Description

[Detailed description of the invention] The gist of the present invention is to use it by attaching it to a pig farrowing frame.

Alternatively, the equipment used as part of the farrowing cage is equipped with a blower which blows air into the lower part of the udder when the pig is standing in the farrowing cage. This equipment is equipped with a device that detects when a pig is standing so that the blower is activated only when the pig is standing to blow in lice. This prevents the piglet from going under the udder of the standing sow, which could be dangerous.

That is, when pigs are farrowing, they are usually farrowed within a framework that restricts the sow's movement. This frame allows the sow to stand or lie down, and newly born piglets can enter and exit from between the frame and the horizontal bar at the bottom of the frame.

One of the main reasons why many newly born piglets die is
This is because newborn piglets are crushed to death because they are sows. Piglets tend to gather under the sow's udder when she stands up. And when the sow lies on the floor, some of the piglets are unable to escape and are crushed.

Accordingly, one object of the present invention is to provide a means of reducing crush death of newly born piglets.

It is a further object of the present invention to prevent crushing of new piglets by attachment to conventional farrowing crates.

Another object of the present invention is to prevent newly born piglets from being crushed to death by being placed in a farrowing frame.

According to the invention, this Fli appliance used as a farrowing frame for pigs or as an element of a farrowing frame is provided with a device for transmitting K between the udder of a sow standing in the frame and the floor. Stand inside. The sow is equipped with a device for detecting a sow, and further includes a device for activating a feeding device in response to the detection device. Thus, air is only blown into the frame when it detects that a sow is standing.

The present invention reduces by 2 the number of piglets that are crushed to death because they cannot escape from under the sow when the sow is standing in the frame. When this device detects that a sow is standing in the frame, a louse is loosely placed under the sow's udder, and the piglets, which tend to gather under the udder, dislike the louse and run away from the frame. . When a sow tries to lie down, very few piglets are there, and even if there are a few piglets, the sow will chase them away and lie down, so crushing the piglets to death is completely prevented. As soon as the sow lies down, the detector switches off the blower and the piglet reenters the frame.

Hereinafter, a persimmon example of the present invention will be explained in detail with reference to the drawings.

As shown in FIG. 2, conventional farrowing cages for pigs consist of a structure 1 of a size that allows a sow to stand or lie down in the farrowing cage, but does not allow her to change direction. This structure is made of a material with sufficient strength, and metal tubes are often used. In use, there is a space between the lower horizontal bar 3 and the floor, and it is placed back to back to the frame. The opening is structured so that the piglet can freely enter and exit through a hole (not shown).

The device of the present invention shown in FIG. 1 is attached to a delivery frame 1 as shown in FIG. The equipment includes a vertical conduit 4, an electrically actuated feeder 1 mounted on the top of the vertical conduit 5, and a machine 5. The lower end of the vertical conduit 4 connects to the central part of a substantially horizontal tube 6 which is closed at both ends.

The tube 6 is provided with a plurality of holes 8, for example thirteen holes. This hole 8 is drilled with a certain spacing in the horizontal direction of the tube 6, and the hole 8 is opened at a certain distance in the horizontal direction of the pipe 6. ! ! Stay in position 1- with the 1st fly from 5 pointing slightly downward. For example, adjacent holes deflect 14 with angular deviations of 15 DEG and 30 DEG relative to the horizontal direction l-1.

Further, an electronic stand 9 and an optical detector 10 attached to the conduit 4 with height-adjustable sliding fittings are connected to a power source through a conductive wire 11. This detector may be conventional. For example, place m1 in the frame opposite to detector 10! ! .

It may be an infrared transmitter that cooperates with a detachable receiver 412 (see FIG. 2). The detector 10 is connected to the operating part of the blower 5 through a conductor 13. Photocells can also be used as an alternative.

This device can be easily attached to the frame 1 as shown in FIG. Therefore, the tube 6 can be connected to the lower horizontal bar 13 back to back with the support 14. On the other hand, the conduit 4 is attached to an adjustable channel 16 which can be attached to the upper crossbar 17 of the frame. The device is horizontally adjustable OT to set it in the appropriate position for delivery to the sow's udder F51L'. This simple installation allows the device to be adapted to any size and type of farrowing cage.

In use, the optical detector 10 and reflector 12 are mounted in a position such that they can detect the rising of the sow within the frame. The electrical signal generated by the detector is sent to the bottom of the sow via a transmission Kfi switch. The curtain of air thus introduced into the sow θ) should be constructed in such a way that when the sow is standing, the piglets will not be in the area under and behind the udder. This device is installed back-to-back with the direction of the piglet hole, so the lice are blown from the direction of the hole. The piglet can therefore move away from the air curtain and into the extraction hole. When the sow lies down in the frame, the position of the sow's body is below the level of the detector 10, so the detector immediately switches off the rocker 5 and stops the feed to the bottom floor. There, the piglets can come back from the hole.

The device can be made of any suitable material, such as PvC tubing. Dimensions can also be varied as required.

The transmission line 11i1!5 may also be of any suitable form.

And it is compatible with the voltage of any country.

Figures 3 and 4 show the configuration of this equipment as a delivery frame.

FIG.

The lowermost horizontal bar 21 of the farrowing frame 20 is tubular and has a plurality of holes 22 on the inner surface of the frame.The holes are the same as those shown in FIGS. 1 and 2.

The blower 23 is mounted on the frame 20.

One or more substantially vertical tubes 240 form part of the frame, which extends from the blower 23 to the horizontal tube rod 21.
The detector 26, which is identical to the detector 'a1o of FIGS. attached to the top. If desired, the tube 24 can be moved laterally along the horizontal bars of the frame. At the rear end of the frame 2o,
There is a low extended side wall made of corrugated pleats 31. These corrugated folds receive a rear restriction device f of the sow, for example a removable rear restriction frame.

The operation of this device is the same as described with respect to Figures 1 and 2, and the detector 26 detects the presence of a standing pig. Detects and sends ltk below the udder, and when the pig lies down, the detector sends 1t
Let me correct the k-stop.

Alternatively, a compressed air supply source such as a compressor, compressed air cylinder or cylinder may be used in place of the blower 5 of FIGS. 1 and 2 or the blower 11 of FIG. 3. In this case, air is passed directly from the cylinder through suitable valves 1 to the tube 6 or the crossbar 21, or to other convenient locations, such as for example the conduit 4 or the tube 24. This air should be controlled according to the detector as described above.

As detailed above, the present invention provides a method and device for preventing crushing of piglets, which is extremely beneficial to livestock farmers.
