Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for raising silkworms using artificial feed, a breeding apparatus or a production facility, and more particularly to aseptic breeding.

[0002]

2. Description of the Related Art Conventionally, as a method for rearing silkworms using an artificial feed, there is known a method for rearing silkworms by placing a net on the feed for so-called downward feeding (for example, JP-A-49- 117265). Also, when placing the net on artificial feed as described above and feeding downward, a method of raising the net and replacing old feed with new feed in the lower feed tray, or a feed tray with old feed It is known that the feeding and feeding can be performed at the same time by replacing the breeding tray with new feed (for example, Japanese Patent Publication No. 54-8591). In addition, in order to realize a factory for breeding silkworms, the whole breeding period of silkworms is divided into several equal periods, and the divided periods are divided into equal parts in the breeding rooms. It is known that they are raised and raised (for example, Japanese Patent Publication No. 57-9771).

However, a breeding method suitable for industrial production of silkworms and facilities or apparatuses therefor are still insufficient. The production of silkworms in Japan was about 400,000 tons in 1964, and cocoon yarn accounted for 45% of the total exports at that time. But,
The production of silkworms has decreased to about 90,000 tons in 1975, 50,000 tons in 1985, and 20,000 tons in 1991. This is due to the fact that cheap raw silk and silk products are imported from China and other foreign countries in large quantities, but silkworm production in Japan is largely due to the traditional breeding method, which is labor-free. A major cause is that the breeding method that enables mass production throughout the year has not been put to practical use. On the other hand, research on artificial feed is progressing, and it is now possible to breed silkworms only with artificial feed. Therefore, the present invention aims to provide a breeding method and a breeding apparatus that can perform large-scale production throughout the year without manpower, or a production facility, by utilizing the merit of this artificial feed. The purpose is to provide a breeding method suitable for breeding silkworms.
More specifically, it aims at the following points. First, one object of the present invention is to enable a large amount of silkworms to be bred in a space-saving manner as much as possible. Another object of the present invention is to reduce the difference in silkworm development and promote uniform silkworm growth. Another object of the present invention is to simplify the work required for raising silkworms. Another object of the present invention is to promote silkworm development by creating an environment suitable for silkworm growth. Further, another object of the present invention is to easily carry out the levitation work and to form a good quality cocoon. Another object of the present invention is to continuously breed silkworms having different fresh-up times. The present invention also provides
One purpose is to prevent contamination by various bacteria as much as possible. Another object of the present invention is to reliably disinfect and sterilize the breeding room. Another object of the present invention is to be able to continuously breed silkworms throughout the year.

