We just got a new batch of orchard grass hay and it smells so sweet and yummy. The horses love it, of course, but Paddy's tummy doesn't. Since we made the switch (and yes, I switched gradually from the last batch), he's had the runs. I've tried probiotics, which only helped a little bit, so my next step is to try a different hay.
All the hay here now is:
--orchard grass (which I've got)
--alfalfa or grass/alfalfa (Paddy cannot have alfalfa per vet's orders)
--mixed grain hay (wheat/oat/barley)
I bought one bale of the mixed grain hay to see if that helps. It is quite stemmier and more fibrous than the grass hay so I'm hoping/wondering if that will help with is diarrhea problems.
Years ago I boarded at a barn that fed oat hay and I don't remember there being any problems with it, but that was before I tried to educate myself on equine nutrition.
I understand that this hay is likelier to be higher in NSC, but Paddy doesn't have any IR problems so hopefully it won't be an issue.
I will be giving him a small amount in his ration to see if that helps, but I wanted to see if anyone could share their experiences.
I tried doing a search, but came up with nothing - the search function appears to be not working, as when I searched for "oat" there were 0 matches - unlikely!
