My 8 year old OTTB suddenly stopped eating his grain yesterday. BO called me yesterday and said that he didn’t touch his morning grain but finished his hay and was drinking normally as well. Called again yesterday afternoon and said the same thing (dumped old grain out and scooped new for him; still wasn’t interested). Went to see him last night, normal temperature, active gut sounds on both sides, eating hay, drinking, and pooping normally. Soaked some of his grain in warm water to make a semi-wet mash, fed some of it to him by hand which he reluctantly ate. Soaked the rest of his ration and put the bucket in his stall with him, wasn’t interested anymore…
Went back to see him this morning during breakfast, dumped new grain into his bucket - he took a couple of bites and then went back to his hay. Took vitals again, all the same as last night. Turned him out with some hay, happily ate, drank, and relaxed, pooped normally as well. Lunged him lightly, everything normal there too.
The only change to his feed is that I ran out of his Smartpaks last Thursday (delayed the shipment a little too long) and the new shipment will be here on Wednesday. However, he only gets his Smartpak (joint, hoof, and Cocosoya) in the mornings, so he has been eating plain grain in the afternoons before this started happening.
His teeth are floated every 9-10 months (moderate cribber), but they don’t seem like they are bothering him currently. He had his knees injected a week ago and I have read that the steroids they use for injections can upset their stomach. However, if that was the case here, I figured this would’ve happened closer to when he got the injections done and not a week later.
He has never been scoped for ulcers and hasn’t shown any common signs of having them, but I am thinking that he may be developing them because of how he just stopped eating grain but is acting normally otherwise (his breed and cribbing habit definitely make him a good candidate for ulcers…). My vet said to keep an eye on him and that if it continues, he will come out to do some bloodwork and check his teeth.
Has anyone dealt with this? If so, what was the underlying cause? Thanks in advance!
