I do not know either.
I'll have to see about getting our hay tested this spring/summer. I'll have to research where and how to do that.
IS there a place to figure out the deficiencies in our areas?
If you have a Co-op, call them and ask them two things:
1. The name and number of your county Agricultural person.
2. Who would you take or send soil samples to for testing.
Call the Ag person first as it is their job to know the answer to #2 and you may not have to send a soil sample for testing.
In the meantime, I would keep the protein percent as low as possible for the Minis.
NOT because of the protein itself but because the protein source is always soy in these feeds and ration balancers.
Much as I love Triple Crown, that "30%" means it took a lot of soy to get 30% protein.
Does "know of" mean you can get any of these? You're sure lucky if you have that much of a choice readily available
I looked up the G/A on all of these; I have to wonder why these feed purveyors think everything under the sun that's an RB needs to be so high in protein
If you can easily get your hands on any of these, I guess my pick would be the Buckeye Gro 'n Win.
Here are the ones I know of:
Purina's Enrich 32 = 32%
Buckeye Gro 'n Win = 12% protein but the NSC is high (16%)
Seminole Equalizer = 32% protein
ADM Alliance Gro Strong Mintrate = 33% protein
Triple Crown 30% = 30% protein
ProAdvantage Grass Formula = 30% protein
A ration balancer that is soy/oat/corn free to check on availability would be the McCauley's M-10 Balancer. It's what I feed to my food intolerant horse and one of my metabolic horses. There is a dealer locator on this site. McCauley's® M10 Balancer
It is 10% protein and boy does it keep my soy-intolerant horse the sweet/loving Fella I always knew he could be
The next thing I would do, would be to call whatever company you choose (they generally have an 800 number on the bag or check their website), explain you have Minis, and ask what is the rock bottom measured amount
the Minis would need to meet their daily vit/min requirements. Then use a measuring cup and stick to that.
The business of feeding "by the scoop or just a coffee can" has long since gone out the window when the health of the horse is hanging in the balance
I apologize if I come across gruff - I don't mean to - just strict. I have become very "feed jaded" since two of my four horses have developed metabolic issues
