Thanks for the tips!
Can you give us some ideas of what brands are available in your country "Belgium"....
Many of our members do not realize that when in a foreign nation feed-stuffs might and do vary greatly.
Assisting us with some brands would allow our knowledgeable members to do some research and offer ideas that are available to you to purchase in your country.
So, there's a lot of brands here of course. I'll explain a few - Pavo, Marstall, Cavalor, Mijten, Lannoo, Equifyt, Hartog, Aveve.
Pavo creates muesli's mostly, mixes that generally look like a bit of lucerne, wheat, some pellets,... It's a general thing. Same goes for all brands, actually. Equifyt is the natural brand we have here, no grains, most of the time based on herbs. Lana doesn't eat it at all - She'll look at you, pick up her bucket, and throw it at your feet, contents included. Mijten is our local brand, generall smells a bit odd, sticks together often like it's pumped full of sugar. Marstall I think most people know - it's from Germany. She's been on the Faser light (no grains, melasses,..) but moving to Lannoo fibermix (for horses with ulcers, has lucerne, grain, etc. for some reason, but she's done well on it before). Then you've got Cavalor, also a muesli brand. The starch is apparently through the roof, because not only does she not stop breathing hard with this brand - she also gets a skin reaction in bumps. Hartog has some feeds that are generally more grass-based, like these; https://www.hartog-lucerne.com/krach...ig/luzernebrok https://www.hartog-lucerne.com/krach...verig/grasbrok
This one I find rather interesting, but I'm not sure if Lana will actually deign to eat this, because she's picky - https://www.hartog-lucerne.com/ruwvo...arden/gras-mix
There should be the regular number on the end of the page, and google translate to translate the pages does quite a good job!
I've never tried Hartog before though, so I have no idea how that would turn out.
As for the wheezing, she really doesn't? I know it's perhaps hard to believe (seven vets and a clinic agrees, but then they're stumped as to why she doesn't wheeze or have damage to her lungs) but it's the truth. She also doesn't breathe as fast as normal horses with heaves do, like they're having a little attack on their breathing and they're working themselves into a hyperventilation bout. Lana breathes slowly, measuredly. The only way you can tell that she has trouble is her stomach slowly going up, tightening, and doooown. It's super slow, and that's why most vets can't hear much either. She's controlling her breathing big time. She also doesn't squeak, or wheeze, or have flared nostrils, or acts like she's going to faint. She just looks a bit sad, a bit mad, and has sunken flanks from the lack of air. I'll try to video it and upload it in a few hours.
She's now out with a rug, as I want to limit her time indoors. She doesn't truly care, so long as she gets food.
