depending on the severness, if your horse has bloated, if the symptoms are too severe, call a vet. If the horse is laying down on its side, get the horse haltered & up on its feed. Lead it around, get it to pass something. If it wont, the horse may need an anemema (sp?). My mare bloated once last year, I had not timed her on how long she had been on the field & she over-ate & bloated. I had to walk her out quite a long while before she would urinate or take-a-dump. I usually only keep them on the field for about 30 hour a day, but sometimes I get carried away with other things
