How to tell a man from a woman?
It's difficult to tell the difference between the male and female rabbits. The sex of newborn rabbits can generally be identified by observing the shape of the genital hole and the distance from the anus. The hole is flat and slightly larger, and the female rabbit is close to the anus; The hole is slightly smaller, and the male rabbit is far away from the anus. From August after the rabbit was born to 10, the testis (testis) of the male rabbit began to grow. Grab the rabbit and touch the vagina near the anus with your hand. You will feel a piece of meat slightly larger than broad beans, which is a male rabbit and a female rabbit without meat. But the meat is big and small, so it is difficult to distinguish between male and female. There is no hair on the scrotum of adult male rabbits.
Rabbits grow up and start estrus. Male rabbits often beat the ground with their hind legs to make noises and chase the female rabbits. In this period, it is easy to distinguish between males and females. This behavior of the male rabbit is courting the female rabbit and showing his existence to the other party. Female rabbits can secrete a special smell when they are in estrus, and raise their tails and swing constantly, so that the secreted smell spreads outward, thus attracting male rabbits.