By the first means of the present invention, it is possible to reduce the difference in environment between the upper position and the lower position, especially the difference in the growth of the silkworm caused by the temperature difference, and to promote the uniform growth of the silkworm. . By the second means of the present invention, it is possible to reduce the difference in environment between the upper position and the lower position, especially the difference in the growth of the silkworm caused by the temperature difference, and promote the uniform growth of the silkworm. Further, the work can be simplified because it is performed together with the replacement of the artificial feed. In particular, in sterilization or breeding in a sterile room, it is important to simplify and reduce the number of working steps in this way, since the invasion of foreign bacteria from the outside or the falling bacteria in the room has a great influence. By the third means of the present invention, the humidity in each breeding tray can be lowered by widening the spacing between the breeding trays. It is known that the humidity suitable for silkworms is preferably lowered according to the growth thereof, and the humidity suitable for silkworms is adjusted by changing the interval between breeding trays. In this way, by adjusting the spacing between the breeding trays so that the breeding tray has a humidity suitable for the silkworms, it is possible to prevent the silkworms from crawling out of the breeding trays. According to the fourth means of the present invention, it is possible to reduce the difference in environment generated between the upper position and the lower position, in particular, the difference in the growth of the silkworm caused by the temperature difference, and promote the uniform growth of the silkworm. Also,
The work can be simplified because it is performed together with the first feeding process and the second feeding process. In particular, in sterilization or breeding in a sterile room, it is important to simplify and reduce the number of working steps in this way, since the invasion of foreign bacteria from the outside or the falling bacteria in the room has a great influence. Further, by increasing the distance between the breeding trays, it is possible to reduce the humidity in each breeding tray and prevent the silkworm from crawling out. By the fifth means of the present invention, the spacing between the respective breeding trays is further changed to three levels in accordance with the growth of the silkworm, so that the environment inside each breeding tray can be made suitable for the silkworms. According to the sixth means of the present invention, in order to change the time to change the interval between the respective breeding trays depending on the humidity of the room or the degree of wetness of the artificial feed, it is possible to make the environment inside each breeding tray more suitable for silkworms. it can. By the seventh means of the present invention, the rearing tray transshipment step is provided at least seven times during the period of rearing silkworms. That is, the breeding trays are reloaded approximately every 3 days, and the difference in silkworm development caused by the temperature difference between the upper position and the lower position can be reduced, and uniform silkworm growth can be promoted. According to the eighth means of the present invention,
The breeding environment of breeding trays for breeding silkworms on the top can be made closer to the environment of other breeding trays.
Differences in silkworm development can be reduced and uniform silkworm growth can be promoted. According to the ninth means of the present invention, even if the breeding trays are reloaded, an empty breeding tray or lid is always arranged at the uppermost stage. As a result, it is possible to bring the breeding environment of the breeding tray for breeding the silkworms piled up at the top into the environment of other breeding trays. Further, the breeding tray located at the bottom is also easily affected by the outside (the bottom of the chamber), but an empty breeding tray or lid is always placed at this position as well. Therefore, the environment of each breeding tray can be made uniform. According to the tenth means of the present invention, the upper vine device is arranged in each of the breeding trays stacked in a plurality of stages to perform the upper vine, so that it does not require manual labor and does not require a large space separately. . Particularly, since the upper vine device is arranged on each breeding tray at the time of starting the upper vine, it is possible to prevent the environmental deterioration in the breeding tray. By the eleventh means of the present invention, the first upper step is provided, so that the work of the upper step is eliminated, a large space is not required separately, and the second upper step is performed. Since it is provided, it is possible to prevent cocooning in a high humidity state and to form a high quality cocoon. According to the twelfth means of the present invention, a plurality of breeding trays containing artificial feed are stacked, and a breeding method of breeding silkworms in each breeding tray can be efficiently performed. By the thirteenth means of the present invention, the silkworms that have risen from the breeding tray to the vines arranged in the respective breeding trays are further separated from each other in the gap between the breeding tray and the bottom of the breeding tray stacked on the mulberry. It is possible to prevent upset. First of the present invention
By the means of 4, there are a plurality of breeding rooms in which the temperature and humidity can be set independently, so that the breeding rooms can be used according to the growth of the silkworms, and it is possible to breed silkworms at different cleaning times at the same time. In addition, a separate work room is provided, and the artificial feed that is highly likely to invade various bacteria is not replaced in each breeding room.In addition, an entrance to the outside is provided only in this work room, and a pass box is provided at the entrance. By providing it, it is possible to prevent invasion of various bacteria into each breeding room. By the fifteenth means of the present invention, invasion of various bacteria into each breeding room can be prevented in the same manner as above. In addition, by changing the size of each breeding room, you can use a breeding room of the required size according to the stage of development of the silkworm, and it is possible to reduce the space that is not necessary for breeding silkworms. You can surely disinfect and sterilize. By the 16th means or the 18th means of the present invention, the size of the breeding room for 4th instar can be determined on the basis of the breeding room for 1st-3rd instar. Depending on the stage of silkworm development, a breeding room of the necessary size can be used, and the space that is not needed for breeding silkworms can be reduced, so that disinfection and sterilization to prevent germs can be reliably performed. . According to the seventeenth means or the nineteenth means of the present invention, the size of the 5th-age breeding room can be determined with reference to the narrowest 1st-3rd-age breeding room. Depending on the stage of silkworm development, a breeding room of the necessary size can be used, and the space that is not needed for breeding silkworms can be reduced, so that disinfection and sterilization to prevent germs can be reliably performed. . By the twentieth means or the twentieth means of the present invention, the size of the breeding room for the first to third instars can be determined on the basis of the widest breeding room for the fifth age. A breeding room of a necessary size can be used according to the growth means of the silkworm, and a space unnecessary for breeding the silkworm can be reduced. Therefore, disinfection and sterilization for preventing bacteria can be surely performed. 21st means or 2nd of this invention
By means of 3, the widest 5th breeding room as a standard,
The size of the breeding room for 4th instar can be determined. And you can use a breeding room of the necessary size according to the growth method of the silkworm,

EXAMPLES Examples of the method for raising silkworms according to the present invention will be described below. First, an apparatus used in the method for raising silkworms of the present invention will be described with reference to the drawings. FIG. 1 is a top view of one breeding tray, FIG. 2 is a cross-sectional view of the breeding tray, and FIG. 3 is an exploded perspective view showing the breeding tray and an upper vine device. Breeding tray 1
Forms a concave portion by the bottom surface 1a and the inner peripheral side plate 1b, and breeds silkworms in the concave portion. The inner peripheral side plate 1b is provided with a number of openings 1c for enhancing air permeability. The outer peripheral side plate 1d is connected to the inner peripheral side plate 1b by the edge portion 1e. The outer peripheral side plate 1d and the edge portion 1e ensure the strength of the breeding tray 1, prevent the bottom surface 1a from being deformed when the breeding tray 1 is moved, and allow the breeding trays 1 to be stacked and placed. .

An artificial feed 3 is placed on the bottom surface 1a of the breeding tray 1. The artificial feed 3 is laid with a thickness of 1.8 mm to 7.0 mm with a gap of at least 5 to 10 cm from the inner peripheral side plate 1b. The artificial feed 3 is laid with a space between the inner peripheral side plate 1b in this manner in order to prevent water condensed on the surface of the inner peripheral side plate 1b from dripping onto the artificial feed 3. When dew condensation water drops on the artificial feed 3, there is a risk that the artificial feed 3 will be submerged and dead during juvenile, and there is a risk that the artificial feed 3 will rot. Here, as the artificial feed 3, for example, a feed raw material containing tofu meal powder, mulberry leaf powder and defatted soybean powder as essential components, to which water is added, kneaded, and rolled into a flat plate is used (for example, Japanese Patent Laid-Open No. Hei 4).
-218343).

