Agriculture,
Irish consultant, Dr. Wallace
Henry, found similar results in pig diets, â€œChanging from selenite to Sel-Plex
in sow diets gives between 0.57 - 0.72 extra weaned pigs per annum - that's 645
pigs per 1000 sows. Pigs from sows fed Sel-Plex are also heavier at weaning by
â€œCows fed Sel-Plex tend to produce a much greater amount of
seleno-protein P. In beef, Sel-Plex increases the GSH-Px in the tissue that
enhances oxidative stabilityâ€, according to Dr. Darren Juniper, Reading
