Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a feeder accessory. More specifically, when feeding animals using a wide-mouthed stationary feeder, there are no problems such as animal excrement being mixed inside the feeder or food spilling out of the feeder to the outside. Related to dexterity accessories.

[0002]

2. Description of the Related Art Conventionally, when a test compound is mixed with a powdered feed and administered to an experimental animal such as a mouse, a wide-mouthed stationary glass feeder (hereinafter referred to as a feed bottle) has been used. Is used.

[0003] When feeding is performed using a conventional feeding bottle, the feeding bottle is filled with a predetermined amount of powdered food, and the feeding bottle is placed on the floor inside a cage (ori) containing a mouse. As a result, the mouse inserts its mouth into the opening at the top of the feeding bottle and eats the food by itself, so-called free-feeding is performed.

[0004]

However, the conventional feeding bottle has a low height because a mouse eats food by itself through an opening on the upper surface. This makes it easier for the mouse to ride on the feeding bottle.

When a mouse rides on a feeding bottle, there is a case where excrement (feces or urine, etc.) or floor bedding (wood scraps, etc.) is mixed in the food in the feeding bottle. In some cases, the loss of food is increased when the mouse scrapes the food in the feeding bottle to the outside with the foot.

[0006] For this reason, since it is not possible to accurately determine the amount of food, there is a problem that the accuracy of the experiment is impaired. Also,
There is also a problem that a large amount of labor is required for work on experimental management, such as labor and time required for removing contaminants for measuring the amount of residual food. In addition, there is a problem that it takes time to clean the feeding bottle and the cage.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and eliminates problems such as the incorporation of animal excrement and the like in the feeding bottle and the spilling of food from the feeding bottle. It is an object of the present invention to provide an accessory for a feeder that does not impair the accuracy and does not require labor for an experiment management operation and a cleaning operation.

[0008]

A feeder accessory according to the present invention is a feeder accessory which is mounted on an opening of a feeder having an opening on an upper surface side, wherein the feeder has an opening. A connecting portion for connecting to the vicinity and a dividing portion for dividing the opening into a plurality of regions, and the dividing portion has a size that does not allow an animal fed through the opening to ride thereon. In this way, the animal is divided into a plurality of regions, and the height of the divided portion is such that the animal cannot ride on it.

It is preferable that the divided portion is formed by combining a plurality of plate-like members in a well shape.

[0010] It is preferable that the divided portion is inclined so as to be directed toward the center of the opening of the feeder as the outer peripheral portion thereof is directed upward.

It is preferable that the connecting portion is formed by cutting a part of a lower end of the plate member.

It is preferable that the connecting portion is formed by cutting a part of a lower end of the plate-like member into a slit shape that opens downward.

When the accessory for a feeder of the present invention is used, a conventional feeding bottle is used by connecting a connecting portion near an upper opening of the feeding bottle.

An animal such as a mouse can put its head in a plurality of areas of the opening divided by the dividing part and freely ingest food as in the conventional manner.

On the other hand, even if an animal such as a mouse tries to get on the feeding bottle, the dividing portion divides the opening into an area where the animal to be fed cannot ride, and the height of the dividing portion is high. Is so high that animals cannot ride on it, it cannot be put on the feeding bottle. Therefore, there are no problems such as animal excrement being mixed into the feeding bottle and food being spilled from the feeding bottle.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an accessory for a feeder of the present invention (hereinafter referred to as an accessory) will be described in detail with reference to the drawings. FIG. 1 is a perspective explanatory view showing an embodiment of the accessory of the present invention, and FIG. 2 is a top view of the accessory of FIG.

The accessory 1 shown in FIG. 1 is used by being attached to an opening 3 on the upper surface side of a feeding bottle 2 conventionally used.

As the feeding bottle 2, a commercially available wide-mouthed stationary bottle is used. The feeding bottle 2 is a feeding bottle main body 4 which is a glass cylindrical container for storing the food, and the feeding bottle 2 is for preventing the bait from being scraped out and for preventing the mouse head and legs from falling into the feeding bottle main body 4. And a lid 6 for pressing the mesh-shaped middle plate 5. The lid 6 has the opening 3 formed in the top plate 6a, and an internal thread (not shown) for screwing into the external thread 4a on the feed bottle main body 4 side is formed on the inner peripheral surface. I have.

Although the size of the feeding bottle 2 for a mouse is not particularly limited in the present invention, for example, the outer diameter is about 80 mm, the height is about 35 mm, and the opening 3 on the upper surface.
Has an inner diameter of about 63 mm.

As shown in FIG. 1, the accessory of this embodiment has a connecting portion 7 for connecting to a lid 6 around the opening 3 of the feed bottle 2, and the opening 3 has a plurality of areas. And a dividing unit 8 for dividing.

The dividing section 8 divides the opening 3 into a plurality of areas so that the opening 3 is not large enough for a mouse to ride on. The size (maximum length) of each area varies depending on the size of the mouse to be fed, but usually, the body length L of the mouse
The target is about 16% or less. In other words, the opening 3
For example, as shown in FIG. 2, the divided individual regions are set so that the head of the mouse M can enter, but the trunk does not enter. Therefore, the mouse M can enter the head from the direction of the arrow A or the arrow B into the plurality of regions of the opening 3 divided by the dividing unit 8 and can freely eat food as before. However, even if the mouse M tries to get on the feeding bottle 2, since there is no head space when the accessory is installed in a commercially available cage, the feeding bottle 2
Can't get on.

