I have an 18hh Belgian who is 26+ years old. I’ve had him 2 years. He began quidding recently and choked about 3 weeks ago on hay. He had his teeth done again right afterward and the vet noted his teeth were quite worn down and that it may be time to take him off hay. He choked again on hay last weekend, despite it being provided in a slow feed hay net, and continues to quid. I took him off hay right away and plan to keep him off it now.
My concern is how best to sustain him, especially through winter. His weight dropped dramatically 18 months ago from poor care at the last boarding facility. I spent a lot of time getting his weight to a good place. The new barn owner is a saint and she is just plain awesome. She has been soaking hay cubes for him and making sure they are properly broken up. He is turned out as much as possible, but I do bring him in when it’s wet and cold. I’m worried about a) weight, b) keeping enough forage in front of him and c) keeping him occupied when stalled, as it’s not his preferred thing.
Thoughts? Do I need to give him 20 lbs of cubes (dry weight? Wet weight?) to replace the 15-20 lbs of hay I was giving him? Any tips or tricks to sustaining this?
