Abstract

The invention provides a rabbit non-operative embryo transfer instrument, a method and an application thereof. The transfer instrument comprises an outer tube sleeve, an outer tube, an inner tube anda syringe. The rabbit embryo was inserted into the inner tube. Binding recipient rabbit, inserting an outer tube with an outer tube sleeve from the recipient rabbit's vagina until the tip of the outertube reaches the cervix of uterus; Pull out the outer sleeve outward so that the closed end of the outer sleeve is pierced by the tip of the outer sleeve. The outer tube is pushed so that the tip ofthe outer tube passes through the cervix, the inner tube is inserted into the tip of the outer tube, and the rabbit embryo in the inner tube is injected into the uterus with a syringe connected with the inner tube. The invention eliminates the injury and infection risk of the recipient rabbit caused by the operation, can quickly transfer the rabbit embryo into the recipient rabbit uterus, can improve the efficiency of the rabbit embryo transfer and the fetal birth rate, and is widely applied.

Description

technical field [0001] The invention belongs to the field of experimental animal applications, and relates to a non-surgical transplantation device and method for rabbit embryos used in the process of constructing model animal disease models and the like. Background technique [0002] Rabbit is an important model animal, very close to human in phylogeny. Rabbits are of great value in the research of lipid metabolism, atherosclerosis and other diseases. Interfering with drugs on rabbits, such as feeding rabbits with cholesterol to establish atherosclerosis models, is a very important model for studying lipid metabolism and atherosclerosis. Natural mutation selection to obtain disease model rabbits, such as WHHL and WHHLMI, and rabbits with specific genetic modifications through gene editing, which play an important role in elucidating the mechanism of disease, developing new drugs and new treatment options. So far, a variety of gene-edited rabbits have been reported. [00...