A breeding net 4 is laid on the artificial feed 3. This breeding net 4 uses a net made of an elastic material whose mesh is 1 cm square. This breeding net 4 is for promoting molting of silkworms. That is, the silkworm grows by repeating molting, but it is necessary to firmly fix the foot when carrying out molting. Further, the breeding net 4 is divided into three as shown in FIG. This needs to be separated according to the growth of the silkworm, and can be performed by dividing each breeding net 4 and moving each to a new breeding tray 1. The method of dividing the foil will be described later. In the figure, 5 indicates a silkworm. The breeding net 4 needs to have a size that covers the artificial feed 3, but if possible, it is preferable that the breeding nets 4 are laid so that adjacent breeding nets 4 overlap each other so that no gap is formed between the breeding nets 4. . This is when split foil, etc.
This is to prevent silkworms from remaining on the artificial feed 3 when the silkworms are moved by the rearing net 4. At this time, the overlapping portion is preferably about 1 cm to 3 cm. If there are too many overlapping parts, the number of silkworms between the breeding nets 4 will be different, and it will not be possible to divide the number of silkworms in a balanced manner. On the other hand, if there are too few overlapping parts, the periphery of the breeding net 4 will be separated. The silkworm in
This is because there is a possibility of crawling on the food after removing the breeding net 4.

There are several ways of stacking the breeding nets 4, but the most preferred method is to place the breeding nets 4 located at the center so as to overlap the breeding nets 4 on both sides as shown in the figure. Is. Since silkworms gather more in the peripheral portion than in the central portion, the area of the breeding net 4 located substantially in the center is enlarged and the silkworms are uniformly separated. In this method, two new breeding nets 4 are preliminarily placed on the new breeding tray 1 when the foil is tripled as described later.
It can be placed on both sides and the breeding net 4 with silkworms can be placed in the center. Therefore, before moving the breeding net 4 with silkworms, it becomes possible to place the new breeding net 4 on the new breeding tray 1 in advance.
In the subsequent breeding, it is possible to promote the uniform distribution of silkworms. Further, as another method of stacking the breeding nets 4, a method of placing them on a fish scale is preferable. That is, breeding tray 1
This is a method of placing the breeding net 4 in order from one side.
In this method, since the breeding nets 4 are placed in order from one side, it is possible to operate regularly when mechanically foil-dividing using the artificial feed exchange device. In addition, it is easy to deal with the case where the foil is divided into 3/2 times.

Next, the upper apparatus 2 will be described with reference to FIG. The upper worm device 2 includes a worm device 2a and an angle device 2 which arranges the worm device 2a at a predetermined height from the bottom surface 1a of the breeding tray 1.
b. The device 2a is formed of cardboard used for cardboard and the like, and is provided with a large number of cocoon forming chambers having openings in the vertical direction. However, a material such as polypropylene may be used. In this embodiment, the six instruments 2a are detachably mounted on the angle 2b. The angle 2b is a side plate 2c framed so as to fit into the recess of the breeding tray 1 with a slight gap.
And a partition plate 2d provided so as to divide the space surrounded by the side plate 2c into three. Further, on the inner peripheral surface of the side plate 2c and the side surface of the partition plate 2d,
Is provided with a stepped portion 2e. The step portion 2e is provided at a position about 2 cm from the bottom surface of the angle 2b, that is, the surface placed on the breeding tray 1. The thus-constructed upper vine device 2 is installed on the rearing tray 1 at the time when the 5th-instar silkworm starts the upper rear worm, and is removed from the rearing tray 1 after a certain period of time. Here, although not shown, it is preferable to provide a sealing material that covers the opening surface above the robot 2a. The sealing material may be the same as the material used for the pottery 2a, but may be made of thinner paper. Further, it is more preferable that the sealing material has ventilation holes to the extent that silkworms cannot pass through, and a net-shaped sealing material may be used. In this sealing material, silkworms crawling from inside the breeding tray to the pots placed in each breeding tray rise further in the gap with the bottom of the breeding tray stacked on the pot. It is to prevent that. In the above embodiment, the angle 2b is divided into three parts by the partition plate 2d, and the trawler 2a is divided into six parts. However, the invention is not limited to this.

Next, a breeding method using the above breeding tray 1 will be described. As shown in FIG. 4, a plurality of breeding trays 1 are stacked to breed. Although not shown, each breeding tray 1
As described with reference to FIGS. 1 to 3, silkworms are put therein together with an artificial feed and a breeding net. The breeding tray 1 at the top is preferably empty. This is because the upper surface of the uppermost breeding tray 1 is open, and thus unlike other breeding trays 1, the artificial feed is easily dried, which causes inconvenience. Therefore, the lid may be installed in place of the empty breeding tray. As shown in the figure, the breeding trays 1 are stacked on the trolley 5, but this is for the case where it is necessary to perform work such as food exchange at a place different from the breeding place, as will be described later. Especially when performing aseptic production of silkworms, it is preferable to separate the breeding place and the working place, and it is suitable for the movement in such a case.

A spacer 7 is provided between each breeding tray 1. The spacer 7 is not always provided during the breeding period of the silkworm, and the space interval is changed according to the growth of the silkworm. Details will be described later. The purpose of the spacer 7 is to improve the air permeability in the breeding tray 1 and prevent a bad environment due to excessive humidity. Although the method of directly stacking the breeding trays 1 on the dolly 6 has been described here, a rack capable of mounting a plurality of breeding trays 1 on the dolly 6 may be provided in advance. Then, the spacer 7 of the above-described embodiment is configured by making the space between the shelves changeable or by preparing a carriage having different space between the shelves.
It may fulfill the function of.

