Description

The utility model relates to agriculture, in particular to fur farming, specifically to cages for temporary and permanent keeping, mainly of foxes.

A cell battery for keeping fur-bearing animals is known, consisting of sections arranged in tiers and divided into cages of mesh canvases that form a floor, ceiling flooring, front, rear and end walls, sections are made up of cages made of two-tier, a young house adjoins the lower tier of the cage , made of heat-insulating materials, with a hinged roof, between the lower tier of the cage and the house, a manhole is made, located 1/2 the height of the lower tier of the cage, while above the lower tier of the cage, with a shift from the house of young animals, the upper tier of the cage, similar to the lower one, the ceiling of the upper tier is made with the possibility of opening, while between the tiers a manhole is made with the possibility of overlapping it (patent RU 127582 U1, publ. 05/10/2013). The utility model makes it possible to unify the cage battery for keeping fur-bearing animals, not to transplant animals after reaching a certain size in other cages, but to leave them in one cage section, but on different tiers.

The disadvantage of the known cell battery is that it is not intended for keeping large animals, and in addition, due to its small size, the latter does not allow the animal to sufficiently exercise motor activity.

The closest to the claimed cage - the prototype, is a standard cage for keeping female polar foxes and foxes with a shed system of keeping, which is a rectangular box measuring 2 × 1 × 0.7 m (hereinafter W × D × H), consisting of metal frames ( frame), upholstered with a welded galvanized mesh with a cell of 25 mm, divided by a partition into two compartments - a walk and a jigging cage, each of which has a door, a feeder and a drinker, and a stationary wooden nesting house, which is accessible during the breeding season. The cage is placed inside a universal shed at a height of 70-100 cm from the ground, with a span between the racks of 2 m and a frame spacing of 3 m (Afanasyev V.A., Pereldik N.Sh. Cellular fur farming. M., Kolos, 1966, S. 399).

Keeping animals in this type of cage is due to the introduction of the simplest mechanization of processes on the farm, reducing the cost of keeping animals and increasing economic efficiency.

The disadvantage of this design is the small size of the sections (compartments) of the cage intended for keeping the animal (no more than 1 m ² on the floor with a height of 0.7 m), which does not allow the animal to sufficiently exercise the motor activity necessary for the full formation of the body. In addition, when conducting research on animals, the small size of the cage limits the possibility of conducting experimental activities in a "home cage", including when a person is inside the cage, or associated with the placement of experimental installations and equipment. The small size of the cage implies the deposition of young animals from the mother, and then placement in individual cages, which implies capturing the animals and moving to an unfamiliar environment that can have long-term effects on animals, distorting their behavior in further research.

The task of the utility model is the development of a new, more advanced design that provides an optimal combination of standard conditions for mechanized maintenance of animals on a fur farm with conditions that provide sufficient motor activity for animals, as well as technical capabilities for experimental work with animals in a home cage.

The technical result is to expand the functionality of the cell for keeping and carrying out experimental work with animals.

The task is achieved by the proposed cage combined with an aviary.

FIG. 1 shows a general view of a cage combined with an aviary. FIG. 2 is a front view of the cage, and FIG. 3 is a side view of the cage.

The proposed design includes a cage (1) in the form of a rectangular box, constructed of a metal frame, consisting of two sections: a nest house (2) measuring 90 × 100 × 75 cm and a walk (3) measuring 90 × 100 × 75 cm, as well as a covered aviary (4), adjacent to the back wall of the cage. The cage and aviary form a single enclosed space. The nesting house is made in the form of a rectangular box made of wood with an opening top and an exit to the side of the walk. The cage is placed on a platform (5), measuring 180 × 100 cm (W × D), located at a height of 70-100 cm, installed on three metal triangular supports (6) to provide the possibility of mechanized cleaning of the space under the raised cages.

In the front wall of the walk (3), a door (7) and a rotary feeder (8) are made, and on the rear wall, at a height of 30 cm from the top, there is a shelf (9) measuring 90 × 30 cm, made of welded galvanized metal mesh. At the level of the floor of the rear wall of the walk (3), two manholes are made, right (10) and left (11), each measuring 25 × 30 cm, intended for lowering the animal into the enclosure. Lazes are equipped with plywood doors attached to hinges in the upper part, opening in different directions: the right manhole door (10) - inside the enclosure, the left manhole door (11) - inside the cage walkway (3). The doors (10, 11) and the rear wall of the walkway (3) are equipped with lugs (12), located coaxially, through which a metal bar from the outside is fixed in the open or closed position, both, and separately.

