Further questions:
1)What 'results' is Susan seeing?
Rapid resolution of chronic muscle
myopathies pretty much sums it up. Increased stride length, more fluid
gait, better jumping performance, better recoveries after work.
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?
The organic form is considerably more
expensive, although I don’t have the price here in front of me. I
think the advantage is that the organic form has less risk of toxicity issues
if fed in fairly large amounts---although as I’ve said in numerous
lectures, you have to try pretty hard to get real toxic issues in orally
supplemented inorganic Se, but it is an issue to consider. I don’t
have a problem prescribing judicious supplementation of selenium yeast in some
horses without first ascertaining selenium status via lab assay. The
supplement itself isn’t cheap, but it’s a lot less than serial
assays at $80 a pop plus farm call.
3 ) Does 'organic Se ' differ from a chelated mineral?
Essentially the same concept.
Inorganic mineral bonded to an organic molecule, in this case, a yeast.
