A method and instrument for placing an implant in the teat duct and udder of an animal, as a milk cow. The instrument has an elongated tubular member having a passage accommodating the implant. The tubular member is adapted to be inserted into the milk duct through the discharge end thereof. A head having finger gripping ears is attached to the tubular member. The implant is moved from the passage with a piston connected to a rod extended through the head. A hand engaging member secured to the rod is used in cooperation with the ears to apply force to the rod to move the piston in the passage to move the implant into the teat duct and udder. The implant has a core of an elongated flexible plastic string. A plurality of bands are clamped about the core. Alternate bands are coated with a first metal, as silver. The remaining bands are coated with a second metal, as gold. All of the bands may be coated with the same metal, such as silver. The implant includes a capsule implant containing material that reacts with the silver to produce silver ions which have advantageous antibacterial effects.

Animal ear tag shield

A clipboard and shield apparatus having a board with a top flat surface to accommodate writing paper and a bottom with ribs forming pockets which serve as barriers to prevent a sharp object from moving off the apparatus. The board has high impact strength provided by laminated sheet members bonded together and surrounding a high strength core comprising a woven mat of high density polyethylene. A hand grip is attached to one side of the board. A fluid dispenser or flashlight is carried by the hand grip.

Clipboard and shield

An insecticide dispenser attachable to the ear of an animal has a ball shaped body accommodating insecticide. The body has a slit providing a mouth that can be opened allowing access to the inside of the body. A connector having a pin secures the body to the ear. Annular resilient members surround the pin adjacent opposite sides of the ear minimize snagging of the dispenser on objects.

Implant for inhibiting mastitis in dairy cattle

Pedicure implement

A dilator for a teat of a dairy cow operates to facilitate the flow of fluid from the teat. The dilator has a body having a passage adapted to be positioned in communication with a duct of the teat. An elongated tubular member extends from the body into the duct. The tubular member has a passage allowing the flow of fluid through the dilator. A one-way valve mounted on the body allows the flow of fluid out of the dilator and restricts the entrance of external foreign substances back into the passage and duct of the teat. The valve has flexible side walls terminating in normally closed lips. A slit mouth is located between the lips. The slit mouth can be opened to facilitate the dispensing of medicinal compounds into the teat and udder of the mammal. An inserter having a rod extended through the one-way valve and tubular member is used to place the dilator in the teat duct and duct outlet, with the one-way valve located at the terminal end of the teat.
