selenium deficiency

At the reccomendation of an equine professional or a vet and blood work? Those are majorly different.

He was muscle tested - applied kinesiology. My farrier/certified lameness specialist/holistic health/dynamite distributor was the one to suggest the selenium as he had the same issues with one of his TBs who also lost weight/muscle/etc when moved onto the local pastures here in OR where the selenium is almost non-existent in the soil.

My friend has had 2 TB mares, both with Selenium deficiency. They were next to impossible to keep weight on them, she tried everything! She ended up getting blood tests done, and they were both Selenium deficient... so weird!

what specifically (if you know) has she done maintenance wise after that diagnosis?

Here in Ok we're pretty deficient for selenium in the soil. Actually, it's pretty non-existent. I have noticed problems with tying up in some horses and in new borns, I've seen more instances of them being really 'down at heel'. I've started supplementing the mares in the last trimester of the pregnancy with a very small dose of ESe and I've not had a down at heel youngster since I started it. Anyone who ties up also gets supplemented very minimally, and I've not had problems since.

Crimsonsky - Her vet had to come out every 3-4 weeks to give selenium shots to the horses, you can also buy selenium shots from the vet if you don't want to pay for their trip to come out if you are confident enough to give them yourself.

Interesting. I wonder why a shot instead of a feed through supplement.

Sorry -- Talked to her about this, the first few weeks the vet had to give them shots, then prescribed Selenium in a powdered form to add to their grain daily.

Oooohhhh that makes sense. I give Dynamite's Premium E-Selenium which has proven quite effective.

Are you feeding anything else that has selenium added in addition to the one from Dynamite? Their supplement looks like it's not actually supplying all that much- 0.342 mg per 2 scoops (recommended dosage). That's only about a third of the minimum RDI for a horse getting 20 lbs of feed per day based on the NRC's recommendation of 0.1 ppm.

The maximum recommended dosage is 2.0 ppm (or about 18 mg for the same horse), so there ought to be enough headroom to supplement the full minimum 1 mg especially in a low selenium area like ours
