Get The Most Out of Your Organic Selenium Supplementation With Selisseo®
WHY SELISSEO® ?
Selisseo contains 100% hydroxy-selenomethionine, a pure and highly available form of organic selenium.
Selenium is an essential trace mineral for animal nutrition. It plays a key role in antioxidant defense, immunity, reproduction, and inflammatory modulation processes. While inorganic Se sources, such as sodium selenite (SS), are commonly used as feed supplements, recent research confirmed that organic Se, specifically selenomethionine (SeMet) or hydroxy-selenomethionine (OH-SeMet), is much more easily integrated into the body.
Selisseo® is FDA-approved for use in poultry, swine, and cattle in the US and approved for use in all species in Canada.
CONSISTENTLY PROVIDES
100% PURE OH-SeMet
On average, Selenium Yeast (SY) products contain 60% SeMet and the amount of SeMet varies from batch to batch, while Selisseo® consistently provides 100% selenium as OH-SeMet, batch after batch.
Selisseo’s consistent particle size without fines makes for safe and easy mixing in the feed with low dust levels.
HER BENEFITS
Selisseo® helps maintain higher milk yield and milk quality under challenging conditions (such as parturition and heat stress) while enhancing the cow’s antioxidant functions.
HER BENEFITS
- Improved dairy cow Se status: Increased Se storage in both the plasma (+125% vs SS (1), +7% vs SY (2)) and milk (+22.8% vs SS(1) + 18% vs SY (2))
- Better antioxidant status: higher activity of glutathione peroxidase (+46%) and Total antioxidant capacity (+19.6% vs SS)(1)
- Lower somatic cell count:
- 0.1 ppm Selisseo delivered similar results to Selenium Yeast 0.3 ppm
- 0.3 ppm Selisseo (recommended usage) provided a 64% SCC reduction compared to Selenium Yeast (2)
- Lower drop in milk yield: When under heat stress: +9.3% vs SS (3)
- Positive modulation of several oxidative stress biomarkers under heat stress conditions:
- Improved total antioxidant capacity (+20% vs SS) (3)
- Lower plasma H2 O2 (-18.5% vs SS) (3)
- Lower plasma nitric oxide (-22.9% vs SS) (3)
BENEFITS FOR CALVES
BENEFITS FOR CALVES
Selisseo® allows selenium to be transferred from the dam to the calf, promoting calf health.
- Higher Se content in heifers plasma:
- +13% at 2 weeks pre-calving & +16% at calving vs SS (4)
- Higher Se content in colostrum:
- +20% vs SS (4)
- Increased Se status of newborn calves:
- +14% vs SS (4)

Determination.
Seleno-Yeasts (SY) used as feed additives are known to contain different Selenium (Se) species. Seleno-Yeasts has been shown, on previous analytical methods, to contain selenomethionine (SeMet), selenocysteine (SeCys), selenate (SeIV), and selenite (SeVI), and various other organic and inorganic Se forms identified but rarely quantified…
