Description

Sow Fertilization Aid

technical field

The utility model relates to the field of artificial insemination of sows, in particular to an auxiliary device for insemination of sows.

Background technique

With the development of biotechnology, artificial insemination and embryo transfer technology have been widely used in animal husbandry. Among them, intrauterine insemination of pigs is an insemination technology that transfers sperm into the uterus through the vagina. Pig intrauterine insemination technology has almost all the advantages of traditional artificial insemination technology (at the cervix), in addition, it greatly reduces the amount of semen and sperm concentration per insemination, thereby reducing the cost of introducing and raising boars.

Both natural mating of pigs and traditional artificial insemination methods have huge waste of sperm resources. Each semen requires 3 to 4 billion sperm. Intrauterine artificial insemination technology requires that the total sperm count per semen is not less than 1 billion. In addition, intrauterine insemination can effectively prevent the phenomenon of semen backflow, which opens up a new way to give full play to the genetic potential of super breeding pigs. It is of great significance especially for the use of special semen that is not easy to obtain, such as frozen semen or sex-controlled semen.

However, it is difficult to complete breeding due to the violent temperament of sows in estrus, and the sows at this time are very easy to hurt people. Therefore, it is necessary to design an auxiliary device for sows insemination.
