Further questions:

    1) What 'results' is Susan seeing?

    2) In my geographic area it is safe to assume that animals are getting zero Se (as well as zero Cu and I) from locally grown feeds & forage. Granting that what is the functional advantage of feeding the organic Se vs. more of the inorganic, which would be more cost effective?

    3 ) Does 'organic Se ' differ from a chelated mineral?

 

(I hope everyone realizes that 'organic Se' means the mineral is in an organic compound, i.e. one with carbon, rather than having anything to do with 'organic  food' or 'organic gardening'.)

Just catching up, so beg pardon if the question has already been answered elsewhere.  Yes, selenium yeast is more bioavailable and has lesser potential for toxicity than does the inorganic form of sodium selenite.  Until recently, selenium yeast was not approved by FDA/USDA for use in equine feeds, so only sodium selenite was used.  Approval came through about a month or so ago, so its use will probably become more prevalent in the premium quality feeds.

 

As far as I know, the only place yet to purchase selenium yeast as a sole supplement (not integrated with other feeds) is from Platinum Performance www.platinumperformance.com .  Good product, but not cheap.  Probably still worth it IMO.  Diamond V Mills, the people that make Fastrack, also manufacture it, but aren?t really set up to sell it retail in small amounts---I think the smallest amount they really have available is a 600 mg/kg 100 lb bag.  I?m trying to get some more information from them, but they?re a bit overwhelmed by the sudden interest from horsey people.

 

So far, I?ve only used the selenium yeast supplement in a few Se-deficient horses in the practice, but were very pleased with the results.

I sent this out to ridecamp once but didn't see it posted so I'm trying again.

 

Does anyone know of an equine selenium supplement that is based on organic selenium derived from yeast rather than the commonly used selenium selenite?

 

Triple Crown feeds are now using the organic Se in their feeds and I have read that this is a much more readily absorbed or utilized form of selenium. Any opinions either way?
