This study had some really interesting charts even if you aren't into data, it just made it very visual on how feeding dry hay, soaked hay or haylage could have very different impacts, especially if you have a horse suffering with Insulin Dysregulation.
A snip for those not wanting to read all of it; 2 top charts are for an ID pony, bottom ones for a normal pony, showing GI response on the left charts and Insulin on the right ones.

Given the sample size its not really conclusive yet, but there is some interesting info there and visually descriptive of how a ID horse's reactions to the same stimulus are much greater.
