Description

DETAILED DESCRIPTION OF THE INVENTION ``Industrial Application Field J'' The present invention relates to a method for raising laboratory animals and an apparatus therefor.

``Conventional technology'' Previously, experimental animals were kept in a breeding unit fixed on the floor in parallel, feeding was carried out in the same cage, and weight and other measurements were taken out of the cage by hand, so records were kept in memo format. However, it has been difficult to accurately and quickly measure the condition of the animals and to keep them under uniform conditions.

``A point to be solved by the present invention'' The purpose of the present invention is to easily carry out automatic rearing and automatic measurement of experimental animals under uniform conditions.

"Procedures and Means for Solving Problems" The present invention is characterized by moving the animals in the breeding section into a measuring box, feeding them in the box, measuring their weight, body temperature, etc., and then returning them to the breeding cage. It consists of experimental animal breeding methods and equipment.

``Effect'' Therefore, place one experimental animal between the front and rear lids in the breeding section,
With the opening of the measuring box facing the front end of the breeding cage, extend the removable arm toward the rear, grasp the front and rear lids with the same arm, and retract the reading box forward (into the measuring box) to measure the distance between the front and rear panels. The animal is housed in a measurement box and placed on a weight measurement floor to have its weight measured and its body temperature measured by a body temperature measurement sensor. After being fed by the metered feeding device installed on the white side of the feeder in the feeder, the arms move backwards and return the front and rear lids to the front and rear ends of the feeder. It comes off and shrinks the circular reading into the measuring box. The measuring box then slides and stops at a position that matches the next breeding cage, and the same operation as described above is repeated. The above measurement results are recorded in a recording device by a signal. ``Example'' A large number of breeding cages 3 are fixed horizontally in several tiers along both walls on the floor 2 of the livestock shed 1. Rails 4.4 are laid in the parallel direction in the central passage.

The cage 3 has a front end on the center passage side and a rear end on both side walls, and horizontal guide grooves 5.5 formed on both sides of the cage 3 and horizontal projections 7.7 provided on the top and bottom of the rear lid 6. is slidably inserted, and the protrusion 7.7 is made to protrude to the outside of the cylinder 3. Further, at the front end of W3, a front cover holding ring 8.8 protrudes from the front end of the guide groove 5.5, and horizontal projections 10.10 provided on the upper and lower sides of the front M9 are removably held by the holding ring 8.8. It is something to do. As shown in FIG. 5, this clamping ring 8.8 has a guide opening 8 formed at its front end, through which the projection 10 can be moved in and out. Then, a traveling trolley 12 is mounted on the front row 4.4 between which experimental animals 11 such as rabbits can be kept between the front and rear lids 6.9 of the rear chamber 3. The direction guide groove 14 is provided so as to be freely rotatable by 180 degrees and can be raised and lowered, and the opening at one end of the guide groove 14 is made to face the front end of the li3. Shaped measurement sensor 16 (based on infrared body temperature measurement sensor, etc.) and metered feeding device 17
etc., and detachable arms 18.18 for the front and rear lids 6.9 are provided at the four internal corners of the cover 14, as shown in FIG. At the tip of this arm 18, l8Fi, a gripping finger 19 (having an air chuck,
A gripping finger zO that can be opened and closed for gripping the horizontal protrusions 10, 10 of the front lid 9 is provided in the middle of the inner surface of the rotation reader 18, and the cylinder 18 can reciprocate in the front and rear directions. Quantitative feeding device 17tfi When the feeding device 21 installed in the forefoot 9 is stopped at the back of the measuring circuit 14, the lower end opening of the feed supply hopper 22 is provided directly above the feeding device 21 as shown by the imaginary line in Figure 6. Same hopper 22
An electromagnetic on-off valve 24 is provided in the funnel tube 23 to control the supply time and measure the supply amount based on the same time. In addition, what is indicated by 25 in the figure is a supply vibrator, 26 vertically rotating posts, and 27
is the feed lower limit level switch, 28 is the surveillance camera, 29
IIi electricity distribution operation panel, a 30-piece shipping table, 31 a excrement carrying conveyor, a 32-piece screw punch for sliding the stand 13, and 33 a sliding rail for the stand 13.

"Effects" Since the present invention is based on the above-described method and apparatus, quantitative feeding, weight measurement before and after feeding, and measurement of body temperature, etc., can be performed accurately, quickly and evenly on the experimental animals 11, and the experimental animals 11 can be very easily and easily fed. This allows for equal rearing of the animals.
