A device for use in the artificial insemination of sows is built up of a basic part (3) which has two hoops (4, 5) for securing the device around the back and sides of a sow (7), and which at its one end is provided with a holder for a sperm tube (6). During the use of the device according to the invention, the hoop (5) and the basic part (3) will stimulate the sow (7) in the same manner as a boar, and therefore the sow (7) will stand still with curved back during the process of insemination. Manual work is thus to a great extent eliminated by the use of the device. |
