My sister had to take her little mare to the vet yesterday as she was colicing. She had been a little off for a few days, but wasn't rolling and was eating fine. We thought she was just cycling and was a bit moody. Blood work showed she was dehydrated. If she had not recovered by this morning, he was going to put her on IV, but my sister said she seems fine today. Vet recommended top dressing her feed with salt to encourage her to drink more. I have been top dressing with salt for many years. I like to use mineral salt or himalyan salt. But I'm out of both so just been using table salt. About a half teaspoon. Might be a good idea to offer salt by hand this time of year; usually they will lick it up. Also have a salt block in the pasture. It made me add another water source in my corral today, just so they wouldn't have to walk so far to get a drink. I've never had good luck using electrolytes; just seems to cause diarrhea. Anyone have experience with electrolytes? My sister's little girl, Jackie O.
