Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a non-nursing farrowing device for farmed pigs, which allows pregnant sows to farrow without the need for assistance from a nurse. This invention relates to a non-nursing farrowing device for pigs that allows piglets to be separated from their mother pigs and housed in a storage box.

[Prior Art] In general, in pig farming, sows nearing the time of giving birth are housed in a farrowing fence in which the sow's posture cannot be changed in the front-back direction, and the sow is allowed to give birth there.

In this case, nurses have traditionally been required to assist the piglets in order to prevent them from being crushed to death, suffocating to death, or freezing to death in the winter. Since most of the nursing care is performed at night, the nursing care can sometimes involve staying up all night, making it extremely troublesome work for nurses.

In order to relieve nurses from such troublesome nursing care, the present applicant has previously proposed a non-nursing delivery device (Utility Application No. 59-179537). In this non-nursing farrowing device, the rear part of the fence is lowered one step to form a recess, a box for receiving piglets is placed in this recess, and the piglets are delivered into this box. This allows the sow and piglets to be separated quickly.
We try to protect piglets from the crushing and suffocation mentioned above.

[Problems to be solved by the invention] By the way, in the above-mentioned non-nursing farrowing device, the sow is introduced into the fence from the recess, but since the recess is lower, the sow cannot rise up. difficult,
In particular, pregnant sows move slowly, making it extremely complicated to put them inside the fence. There was also the problem that if the baby got caught on the step and fell, it could cause injury or miscarriage.

The present invention was devised in view of the above-mentioned problems, and its purpose is to allow sows to be easily placed inside the enclosure.

[Means for Solving the Problems] The means of the present invention for solving such problems includes an outer frame installed on the floor of the pigsty, and a fence floor on which pregnant sows are placed. A non-nursing farrowing device for pigs, comprising a farrowing fence that regulates the change of the sow's posture, and housing piglets delivered by the sow on the fence floor in a holding box arranged at the rear of the farrowing fence. , a lowered position where the floor of the farrowing fence is brought into contact with the floor of the pigsty, and a step is formed between the floor of the pigsty and the rear end of the fence so that the rear end of the fence faces the entrance of the storage box. The farrowing fence is supported relative to the outer frame so as to be movable up and down in two positions, including a raised position, and the outer frame is provided with a lifting device for moving the farrowing fence up and down, and the outer frame is supported in the raised position of the farrowing fence. A supporting member is provided to support the fence floor of the raised farrowing fence, which is removably constructed on the
Furthermore, a fall prevention plate is provided on the side of the fence floor of the farrowing fence to prevent piglets from falling when they crawl next to the mother sow.

[Example] Hereinafter, a non-nursing pig farrowing device according to an example of the present invention will be described in detail based on the accompanying drawings.

As shown in FIGS. 1 to 3, the non-nursing farrowing device according to the embodiment has a concrete pigsty floor surface 1.
The farrowing fence 2 has a gate-shaped outer frame 3 that is installed on the fence floor 8, and a farrowing fence 2 that has a fence floor 8 on which a pregnant sow is placed and regulates changes in the posture of the sow on the fence floor 8. The piglets delivered by the upper sow are housed in a storage box 4 arranged at the rear of the farrowing fence 2.

As shown in FIG. 4, the housing box 4 is provided with a lid 21 that can be opened and closed at the top, and an open entrance 19 through which piglets can pass through the side facing the farrowing fence 2. An electric heater 20 for keeping the piglet warm is attached to the inside of the lid 21, and an electric heating mat 18 for keeping the piglet warm is attached to the bottom.

The outer frame 3 has three gate-shaped pipes arranged side by side, the legs of which are buried in the floor of the pigsty, and the upper ends of these arranged gate-shaped pipes are connected by an outer frame beam 16 made of pipes.

Further, the farrowing fence 2 is provided within the outer frame 3 and includes a pair of gate-shaped pipes having a shorter length than the gate-shaped pipes of the outer frame 3, and each of the pair of gate-shaped pipes is connected to the outer frame. 3, and are connected at the lower end by a floor frame 9, and at the upper end by a fence beam 11 made of pipes. In addition, the gate-shaped pipe of the farrowing fence 2 has a pair of horizontal fences 1 facing each other on the inside thereof and running along the sides of the sow.
0 are attached to the pipe so that their mutual spacing can be adjusted.

Furthermore, a fence floor 8 is laid on the floor frame 9. A fall prevention plate 12 is provided on the side of the fence floor 8 to prevent piglets from falling when they crawl next to the mother pig.

Further, above the rear end of the fence floor 8 of the farrowing fence 2, there is provided a butt stopper pipe 13 which is detachably attached to the horizontal fence 10 and which holds down the sow's butt. Furthermore, above the rear end of the fence floor 8 of the farrowing fence 2, there is a manure scattering prevention plate which is detachably attached to the horizontal fence 10 and comes into contact with the manure excreted by the sow standing on the fence floor 8. 14 are provided.

