Artificial insemination section semen straw small goblets
Artificial insemination is an important measure to develop animal husbandry in China. At present, most of the semen used in artificial insemination in China is thin tube frozen sperm. The use of fine tube frozen sperm improves the utilization rate of excellent males, promotes the speed of variety improvement, improves production performance, is not limited by region and time, and can greatly reduce the number of male animals and save money. Compared with granular frozen essence, the thin tube frozen essence is convenient to use, and can reduce the waste of semen and microbial contamination, and the conception rate is high, and the fine tube frozen essence can be fully utilized, and the storage and retrieval are A key part.
The storage of frozen semen cannot be removed from the cold source and must be stored below the dangerous temperature zone where the sperm is frozen. Since the temperature of liquid nitrogen is much lower than that of the sperm freezing dangerous temperature zone, it is easy to use and it is reliable to store frozen semen, so it has been widely used. Frozen semen can be stored in liquid nitrogen for a long time, and sperm motility does not decrease.

When frozen semen is stored in liquid nitrogen, it is necessary to first dispense the fine tube into the thumb tube. The traditional method of tube filling is to put the thin tube frozen into the thumb tube by tweezers, which is inefficient, and the thin tube frozen sperm needs to leave the liquid nitrogen during the tube filling process, and the sharp temperature rise after leaving the liquid nitrogen will cause freezing. The vitality is reduced. Moreover, the conventional thin tube frozen and refined dispensing method sometimes causes the problem that the operating tool and the frozen essence can not be taken out at the bottom of the liquid nitrogen tank during operation, resulting in serious waste of resources. This requires a lot of labor for laboratories that produce thousands of frozen sperm per day, and the long-term exposure to volatile liquid nitrogen can cause harm to the body.
The device and the method for quickly dividing the thin tube frozen sperm into the thumb tube can quickly divide the thin tube frozen sperm into the thumb tube, and the dispensing process does not need to leave the liquid nitrogen, thereby improving the quality of the frozen essence. And work efficiency, is conducive to the health of the staff, suitable for promotion in the field of artificial insemination technology.