Moreover, as shown in FIG. 1, the dividing section 8 has a height h such that the mouse M cannot ride thereon, and therefore cannot be placed on the feeding bottle 2.

Therefore, the mouse M cannot be put on the feeding bottle 2 by the accessory 1, so that the excrement of the mouse M may be mixed into the feeding bottle 2 or the food may be spilled from the feeding bottle 2. Is eliminated.

If the height h of the dividing part 8 is about 53 mm, the mouse cannot ride on the dividing part 8 and the feeding bottle 2 to which the accessory 1 is attached is easily placed on the skewer in which the mouse is stored. There is an advantage that it is easy to put in and out.

The dividing portion 8 shown in FIG. 1 is formed by assembling a plurality of plate-like members in a well shape and then standing upright, so that it is easy to manufacture and has sufficient strength. The incorporation of a punching plate of the same type facilitates assembly, can be easily removed, and has effects such as easy cleaning.

Since the outer peripheral portion 8a of the dividing portion 8 is inclined toward the center of the opening 3 of the feeding bottle 2 as going upward, the mouse slides on the inclined surface and is placed on the accessory. By making it difficult to ride, there is no mixing of excrement and bedding into the feeding bottle, and thus there is an effect that measurement of the amount of remaining food becomes easy.

Since the connecting portion 7 is formed by cutting off a part of the lower end of the plate-like member, there is an effect that it can be easily formed.

Further, the connecting portion 7 has a slit 7a for opening a part of the lower end of the plate member downward.
Since it is formed by notching, it can be easily formed, and by fitting the lid 6 to the slit 7a, the accessory 1 can be firmly connected to the feeding bottle 2. Particularly preferred.

When the accessory 1 shown in FIGS. 1 and 2 is manufactured, for example, the connecting portion 7 is formed by cutting out a part of lower ends of four plates made of stainless steel and having a height of 67 mm and a length of 98 mm. Formed, then the plate is 17mm on one side
It is produced by fitting a plate into a well so as to form a square pillar, and then welding the plates together.

Although the height of the entire accessory 1 is not particularly limited in the present invention, the fall of the fall is considered by the connection of the connecting portion 7 to the lid 6.

Experimental Example As for animals, 30 Crj: CD-1 (ICR) mice, 4 weeks old (male), were acclimated for 1 week (semibarrier system, temperature 23 ± 1 ° C., humidity 55 ± 5%, ventilation frequency) 15 times / hour, 12 hours light / dark), then 5 groups per group in the same environment
Group of feeding bottles equipped with the well-shaped accessory of the present example (Example), and three groups of commercially available feeders (dome type, box type, cylindrical type) Breeding) and a conventional method of feeding bottles alone, a total of seven groups were studied. The “dome type” is a stainless steel feeder with a shape similar to a glass feeding bottle, and a dome-shaped attachment is attached.The “box type” is a square box type The inside is divided into about three places by a partition plate. The “cylindrical type” is a cylindrical feeder in which the food falls from the upper surface to the lower part as the mouse consumes the food. Is coming.

The feed was CE-2 (Clea Japan).
Was freely ingested, and drinking water was freely ingested by automatic water supply. The study period was 7 weeks, during which the body weight, intake and the number of contaminants (excreta and bedding (alpha dry)) in the feeder were measured twice a week (Monday, Friday). In addition, the degree of contamination of the feeder was visually observed at the time of measurement.

Table 1 shows the overall evaluation of various feeding bottles based on the experimental results.

[0034]

[Table 1]

The following was found from the experimental results.

1. There was no difference in weight gain between the well type, the feeding bottle only group and the dome type. However, the box type showed a slightly lower value.

2. The amount of food per animal / day was 5 to 5 per group.
6 g, but the group with only feed bottles weighed 6-8 g.

3. The number of stool and bedding was clearly reduced in the well and dome type compared to the group with the feeding bottle alone, but the amount of stool mixing in the box type was similar to that in the group with the feeding bottle only.

4. The number of feces and bedding mixed was clearly reduced in the group equipped with the accessory of this example (Example) as compared with the feeding bottle group. In addition, the contamination of the feed bottle was reduced, and the cleaning became easier.

As a result of comprehensive evaluation of the above results, the feeding bottle provided with the accessory for the well type feeder was the best.

In the above embodiment, a mouse was described as an example of an animal fed using a feeder, but the present invention is not limited to this, and the size of the accessory is not limited to this. By changing the shape and shape, it is possible to apply the accessory of the present invention to a feeder used for various experimental animals. For example, the feeder of the present invention can be applied to feeders used for experimental animals such as rats, hamsters, and gerbils that are currently widely used for experimental research.

[0042]

According to the present invention, when feeding an animal using a wide-mouth stationary feeder, animal excrement or the like may be mixed into the feeder, or the feed may be fed from the feeder to the outside. No defects such as spills. Therefore, the accuracy of the experiment is not lost, and the accuracy of the experiment is improved.

Furthermore, since the amount of contaminants is reduced, work for experiment management such as reduction of the time and labor required for measuring the amount of residual food and cleaning work of the feeding bottle and the cage are relatively easy, and no labor is required. There is an advantage that labor can be greatly reduced.
