I know that the first pelleted feed I ever tried, which I am not going to put down here because I know a lot of people feed tons of it and have no complaints, but my horses did not seem like they liked the taste of it and they all of a sudden started to lose large amounts of weight on it. I have come across the same problem with some others I have tried, they just would not eat it no matter what we did, they are grain addicts I think. We switched them over to the pellets from the grain and once they were completely switch over in a 2 week period, they would not eat. It did not matter if we let them sit there with it being the only source of food other than hay and grass, they just wouldn't eat it. The only one that some of my horses will eat is strategy and I really only have started recently feeding it to my stallion because the vet has diagnosed him with a minor ulcer and wants him on lots of hay and grass, pelleted feed (strategy), and alfalfa pellets. Other than that I have never had a problem with feeding good quality horse feeds made with grain. As I had said before the only reason I know that strategy works is because I have used it on rescues and some hard keepers.
Also on the subject of cribbing, I own a shetland pony mare that was a rescue. She has a strange habit but it is not cribbing. She will walk up to her water bucket, grab it with her teeth and looks like she is going to crib, but instead she arches her neck, picks the bucket up and lets it slam into the barn wall and watches the water fly, then runs and hides in the corner of the stall because she is scared of it!
You know how to make a miniature horse even smaller? Leave them in the dryer a little longer!
