Using dispensers on organic farms

PETA Dispensers can be used very effectively on organic farms.

Bloat

There is some evidence (although not huge evidence) that supplementation to animals of salt has a depressive effect on the foaming action of bloat.

Minerals

There are organically derived mixtures (aloe vera, cider vinegar) tinctures of various sorts which can be CARRIED through the dispenser using salt.
