Abstract
The invention provides a device adapted to apply a chemical to an animal requiring treatment with that chemical. In particular the device applies a parasiticide such as "Pouron" to the animal which is attracted to the device by feed or a lick in a container associated with the device, the device being activated by movement thereof resulting from contact with the animal or wind.
Claims9
A vertical applicator for a biologically active substance comprising:
- an anchor for anchoring the applicator at a desired location;
- a substance dispensing system, resiliently and pivotally supported by the anchor, comprising a reservoir for containing a biologically active substance, a dispensing element for dispensing the substance to an outlet, means for interconnecting and for conveying the substance from the reservoir to an inlet of the dispensing element, a catchment zone, located adjacent and below the outlet of the dispensing element, for receiving surplus substance dispensed by the dispensing element, and means interconnecting the catchment zone with the reservoir for recycling the surplus substance from the catchment zone to the reservoir;
- and
- a lure holder for holding a lure to attract an animal into contact with the dispensing element.
