I was reading on a breeders site that they put apple cider vinegar in the goats water as part of their herd management. But I couldn't find any info on why they would. I searched on here and found some suggestions on using it as a cleaner and to spray goaties in the face when they're being naughty, but not much on putting it in drinking water, except one short sentence about it being a immune booster. Does it work? Do most goat owners do this? Can anyone shine light on this issue?
