I have a 6 year old gelding, I've had him for 3 years. When I first got him he had some episodes after eating which weren't quite a colic, weren't quite a choke, were just what I could best describe as a good old fashioned stomach ache. He would lay down about 10 mins to half hour after eating, not in terrible distress, but clearly uncomfortable. I could get him up and walk him, he would usually poop once or more and get himself straightened out in an hour or two. I had the vet out but of course he was usually straightened out and munching hay again by the time he got here. Well, I changed his grain from pellets to textured and reduced his feed and he never had it again for the last 1.5 years.
Well I just got some hay that smelled and looked great but seemed sort of clumpy like it had not been turned properly and I thought to myself he was eating too much too fast and sure enough he had one of these episodes where he laid down and groaned a bit, now he's ok.
Is this a colic or maybe a choke and what is the proper treatment if it happens again? Has this happened to anyone else's horse at feeding time?
