A multi-pet locking-head-and-locking-tail-push-rod pet crate comprises: a handle bridge, a handle channel molded inside the handle bridge for containing grooming tools, handle clasps respectively molded in the handle bridge for fastening poop bags thereto, a top panel, a bottom panel, a left panel, a right panel, a front panel, a rear panel, at least one divider, panel-locking hooks and clamps for hooking and clamping the panels together, a slanted tray for draining urine, urine-storing gutters and ridges molded around the tray for supporting pet paws and for keeping pets away from urine, top and bottom low-friction rails welded to the front panel, multi-position door-glider-locking recesses formed in the bottom low-friction rail for locking the auto-indexing multi-position door gliders and for adjusting horizontal or slanted and stationary or moving positions of the auto-indexing multi-position doors, first and second auto-indexing multi-position doors inserted between the top and bottom low-friction rails, first and second auto-indexing multi-position door gliders respectively cast to the first and second doors for horizontally or slantedly being locked in the multi-position door-glider-locking recesses to horizontally or slantedly lock said first and the second doors in multiple horizontal or slanted and stationary or moving positions, first and second push-rods respectively and movably attached to the first and second doors, first and second door-locking push-rod heads respectively cast to the first and second push-rods for locking the first and second doors together, and first and second multi-position door-locking push-rod tails respectively cast to the first and second push-rods for locking and aligning the first and second doors to the front panel and for adjusting multiple positions of the first and second doors.

A hollow polymer stall divider for use in a barn permits lateral flexing when a cow presses against the stall divider while the stall divider asserts a lateral force against the cow to urge the cow to move into a proper position between adjacent stall dividers without causing injury to the cow. The polymer stall divider can be formed of a single polymer material having a unitary density throughout. Alternatively, the polymer stall divider can be formed of multiple sections of different densities of polymer material, and different types of polymer material. The different sections of polymer material can be plastic welded together or connected by plug members inserted into the adjoining ends of the sections and secured with adhesives or other bonding material to form line blanks that can be heated until softened sufficiently to be bent into a proper shape within a pre-formed mold.

Free stall systems having free stall units arranged in a substantially parallel relationship having coated rail members. The coated rail members comprising an elongated fiberglass material manufactured by grinding a starting fiberglass material prior to a coating being applied. The starting fiberglass material can be reclaimed and reused from other industries such that the fiberglass material may be cut to remove unwanted metal end portions and/or cut to a desired size prior to the grinding and coating steps. The coated fiberglass material can be coated with a UV-resistant material or other coating to maintain the longevity of the fiberglass member during its use. The coated fiberglass apparatus may be utilized in free stall systems, gates, fencing materials and other applications where a solid fiberglass rod or hollow fiberglass tube having a desired coating is desired.

A livestock living quarter for a transport trailer, such as a livestock trailer, provides livestock stalls and mangers inside the trailer. The living quarter includes at least one stall for a livestock animal, the stall defined by a chest wall, an interior wall, and a front wall set parallel to the interior wall. A second stall may be provided, with the interior wall of the first stall providing a divider wall between the first and second stalls, and acting as a front wall of the second stall. The stall divider may be pivotable to allow for entry of a livestock animal into the stall. A manger is disposed in front of the stall for storage of feed that is accessible to the livestock animal in the stall. Optionally, a water trough is accessible at the manger, and other spaces may provide living quarters or facilities for an operator.

A stand-alone chamber or multi-chamber inhalation system has at least two alternative vaporized test liquid supply systems for passive or self-administered delivery of vaporized test fluid and air to one or more test chambers, which can be passive or restraint chambers, based on operator selection of delivery on and off times in a passive mode or actuation of an actuator in the chamber by a test animal in a self-administered mode. In one case, a multiple inhalation chamber system has two or more separate test fluid delivery systems and provides options for selective passive uniform drug delivery to multiple chambers or selective delivery of two or more different drugs to different groups of chambers from different delivery systems so that two different drugs or different concentrations of delivered drugs can be tested simultaneously.

A front element for stalling an animal in a free stall, that is better suited than earlier devices to the morphology and movements of the animal to be contained, helping guide the animal when it is positioning itself, standing up and/or lying down in its free stall. Such a front element can be implemented in a pair in a front structure, in order to delimit the internal space I of said free stall.

Disclosed is a flexible tubular device including a tubular wall that delimits a sealed chamber intended to be filled with a fluid. The tubular wall includes an elastomer matrix into which at least one reinforcement ply delimited by two longitudinal portions is incorporated. The at least one reinforcement ply has the general shape of a sleeve that extends inside the tubular wall to surround the sealed chamber; and the two longitudinal portions of the at least one reinforcement ply are juxtaposed relative to each other. Also disclosed is a rearing enclosure including such a device, and also a method for manufacturing the latter.

An improved biosecurity livestock confinement crate system for safely confining and farrowing livestock. The confinement crate system improves the safety of the livestock and the user. The confinement crate system includes a containment area which houses an animal and is adjoined, and separated, by a rib structure in the configuration of a Flying-W. This configuration protects offspring of the animal in the adjoining safety area from being injured or killed.
