Does anyone else use cider vinegar, in their sheep's drinking water, as a homeopathic 'tonic'? A friend recommended it to me as being good for their health generally and also as being a useful adjunct for worming (I still use a proprietary wormer at the recommended intervals). I add 100 ml of cider vinegar per day to their water trough (the capacity of which is probably about 50 litres), when I refresh it, and rather than the sheep drinking less (on the basis that it might make the water taste 'sour') they seem to be drinking more (so I'm assuming that they find it not unpleasant). The cider I use is unpasteurised, it being one of the barrels of my home produced cider, with a 'mother' added to it, that reluctantly I ceded to the sheep at my wife's request. Does anyone else do likewise? If so, have they noticed any results from or have experiences to relate of its use?
