My 14 year old Tennessee Walking Horse gelding has had chronic diarrhea since I have owned him. Despite my best efforts, he continues to have diarrhea.
He gets routine fecal egg count tests, which always come back low and is on a Veterinarian recommended deworming schedule. I have tried probiotic and yeast supplements. I have also tried a daily high fiber (psyllium) supplement, as directed by my Veterinarian. Additionally, I have tried a couple different types of grain and hay to see if that would make any changes. My most recent effort at getting control of the diarrhea problem was placing him on a 10 day course of Metronidazole (Flagyl). Unfortunately, none of these treatments have been of any help.
His current diet consists of a ration balancer and bermuda grass pasture. He maintains an excellent body condition and acts as if he feels great.
Should I just let the diarrhea problem go and accept that he's just going to have chronic diarrhea or continue to pursue treatments for it? Do any of you have horses with a similar issue? If so, what have you done for them to treat the diarrhea?
Thanks for any input you have!
