Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor structure for farrowing pig pens that allows sows to easily suckle.

After parturition, the mother is usually kept in a farrowing pen with her piglets. As shown in FIG. 1, a farrowing pen is generally surrounded by a fence or panel 1, and near the center thereof is provided a farrowing fence 2 whose lower part is wide enough to allow the sow to lie down. 3 is a rear door for the sow, 4 is a rear door that serves as the entrance and exit for the sow, and 5 is a butt stop for determining the position of the sow.

The mother pig before farrowing is housed in the farrowing pen, and the piglet after farrowing is kept in the pig stall floor 6 in the pen 1, and the sow lies down in the farrowing pen 2 during suckling and gives milk to the piglets. .
This can prevent accidents such as crush death and leg cramps that tend to occur in infants after birth.

There are various types of farrowing pig pens, such as those in which the feed tank 3 opens and closes with a screw and also serves as a door 4, those with concrete floors, those with a slatted floor, or those with a net. Generally, the floor is the birthing fence 2
It has a planar structure including the inside.

However, when the sow lies down to nurse, the lower row of udders comes into contact with the stall floor, making it difficult for the piglets to suckle milk from the udders. A mother pig's udders are arranged in 14 to 18 rows, arranged side by side, but each piglet has a habit of occupying a specific udder, so there are 9
~When 12 piglets give birth, all of the piglets cannot occupy their own breasts in udders 7 to 9 in one row, and those who cannot occupy the udders suffer from stunted growth. There was a problem.

In some farrowing pens, the floor inside the farrowing fence 2 is one step higher than the floor in other areas, but since the floor inside the farrowing fence is flat, the sow's floor is lower when she lies down. There is no difference in that the side breast rows will touch the floor and the piglets will not be able to suckle properly.

The present invention has a medium-high floor in the farrowing enclosure, so that when the sow lies down, her abdomen is slightly upward, and the lower udder is also off the floor, so that she can suckle from all udders. The purpose of this invention is to provide a farrowing pig pen that solves the above problems.

The present invention will be specifically described below with reference to the drawings.

FIG. 2 shows an embodiment of the farrowing pen according to the present invention, taken along the line A-A' in FIG. In particular, the pig stall floor 6 is made of net made of expanded metal that has broken down vinyl resin, etc.
However, in the present invention, a portion 9 inside the farrowing fence 2 bulges upward in a semicylindrical shape.

If the sow lies down on the floor that bulges upward in this way, as shown in Figure 4, the width of the farrowing fence 2 is only wide enough for the sow to lie down, and the sow will lie on one side of the floor center line. The sow's center of gravity is placed on it, the udder is slightly upward, and the lower row of udders is also off the floor, allowing the piglets to easily nurse from the lower udder.

The above effect is not limited to the shape of the floor as shown in FIG. It is sufficient to have a reversely sloped floor on both sides.

The floor 9 is not limited to a net, and the above effect can be achieved even with a concrete floor as long as the central portion is bulged.

However, if this is made of expanded metal as described above, the sow's tread surface will have a gentle slope as a whole, but the net surface will have unevenness so it will not slip and be safe. The net shape allows dirt to be removed easily and is hygienic, and the floor surface can be formed extremely easily since it is only necessary to lay a pre-expanded net. In this case, forming and laying the floor will be easier if the pig stall floor is divided into appropriate parts instead of being formed in one piece. Fig. 6 shows an example in which the floor is divided into six parts, and Fig. 7 shows an example in which the floor is divided into four parts, with the rear part of the butt stop being flat. FIG. 8 shows an example in which the bulge has an oval shape as shown in the cross section shown in FIG. 8b.

In addition, if the above-mentioned bulge is connected to the horizontal part at the side of the bulge as in the above embodiment, there will be no step in this part and there will be no risk of the pigs damaging their legs, making it safer. becomes more sexual.

As described above, the present invention has a simple configuration in which the floor of the pig stall between the farrowing fences is bulged upward, but all the udders of the lying sow are exposed and all the newborn piglets are sufficiently suckled. It has the remarkable effect of being able to Furthermore, if the pigpen floor is made of net, the problem of sows slipping on the sloping floor due to the bulging can be solved at the same time, and it also has the effect of making the construction of the pigpen easier. It is something.
