Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical research and development experimental equipment, in particular to a rat mating experimental cage. Background Art

[0002] In non-clinical reproductive toxicity studies of drugs, rodents are often used for mating experiments to verify the effects of drugs on animal mating ability, or to use successfully mated rodents as experimental animals to demonstrate the effects of drugs on pregnancy and embryonic development in pregnant mice. In order to ensure the accuracy of the results in the experiment, it is necessary to clarify the conception time of the experimental mice. When preparing pregnant experimental mice, male and female mice are generally placed in the same mating cage, and the mating results are observed after a set time. If a vaginal plug is seen falling off from the female mouse in the mating cage, it proves that the female mouse is successfully pregnant and can be used for various experiments; if no vaginal plug is seen, the male and female mice need to be separated for the next mating. After searching: an experimental mouse mating cage with the authorization announcement number CN219781233U comprises: a cage body, the upper side of which is open; a partition component, which is arranged on the inner wall of the cage body, and when it is in a first working state, it is used to divide the cage body into two independent isolation spaces on the left and right; when it is in a second working state, the experimental mouse can pass through the two isolation spaces; and a cover body, which is arranged on the upper side of the cage body.

[0003] However, the above-mentioned experimental rat mating cage still has some shortcomings. Although the mating experimental cage can be divided into two spaces, the middle board is a solid wooden board without a through hole, so the female and male rats cannot have pre-contact before mating, resulting in a low mating success rate. It is also inconvenient to disassemble and assemble the food or water feeding cups, and it is inconvenient to clean them or add food and water. Therefore, we propose a rat mating experimental cage to solve the above problems. Utility Model Content
