Description

[Technical field]

[0001] The present disclosure relates to vivarium and mobile vivarium. [Background technology]

[0002] Conventionally, there are techniques for removing feces and urine excreted by animals from the floor (for example, Patent Documents 1 and 2). In the technique of Patent Document 1, the floor is formed in a slatted shape, so that feces and urine are removed by dropping from the floor through the gaps in the slatted floor.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2-31626 [Patent Document 2] Special Publication No. 9-508785 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the animal is small, there is a risk that the animal's feet will get stuck in the gaps if the gaps in the slats are made large enough for the droppings to pass through. [Means for solving the problem]

[0005] The present disclosure can be realized in the following forms.

[0006] (1) According to a first embodiment of the present disclosure, a breeding facility for animals is provided. The breeding facility includes a housing chamber having a wall and a housing chamber floor for housing an animal in an internal space surrounded by the wall, and a floor portion installed in the internal space at a position vertically separated from the housing chamber floor, on which the animal sits. The floor portion has a lattice-shaped main body portion and an outer periphery surrounding the main body portion, and a second gap larger than the first gap, which is a gap in the lattice of the main body portion, is formed at least in a part between the wall and the outer periphery. According to this embodiment, the animal's urine passes through the lattice-shaped main body portion and flows toward the housing chamber floor. The animal's feces falls from the second gap between the wall and the outer periphery toward the housing chamber floor. The first gap, which is the size of the lattice of the main body portion, and the second gap can be set independently. By setting the size of the first gap smaller than the size of the animal's feet and setting the second gap large enough for the feces to fall, it is possible to remove the urine and feces from the floor portion while preventing the animal's feet from getting stuck in the first gap. (2) The breeding facility of the above embodiment may further include a collection plate installed between the housing chamber floor and the floor portion, and the collection plate may have a groove extending in the extension direction. According to this embodiment, by setting the width of the groove to a size that the animal feces cannot pass through, the feces do not fall into the groove and the urine comes into contact with the bottom of the groove, so that the feces and urine can be separated. Thus, the generation of an ammonia odor can be suppressed. (3) In the rearing facility of the above embodiment, the collection plate may be inclined so that the extension direction intersects with the horizontal direction. According to this embodiment, urine and feces move downward along the inclined collection plate by their own weight. Therefore, urine and feces can be collected efficiently. (4) The rearing facility of the above embodiment may further include a collection container for collecting excrement of the animals that has moved on the collection plate along the extension direction, the collection container having an opening for receiving the excrement and a filter installed at the opening. According to this embodiment, feces and urine can be separated by the filter. (5) In the rearing facility of the above embodiment, the collection plate may have one end and another end facing the one end in the extension direction, the other end being located lower than the one end, and the collection container may be installed below the other end. According to this embodiment, feces and urine can be collected with a simple structure. (6) In the breeding equipment of the above form, the recovery plate includes a first recovery plate portion having the groove, a second recovery plate portion having the groove, and a boundary portion, the first recovery plate portion having one end of a first recovery plate and the other end of a first recovery plate facing the one end of the first recovery plate in the extension direction, the other end of the first recovery plate being located lower than the one end of the first recovery plate, the second recovery plate portion having one end of a second recovery plate and the other end of a second recovery plate facing the one end of the second recovery plate in the extension direction, the other end of the second recovery plate being located lower than the one end of the second recovery plate, the other end of the first recovery plate facing the other end of the second recovery plate across the boundary portion, the boundary portion having one end of the boundary portion and the other end of the boundary portion facing the one end of the boundary portion, the other end of the boundary portion being located lower than the one end of the boundary portion, and the recovery container may be installed below the other end of the boundary portion. According to this embodiment, the feces and urine move along the grooves on the first and second collection plates toward the boundary. The feces and urine that have moved to the boundary further move on the boundary toward the collection container. Thus, the feces and urine can be collected in a concentrated manner. (7) In the breeding facility of the above embodiment, the breeding facility may further include a support portion provided between the outer periphery and the wall. According to this embodiment, even when an external force is applied to the breeding facility, displacement of the floor portion relative to the internal space can be suppressed. (8) In the breeding facility of the above embodiment, the second gap may be formed around the entire circumference of the outer periphery. The location on the floor where animals excrete feces varies from animal to animal. Therefore, according to this embodiment, it is possible to increase the probability that feces will fall through the second gap compared to when the second gap is formed only in a portion of the floor. (9) According to a second aspect of the present disclosure, there is provided a mobile breeding facility. This mobile breeding facility includes the breeding facility of the above aspect and a vehicle equipped with the breeding facility. According to this aspect, animals can be housed in the breeding facility and transported. The present disclosure can be realized in various forms, and in addition to the breeding facility described above, it can be realized in the form of, for example, a method for manufacturing a breeding facility.

