Efficient manure collecting device for experimental rat group

Abstract

The invention relates to an efficient manure collecting device for an experimental rat group. The efficient manure collecting device comprises a rat cage, collecting drawers and supports and is characterized in that the rat cage comprises two-two-opposite single cages, multiple cages are located in one row, two rows of the cages are connected together in a planar manner, the upper portion of eachcage is provided with a cage cover, the bottom of each cage is a hollow cage bottom grid, and the left side, the right side, the front side and the rear side of each cage are surrounding plates; the supports are formed by a plurality of small box type spaces which are arranged at intervals, the support inner side of each small box type space comprises a plurality rows of clamp grooves, the clamp grooves are vertically arranged, and the clamp grooves correspond to the protrusions at the bottoms of the collecting drawer and used for fixing the collecting drawers; each row of clamp grooves of onerow of support corresponds to one collecting drawer, each collecting drawer comprises a plurality of small drawers parallelly connected by handles and connecting rods, the number and positions of thesmall drawers correspond to those of the single row of cages, the lateral side of each small drawer is an oblique surface which is high in inner end and low in outer end, two rows of urine leakage ports are formed in the bottoms of the outer sides of the small drawers, and urine collecting trenches are arranged below the urine leakage ports. By the efficient manure collecting device, rat group manure collecting and cleaning efficiency during large-scale experiments can be increased effectively.

Description

technical field [0001] The invention belongs to the technical field of biological experiments, and in particular relates to a device for efficiently collecting feces of experimental mice. Background technique [0002] Gut microbiome research is an extremely important field in life sciences, and collecting rat or mouse feces is a necessary operation for studying gut microbes. Due to the needs of the experiment, several rats or mice are usually kept together in cages. When feces need to be collected, each one is placed in a metabolic cage separately, and then the feces are collected cage by cage. It has been found through long-term experiments that the existing feces collection device has the following disadvantages: it occupies a large area, and it is inconvenient to move the device when it is necessary to collect multiple animal feces at the same time; Shorten the time that the feces are exposed to the air as much as possible, and collect the feces into the collection tube ...

Problems solved by technology

It has been found through long-term experiments that the existing feces collection device has the following disadvantages: it occupies a large area, and it is inconvenient to move the device when it is necessary to collect multiple animal feces at the same time; Shorten the time that the feces are exposed to the air as much as possible, and collect the feces into the collection tube as soon as possible to seal the cap, while the existing device has only one feces collector for each cage, and the defecation time of the experimental mice cannot be determined, so it is necessary to check each cage several times. The feces collection of each collector is time-consuming and laborious; after collecting the feces, in order to prevent bacterial cross-contamination, the feces collection devices must be cleaned and disinfected one by one.

In particular, research on intestinal microbes often involves multi-factor grouping experiments. When the size of the experimental rat group increases to hundreds of experimental animals, the existing rodent feces collection device cannot cope with the collection and cleaning needs of a large amount of rat feces.
