Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a raised-bed farrowing pig pen that is hung over a sewage ditch in a pigsty and used during farrowing and the subsequent lactation period for newborn pigs.

Traditionally, in order to save labor in cleaning pigpens and to maintain a clean environment inside the pigpen, so-called raised-bed type systems have been used, in which a screen floor is stretched over a concrete waste groove, and excrement and urine fall between the screens. It has been put into practical use. However, in winter or in cold regions, this raised-bed type can allow cold air to enter between the cages and cool the sow's abdomen, resulting in a decrease in milk production or the newborn piglets dying from cold immediately after birth. It was hot. In particular, it is preferable to raise piglets after birth at a temperature of 25 to 35°, but it is extremely difficult to maintain the temperature within this range in raised-bed pigs because of the intense air circulation. In addition, because the spacing between the cages was adjusted according to the sow's leg anchorage, there were defects such as newborn piglets' feet falling off between the cages, resulting in damage to the newborn piglets' feet.

The present invention was developed in view of the above, and has an extremely simple structure that keeps newborn piglets at a necessary and comfortable temperature, prevents cold death, and prevents newborn piglets' feet from falling out from between the cages. The purpose of the present invention is to provide a farrowing pen that can prevent the above.

One embodiment of the present invention will be explained with reference to the drawings.
This is a longitudinal sow bed made of a cocrete layer laid on the upper surface of an inverted trapezoidal iron frame, and a plurality of slits 2 for excrement and urine discharge are formed at both ends of the short side. Reference numeral 3 indicates a perforated bed placed closely on both sides of the sow bed 1 in the longitudinal direction. Many are formed. 5 shows a non-porous newborn pig bed formed on one part of the perforated bed 3, and a heater with a nichrome wire attached to the top surface of a heat insulating material such as styrofoam is permanently installed on the lower surface of the newborn pig bed 5. There is. The sow bed 1 and the clear hole bed 3 are placed on the upper surface of the girder 7 extending between the four pillars 6 and fixed with bolts and nuts to form the floor of the farrowing pig pen. Reference numeral 8 denotes a heater with a heat insulating material attached to the lower surface, which is inserted into the inverted trapezoidal frame of the sow bedding 1 and the hole-opening bed 3, and is inserted into the bottom plate 9 formed on the bottom of the sow's bedding 1 and the hole-opening bed 3. The heater 8 was detachably attached by passing it over. In addition, the slit 2 corresponding to the position of the sow's butt on the sow bed 1
Attach it to the bottom of the The heater 8 is provided with an appropriate number of micropores 13 for urine drainage. By installing this heater 8 below the floor, the slit 2 of the sow bed 1 and the small hole 4 of the perforated bed 3 are closed, preventing drafts from entering from these parts, and by installing the heater 8, Prevents temperature drop inside the pig stall. Furthermore, since the slit 2 and the small hole 4 are closed, the newborn piglet does not fall off its feet into the slit and the small hole 4. In the illustrated example, since the floor is long in the longitudinal direction, the heater 8 is halved and inserted from both sides of the floor. Reference numeral 10 denotes a partition shelf surrounding the floor supported by pillars 11 projecting perpendicularly from the four corners of the floor. This prevents the sow from entering the hole bed 3 and the newborn pig bed 5 and from turning the head and rump of the sow upside down, thereby preventing the newborn piglet from being crushed to death by the mother sow. It is prevented. In addition, the lower end of the partition shelf 12 is formed in a partially arched shape, so that there is a distance from the floor to a height that allows the piglets to pass through, so that the piglets can move in the direction of the sow's udder. , the piglets can freely move between the three holes on both sides, and the piglets can freely drink the mother's milk.

In the figure, 14 is a door, and 15 is a knob for entering and exiting the heater 8. Further, although the drawing shows an example in which a single farrowing stall is used, the newborn pig beds 5 may be placed adjacent to each other so that the newborn pig beds 5 are mutually warmed to be efficiently installed.

However, according to the present invention, since the heater is removably installed in the high-floor delivery room with a lot of drafts,
By preventing drafts, the inside of the farrowing pen can be maintained in an optimal environment for raising newborn piglets, and the newborn piglets will not die of cold and the body temperature of the newborn piglets will not drop. , the piglet can drink the precious colostrum of the mother pig, which greatly benefits the later growth of the piglet. In addition, the heater can be easily attached only for the necessary 2 to 5 days after the sow has given birth, so once the required period has passed, the heater can be removed and attached when giving birth in another farrowing stall. This is more economical than permanently installing heaters in all delivery rooms. In addition, by installing a heater on the floor, the room temperature inside the delivery room will not only increase, but the floor will be dry and the inside of the delivery room will be clean.
It has effects such as being able to maintain the health of newborn piglets. Further, even if a large number of openings for excrement discharge are formed on the floor surface, the openings are closed by installing the plate-shaped heater, and the feet of the newborn piglet will not fall off and be damaged.

As described above, according to the present invention, it is possible to maintain a farrowing pen at a comfortable temperature and environment at a very low cost and easily, and to make the floor surface flat, so that newborn piglets can be raised in a good environment. Therefore, cold death and leg damage of newborn piglets can be eliminated, and the newborn piglets can develop well.
