Description

[Detailed description of the invention]

[Industrial Field of Application] This invention particularly relates to a feeder for pigs. [Conventional technology] Conventionally, when raising pigs, pigs are fed with feed for the lactation period using a feeder during the lactation period, and after weaning, feed for the weaning period is given using a feeder for the weaning period. Feed was being given to the pigs. [Problem to be solved by the invention] If the feeding device is changed during the lactation period, the stress will cause the amount of food intake to not increase until weaning, and the number of days that growth will be stagnant will increase, increasing the number of days required for development. There was a problem. An object of the present invention is to solve the above problems and shorten the growth period of pigs before and after weaning. [Means for Solving the Problems] The feeding device of the present invention has a feed tray removably installed at the lower end of the box-shaped feeding device body, and has the above-mentioned shape on the top surface of the feed tray when the food tray is reversed and replaced. A feeding recess is provided in the feeder main body so as to move from the front to the rear, and a feed intake port for taking in the food in the feeding recess is provided on the front side of the feeder main body. It has a structure that is open over the entire surface. [Function] The feeding concave portion for receiving food is deviated to the upper surface and the recessed feed tray is taken out from the feeder main body, or it is reversed back and forth and replaced, and the feeding recess is moved to the front or rear part of the feeder main body. The feeding pattern is changed according to each stage of development. Further, the feed fed into the feeding recess is ingested through the feed intake opening opened on the front side of the feeder main body, thereby eliminating stress during feed intake. [Effects of the Invention] Since the present invention is configured as described above, the feeding mode can be changed according to the growth period of the pig, and the pig can be gradually acclimated to the feeding environment from the suckling period to the weaning period. This allows them to ingest food without stress. Therefore, it is possible to increase the feed intake of the pig from the lactation period to the weaning period, promote the growth of the pig, and shorten the breeding period required for the pig to reach a predetermined weight. [Example] Next, an example of the present invention will be described with reference to the drawings. The feeder main body 1 of the feeder K for pig farming is formed into a substantially box shape with an upper and front opening, and its lower end is connected to the lower end of the left and right side wall plates 1b, and the lower end of the rear wall plate 1c, respectively. A bottom plate 1a is formed horizontally, and the front portion of the bottom plate 1a projects forward of both side wall plates 1b. A strip-shaped reinforcing plate 1d is horizontally suspended near the lower end of the front edge of both side wall plates 1b, and above this reinforcing plate 1d, a vertical partition plate is removed from the front side of the feeder main body 1. The intake port 2 is opened over almost the entire surface in order to take in the feed. Between the side wall plates 1b of the feeder main body 1, there is a chute that tilts downward from the front upper end corner of the both side wall plates 1b to the rear in order to store the feed put into the feeder main body 1 and let it fall one after another. A plate 4 is installed in an inclined manner, and a vertically elongated adjustment hole 7 is provided in the vicinity of the center of the chute plate 4 . A bolt 5 inserted into an adjustment hole 7 of the chute plate 4 protrudes near the center of the lower side of the adjustment plate 6, which is slidably attached to the upper side of the chute plate 4. It is fastened to the chute plate 4 by a bolt 5 and a wing nut 8 screwed onto the bolt 5 so that the movement can be adjusted in the front upward direction and the rear downward direction. The opening width of the slit-shaped feeding port 9, which is opened to allow feed to fall without permission between the guide plate 12 attached near the lower end of the inner surface of the plate 1c, is adjusted by adjusting the movement of the adjusting plate 6. Therefore, it can be increased or decreased. On the bottom plate 1a of the feeder main body 1, a flat feed tray 10 made of concrete is removably placed to receive feed for lactation and weaning. A rectangular hole-shaped feeding recess 11 is provided on the upper surface of the food tray 10 .
One edge 10a of both front and rear edges 10a, 10b of
The distance from the feeding recess 11 to the other end edge 10b
The feed tray 10 is arranged at a position offset from the center of the bait tray 10 in a state where the interval is shorter than that of the bait tray 10.
When the one end edge 10a is installed with the front side, the feeding recess 11 moves to the front of the feed tray 10 and advances to the front inside the feeder main body 1, and the feed tray 10 is
When installed with the other end edge 10b facing forward and reversed, the feeding recess 11 is placed in the feed tray 10.
The position of the feeding recess 11 can be moved forward and backward in accordance with the growth period of the pig. Next, the operation and effects of the embodiment having the above configuration will be explained. In this example, the upper surface of the feed tray 10, which is removably installed at the lower end of the box-shaped feeder main body 1, is located at the front or rear part of the feeder main body 1 when the feed tray 10 is reversed and replaced. A feeding recess 11 is provided so as to be offset from the feed recess 11, and a feed intake port 2 for ingesting the food in the feeding recess 11 is provided almost entirely on the front side of the feeder main body 1. It is open. For this reason, for example, at the beginning of feeding, the food tray 10 is removed from the feeder main body 1, and the food tray 10
is used alone to feed the lactating period feed into the feeding recess 11 to feed the pigs in the early stages of lactation, and then, after a predetermined period of time has elapsed, in the later stages of lactation, the feed tray 10 is fed into the feeding recess 1.
1 is placed in the front part of the feeder main body 1, feed for the lactation period is fed into the feeding recess 11 to feed the pigs in the latter stage of lactation, and further, after a predetermined period of time has elapsed, in the later stage of lactation, The feed tray 10 is reversed and the feeding recess 11 is moved to the rear part of the feeder body 1, and feed for the weaning period is fed into the feeding recess 11 to rear the weaning pigs and adjust the feeding mode. If you change the feed according to the growth period of the pig, the pig will be accustomed to the feeding environment sequentially from the lactation period to the weaning period and will ingest the feed in a stress-free state. The increased intake promotes the growth of pigs before and after weaning, and the breeding period from suckling to weaning can be significantly shortened. In addition, since the feed intake port 2 is opened almost entirely in the feeder body 1 and the partition is removed from the feed intake port 2, the pigs are stressed by the partition of the feed intake port and the feed intake is reduced. It is possible to eliminate problems that result in a decrease in Table 1 shows the results of a comparative test on 12 pigs, comparing the changes in feed intake and body weight of pigs when using the feeder K described above and the changes in feed intake and body weight of pigs using the conventional feeding method. , shown in Table 2.

【table】

[Table] The above test results show that the feed intake and body weight of pigs using the feeder K of the present invention increased at each growth period compared to the feed intake and body weight of pigs using the conventional method. It was found that the difference in distance increased accordingly, and it was demonstrated that the growth of pigs was promoted in a short period of time by using feeder K.
