Description

Animal feeding cage for experiments

Technical Field

The application relates to the technical field of animal raising cages, in particular to an experimental animal raising cage.

Background

The experimental animal is an animal which is artificially fed, carries out control on the microorganism, has definite genetic background or clear source and is used for scientific research, teaching, production, verification and scientific experiments. As experimental use of cats, dogs and primates is increasingly limited by society and legislation, small pigs are becoming a good choice for experiments to replace such animals.

As a common experimental animal in biomedical research and medical instrument development, the miniature pig can meet the requirements of large animal experiments such as new medicine development, gene editing, gene therapy and the like. Miniature pigs have many advantages, including high similarity to humans in anatomy, genetics, physiology and organ size, early sexual maturation (4-6 months), short and fast breeding cycle, multiple fetuses, and the phenotype of the constructed pig disease model being more similar to human disease, with the advantage of fully sequenced pig genome to create pig models of genetic and rare diseases.

Currently, CDE (national drug administration drug review center) has increasingly accepted and approved preclinical experimental data generated by mini-pigs for new drug and gene therapy IND approval.

On the basis, the market demand for the small pig raising cages for experiments is also more and more abundant due to the wide application prospect of the small pigs. The traditional small pig rearing cage can not meet the requirements of standardized rearing and breeding of experimental animals. For example, the patent application document with the publication number of CN113907012A discloses an experimental miniature pig raising cage which comprises a supporting frame, a manure leakage plate, manure trays, fences and detachable side fences, wherein the manure leakage plate is clamped at the bottom of the supporting frame, manure leakage holes are formed in the manure leakage plate, the manure trays positioned below the manure leakage plate are slidably arranged on the supporting frame, the fences are fixedly arranged on the front side and the rear side of the supporting frame, and the detachable side fences are slidably arranged on the left side and the right side of the supporting frame. Through can dismantling the side rail, according to raising needs, withdraw or insert and put in the side rail dismantled on the adjacent side of two rearing cages of juxtaposition, with two or a plurality of rearing cages inside intercommunication, the suitability reduces or enlarges the pig and only breeds the space, can practice thrift the space and reduce the cost of raising furthest, simultaneously, through setting up excrement leakage board and excrement dish, the pig only excrement in the quick discharge rearing cage guarantees that the rearing environment is clean and tidy, makes the minipig can healthy growth. But this rearing cage wholly is metal network structure, guarantees the temperature in the rearing cage through setting up the heating lamp, avoids small-size pig to catch cold and ill, but the heating lamp influences animal sleep quality night, and top installation heating lamp, if animal stress beat, collide fragile heating lamp. In addition, the side fence of the rearing cage is a compact metal strip, which limits the communication between the miniature pigs and surrounding animals, influences the field of view of the animals, is unfavorable for the perception of people to enter and exit, and can cause stress and frightening of the miniature pigs. In addition, the feces in the rearing cage are easily accumulated on the bottom plate, are difficult to discharge, and have an influence on sanitation.

Therefore, if the experimental animal raising cage can be provided, animal metabolism and communication are facilitated, and the experimental animal raising cage has popularization and application values.
