Technical Field

[0001] This utility model relates to the field of artificial insemination for pigs, and in particular to a hygienic insemination tube for artificial insemination of pigs. Background Technology

[0002] Artificial insemination of sows is an important reproductive technique in modern pig farming.

[0003] A good boar can only mate with a limited number of sows each year through natural mating, generally around 20-30. However, with artificial insemination, the semen can be diluted and used to mate with hundreds of sows, which can greatly maximize the genetic potential of the superior boar and accelerate the breed improvement of the pig herd. Artificial insemination of sows is performed through an insemination tube.

[0004] Appropriate insertion depth is crucial for the effective distribution of semen within the sow's reproductive tract, which helps improve fertilization success rate. Current artificial insemination procedures for sows of similar size require observation of the insertion depth of the insemination tube into the sow's vagina on the left side each time, ensuring a consistent insertion depth, which is cumbersome. Therefore, a hygienic insemination tube for pigs is needed to address this issue. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hygienic insemination tube for pigs, which aims to improve the problem that the existing technology requires adjustments each time to ensure that the insertion depth into the sow's vagina is close, which is quite troublesome.
