Abstract

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.

Description

A DEVICE FDR ARTIFICIAL INSEMINATION OF ANIMAL HUSBANDRY. BACKGROUND OF THE INVENTION

The invention relates to a device for use in the artificial insemination of a domestic animal, especially a sow.

When carrying out artificial insemination, the sperm container has hitherto been held in the hand. This has been very time-consuming when several sows have required to be inseminated, and with the known methods there have also been problems with getting the sow to stand still so that the insemination can be carried out in an efficient manner.

EXPLANATION OF THE INVENTION

The new and special aspect of the invention is that the device comprises a holder designed for the sperm container, said holder being secured to a support element arranged to rest on or be secured to the sow.

With the device according to the invention, the sperm container can be held by the support element in such a manner that the sperm container can be held without manual assistance. With several devices according to the invention, it is thus possible to inseminate several sows at the same time.

As disclosed in claim 2, it is preferred that the support element comprises a hoop which, during the insemination, can rest on the sow's back and at the same time lie up against the sow's sides. With these arrangements, it is achieved that the sow is stimulated in the same way as when a boar influences the sow with its abdomen and its front legs. During insemination with the device, the sow will react with a natural reflex and stand with curved back, and it will also stand calmly during the insemination.

With the device as disclosed in claim 3, it is achieved that the sperm can flow into the sow solely under the influence of gravitation.

As disclosed in claim 4, it is preferred that the holder supports the sperm container in a loose manner, so that the container is free to move during the insemination.

THE DRAWING

A preferred embodiment of the device according to the invention will now be described in more detail with reference to the drawing, where

fig. 1 shows the device according to the invention seen from the side, and

fig. 2 shows the device seen in perspective during its use in the artificial insemination.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With a preferred embodiment of the invention, the device is configured as a hoop element 1 and a holder 2 for sperm tubes.

The hoop element 1 consists of long, flat pieces of stainless steel, and has a basic part 3 connecting two hoops 4 and 5 with the holder 2.

The hoops 4 and 5 are flexible so that they can clamp down around the body of a sow. The holder 2 is configured at an angle in relation to the basic part 3 and is positioned so high that the lower part of the holder 2 is situated above a sow's vaginal orifice during insemination. The holder 2 has a hexagonal cross-section and is provided with a longitudinal slot. The sperm tube lies loosely in the holder 2, so that to a certain degree it can follow the movements of the sow 7.

During artificial insemination, the basic part 3 is positioned on the sow as shown in fig. 2. The hoop 5 will thus stimulate the sow in the same way as the front legs of a boar. Similarly, the basic part 3 will influence the sow like the boar's abdomen. The sow will thus stand quite calmly with curved back until the sperm has run out of the sperm tube 6.

It is preferred to provide the device with a handle 8 for use in the handling of the device.

With the help of three devices according to the invention, a pig farmer can inseminate 10-15 sows in approximately 20 minutes.

Claims

C I M S

1. Device for use in the artificial insemination of a domestic animal, particularly a sow, c h a r a c t e r i z e d in that the device comprises a holder intended for the sperm container, said holder being secured to a support element arranged to rest on or be fastened to the sow.

2. Device according to claim 1, c h a r a c t e r i z e d in that the support element comprises a hoop which, during the insemination, can rest on the sow's back and at the same time lie up against the sow's sides.

3. Device according to claim 1 or 2, c h a r a c t e r i z e d in that the holder is arranged to hold the sperm container at an inclined angle and above the level of the sow's vaginal orifice.

4. Device according to any of the foregoing claims, c h a r a c t e r i z e d in that the holder supports the sperm container in a. loose manner, so that the container is free to move during the insemination.
