How The Dispensers Work
All PETA Dispensers are used in animal water troughs.
The treatment material, such as bloat control material, zinc or mineral supplements, is added into a container (a standard jerry can or flagon). Trough water is then added too and the dispenser is inserted. The lid (which is part of the dispenser) is screwed closed.
The dispenser is then placed head-down in the trough and dispenses the treatment material continuously over its designed time frame. Simply by drinking water from the drinking trough, your livestock receive their required dose of treatment.
It sounds simple enough, but there is actually a lot of robust science behind the precise design of each of the dispensers. This scientific and patented design is what makes it all possible.