The exit from the nest house to the walk (3) of the cage (1) is made in the form of a manhole (13), 25 × 25 (W × H) cm in size, and is equipped with a horizontally sliding and locking flap door (14).

Covered aviary (4), measuring 300 × 200 × 200 cm, made of a frame upholstered with a welded galvanized mesh, equipped in its right part with a door (15), measuring 95 × 200 cm, consisting of two wings - a lower wing 40 cm high and an upper flap with a height of 160 cm. The door (15) of the aviary (4) is made with the possibility of opening from the outside from the side of the service passage of the shed in the direction "towards itself". In the aviary, at the level of the manholes from the walkway (3) of the cage (1), a wooden shelf (16) is made with a width equal to the distance between the outer edges of the manholes and a depth of 15 cm. An inclined ladder (17) is hinged to the long edge of the shelf (16) made of welded galvanized mesh, leading to the floor of the aviary. The ladder (17) and the shelf (16) are made with sides 10 cm high. On the wall of the aviary, above the shelf (16), there is a hook (18) to fix the ladder in the raised position. On the left and far walls of the enclosure, there are 3 wooden shelves (19), 30 cm deep, 150 cm long, located at a height of 85, 120 and 150 cm, respectively.

The claimed combined cell is used as follows.

The animal is placed through the door (7) into the walk (3) of the cage (1) installed on the platform (3), in which feeding and drinking, examination and necessary manipulations with the animal are carried out. The animal can be on the shelf (9) while resting, in addition, the presence of the animal on the shelf (9) facilitates manual removal of the animal from the walk (3) of the cage (1). Through the manhole (10), lifting the door with its muzzle, the animal can enter the cage (4) from the cage (1), and through the manhole (11) the animal can independently move from the cage (4) to the cage (3) cage (1). Moving from the shelf (16) along the ladder (17), the animal descends to the floor of the aviary (4). From the shelf (16), the animal can move to shelves (19) located at different heights along the walls of the enclosure. To prevent injury from falling, the floor of the aviary (4) is covered with straw and sawdust bedding.

To restrict the animal inside the walk (3) of the cage (1), use manholes with fixing doors (10, 11) that open strictly unidirectionally, one inward (11), the other outward (10) of the walk (3) of the cage (1). Animals quickly independently learn to open doors with their muzzle. Food bait is placed in the feeder (8) inside the walk (3) of the cage (1), the exit (10) from the cage (1) into the aviary (4) is fixed in the closed position with a rod through the lugs (12). The animal enters the cage and cannot get out, since the unsecured manhole door (11) opens only inside the cage (1), preventing the animal from getting into the enclosure (4). After that, the manhole door (11) is also fixed, completely blocking the passage between the cage and the aviary, and the animal in the walk (3) of the cage (1) can be removed through the door (7), or subjected to the necessary manipulations.

Feeding and drinking of the animal in the cage (1) is carried out by placing the feed in the feeder (8) manually, or with the help of feeding machines.

During the breeding season, the access hole (13) in the stationary nesting house (2) is opened by removing the valve (14). Inside the nesting house (2), the animal bears offspring and raises them. Care and inspection of young animals and females inside the nesting house (2) by the service personnel can be carried out from the side of the service passage of the shed, without requiring a passage inside the enclosure (4). If necessary, the manhole (13) can be closed with a latch (14).

If necessary, personnel can enter the enclosure (4) using the door (15). When going inside, you can open both both door leaves at the same time, and only the upper one, stepping over the lower door, which, thus, will serve as a barrier for animals inside, preventing escape.

A significant expansion of the space of the combined cage has a positive effect on the physical condition of the animals kept in the cage combined with the aviary. An increase in the range of motor activity leads to an improvement in the formation of the musculoskeletal system. The presence of a shelter (house), shelves, and items for manipulation inside the cage complies with accepted international recommendations for keeping animals in captivity and has a positive effect on the neuropsychic development of animals.

The use of the proposed combined cage will improve the conditions for keeping animals and expand the range of possible experiments carried out in a home cage, including with the use of experimental installations, special equipment and with the participation of humans. At the same time, the stressful effect on the animal from removal from the cage and transportation, which can have a negative impact on the results of the study, decreases.
