A novel bait station system attracts animals and applies an acaricide, pesticide, and/or insecticide onto the animal when the animal attempts to feed on an attractant, or when the animal feeds on the attractant. The bait station system contains an attractant bin, at least one horizontal applicator for applying the acaricide, pesticide, and/or insecticide to the animal, and at least one vertical pole-type support which positions the horizontal applicator in the proper position. Each vertical pole-type support is attached to a flexible joint which permits the vertical pole-type support and the attached horizontal applicator to displace when an animal pushes against either the vertical pole-type support and horizontal applicator and then returns the vertical pole-type support and the attached horizontal applicator back to the intended position after the animal stops displacing them. Each flexible joint is attached to the attractant bin or to elevating anchors which are attached to the attractant bin.

At least one embodiment of the invention provides a system comprising an inhalation exposure chamber and an aerosol delivery line connected to the inhalation exposure chamber. The aerosol delivery line is configured to produce a bi-directional and symmetrical presentation of aerosol to the inhalation exposure chamber. A laminar flow element is configured to create an ante-chamber where complete and turbulent mixing of the aerosol occurs. A radial exhaust and the laminar flow element enable laminar flow of the aerosol through the inhalation exposure chamber.

A method and an apparatus providing a combination mineral feeder and livestock sprayer with a mineral feed compartment having a door and a sprayer actuated by movement of livestock into the door. The door includes a roller applicator for imparting liquid treatment to the nose and face of an animal. The apparatus combines a reservoir of chemical into the unit and a pump to the sprayer. The apparatus is secured by a mat or surround attached to the base of the apparatus that accommodates the livestock thereon during use.

The invention relates to an automatically adjustable device for affixing to the nose of animals, which may be used simultaneously for administering medicinal or non-medicinal substances and/or for collecting and transmitting information about the animal by means of onboard sensors, the device being composed of a flexible support body and a pair of adjustable members that are connected by a system of swivel joints, allowing the articulation of the members in all directions. The system of swivel joints enables the adjustable members to automatically adjust to the wall of the nasal septum of each animal, which affords greater comfort and offers a larger area of contact between the face of the adjustable members of the device and the nasal mucous membrane of the animal.

A delivery device includes a collar device for wearing on an animal, a dosing probe disposed on the collar device for delivering a substance therefrom, an actuator configured to deliver the substance from the dosing probe through an opening formed in the dosing probe, a controller in communication with the actuator and configured to control delivery of the substance from the dosing probe, and a sensor in communication with the controller and configured to sense that the collar device is touching fur or skin of the animal and the dosing probe is directed towards fur or skin of the animal.
