ABSTRACT:
In a flow apparatus for adding liquid additive to drinking water for cattle, a drinking trough (13) is supplied with treated water from a header tank (18) topped up from a mains supply (15) in response to changes in level in the trough (13). A siphon (19) delivers water from the header tank (18) to the trough (13) down a primary tube (20) which is joined by a secondary tube (25) leading from an additive tray (22). Additive is sucked into the primary tube (20) without any substantial venturi effect, and is sucked at least predominately by the effect of displacement of liquid in the primary tube (20) below the junction (27), to ensure accurate dosage of additive. Preferably the primary tube (20) runs full substantially immediately after flow commences in the primary tube (20).
