Abstract

The invention discloses a vas deferens for artificial insemination of pigs, comprising a tube body, wherein the tube body is provided with a head part and a tube body, and the top end of the head partis provided with a sperm infusion port communicated with the tube body, and is characterized in that the head part is wrapped with a cellophane film, a lubricating liquid layer is arranged between the cellophane film and the outer surface of the head part, and the thickness of the cellophane film is 0.1 mm- 0.3 mm, and the tube body is provided with a valve structure, wherein the valve structureis composed of two semicircular membranes with the same size, and the semicircular membrane is provided with an arc edge fixedly connected with the inner wall of the tube body. By providing a cellophane film at the head of the vas deferens and then providing a lubricant layer between the cellophane film and the outer surface of the head, the vas deferens is provided with a lubricant. The problem that the pig is easy to be infected due to the operation of the vas deferens in the prior art is avoided. At the same time, the valve structure prevents sperm return and improves the conception rate ofsows. The vas deferens can be used for artificial insemination of pigs.

Description

technical field [0001] The invention relates to the technical field of livestock breeding devices, in particular to a vas deferens used for artificial insemination of pigs. Background technique [0002] The vas deferens are often used in artificial insemination of pigs. During the use of the existing vas deferens, lubricating fluid needs to be manually added. However, since many people work together during artificial insemination, they will share a Bottles of lubricating fluid, which increases the possibility of lubricating fluid being contaminated, can also lead to infection of pigs due to contaminated lubricating fluid. When using the existing vas deferens to artificially inseminate pigs, it will also reduce the chances of sows getting pregnant due to sperm backflow. [0003] Therefore, there are various defects in the existing vas deferens, which urgently need to be solved. Contents of the invention [0004] Aiming at the defects of the prior art, the present inventio...
