For how much Vit A she's getting, (I just looked it up so these are the numbers from the manufacturers) from the vitamin supplement (Farnam's Vita-Plus) she gets 50,000 IU/serving and the Enrich 32 gives her 24,000 IU/serving. So she's getting about 74,000 IU per day from her hard feed.
The grass is also really starting to grow here and that probably makes up 1/3 her total daily intake of food.
I just looked that Mare Plus up on Smart Pak. It looks really good. However, the packaging advises against feeding it in addition to any other feed that has added selenium... The Mare Plus and the Vita Plus both have 20 mcg, per serving, of selenium... The Enrich 32 I'm feeding has 1.5ppm of selenium. Could that cause an overdose?
We do live in the PNW which is typically very low in natural selenium but I've never had anything tested so I don't know for sure that Lacey is deficient in these things or that her pasture is...
Also, on SmartPak, Mare Plus only has the whole declared ingredients thing per pound, no per ounce/serving...
If I do the math correctly, the Mare Plus appears to give 100,000 IU of vit A per serving while the Vita Plus is just 50,000 IU per serving.
Is 124,000 IU vit A per day going to cause Lacey to go all vitamin A overdose on me?
If you all think she'd be fine with that, I'm happy to get her the Mare Plus. I just don't want more issues. Haha
Here are the lunks to everything so you don't have to go searching:
Enrich 32: Purina Horse Feeds - NATURE'S ESSENTIALS
Mare Plus (note that the declared ingredients are only per lb): Mare Plus - Horse Multi-Vitamin Supplements from SmartPak Equine
Vita Plus: Vita Plus - Horse Multi-Vitamin Supplements from SmartPak Equine
Thanks HAMP (hahaha)! :) I will look into that. I'm not sure how dry I'd be able to get her legs, I towel dry them very thoroughly after washing but her legs are generally still a little damp after that and, since we're in the NW in the spring, it's going to be very difficult to get her legs bone dry.
But if a little dampness is acceptable, it sounds good to me!
DraftX, do you know how much copper is recommended per day? It looks like she's getting 185 ppm from her Enrich 32 (but I'm not sure if that's per bag or per serving) and 4 mg/serving from the vitamin supplement she's on (Vita-Plus).
I just did a Google search and it appears like copper is one of those super tricky things to supplement... That makes me nervous a little.
Thank you all for your help so far. I appreciate it. :)