Next, a method of replacing the artificial feed will be described. FIG. 5 is a block diagram of the artificial feed changer seen from the top, and FIG. 6 is a block diagram of the same seen from the front. As also shown in the figure, the artificial feed changer mainly comprises a generally horizontal moving unit 8 and a vertical moving unit 9 and an arm unit 10 for holding a breeding tray or a breeding net. The arm part 10 moves up and down together with the vertically moving part 9,
The vertical movement unit 9 is provided so as to move up and down on the vertical rail 11. In addition, the vertical movement unit 9 and the vertical rail 11 are
Together with this, it moves in the left-right direction along the horizontal rail 12.

Now, the state where the breeding trays 1 are loaded on the four carts is shown, which are the stacking section 13, the feed supply section 14, the feeding cart section 15, and the stock section 16, respectively. As described above, three breeding nets are placed on the artificial feed on the breeding tray 1 of the breeding cart 15 and the breeding silkworms are placed on the respective breeding nets.

A new artificial feed and a new breeding net are placed on the breeding tray 1 of the feed supply unit 14. At this time, when the feed is changed before sleeping at the 2nd instar and at the time of exchanging the feed at the 4th instar silkworm, three new foils are separated, so that two new breeding nets are used at the time of exchanging the feed at the 5th instar silkworm. 3 /
One new breeding net is placed for doubling. When two new breeding nets are placed, it is preferable to open the center of the breeding tray 1 and place them on both sides. Also, place one new breeding net. When it is stored, it is preferable to place it in the center of the breeding tray. Breeding tray 1 for stacking section 13
Is after moving the silkworms onto a new artificial feed. The breeding tray 1 of the stock section 16 contains old artificial feed after the silkworms have been moved.

First, the trolley in which the breeding tray 1 being cultivated is laid in the trolley-carrying unit 15 and the trolley in which the breeding tray 1 having the new artificial feed and two new breeding nets mounted is loaded is the feed supply unit 14. To place. In addition, empty carts on which the breeding trays 1 are not stacked are arranged in the stacking section 13 and the stock section 16. The artificial feed changer is operated in this state. First, the horizontal movement unit 8 is moved on the horizontal rail 12 to the position of the carriage unit 15 during breeding. Next, the vertical movement unit 9 is lowered to a predetermined height, the arm portion 10 holds one breeding net on which silkworms are placed, and then the vertical movement unit 9 is raised. In this state, the horizontal movement unit 8 is moved on the horizontal rail 12 to the position of the feed supply unit 14.
Then, the vertical moving unit 9 is lowered again to a predetermined height,
Place the breeding net with silkworms on the breeding tray.

When the foil is tripled, one new breeding tray 1 is completed. When the foil is separated into 3/2 times, the same operation is repeated again, and another breeding net with silkworms is placed on the breeding tray to complete a new breeding tray. Therefore, the new breeding tray 1 is grasped by the arm portion 10, the vertical direction moving portion 9 is moved up, the horizontal direction moving portion 8 is moved to the position of the stacking portion 13, and the vertical direction moving portion 9 is lowered, Arm part 10
And the new breeding tray 1 is placed on the carriage of the stacking section 13.

In the same manner, the two breeding nets remaining on the breeding tray 1 of the cart 15 during breeding are also moved one by one to the new breeding tray 1 of the feed supply unit 14, and the new breeding tray 1 with the silkworms moved. Are stacked on the carriages of the stacking unit 13. In this manner, the breeding tray on the breeding-carrying carriage unit 15 from which all three breeding nets have been removed is moved to the stock unit 16. When all the breeding trays in the feed supply unit 14 have moved to the stacking unit 13, the work is stopped, and a new breeding tray placed on the stacking unit 13 is moved to the breeding room. Then, a breeding tray containing new artificial feed is placed again in the feed supply unit 14, and the feed replacement work is performed in the same manner as above.

In this embodiment, as described above, the stacking section 13, the feed feeding section 14, the feeding cart 15 and the stock section 16 are arranged on a straight line, and the feed feeding section 14 and the feeding cart 15 are arranged.
The following effects are obtained by arranging and adjacent to each other. First, since the breeding net on which silkworms are placed can be moved at the shortest distance, it is possible to minimize the falling of silkworms during movement. Also, since the moving time is short, it is possible to minimize the number of silkworms protruding from the remaining breeding net to the outside of the net. In addition, disposing a new breeding tray and a used dirty breeding tray separately on both sides is preferable for hygiene, especially when aseptic production is performed. Further, as in the present embodiment, by arranging the breeding trays in the longitudinal direction, the distance between the new breeding tray and the used dirty breeding tray can be further increased, and the horizontal moving unit 8 can be added. The moment force can be reduced, and it is not necessary to provide two horizontal rails 12 with each carriage interposed therebetween.

