Methods Before harvesting, the hair around the external genitalia of male rabbits must be shortened. In particular, the variety used for wool should be noted to facilitate sperm retrieval and reduce semen contamination.
Prepare a rabbit for male rabbits to climb, such as using a estrus female rabbit as a rabbit, to better increase the rabbit's libido.
When the sperm is collected, the female rabbit is caught in a male rabbit cage to allow the male rabbit to climb. The sperm extractor uses one hand to grasp the female rabbit's ears and neck, and the other hand holds the fake vagina and extends to the female rabbit's hind legs. Between the vulva. When holding a false vagina, the hand should preferably be 0.5 cm larger than the false vaginal opening, especially when using a thin tube as the outer shell, so as to avoid damaging the male rabbit's penis due to the false vaginal opening. At the same time, the fingers can feel the direction of the male rabbit's penis, in order to adjust the position and angle of the fake vaginal opening, to meet the penis into the false vagina. As long as the temperature and pressure are suitable, the male rabbit moves forward and it means ejaculation.
After the ejaculation, the male rabbit curled up to the side of the hind limbs, and most of the male rabbits also issued a cry, indicating the end of ejaculation.
The sperm extractor immediately retracts his hand and puts the false vaginal mouth upward to facilitate the passage of semen into the spermatic duct, and the hot water in the false vaginal cavity is removed. The spermatic duct is removed and the sperm collection is completed.
The amount of ejaculatory ejaculation in rabbits depends on the size of the body and the level of feeding and management. Large body size, high feed nutrient levels, and rational use of male rabbits, especially when estrus female rabbits are used to extract spermatozoa, male rabbits have more ejaculates, and vice versa. The amount of ejaculation is also related to the variety. Normal male rabbits each ejaculate 0.5 to 2.5 ml.
Precautions The most critical issue in collecting male rabbit sperm is the temperature in the false vagina. If the temperature is low, the male rabbit is not easy to ejaculate. If the temperature is too high, it is easy to injure male rabbit penis, and it is easy for male rabbits to develop high-temperature sperm extraction. Evil, and semen produced at high temperatures (above 45°C), quality will be affected, so special attention should be paid.
