Old horse loosing teeth
At his dental check up last week my 23yo tb lost his 4th tooth. He is now missing 2 at the front and 2 at the back, which explains why he has lost some weight recently. Before the appointment I had he eating all the nice green grass outside the paddock but when the vet flushed out his mouth, it all came out, it didn't look like he had swallowed much. Since, I have been putting the hose in his mouth everyday to check there isn't food building up in there and it seems ok but I am concerned that he's struggling to get enough roughage. He hasn't been able to eat hay for around a year.
He seems to do well with dry chaff (but I would prefer him to have it wet) and I was wondering if it may be best to stable him so he can spend the night eating as much chaff as he wants? At the moment he is turned out 24/7 in a group of horses and can only eat when I'm there (I feed him twice a day, about an hour each meal).
Preferably, I would soak chaff overnight for him, but would it spoil too quickly if I left a big bucket of watery chaff for him to pick at all night? How much chaff is he likely to eat overnight if he was stabled?
Anyway, does anyone have any advice for keeping him healthy and well fed in this stage of his life?