Next, a method for transposing the breeding tray will be described. Reloading of breeding trays can be performed using an artificial feed exchange device. That is, in the artificial feed exchanging method, the carts are arranged at the four positions of the stacking section 13, the feed supply section 14, the feeding cart section 15, and the stock section 16,
The rearing of breeding trays can be performed by using 2 of the 4 trays. For example, a breeding tray that is currently being raised is placed in the truck unit 15 during breeding,
An empty truck is arranged in the stock section 16. Then, as in the case of replacing the artificial feed, the horizontal movement unit 8 and the vertical movement unit 9
Are moved to move the breeding trays loaded in the dolly unit 15 during breeding to the dolly of the stock unit 16 in order from the top. At this time, if empty breeding trays are stacked at the top and bottom, the empty breeding trays will always be arranged at the top even after the breeding trays are reloaded. By transferring the breeding trays in this manner, the silkworms in the upper breeding tray and the silkworms in the lower breeding tray can be uniformly grown.

In a room having a closed space in which the air-conditioning environment is constant, 15 to 20 breeding trays are stacked and a temperature difference of approximately 2 degrees occurs when the breeding trays are about 2 meters high. In order to eliminate this temperature difference, forced circulation of indoor air can be considered, but the artificial feed dries quickly, and the artificial feed must be replaced earlier. Especially when breeding in a sterile room, it is important to keep access to the outside as much as possible, and it is not preferable that the artificial feed is exchanged earlier because the access to the outside will increase. Therefore,
This transshipment of breeding trays is a particularly effective method for raising silkworms uniformly in breeding in a sterile room. It should be noted that in the above embodiment, the method of moving sequentially from the uppermost stage has been described, but a method of collectively moving every two to three stages may be used.

Also, in the above-mentioned method of exchanging the artificial feed, there is substantially the effect of rearranging the feeding trays. That is, in the above-mentioned artificial feed replacement method, one breeding tray has three piles. Therefore, strictly speaking, when looking at the middle portion of the breeding tray, the original position is above the middle. It is possible that some of them are located higher in the newly piled mountains. However, the 1 or 2 tiers of breeding trays located at the top, or the 1 or 2 tiers of breeding trays located at the bottom, which are greatly affected by temperature differences, should be placed at the bottom or top of each new mountain. become.

Next, the equipment and devices required for aseptic rearing of silkworms will be described with reference to FIG. First, as a breeding room for silkworms,
A breeding room 20 for 1 to 3 years old, a breeding room 21 for 4 years old, and a breeding room 22 for 5 years old are provided. In addition, each breeding room is provided with entrances 20a, 21a, 22a. 1-3
The breeding room 20 for ages is a room for breeding from the time of sweeping up to the time when the silkworms of the 4th instar are raised, and the temperature is kept at about 28 to 29 degrees and the humidity is kept at about 90%. 4th-age breeding room 21
Is a room for breeding 4 to 5 year old silkworms. The temperature and humidity of the fourth-generation breeding room 21 are set lower than those of the first-third age breeding room 20, and the temperature is kept at around 26 degrees and the humidity is kept at around 80%. The 5th-age breeding room 22 is a room for breeding from the 5th-year-old silkworm to the completion of preparation of the vine. Here, the preparation of Kamikaju means the fixed period (about 2 days) after the silkworm starts the Kamikaze, and although the cocoon has not been completely formed, it is necessary to form the cocoon. It is a period until it moves into the container. The temperature and humidity of the 5th-age breeding room 22 are set to be lower than those of the 4th-age breeding room 21, and the temperature is around 24 degrees and the humidity is 75.
It keeps around%. It should be noted that each breeding room is most preferably a sterile room, but the 5th-age breeding room 22 does not cause any problem even under normal environment.

The upper worm chamber 23 is a place where after the preparation of the worm is completed, the silkworm forms a cocoon completely and the inside of the cocoon is managed until it becomes a perfect pupa. If the upper chamber 23 is clean, it does not necessarily have to be a sterile chamber, and from April to September, the window is opened and the upper chamber is kept in a normal environment. In other periods, an oil warm air heater, a ventilation fan, etc. are used as appropriate.

The aseptic working room 24 is a place where operations necessary for rearing silkworms up to the front of the vine are carried out, such as sweeping, replacement of artificial feed, and loading of rearing trays. This aseptic work room 2
No. 4 is set to a temperature and humidity lower than those of the breeding room 22 for 5th instar. It is also a sterile room.

A normal environment work chamber 25 is provided adjacent to the aseptic work chamber 24. The normal environment working room 25 is a place for kneading powder, which is a raw material for artificial feed, and water to produce a feed, and for cleaning a breeding tray carried out from the breeding room. Other facilities include a breeding tray storage room 26, an artificial feed raw material storage room 27, a powder processing room 28,
An office room 29, a machine room 30 and the like are provided. In addition, pass boxes 31a to 31e are provided at the entrances and exits to the sterile room to prevent invasion of pathogenic bacteria from the outside. The pass box 31a provided in the aseptic work room 24
Is for carrying in a new breeding tray, and the pass box 31b is for carrying out an old breeding tray. As shown in the figure, the pass box 31a is provided at a place distant from each breeding room, and the pass box 31b is provided nearer to each breeding room. This is to make it difficult for pathogenic bacteria from outside to enter the breeding rooms. In particular, since microbial contamination is most often caused by the entrance and exit of people, a changing room 32a and a shower room 32 are provided in this order between the office room 29 serving as the entrance and exit of people and the pass box 31e.
b, an air shower room 32c, and a changing room 32d are provided. A silkworm seed protection chamber 33 is provided adjacent to the aseptic work chamber 24. The aseptic work room 24 is provided with the artificial feed exchanging device 40 described in FIG. 5, and the stacking unit 13, the feed supply unit 14, and the rearing carriage unit 1 are provided as necessary.
5, the stock section 16 is arranged. And, in particular, it is preferable to arrange them in order as illustrated.

