Description

Technical Field

[0001] The present application relates to the technical field of animal breeding cages, and in particular to an animal breeding cage for experiments. Background Art

[0002] Laboratory animals are artificially raised animals with controlled microorganisms, with clear genetic background or origin, and used for scientific research, teaching, production, testing and scientific experiments. As the experimental use of cats, dogs and primates is increasingly restricted by society and legislation, miniature pigs have become a good choice to replace the above animals for experiments.

[0003] Miniature pigs are commonly used experimental animals in biomedical research and medical device development, and can meet the needs of large animal experiments such as new drug development, gene editing, and gene therapy. Miniature pigs have many advantages, including being highly similar to humans in anatomy, genetics, physiology, and organ size, early sexual maturity (4 to 6 months), short and fast reproductive cycles, multiple births, and the phenotypes of constructed pig disease models are more similar to human diseases. They have a fully sequenced pig genome to create pig models of genetic and rare diseases.

[0004] Currently, CDE (Center for Drug Evaluation of the State Drug Administration) has increasingly accepted and recognized preclinical experimental data generated by miniature pigs for the approval of new drug and gene therapy INDs.

[0005] On this basis, due to the broad application prospects of miniature pigs, the market demand for experimental miniature pig cages is becoming more and more abundant. Traditional miniature pig cages cannot meet the requirements of standardized feeding and breeding of experimental animals. For example, the patent application document with publication number CN113907012A discloses an experimental miniature pig cage, including a support frame, a manure-leaking plate, a manure tray, a fence, and a detachable side fence; the bottom of the support frame is clamped with a manure-leaking plate, and the manure-leaking plate is provided with a manure-leaking hole, and a manure tray located below the manure-leaking plate is slidably installed on the support frame, and fences are fixedly installed on the front and rear sides of the support frame, and detachable side fences are slidably installed on the left and right sides of the support frame. Through the detachable side fence, according to the feeding needs, the detachable side fences on the adjacent sides of the two cages placed side by side are pulled out or inserted, and the inside of two or more cages are connected, which can reduce or expand the pig feeding space, and can save the feeding space and reduce the feeding cost to the maximum extent. At the same time, by setting the manure-leaking plate and the manure tray, the excrement of the pigs in the feeding pen can be quickly discharged, ensuring a clean feeding environment, so that the miniature pigs can grow healthily. However, the cage is made of a metal mesh structure. A heating lamp is installed to ensure the temperature inside the cage and prevent the small pigs from getting cold and getting sick. However, the heating lamp affects the sleep quality of the animals at night. The heating lamp is installed on the top. If the animals jump or collide due to stress, the heating lamp is easily damaged. In addition, the side rails of the cage are tight metal bars, which limit the communication between the small pigs and the surrounding animals, affect the animals' field of vision, and are not conducive to their perception of people entering and exiting, which may cause stress and fright to the small pigs. In addition, feces in the cage easily accumulate on the bottom plate and are difficult to discharge, which affects hygiene.

[0006] Therefore, if a cage for raising experimental animals can be provided to facilitate animal metabolism and communication, it will have greater value for promotion and application. Utility Model Content
