Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pig farm feeder provided in a pig pen.

[0002]

2. Description of the Related Art Conventionally, as a pig feeder, as shown in FIGS. 5 and 6, a feeding tank 43 having a water supply pipe 42 is formed at the bottom of a box 41, and a feed is provided above the feeding tank 43. Is provided with a feed storage room 44. A feed port 45 for discharging the feed and an adjusting plate 46 for adjusting the opening area of the feed port 45 are provided at the bottom of the feed storage chamber 44. At the lower part of the feeding port 45, the feed storage room 44
An inclined plate 47 for feeding the feed into the feeding tank 43 is formed. Further, a handle 49 is connected to the adjusting plate 46 via a shaft 48 that can move back and forth.

[0003]

By the way, conventionally, it is considered that it is easier for pigs to eat the feed when it is wet with water, and in the above-mentioned conventional pig feeder, it is discharged from the feed storage chamber through the feeding port. The feed was dropped into the water tank and put into the water that was stored.

However, the present inventor has found that when feed is supplied by a conventional pig feeder, there is a large amount of feed that remains uneaten by pigs (hereinafter referred to as waste food), which is extremely uneconomical. . It is considered that this is because the feed wet with water clumps like a dango, and the pig's palatability becomes worse with respect to such a dango-like feed.

Further, it is difficult to control the feed amount of feed, which is a problem particularly in the case of feed having good fluidity (pellet-processed feed). That is, if the adjustment plate is opened too much, too much feed will come out and the water tank will fill up.On the contrary, if the adjustment plate is closed too much, the feed will become difficult to feed, and the feed will be gelatinized by the saliva of pigs, etc. It was clogged and there was no feed at all. Therefore, it was troublesome that the feed feeder had to be frequently managed.

In addition, when pigs eat the feed, they often eat with the front legs inserted into the feed tank, and the feces and litter attached to the front legs enter the water receiving tank and the water receiving tank becomes unsanitary. It was.

The present invention solves the above-mentioned problems, prevents the fed feed from being wasted, and accurately adjusts the feed amount of feed, thereby suppressing the clogging of the outlet due to the lavering of feed. It is also an object of the present invention to provide a feeder for pig farming, which is capable of maintaining a hygienic condition by using a feeding tank as a water receiving tank.

[0008]

The present invention has been made to achieve the above object, and a pig feeder according to the present invention comprises a water receiving tank and a water supply pipe for supplying water to the water receiving tank. , A feed storage room in which a feed opening for discharging feed whose horizontal length becomes shorter as it goes upward is formed in the lower front part, an adjusting plate for opening and closing the feed opening, and an upper part of the water receiving tank. It is characterized in that it is provided with a feed receiving stand for holding the feed provided from the feed storage room without dropping it into the water receiving tank.

The feed cradle may be any as long as it can hold the feed fed from the feed storage chamber without dropping it into the water receiving tank. For example, the feed cradle may be horizontally wide or the water receiving tank side may be obliquely upward. It may be formed with an inclination, or the tip may be raised upward to form a convex edge.

Further, the feed cradle is preferably provided with at least one step (thus, at least two surfaces, an upper surface and a lower surface, are formed). That is, when saliva of pigs or the front legs are placed on the feed pedestal and water attached to the front legs supplies water to the feed pedestal,
Water spreads over the surface of the feed cradle, and the feed absorbs this water to form a paste. Then, the paste-like feed solidified from the lower part to the upper part and blocked the feed supply port of the feed storage room. Therefore, if a step is formed on the feed pedestal, the water supplied to the surface of the feed pedestal does not reach the feeding port, and the feed does not solidify at the feed outlet.

The step, which is formed on the feed pedestal, is not particularly limited in size, shape and the like as long as it can prevent water from reaching the surface of the feed pedestal at the feed feeding port. For example, it may be formed in a staircase shape or may be formed obliquely from directly below the feeding port (in this case, the upper stage surface of the feed cradle is only directly below the feeding port). Further, it is preferable that no feed is placed on the upper surface of the feed cradle.