Next, the air conditioner will be briefly described. The machine room 30 is provided with a sterilization device 34 and a temperature / humidity control device 35, and adjusts the temperature / humidity after sterilizing the outside air. The temperature and humidity are aseptic work room 24 with the lowest greenhouse temperature.
Is set to conform to. The sterilized air passes through the duct 36 and is fed to each of the breeding rooms 20, 21, 2
2, aseptic working room 24 and 1st to 3rd year breeding room 20 and 4th age breeding room 21 and passage 37 provided between aseptic working room 24
Be led to. However, heaters 38a, 38b, 38c are provided in the blowing ducts of the breeding rooms 20, 21, 22 respectively.
Are installed and the temperature is adjusted to suit each breeding room. In addition, each breeding room 20, 21, 22 is provided with a humidifier 39a, 39b, 39c, respectively, and the humidity is adjusted to be suitable for each breeding room.

Next, the size of each breeding room will be described. The 4th-age breeding room 21 is wider than the 1-3rd-grade breeding room 20, and the 5th-age breeding room 22 is wider than the 4th-age breeding room 21. At this time, based on the size of the breeding room 20 for the first to third instars, the breeding room 21 for the fourth age is at least 1.5 times as large as the breeding room 20 for the first to third ages. Preferably. In addition, it is preferable that the 5th-age breeding room 22 is at least 3.4 times as large as the 1-3rd-age breeding room 20. Most preferably, the breeding room 2 for 4th instar
1 is 2.6 times as large as the breeding room 20 for 1 to 3 years old, and the breeding room 22 for 5 years is 6.4 times or more as large as the breeding room 20 for 1 to 3 years. On the other hand, based on the size of the 5th-age breeding room 22, the 1-3rd-age breeding room 20 is
It is preferable that the area is at least 15% or more of the breeding room 22 for 5th instar. In addition, it is preferable that the fourth-generation breeding room 21 is at least 30% larger than the fifth-age breeding room 22. In addition, most preferably, the breeding room 20 for 1 to 3 years old is 29% or more of the breeding room 22 for 5 years old and the breeding room 2 for 4 years old
1 is 66% or more of the breeding room 22 for 5th instar.

The optimum size of each breeding room is determined by the distribution foil according to the development of the silkworm. However, in the aseptic rearing of silkworms, it is important to minimize the introduction of pathogenic bacteria from the outside. The type and amount of artificial feed also affects the development of silkworms. Therefore, it is preferable to divide the foil when exchanging the feed. In aseptic rearing of silkworms, 3 times feeding and 4 times feeding are preferable. The three times feeding or the four times feeding is counted as one feeding at the time of sweeping. Therefore,
The triple feeding is a method of feeding twice other than at the time of sweeping. And, feeding three times is preferable when the silkworms are in their 4th and 5th instars. In addition, four times of feeding is performed before the second sleep. Therefore, the foil distribution is also performed at this timing.

First, in the case of feeding three times, it is assumed that the foil is tripled. If the breeding room for 1st to 3rd instars is 1, the breeding room for 4th instar needs to have a space of 3, and the breeding room for 5th instar needs to be 9.
However, the breeding period for the first to third instars is about twice as long as that for the fourth and fifth instars. Therefore, there are 4 breeding rooms and 5
Considering continuous use as much as possible without messing with the age-rearing room, the number of breeding rooms for the first-third-year-old needs twice.
That is, the breeding room for 1-3 years old is 2, the breeding room for 4 years old is 3,
If the 5th-incubation room is 9, it is possible to efficiently breed silkworms in each room. Therefore, the minimum necessary size of each room is 1.5 times as large as that of the breeding room for the 1st to 3rd years when the breeding room for the 4th to 3rd ages is used as a standard. It is preferable that the age-rearing room is 4.5 times or more as large as the 1-3-year-old breeding room. On the other hand, when using the 5th-age breeding room as the standard,
The breeding room for 1 to 3 years old is 17% or more of the breeding room for 5 years old,
It is preferable that the 4th-age breeding room is 33% or more of the 5th-age breeding room.

Next, description will be given of the case where the feeding is carried out three times and the foils are separated into triples, and the sweeping is performed every day. First, the number of breeding days is 12 days for the 1st to 3rd instars, 7 days for the 4th instars, and 8 days for the 5th instar, including the preparatory period. Therefore, the breeding room for 1st to 3rd instar needs 13 areas in 13 days, where 1 is 1 day. In addition, the 4th-age breeding room has three times as much as one day as compared with the 1st to 3rd-year-old breeding rooms. Also, since the 5th-age breeding room has 9 times the daily amount as compared to the 1-3rd-grade breeding room,
81 areas are required for 9 days. That is, when the breeding room for 1 to 3 years old is used as a reference, the breeding room for 4 years old is 1.9 times larger than the breeding room for 1 to 3 years old, and the breeding room for 5 years old is breeding for 1 to 3 years old. It is preferable that the space is 6.0 times or more the size of the chamber. On the other hand, when the 5th-age breeding room is used as a standard, the 1-3rd-age breeding room is 16% or more of the 5th-age breeding room and the 4th-age breeding room is 5
The size of the breeding room for age is preferably 30% or more.

