1. Make a fake vagina: The general model is (it may be unclear, you can search for relevant videos to learn). First, the diameter of the plastic cylinder is about 10cm, with one end closed and warm water inside; Second, the inner tube, which is made of rubber, is also cylindrical. Insert it into a plastic tube, tie one end tightly, fill the tube with water for about 50 degrees, and buckle the inner tube backwards on the tube to form a "I"-shaped false vagina.
2. Sperm collection: grab a female rabbit in estrus, stimulate the male rabbit first, and when there is fear of cross-behavior, grab the female rabbit, put the false vagina on her genitals, obliquely downward 30 degrees, and slightly raise her hips to cater to the male rabbit's penis, and quickly establish a false vagina after mining.
I have a video and can send it to you for free if necessary!
