If you are converting your farm from sheep to dairy, here is our advice regarding treating your animals for bloat, eczema and mineral deficiencies, through water trough treatment.
Many farms will have sheep troughs (which are lower than cattle troughs). These will not allow the dispenser to float upright in the trough and have the dispensing head/nozzle above the possible “gunge” in the bottom of the trough.
Rather than replace troughs (immediately) you can use the #8 wire ability Kiwi farmers are known for to make a supporting frame that would be able to hang on the side of the trough to provide a rigid support for the dispenser. The outflow nozzle should be 50 mm above the bottom of the trough and held firmly in an upright position. This allows the dispensing action to happen unimpeded by angular distortion. The container is a sealed unit and it’s important that the inflow and outflow nozzles are beneath water level in the trough. Meanwhile the liquid material held in the dispenser container can be above the water level in the trough.
This can be done with literal #8 wire on the side of the trough or if skilled at welding, a support frame could be created for this purpose.
If you want to keep the dispenser out of animals’ reach, then you could create a freestanding frame to hold the dispenser and place it in the centre of large, round, low troughs. Just ensure it can’t get knocked over.