Further, the farrowing fence 2 has a lowered position where the fence floor 8 of the farrowing fence 2 is grounded to the pigsty floor surface 1, and a step is formed between the pigsty floor surface 1 and the rear end of the fence floor 8. It is supported so as to be movable up and down relative to the outer frame 3 so that the rear end can be positioned at two raised positions where the rear end can face the entrance 19 of the storage box 4. This support means is constructed by attaching a guide pipe 6, which is vertically slidably inserted through the gate-shaped pipe of the outer frame 3, to the gate-shaped pipe of the farrowing fence 2.

Furthermore, a lifting device 17 for moving the farrowing fence 2 up and down is suspended from the outer frame beam 16 of the outer frame 3. This lifting and lowering device 17 is composed of a so-called chain block that winds and unwinds a chain, and the end of the chain that is wound and unwound is connected to the fence beam 1 of the farrowing fence 2.
It is attached to 1.

This birthing device also includes support pipes 7 which serve as support members that are removably installed on each gate-shaped pipe of the outer frame 3 in the raised position of the birthing fence 2 and support the floor frame 9 of the raised birthing fence 2. We are prepared.

Incidentally, reference numeral 5 is a feeding port for feeding the mother pig.

Therefore, the non-nursing delivery device according to this embodiment operates as follows.

First, when placing a sow that is about to give birth into the farrowing fence 2, as shown in FIG. Enter from the rear of farrowing fence 2.
In this case, the fence floor 8 of the farrowing fence 2 is approximately flush with the pigpen floor 1, so the sow can walk and rest on the fence floor 8, even if her movements are slow due to pregnancy. This makes it extremely easy to enter the fence, and prevents the user from getting caught and falling.

Next, the stopper pipe 13 and the excrement scattering prevention plate 14
and drive the lifting device 17 to set the farrowing fence 2 to the raised position as shown in FIG.
support. In this case, the floor fence 8 is supported by the support pipe 7 via the floor frame 9, so that wobbling is prevented and the heavy sow is reliably supported.

In this state, the fence floor 8 of the farrowing fence 2 rises, so that a step is formed between the pigsty floor surface 1 and the rear end of the fence floor 8.

Thereafter, when the storage box 4 is brought to the rear of the farrowing fence 2, the rear end of the fence floor 8 faces the entrance 19 of the storage box 4. In this state, when the sow farrows, the piglet is dropped onto the rear end of the fence floor 8, and when the piglet moves and comes off the rear end, it descends into the storage box 4 through the entrance 19. To go. This results in
The sow and piglets are separated. This prevents the farrowed piglets from being crushed to death or suffocated by the huge mother sow. Further, since the piglets are separated from the rear end of the fence floor 8 by descending into the housing box 4, the nurse does not have to assist each piglet every time, which reduces troublesome work.

In this case, even if a piglet that has once entered the storage box 4 tries to climb up to the fence floor 8 in search of milk from the mother pig, there will be a gap between the pigpen floor surface 1 and the rear end of the fence floor 8. Since the step is formed, the fence floor 8 is higher than the floor of the storage box 4, thereby preventing the fence from climbing up.

When placed in the housing box 4, the housing box 4 is heated by the heat insulating mat 18 and the heater 20, so it is warm, and this prevents the sow from dying due to the cold even if it is separated from the mother pig. .

Furthermore, when a piglet delivered to the rear end of the fence floor 8 cannot descend into the holding box 4, the piglet generally crawls to the side of the sow in search of milk from the sow.
Since the fence floor 8 is provided with a fall prevention plate 12, even if the fence floor 8 is in the raised position and is high, the piglet is prevented from falling.

Also, when the sow stands up and excretes manure,
Since the excrement comes into contact with the excrement scattering prevention plate 14, the excrement falls downward without scattering backward. Therefore, the situation where the storage box 4 gets dirty or the inside of the storage box 4 becomes dirty due to entering deep through the entrance 19 is suppressed.

[Effects of the invention] As explained above, according to the non-nursing farrowing device for pig farming of the present invention, when the farrowing fence is set to the lowered position, the fence floor of the farrowing fence becomes substantially flush with the floor of the pigsty; Since there is no step like in the previous example, the sow can walk and stand on the fence floor.
This improves work efficiency by allowing the sow to enter the farrowing fence easily even when her movements are slow due to pregnancy.In addition, since there are no steps, it is possible to prevent the sow from getting caught and falling. This can prevent pigs from getting injured or having miscarriages.

In addition, at the raised position of the farrowing fence, a step is formed between the floor of the pigsty and the rear end of the fence.
Piglets that are farrowed at the rear end of the fence floor are able to descend into the housing box by their own movement, and once piglets have entered the housing box, it is difficult for them to climb up onto the fence floor. Therefore, it is possible to reliably separate the mother pig and piglets.

Furthermore, piglets that were farrowed at the rear end of the fence floor were
Even if the piglets are unable to descend into the storage box and end up crawling to the side of the mother pig, there is a fall prevention board on the fence floor, so the piglet will not fall and that is all there is to it. , it is possible to reduce the mortality of piglets.
