SELCOTE ULTRA SELENIUM FERTILIZER
Fast and slow release for season-long selenium supplementation
FERTILIZING PASTURES WITH SELCOTE IS A SAFE AND EFFECTIVE WAY TO MEET LIVESTOCK REQUIREMENTS
Save on time, money, and labor of drenches and injections while maintaining herd health
Apply just once for year-round Se supplementation
A rate of just 1-2 lbs./acre provides the recommended level of 5-10 grams of Selenium per acre
Apply with spring fertilizer
No documented cases of toxicity from pasture applications of Se, according to Shelby Filley of Douglas County Extension.
Used widely in EU, Australia and New Zealand
Taken up by animals as an organic form, which is less toxic and longer lasting in livestock tissues
OSU Extension research supports the safety and efficacy of supplementing forages with Selenium
2013 trials showed weaned calves fed Se-fortified forages weighed up to 10% more than those on un-fortified hay, showed an improved vaccination response, and had higher slaughter weights and lower death rates
Selenium (Se) is an essential trace mineral for livestock.
Selenium deficiences hurt herd performance, causing reproduction and production losses including:
Poor weight gains
Weak immune function
Clinical deficiences cause white muscle disease
Selenium deficiency is caused by low Se intake in feed; forage generally reflects the Se in the soil where it is grown. Most of western Oregon is Se deficient, making supplementation crucial.
Like any essential nutrient, both deficiency and toxicity are concerns for livestock production.
Selenium toxicity is strongly influenced by the form of Se in the animal's body--generally organic or inorganic.
Inorganic Se is found in injections and feed supplements; it's effect on the animal is generally short-lived, but large does can be toxic.
When plants take up Se fertilizer, it is converted to an organic form, which is incorporated into livestock tissue; organic Se is less toxic and longer lasting.
" Fear of toxicity is the biggest obstacle to selenium application with fertilizer, yet toxicity is much less of a problem than the health and productivity losses associated with Se deficiency. Additionally, I haven’t seen or heard any reports of toxicity due to pasture application of Se. All toxicity problems are from injectable Se or from someone mixing selenite into their trace mineral mixes themselves."
