Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a device for assisting the mating of male and female pigs of different body sizes.

(Prior art) When inseminating pigs, mating does not go as planned if the male and female pigs have different body sizes, and if the female is smaller and the male is larger, the younger female gets tired and has trouble moving. This often results in inability or insufficient fertilization, and on the other hand, when the female is large and the male is small, it is almost impossible to fertilize because they cannot reach each other. Workers help there, but the work is very arduous, and if there is a significant difference in height between the male and female, it is almost impossible to adjust.

(Problems to be solved by the present invention) The present invention has been developed in view of the conventional situation, and is designed to enable both the male and female to mating smoothly in a stable and comfortable posture in any of the above cases. The aim is to provide an auxiliary device.

[Structure of the idea]

(Embodiment) To explain the embodiments in the drawings below, in Figs. On the bottom frame 2, an elevator 7 is installed on the rear bottom surface with approximately the same width as the frontage of the bottom frame 2, and a widening auxiliary plate 9 is installed at the left and right ends via hinges 8. A freely attached floor board 6 is provided so as to be freely accessible. That is, when stored, the width-expanding auxiliary plates 9 on both sides are folded inward. In addition, a support stand 10 is installed at the rear upper part between the two side frames 4, 4, so that the pig insemination aid of the present invention is constructed.

The middle floor board 6 is equipped with wheel racks 11 on the left and right sides of the front end in order to smoothly move in and out along the bottom frame 2, but it goes without saying that a simple sliding type may be used.

In the drawings, reference numeral 12 indicates a feeding device attached to the front frame 3, and reference numeral 13 indicates a body length adjustment plate provided between the left and right side frames 4, 4 so as to be able to be moved back and forth.

(Function) To use the device of this invention with the above configuration, remove the rear frame 5 in the state shown in Figures 2 and 3, and if the male pig is large and the female pig is small, remove the floor plate 6. The sow is guided into the frame 1 in that state. At this time, if the front feeder 12 is filled with bait, the bait will be attracted and enter the frame 1 with less resistance, so the rear frame 5 will be closed. Then, the body length adjusting plate 13 is moved back and forth according to the body length of the sow so that the buttocks of the sow face the upper part of the rear frame 5. Then, the elevator 7 is further operated to raise the rear part of the floorboard 6 to appropriately lift up the buttock of the sow. Therefore, when a large male pig outside the frame is guided behind the frame 1, the male pig is placed on the support stand 10.
The forelimbs are placed on the body and the chest is placed on the body. In this comfortable position, you can easily fit the lifted sow (Figure 6).

Next, if the male pig is small and the sow is large, from the state shown in Figs. 2 and 3, as shown in Figs. A widening auxiliary plate 9 provided at the end via a hinge 8 is opened to both sides. Then, remove the rear frame 5 and place the sow in the frame 1.
Guide inside. That is, large sows are placed directly onto the bottom frame 2. At this time, the function of the front feeder is the same as before. Then, close the rear frame 5 (in this case, since the male is smaller, it is not necessary to close the rear frame 5), and place the small male stud on the floorboard 6.
lead upwards. Then, widening auxiliary boards 8 are installed on both sides of the floor board 6.
Since the boar is extended, the boar moves from side to side without any anxiety, and as shown in Fig. 5, hangs his forelimbs on the support stand 10 and attaches it to the bottom frame 2, that is, the large sow in the low position. can be done. In this case, when the elevator 7 is raised, the boar is further pushed up and its posture is stabilized (also shown in FIG. 5).

[Effect of idea]

This idea is as described above, and if there is a difference in body height between male and female pigs, the floorboard 6 (including the widening auxiliary board 8)
By moving in and out, it is possible to adapt to either large or small animals, significantly reducing physical fatigue for both males and females, and therefore lengthening the mating time, improving the conception rate and the number of offspring. can bring about an increase in

It is also very advantageous for pig farmers because there is almost no auxiliary work required for mating.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention. Figure 1 is a perspective view (when the floorboards are pulled out), Figure 2 is a side view (when the floorboards are stored), Figure 3 is a rear view of the same, and Figure 4 is the floorboards pulled out.