In order to maintain the sterility, it is necessary to sterilize every breeding. In order to perform sterilization while continuing continuous breeding, it is necessary to partition each breeding room for at least one day and provide a spare room for each day for each breeding room. Therefore, 1 for each breeding room
If you add a day's spare space, 1 to 3 breeding rooms
The 4th and 4th-age breeding rooms must have a size of 27, and the 5th-age breeding room must have a size of 90. That is, when the breeding room for 1 to 3 years old is used as a reference, the breeding room for 4 years old is 1.9 times larger than the breeding room for 1 to 3 years old, and the breeding room for 5 years old is breeding for 1 to 3 years old. It is preferable that the area is at least 6.4 times as large as the room. On the other hand, when the breeding room for 5th instar is used as a standard, the breeding room for 1st to 3rd in
% Or more, it is preferable to make the 4th-age breeding room 30% or more of the 5th-age breeding room.

Next, the case of feeding four times will be described. 3
In the case of feeding once, it is separated into three times before sleeping at 2nd instar and 4th instar silkworm, and 3/2 times at 5th instar silkworm. At this time 2
The term “before sleep” refers to the middle of the breeding period for the first to third instars. Therefore, assuming that the area for cleanup is 1, the area for the first to third instars will be 4, because the area for 3 is additionally required for feeding before sleeping at the second instar. The 4th-age breeding room is 3 times as large as the 2nd-age sleep before feeding, so the space is 9 times, and the 5th-age breeding room is 3/2 times as large as the 4th-age breeding room, so 27/2 is needed. Become. Therefore, based on the breeding room for 1 to 3 years old, the breeding room for 4 years old is 2.25 times larger than the breeding room for 1 to 3 years old, and the breeding room for 5 years old is breeding for 1 to 3 years old. It is preferable that the area is at least 3.4 times as large as the room. On the other hand, when using the 5th-age breeding room as the standard,
The breeding room for 1 to 3 years old is more than 29% of the breeding room for 5 years old,
It is preferable that the 4th-age breeding room is 66% or more of the 5th-age breeding room.

Next, description will be given of the case where the feeding is carried out four times and the foils are separated into three times, three times, and 3/2 times, respectively, and swishing is performed every day. First of all, the number of breeding days is 1 to 3 years of age, and the feeding period before 2nd sleep is 6 days, and the remaining 1 to 3 years of age.
The 3rd instar period is 6 days, the 4th instar period and the 5th instar period are 7 days and 8 days, respectively, as described above. Therefore, 1
~ For the 3rd instar breeding room, assuming that 1 day for feeding before 2nd sleep before sleep is 1, the area for 7 days until feeding before 2nd sleep before sleep and 3 times as much as 7 days after splitting 28 areas, which is the total of 21 areas, are required. In addition, a 4-year-old breeding room has 9 days for 8 days, so 72 areas are available, and a 5-year-old breeding room has 9 days for one day.
× 3/2 is for 9 days, so a space of 121.5 is required. That is, when the breeding room for 1 to 3 years old is used as a standard, the breeding room for 4 years old is 2.6 times or more as large as the breeding room for 1 to 3 years old.
The age-rearing room is preferably 4.3 times or more as large as the 1-3-year-old breeding room. On the other hand, when the 5th-age breeding room is used as a standard, the 1st-3rd-age breeding room is 23% or more of the 5th-age breeding room and the 4th-age breeding room is 60% or more of the 5th-age breeding room. Is preferred.

In consideration of disinfection, if a preliminary space for one day is added to each breeding room, the breeding room for 1 to 3 years old is 32, the breeding room for 4 years old is 81, and the breeding room for 5 years old is 81 The breeding room needs to have a size of 135. That is, when the breeding room for 1st to 3rd instars is used as a standard, the breeding room for 4th instar is 2.5 times or more as large as the breeding room for 1st to 3rd instar. 4.2 of the chamber
It is preferable that the width is at least twice as large. On the other hand, when the 5th-age breeding room is used as a standard, the 1st-3rd-aged breeding room is 23% or more of the 5th-aged breeding room and the 4th-aged breeding room is 6th grade.
The width is preferably 0% or more.

Next, a method for aseptic rearing of silkworms will be described with reference to FIG. The case of raising 200,000 silkworms is used. First, the egg is taken out from the silkworm seed protection room 33 and sterilized in the aseptic work room 24. For disinfection of eggs, alcohol, formalin solution, Crite solution or the like is used. Sweeping is performed 4 days after disinfection of this egg. First, feed for 1st to 2nd instars is produced prior to the fresh sweep. Raw material storage room 27
The artificial feed is carried out from the container, and is hydrolyzed in the powder processing chamber 28 using a feed kneader. The artificial feed that has been kneaded with water is rolled by a rolling molding machine, and then cut into a required length according to the length of the breeding tray. At this time, the artificial feed should have a thickness of about 1.8 mm. This cut artificial feed is usually placed on a breeding tray in the environmental work room 25. This breeding tray is carried into the aseptic work chamber 24 through the pass box 31a, but is sterilized by steaming before being carried into a sterile feed. Prepare 20 breeding trays.
On the other hand, the breeding net is carried into the aseptic work room 24 separately. However, in the normal environment work room 25, the artificial feed may be placed on a breeding tray. Since three breeding nets are used for one breeding tray, 60 breeding nets are required.

