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, USA. Potential solution
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, Switzerland. Pig diets
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 0.5 kg.â€
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 University, UK. Related Website
