である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic feeder for small animals, particularly for laboratory animals, and a feed suitable for the same.

Description of the Related Art Conventionally, when breeding experimental animals, the animals have been fed freely, resulting in obesity and various diseases, shortening their lifespan. This has become a serious problem when long-term experiments are required. In order to solve this problem, it is sufficient to limit the feeding, but it is inefficient to measure and feed a certain amount every day, because it takes a lot of trouble and time.

ている。[0003] In addition, even when feeding a pet kept at home, if the home is out of the house, feeding is not possible, so it is inevitable that a long absence will be avoided. Examination of the patent publications related to feeding small animals revealed that the following publications were picked up, but all of them were significantly different from those to be addressed by the present invention. Japanese Patent Application Laid-Open No. 6-70656 discloses a powder feeder which is intended to be rotated by the action of a small animal to scrape the powdered feed downward, but this is also required in the management of excessive feed supply. The problem remains.

である。Japanese Patent Application Laid-Open No. 8-114 discloses a feeder for small animals which is used for measuring the amount of feed and which is free from spilling, scattering and excrement. Therefore, the problem of the present invention cannot be solved. Japanese Patent Application Laid-Open No. 11-75599 discloses an accessory for a feeder, which is designed to prevent problems such as spilling of animal excrement inside the feeder.

Conventionally, cylindrical bait has been used as bait for experimental animals. However, in this case, when used in an automatic feeder, the food rolls horizontally but does not roll vertically, so that smooth feeding cannot be performed. The rolling form is spherical, which is used for dog and cat EP feed (E
(xpansion Pellet), but it was not used in animals such as rats and mice in which a hard diet is preferred because EP diet is too soft and unsuitable. . Therefore, the development of an automatic feeder and a feed suitable for the automatic feeder has been desired.

【発明が解決しようとする課題】小動物、特に実験動物
への自動給餌機の開発及び自動給餌機に適する餌の開発
を課題とする。An object of the present invention is to develop an automatic feeder for small animals, especially experimental animals, and to develop a feed suitable for the automatic feeder.

とで解決できることを見出した。Means for Solving the Problems The present inventors have made intensive efforts to solve the above-mentioned problems, and as a result, have made it possible to make the bait spherical and easy to roll, and at the same time, to solve the problem by developing the following automatic feeder. I found it.

有意の差が見出せなかった。[0008] First, the present inventors performed a comparative experiment with a conventional hard bait by giving a soft bait to an ICR mouse. As a result, they found that the mouse could be bred sufficiently even with a soft bait. That is, when a change in body weight, a change in food consumption, and observation of the mandible of an EP feed and a CE feed (a hard feed normally fed to mice and the like) were performed, a significant difference was found between the EP feed and the CE feed. I couldn't find it.

In the present invention, the term “spherical” includes not only a true sphere but also a shape close to a spherical shape that easily rolls.

Generally, it is obtained by blowing pressurized steam into powdered feed, passing through a die, and cooling and drying. However, since the bait used in the present invention is spherical, it has been subjected to EP processing. EP processing is a process in which extruder is used to apply heat, moisture and pressure to the raw material, to pregelatinize the starch in the blended raw material, and then rapidly release it into the atmosphere to expand it. Is to make porous pellets.

Holes 3 and 3 ′ are formed in the periphery of the rotating disk 2, and holes 4 are formed in the hopper. A pipe 5 into which bait falls is fitted directly below the hole 4. Rotating disk 2
Is inclined downward from the center toward the periphery, and stoppers 6, 6 'are provided in front of the peripheral holes 3, 3' formed in the rotating disk in the rotation direction. A small animal container such as a net basket 7 is installed at the end of the pipe so that the lower end of the pipe 5 receives the food and the small animal feeds.

In consideration of the state, the appropriate feeding amount to the small animal is calculated, and the rotation speed is determined. Usually, experimental animals are fed about 4 g of food per day. That is, the number of rotations of the rotating disk is adjusted so that 8 to 10 spherical baits can be given. In addition, depending on the purpose of the experimental animal, a low-nutritive diet may be given, and it is necessary to change the number.

特徴としている。Further, in order to make it possible to adjust the amount of feed in accordance with the weight of the experimental animal, the measurement of the weight of the animal and the amount of feed were linked. That is, only the slender bottom surface (11) of a container such as a net basket containing an animal is slightly separated from the net basket body, and the weight is measured with the experimental animal riding on the bottom surface of the net basket. In addition, the present invention is characterized in that the bamboo-shaped bottom surface of the container is supported by the frame, a tray (12) such as feces is provided in the frame, and a weight scale (13) is set on the lower surface of the tray. I have.

Further, since the feed is spherical, the feed tank is connected to an automatic feeder by a pipeline or the like, and the feed is automatically adjusted. It is also possible to feed the feed from the feed tank to an automatic feeder. The small animals in the present invention include experimental animals such as mice, rats, hamsters, and guinea pigs. Next, the present invention will be described in more detail with reference to the drawings.

Holes 3 and 3 'are drilled in the bottom of the hopper 4
When the bait 8 is communicated with the bait 8, the bait 8 falls into the pipe 5 fitted in the hole 4 and is housed in a container, for example, a net basket 7 disposed at the lower end. Further, the bait receiver 10 may be provided inside the basket in which the experimental animal is housed. The experimental animal 9 feeds on the bait 8 contained in the container, but since the rotation speed of the rotating disk 2 is controlled, the experimental animal cannot eat more than a certain amount.

It has a mountain shape with a gentle slope on the 3 'side.

る。The rotating disk 2 is inclined downward from the center toward the periphery, so that the bait 8 is gathered at the holes 3, 3 '. The number of holes 3, 3 'may be one,
The number may be two or more, but there is also a relationship with the feeding amount, and about two are preferable. The droppings fall into the tray 12 through the mushroom.

The weight is calculated by subtracting the weight of the dung, the frame, the saucer, and the feces from the measured weight.

量を決定する。To explain the operation of the present invention, first, a spherical bait is stored in a hopper. Next, the number of rotations of the rotating disk is appropriately calculated and set according to the purpose of the experiment, the type of animal, and the type of food. At this time, when the feed amount is varied according to the weight of the animal, the feed amount is determined by computer control in conjunction with the weight scale.

When the hole in the rotating disk and the hole in the hopper overlap, the food enters the pipe through the hole, It falls inside and is stored in the bait receptacle at the lower end. The small animal stored in the container feeds the food in the food receiver.
