Abstract: The present invention provides an improved head restraint that can be used in conjunction with conventional cattle chutes that are equipped with head gates. It provides the advantages of being humane by causing little or no discomfort to the cattle being restrained. Its implementation can reduce the human labor requirements associated with treating a herd of cattle and generally leads to savings in medication by virtue of being able to more accurately apply medications to the eyes of a cow having a stabilized head as compared to loss of medication when dealing with a struggling animal that is jerking its head around during the procedure. Its use greatly reduces the risk of injury to the animal and the person administering the treatment to the animal. Head restraints of this invention offer the advantage of being capable of being affixed to existing chutes of differing sizes.

Abstract: An aerial pen raised and lowered by a driven land vehicle has sidewalls defining an open bottom, a retractable platform for a targeted animal to stand on, a livestock head gate, and a retractable crowding gate cooperatively arranged with the deployed platform and head gate for securing the targeted animal for aerial carrying. Use of the aerial pen is like practicing, on a large-scale, a box-trap style ‘pursuit-and-pounce’ of cattle catching, albeit at an unhurried pace of pursuit, followed by an unhurried pounce. The box-trap style capture might be likened to the activity of ‘pouncing’ or, more fancifully, likened to the activity of netting as practiced by insect collectors with aerial nets (eg., butterfly nets). Presumptively, the livestock animal is sick or otherwise slowed, which permits this activity to be practiced without harm to the animal.

The upper neck restraint is adapted to swivel into a position forming an inverted U-shape over the top of the lower neck restraint, and the nose restraint is adapted to swivel by horizontal motion into a position forming a closed U-shape with the lower neck restraint.

Abstract: A livestock chute for confining and controlling an animal including a pair of spaced apart side frames connected by support members to provide an elongated space into which the animal may be driven, a tailgate near the rear end of said space and a head gate assembly supported near a front end of the space which includes an expandable and contractible opening which, when expanded, allows the head of the animal to extend therethrough and, when contracted, surrounds the neck of the animal to prevent removal of said animal's head therefrom. A gate carriage is mounted near the top of the side frame for longitudinal movement relative thereto and from which the head gate assembly is suspended for movement between a terminal position near the front of the space and selected positions nearer the rear of said space. Preferred embodiments include a squeeze assembly for engagement with the hip area of the animal.

Abstract: Apparatus for restraining the neck and/or head of a farm animal having a frame with a base, a top and opposed sides parts, which are spaced apart to allow at least the head of said animal to pass between these parts. Flexible belts extend between upper and lower locations connected to the frame and which are spaced respectively above and below the neck and head position of an animal to be treated, the belts having side portions connected to the frame sides by extensible means tending to hold these side portions apart. A fluid cylinder is attached to top ends of the belts so that when an animal has placed its head between the belt side portions these can be pulled inwardly against the side of an animal's neck or head to restrain movement of the animal.
