Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a small animal breeding device for breeding small animals such as laboratory animals.

(Prior Art) Conventionally, as a device for breeding small animals such as laboratory animals weighing around 10 kg or less, a large number of breeding cages are mounted or suspended in a multi-stage arrangement on a stand fixed in a breeding room. It was hot.

Such conventional small animal breeding devices have the following problems.

(1) The pedestal that supports the cage has parts that cannot be cleaned, such as the underside of the pedestal and the inside of the sun, where dirt and insects can get in and cannot be removed, making it undesirable in terms of the breeding environment for experimental animals.

(2) When washing the upper part, the work is dangerous as the worker may have to climb on a stand and may be exposed to hot water while washing, and the lower part may involve bending over, lying on his stomach, twisting his neck, etc. Workability is difficult.

(3) You may be injured by hitting the corners of the stand.

(4) Washing puts a strain on your wrists, shoulders, lower back, and neck, resulting in unbearable fatigue and pain.

Therefore, a solution to this problem is, for example, a cage consisting of a plurality of rearing cages whose bottom surfaces are made of a mesh material that allows dirt to pass through, and a frame body with casters on which the rearing cages are placed side by side. The filth scraping member that slides on the floor of the rearing space scrapes off the filth on the floor while flushing water from the cleaning water nozzle along the top surface of the filth scraping member. A small animal breeding device (Japanese Unexamined Patent Publication No. 58-212729) that allows collection and washing to be carried out simultaneously without the need for human hands, and a excrement receiving device in which a water storage tray for excrement and urine is tiltably installed at the bottom of each breeding cage. A manure and urine processing device for an animal breeding machine (Special Publication No. 1973 −
Publication No. 17970) was known.

(Problems to be solved by the invention) However, the breeding devices disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 58-212729 and Japanese Patent Publication No. 44-17970 are mainly aimed at removing excrement and urine; However, the above-mentioned publication does not provide any explanation regarding the breeding cage itself, which is one of the important elements from the viewpoint of environmental hygiene of the breeding animals.

In other words, there have been no proposals for conventional rearing cages that are placed on or fixed to a pedestal and configured to be removable except for the front part. There is a problem in that the workability is extremely low, and the breeding apparatus disclosed in the above-mentioned publication is no exception. The reason why a breeding cage that can be assembled and disassembled has not been proposed is that this type of breeding device is for experimental animals, and monkeys in particular are strong and highly intelligent, so there is a risk that they will be dismantled. It is understood that this was due to the heat.

(Means for Solving the Problems) The gist of the present invention for solving the above-mentioned conventional problems is to include a plurality of rearing cages whose bottoms are made of net material through which excrement can freely pass through; The breeding cages are placed side by side on a pedestal, the pedestal is provided with casters for movement, and the pedestal is provided with a tray for receiving excrement under the cage, and the tray has a drainage port on the back edge side. A bucket connected to the drain opening of the saucer and tilted to one side is removably supported on the back of the pedestal, and is located on the back of each cage placed on the pedestal. A small animal breeding device comprising a water supply pipe removably supported on the back of a pedestal, and a water supply nozzle inserted into each of the cages in the water supply pipe,
The breeding cage includes left and right side plates, a back plate,
A front screen, a top screen, and a bottom screen, wherein ring metal fittings for hinges protrude from both edges of the left and right side plates, the back plate, and the front screen, and the left and right side plates, At the corners where the edges of the back plate and the front mesh abut each other, the ring fittings are arranged coaxially in the vertical direction, and a pivot is inserted into the ring fittings to connect the left and right side plates, the back plate, and the front side. The nets are connected in each cylindrical arrangement, and a stopper is attached to each corner of the top screen with a bracket so as to be freely removable toward the outside, and the stopper is made to protrude and is formed at the top of each of the pivots. The top net is assembled by inserting the top net into the ring portions, and protrusions are provided on the inner surfaces of the lower edges of the both side plates, the back plate, and the front net, and the bottom net is placed on the protrusions. The small animal breeding apparatus is configured by assembling the apparatus, and is characterized in that the trays are stacked in a plurality of tiers and are provided so as to be freely inserted and removed.

(Function) This small animal rearing device constantly supplies water to the water pipe during rearing, and supplies water to the reared animals through the water supply nozzle.

The excrement of the small animals being raised falls through the mesh material on the bottom of the breeding cage onto the tray, and the fluids flow down, but the solids remain on the tray, so the uppermost tray that contains the solids falls. are removed periodically and replaced by inserting the lower tray into the top row, and the removed trays are washed individually in a cleaning room separate from the rearing room.

If the breeding cage is dirty, move the animals in the cage to another empty cage, remove the tub and water pipe attached to the contaminated cage from the pedestal, remove the empty cage from the pedestal, and transfer it to the cleaning room. Then, disassemble the cage and thoroughly clean it.

By moving all breeding cages to another pedestal and transporting the empty pedestal to a cleaning room, the pedestal itself can be completely cleaned.
