Thank you everyone for your input!
In regards to the oats, it’s part of the standard barn protocol. I’ve asked to have it taken out in the past, but it seems they always creep back in. It sounds like I need to revisit that conversation.
He was on Body Builder which is a rice bran oil supplement, but didn’t care of the liquid either by syringe or top-dressed on his feed. The Cool Calories, Cocosoya, and rice bran pellets are all going to be on my list to compare and talk to the vet about.
He had a massage appointment over the weekend and the therapist seemed to think a lot of his twisting is from super tight PSOAS and hamstrings. I’m going to keep working with her and doing the stretching exercises she’s advised. I’ve already seen a difference after two appointments.
I have an appointment with the farrier setup to talk about the frog pads and hear his recommendations on moving foward as well. I am currently feeding a biotin supplement. Started that in January. There is improvement, particularly in his front feet. The hoof wall is much stronger and holds the shoes longer. I think the issue is two-fold in the hind end because of the weaker hoof wall and the twisting movement as he walks.
I have nowhere to store any alfalfa as the barn feeds its own grass hay mix. He is on soaked alfalfa pellets, which I can increase at any time.
Thanks again, everyone!