The feeding port may be formed so that its horizontal length becomes shorter as it goes upward. For example, the feeding port can be formed in a triangular shape, an arc shape, or triangular steps in a stepwise shape. It can also be formed in a saw-tooth shape.

The step for placing the foot may be formed integrally with the water receiving tank on the front surface of the water receiving tank or separately from the water receiving tank. The step is formed separately from the feeding tank, and
When it is detachably formed, it can be applied to pigs of all seasons by attaching a step having a height according to the growing season of the pig.

[0014]

In the pig feeder of the present invention, the feed cradle holds the feed supplied from the feed storage chamber on the upper part thereof without dropping it into the water receiving tank. When the adjusting plate is pulled up, the opening of the feeding port is gradually narrowed, so that the amount of discharged feed becomes smaller than the moving distance of the adjusting plate.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pig feeder according to the present invention will be described with reference to the drawings.

Further, below the feeding port 6, there is a feed storage room 5.
Also, a feed receiving stand 10 formed integrally with the water receiving tank 2 is formed. The feed receiving stand 10 is formed so as to be substantially horizontal, and its tip portion is a convex wall 11 protruding upward. Are formed.

In order to supply the feed by the above pig feeder, the water is supplied from the nozzle 4 of the water supply pipe 3 to the water receiving tank 2, and the handle 9 is operated to close the adjusting plate 7 which is closed.
Move upwards. Then, the feeding port 6 is opened and the feed is discharged from the feed storage chamber 5. At this time, the adjusting plate 7
Since the newly opened opening area of the feeding port 6 gradually narrows as the number of feeds moves, the amount of discharged feed also gradually decreases, and a predetermined supply amount can be set accurately.

The feed discharged from the feeding port 6 is a feed receiving stand.
It is fed to 10 and eaten by pigs while maintaining this state.

FIG. 3 is a cross-sectional view of another pig feeder as seen from the side, and FIG. 4 is an enlarged cross-sectional view of portion A in FIG.

In FIG. 3, reference numeral 21 is a box body, and a box-shaped water receiving tank 22 that opens upward is formed in the lower part of the box body 21, and the upper surface is positioned slightly lower than the edge of the water receiving tank 22. Step 23 is performed. Further, in the water receiving tank 22, a nozzle 25 of a water supply pipe 24 for supplying water to the water 22 is provided so as to project inside. A feed storage chamber 26 for storing feed is provided above 22. A feed port 27 for discharging and supplying the feed is formed in the lower part of the feed storage chamber 26, and the feed port 27 is opened and closed. An adjusting plate 28 for adjusting the feed amount of feed is provided.
The adjusting plate 28 is connected to a shaft (not shown) and a handle (not shown) that can move back and forth.

As shown in FIG. 4, a feed tray 29 integrally formed with the feed storage chamber 26 and the water receiving tank 22 is formed in the lower portion of the feeding port 27 in a substantially horizontal direction. The pedestal 29 has a step formed below it near the pay opening 27, and is divided into an upper pedestal 30 and a lower pedestal 31.

The above-described feeding device for pigs is used for feeding the feed in substantially the same manner as the feeding device shown in FIGS. 1 and 2, but the feed discharged from the feeding port 27 is almost held in the lower pedestal 31. To be done. Therefore, the pig eats the feed on the lower pedestal 31, and the saliva drowned at that time spreads over the surface of the lower pedestal 31, but does not reach the upper pedestal 30 by the step. Further, since the pig puts the front leg on step 23 and eats the feed in this state, the front leg is not placed in the water receiving tank 22 or placed on the lower pedestal 31.

Next, the test results comparing the pig feeder of the present invention with the conventional pig feeder will be described.

I. Feeder management frequency test [Example 1] The pig feeder of the present invention was used. This pig feeder is substantially the same as the configuration shown in FIGS. 1 and 2, and has a feeding port with a bottom of 33 cm and a height of 5 cm. The feed cradle was installed horizontally and was 10 cm deep and 33 cm wide.

