Abstract: A hoof block is provided that joins with a livestock hoof via an adhesive. The block can include a body bounded by an interior edge and a curvilinear exterior edge approximating an outer edge of the hoof and multiple shearing polygonal apertures extending through the body. Each of the shearing apertures can have a pointed end and can lay along a reference line that can be disposed at an angle, for example, 30-60 degrees inclusive relative to the interior edge. The apertures can be joined with bridges that shear through the body when the hoof block becomes removed from the hoof and encounters a pump impeller in a livestock facility. The block can break into pieces that do not substantially impair continued operation of the pump impeller, and yet can support the standing and walking loads of the livestock while on the hoof. A related method of use is provided.

Abstract: A lure 1A of the present invention has a body 2 and a lip part 3 projecting from the body 2, and the lip part 3 is provided with a hologram sheet 4. As the hologram sheet 4 of the lure 1A reflects light while the lure 1A dives and swims in water, a target fish is easily attracted by the lure 1A.
