A castor assembly comprising a base plate, a wheel assembly extending from base plate, a vertical support member plate, a vertical retaining member, a retaining bolt, and a horizontal retaining member. The vertical support member has a pair of vertically spaced slots. The horizontal retaining member extends from the retaining bolt and is movable along the retaining bolt in a way that the horizontal retaining member is positionable between an open position, a first closed position wherein the horizontal retaining member is disposed in the first slot to retain an object having a first size in the object receiving space, and a second closed position wherein the horizontal retaining is disposed in the second slot to retain another object having a second size that is different from the first size in the object receiving space.

An animal handling system (AMS), for positioning an immobilized animal in a predefined configuration therein, comprising an automated tuning unit, including: a proximal portion, held outside a medical device including: at least one inner shaft and at least one outer shaft, the at least one inner is telescopically maneuverable within the at least one outer shaft providing a variable telescopic mechanism; and a distal portion including: a configurable encapsuable life support system (ELSS), the ELSS is rotatable about a longitudinal axis of the at least outer shaft and the at least inner shaft and translationally moveable parallel to the longitudinal axis by means of the maneuverable telescopic mechanism.

An animal restraining chute having a four sided cage with a closeable front and rear opening and two sides constructed from a series of ribs made from a single bent component to provide structural support. A partially closable front gate closes the front opening and restrains the head of the animal, and a curved rear pusher gate secures the hindquarters of an animal. A rotatable belly restraint pins the animal to one of the sides. The chute is rotatably mounted on a vehicle or platform to lay the animal on its side. The chute includes four hydraulic activated leg latches for securing the legs of the animal. There is a movably attached staging area located at the rear of the chute to allow for the positioning of animals waiting to enter the chute. Each of the movable components of the chute are hydraulically and remotely controlled.

A reader comprising: a panel; two antennae each associated with a respective race to transmit and/or receive information to/from an electronic animal tag in that respective race; and an electromagnetic shield to impede an antenna from transmitting and/or receiving information to/from an electronic animal tag not located in the respective race of that antenna; a system for reading electronic animal tags comprising: a plurality of readers each located at or near a wall of a respective plurality of races, wherein each reader is at least partially shielded by an electromagnetic shield; each reader being longitudinally offset with respect to at least one other reader in the plurality of readers; and methods of constructing and using a reader.

A chute for immobilizing an animal (e.g. cow) wherein the chute during a hoof-trimming operation or the like. The chute is comprised of an inner wall and an outer wall and a front and rear gate. The inner wall has a rectangular opening near the front thereof with a backing plate having a hole secured over the backside of the opening in the inner wall. A removable pad is comprised of a rectangular frame which fits in the opening in the inner wall. The frame has a flexible cover (e.g. anti-microbial material) secured over its front. An inflatable bladder (e.g. pneumatic inner tube) is inserted through the hole in the backing plate and is positioned within the frame and behind the cover. The bladder is then inflated whereby the bladder expands to produce a pillow-like support for the cow's shoulder while the cow is in the chute.

An animal harness for use together with a stand by veterinarians and groomers and the like in which elongated members form an adjustable size loop that encircles the animal's head and extends to cam buckles supported by the stand.

A portable enclosure for capturing and retaining an animal features a pen carried alongside an ATV, a front opening in the pen, and at least one door movable between open and closed positions at the front opening. A lock member is carried above the front opening, and is displaceable into and out of a locking position engaging the door. A rotatable actuation member resides overhead of the lock member and is operable by a foot pedal to draw the at least one lock member upwardly out of the locking position to unlock the door. The same lock member acts in both the open and closed positions of the door by way of cooperation with strike plates on the door panel and an extension member projecting therefrom. The strike plates are shaped to return the lock member to a ready state for automatic locking during opening and closing of the door.

Described herein is an animal handling device in the form of a cattle crush with automated headbail capture, back bar operation and positional sensing along with methods of use thereof. The crush and method offer automation for functions that in the art have been largely manual and inherently labour intensive, physical and even potentially dangerous for the operator and/or animal.

A cart enabling a single person to pull a livestock chute across the ground. The cart includes a bar having a handle and wheels provided at opposing ends. The bar includes first and second members pivotally engaged together. A crossbar pivotally mounted on the bar includes first and second arms configured to engage handles on a lower front end of the chute. When the bar is in a collapsed position, where the first and second members are disposed at an angle to each other, the first and second arms are insertable into the chute handles. When the bar is moved to an erected position, where the first and second members are aligned along the same plane, a force is applied to a footrest on the bar. The arms lift the front end of the chute off the ground and the cart's wheels move under the front end of the chute.

An animal restraint system includes an arm clamp having a clamp body, a tether, a tether clamp, and a tether connector. The clamp body affixes to a securing arm at or below the animal's head and includes a tether anchor and a tether guide. The tether has a first tether end coupled to the tether anchor, a second tether end, and a middle section forming a loop, with a first loop side extending from the first tether end and a second loop side extending from the second tether end through the tether guide. The tether anchor and the tether guide are positioned to maintain substantial alignment between the first and second loop sides when the loop is tensioned. The tether clamp divides the loop into a primary and secondary loops and maintains a size of the primary loop, and the tether connector is slidably coupled to the primary loop.