Sweeping is performed in the aseptic work room 24. 1
Sweep 10,000 eggs into a single breeding tray. The rearing trays that have been swept up are stacked on the cart. At this time, it is preferable to place an empty breeding tray on at least the uppermost stage and the lowermost stage. The breeding trays thus stacked are carried into the breeding room 20 for 1 to 3 years old. On the 4th day after the sweeping, the rearing trays are reloaded. At this time the silkworm is 1
I am asleep. Reloading of the breeding trays is performed in the aseptic work room 24 using the artificial feed exchange device 40. The transshipment method is as described above. A 10 mm spacer is inserted between the breeding trays during this transshipment. It is preferable to remove the spacer once the day after this transshipment. The spacer removal work is also carried in by carrying the breeding tray into the aseptic work room 24. However, breeding trays will not be transshipped. At this time, the silkworm is in the state of second-instar silkworm. On the 7th day after sweeping, the feeding and rearing of the breeding trays are performed. The feeding at this time is feeding before the second sleep. Since the production of artificial feed and the feeding of the breeding tray to the aseptic work room 24 are the same as those at the time of sweeping, description thereof will be omitted. The material of artificial feed and the thickness of the feed are also the same. Since the feeding at this time will triple the foil, it is necessary to prepare 60 new breeding trays and 120 new breeding nets. Feeding, distribution and transshipment are as described above. At this time, no spacer is used between the breeding trays. In addition, after splitting, there is an average of 3,330 silkworms on one breeding tray.

On the 8th day after the cleanup, the silkworm enters 2 sleeps. The rearing trays are transshipped on the 9th day after sweeping. Naturally, this transshipment work is also performed in the aseptic work room 24. 1
The humidity of the third-generation breeding room 20 is detected, and if the humidity exceeds 90%, a 10-mm spacer is inserted between the breeding trays during transshipment. If the humidity is maintained at 90% or less, the spacer is not inserted at this time, and the spacer insertion work is performed two days later. However, instead of detecting the temperature in the breeding room, the degree of wetness of the artificial feed may be detected. On the 13th day after sweeping, feeding and rearing of breeding trays are performed. In this feeding as well, in order to triple the foil, 180 new breeding trays and 360 new breeding nets were added.
Prepare one. The artificial feed has a thickness of 2.5 mm. Also, transshipment is performed with the spacer inserted. The feeding tray after feeding and transshipment is moved to the 4th-incubation room 21.

On the 16th day after the sweeping, the breeding trays are reloaded. The spacer remains inserted. The rearing tray after transshipment is returned to the fourth-generation rearing room 21. On the 20th day after sweeping, the feeding and rearing of the breeding trays are performed. The silkworms are in the state of 5th instar silkworms. In feeding at this time, the foil is divided into 3/2. Therefore, 270 new breeding trays and 270 new breeding nets to be added are prepared. Feeding, distribution and rearranging of breeding trays are as described above. At this time, the thickness of the artificial feed is set to 7 mm and the spacer inserted between the breeding trays is changed to 20 mm. With this feeding, the number of silkworms on one breeding tray is 740. 5 after work
It is moved to the age breeding room 22.

On the 23rd day after the sweeping, it is preferable to further select the silkworms by feeding, transferring the breeding trays, and further developing. In the selection, the standard is 80%,
The delayed mouth is set to 20%, 400 breeding trays for standard are prepared, 100 breeding trays for delayed mouth are prepared, and one breeding tray is divided into about 400 silkworms. The number of breeding nets to be added is 690. The thickness of the artificial feed at this time is 7 mm, and the spacer inserted between the breeding trays is changed to 30 mm.

On the 26th day after the cleanup, the kamizai is started. At this time, an upper vine device is set in each breeding tray. In addition, as described above, when feeding or the like is performed on the 23rd day from the time of sweeping, the skimming device may be set at that time.
On the 28th day after the cleanup, the upper worm device and each breeding tray are removed and transferred to the worm chamber 23. It is cocooned on the 35th day after the cleanup.

By the way, when the silkworms are classified into the standard and the late-mouthing, the late-mouthing silkworms start to develop on the 29th day after the cleaning. Therefore, at this time, the superordinate device is installed in each breeding tray. Then, two days later, the upper vine device is removed from each breeding tray and transferred to the upper vine chamber 23. This late-dwelling silkworm is cocooned 3 days behind the standard.

As is clear from the description of the above embodiment,
INDUSTRIAL APPLICABILITY The present invention can reduce the difference in environment caused between the upper position and the lower position, particularly the difference in silkworm development caused by the temperature difference, and promote uniform silkworm growth. Further, according to the present invention, since the transshipment of the tray is performed together with the replacement of the artificial feed, the work can be simplified. In particular, in sterilization or breeding in a sterile room, it is important to simplify and reduce the work steps in this way. Further, according to the present invention, by adjusting the spacing between the breeding trays so that the humidity in the breeding trays is suitable for the silkworms, it is possible to prevent the silkworms from crawling out of the breeding trays. Further, according to the present invention, the humidity in each breeding tray can be lowered by widening the spacing between the breeding trays, and the silkworm can be prevented from crawling out. Further, according to the present invention, the spacing between the respective breeding trays can be changed to three levels in accordance with the growth of the silkworm, so that the environment inside each breeding tray can be made suitable for the silkworm.
