Description

The invention relates to an experimental animal cage with an automatic feeder for small animals, especially rats.

Experimental animal cages of various types are known for various purposes.

However, the known cages can only be used for examination to a limited extent the oral self-administration behavior of small animals.

For behavioral toxicology studies with questions such as self-administration and dependency development, Aversity and habituation, cognitive and regulatory skills, tolerance determination, etc. in research and. teach However, specially constructed cages are required for public and private carriers.

Di «? Cages have to be a little elaborate, identical allow exact and largely error-free and maintenance-free routine tests to be carried out over a long period of time.

In Fig. Ib it can be seen how the water bottles in the free space are arranged.

Lid and cage container are through in the usual way rigid clamp on the rear and a clamp that can be opened to the front on the front edge of the container connected.

The automatic feeders shown in Fig. II with a rounded base for better trickling of the feed point at their On the back wall on the left or right of the feed chute a vertical support plate, which has the shape of the lid recess and at its lower edge an angle is at right angles = is brought, which rests in the slope of the lid recess and deß holds the automatic feeder in a vertical position. On on the front edge of the angle there are two pegs that grip into the grille of the lid and the automatic feeder lock with it. The support plates attached to the left or right lead to two versions of the automatic feeder, which are mirror images of each other and therefore cannot be confused. Due to the support plate, the automatic feeder is standing free when it is not hung in the cage. Through this

With the cage according to the invention you can easily Assign individually sitting test animals to a differently composed food and / or liquid supply expose.

The advantages of the cage according to the invention are in particular in the fact that the living space of the test animals is significantly increased by the height of the lid, that the development a positional preference due to the closely spaced arrangement the feeding points in the middle of the cage prevents the feed scattering rate due to the increased position of the feeding points Reduced to a minimum above the bottom of the cage and thus the contamination of the feed by the test animal It is suppressed that the feed is constantly at the eating point due to the loose locking of the automatic feeder trickles out that the automatic feeders and the water bottles are easy to remove without moving the entire cage. *
