The usual management of a horse with RDC is small frequent pelleted food split into 4-6 small feeds a day and grazing limited to 15 minute periods a few times a day and reduction or elimination of hay from the diet..
If he is still having problems then maybe you should chat to your vet about his managment and talk about getting him back on meds.
There are also a number of additives you can use to aid the gut.Probiotics and digestive aids may just help to keep your pony healthier longer.