[Conventional Example 1] A commercially available feeder for pig farming was used. This pig feeder is
It has a structure similar to that shown in FIGS.
It was 5 cm and was 5 cm high. The feed cradle is formed diagonally downward at an angle of about 10 ° from the horizontal direction and has a depth of 8c.
The width was 33 cm and the width was 33 cm.

[Conventional Example 2] A commercially available pig feeder is used. This pig feeder is
It has a structure similar to that shown in FIGS.
It was 5 cm and was 5 cm high. The feed pedestal is formed in an arc shape so that it is diagonally downward at the tip and has a depth of 1
It was 1 cm and was 35 cm wide.

[Test Method] Five pig bunches were provided for each of Example 1 and Conventional Examples 1 and 2, and 15 pigs aged 4 months were housed in each pig bun, and each pig bun was fed for pig raising. One container was set up, and feed and drink were constantly fed by this. The feed is 3.2 mm in diameter for fattening pigs.
It is pellet feed and drinking water is tap water. After installing the pig feeder, visit each pig cluster four times a day for 15 days, adjust the handle that opens and closes the feeding mouth, and eliminate waste food in the water tank as necessary. Was recorded.

[Test Results] Table 1 shows the test results.

[0031]

[Table 1]

In the conventional example 1, when the feeding mouth is narrowed, the feed absorbs water such as saliva and is gelatinized from the end of the feeding mouth to cause clogging. On the contrary, when the feeding mouth is widened, the feed comes out too much. It fell into the water tank, it absorbed the spilled water of the drinking water and became a dango state, and if left unattended, it would have to be eliminated because it would spoil and the pigs would no longer eat. Moreover, the same tendency was observed in Conventional Example 2 although it was not as great as in Conventional Example 1.

In Example 1, once the adjustment of the first feeding port was completed, there was no effort to manage the feeder even with highly fluid pellet feed.

II. Growth performance test of raised piglets and generation test of waste food [Example 2] The same as Example 1.

[Conventional Example 3] The same as Conventional Example 1.

[Test Method] Fifteen piglets with an average age of 57 days per pig tuft (8 males,
(7 females) were housed, and one pig feeder was installed in each pig bun, whereby feed and drinking water were continuously fed for 60 days.
The feed was a pellet feed for raising piglets with a diameter of 3.5 mm. Then, the weight gain, feed supply, feed requirement (period feed intake / period weight gain), and the amount of feed removed from the water receiving tank were recorded.

[Results] The results are shown in Table 2.

[0038]

[Table 2]

The numerical values in the table are ratios of Example 2 when the value of Conventional Example 3 is 100.

In Conventional Example 3, the feed is not fed due to clogging of the feeding port, or conversely, the feed drops too much into the water receiving tank to absorb the spilled water and form a dango-like shape. Pigs were often in a state of lightness, which led to a slight inferior growth and greater variation in weight among piglets. In addition, there are quite a few feeds that have accumulated in the receiving tank and must be removed from the receiving tank in order to prevent spoilage, and as a result, the feed conversion rate has deteriorated.

In Example 2, since the beverage was appropriately fed from the feeding port, the piglets were kept fed with fresh feed, showed good growth, and had to be removed from the water receiving tank. There were no cases where this would not happen.

III. Growth performance test of fattening pigs and waste amount generation test [Example 3] The same as Example 1.

[Prior Art 4] This is the same as the prior art 2.

[Test Method] Fifteen piglets with an average age of 115 days per pig tuft (8 males)
Heads, 7 females) were housed, and one pig feeder was installed in each pig cell, whereby feed and drinking water were continuously fed for 42 days. The feed was a pellet feed with a diameter of 4.5 mm for raising piglets. Then, the weight gain, feed supply, feed requirement (period feed intake / period weight gain), and the amount of feed removed from the water receiving tank were recorded.

[Results] The results are shown in Table 3.

[0046]

[Table 3]

The numerical values in the table are the ratios of Example 3 when the value of Conventional Example 4 was set to 100. The tendency was exactly the same as in the case of domestic piglets.

[0048]