[Diagram 3] FIG. 2 is a plan view of the breeding facility. [Figure 4] FIG. 2 is a side view showing the breeding facility without the second wall. [Diagram 5] FIG. [Figure 6] FIG. 11 is a perspective view of a recovery plate according to a second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] A. First embodiment: FIG. 1 is a schematic diagram showing a mobile breeding facility 1. As shown in FIG. 1, the mobile breeding facility 1 includes a vehicle 10 and breeding facility 20. The vehicle 10 has a towing vehicle 11 and a towed vehicle 12. The towed vehicle 12 moves by being towed by the towing vehicle 11. The towed vehicle 12 is equipped with breeding facility 20 for animals. Experimental animals EA are housed in the breeding facility 20. Note that the vehicle 10 is not limited to a configuration consisting of the towing vehicle 11 and the towed vehicle 12, and may be a configuration in which the vehicle 10 is a trailer and the breeding facility 20 is loaded on the bed of the trailer and moves.

[0009] The mobile breeding facility 1 is used, for example, to transport the animal EA between a place where the animal EA is kept and the residence of an experimenter who performs an animal experiment. The experimenter administers medication to the transported animal EA, performs treatment to cause organ dysfunction, etc. In other words, the mobile breeding facility 1 is used to transport the animal EA before an experiment or after treatment or medication has been performed. The animal EA is a micro pig, a pig, a monkey, a dog, a mouse, etc.

[0010] FIG. 2 is a perspective view of the breeding facility 20. FIG. 3 is a plan view of the breeding facility 20. FIG. 4 is a side view of the breeding facility 20 excluding the second wall 31b. FIG. 5 is a side view of the recovery plate 50 when the recovery plate 50 is viewed along the extension direction. FIG. 2 shows the X-axis, Y-axis, and Z-axis which are mutually orthogonal. The directions in which the arrows of the X-axis, Y-axis, and Z-axis point indicate the positive directions along the X-axis, Y-axis, and Z-axis, respectively. The positive directions along the X-axis, Y-axis, and Z-axis are respectively +X direction, +Y direction, and +Z direction. The directions opposite to the directions in which the arrows of the X-axis, Y-axis, and Z-axis point are respectively negative directions along the X-axis, Y-axis, and Z-axis. The negative directions along the X-axis, Y-axis, and Z-axis are respectively -X direction, -Y direction, and -Z direction. The directions along the X-axis, Y-axis, and Z-axis, regardless of whether they are positive or negative, are called the X-direction, Y-direction, and Z-direction, respectively. The same applies to the figures and explanations shown below. The breeding facility 20 is typically used in an installed state in which a floor 40, which will be described later, is parallel to a horizontal direction perpendicular to the vertical direction. Therefore, in the following explanation, the breeding facility 20 in the installed state will be described as an example. The +Z direction is the opposite direction to the vertical direction. The XY plane is parallel to the horizontal direction perpendicular to the vertical direction. The +X direction may be called rear, the -X direction may be called front, the +Z direction may be called up, the -Z direction may be called down, the +Y direction may be called right, and the -Y direction may be called left.

[0011] In this embodiment, the animal EA is a baby micropig. Therefore, the size of the feet of the micropig housed in the breeding facility 20 is about 10 mm. It is possible to train the micropig to defecate SI in a designated place. However, the micropig housed in the breeding facility 20 is not trained because it is only a newborn. Therefore, the place where the defecate SI is made varies depending on the individual. In addition, baby micropig has a high frequency of urinary UR. In this embodiment, the animal EA is kept in the breeding facility 20 for a long period of time, for example, about one week. Therefore, it is required to reduce the management burden. Taking such circumstances into consideration, the breeding facility 20 according to this embodiment is designed to ensure the safety of the micropig and to prevent the floor part 40 on which the micropig sits from becoming dirty due to the urine UR and feces SI excreted by the micropig.

[0012] As shown in FIG. 2, the breeding facility 20 includes a housing room 30 and a floor 40. The housing room 30 has a wall 31 and a housing room floor 32. The animal EA is housed in an internal space 34 surrounded by the wall 31 and the housing room floor 32. In this embodiment, the internal space 34 is a rectangular parallelepiped. The wall 31 includes a first wall 31a, a second wall 31b, a third wall 31c, and a fourth wall 31d. The second wall 31b faces the first wall 31a in the X direction. The fourth wall 31d faces the third wall 31c in the Y direction. The third wall 31c and the fourth wall 31d are sandwiched between the first wall 31a and the second wall 31b. In this embodiment, the fourth wall 31d forms the internal space 34 and is configured as a lattice-shaped door that opens the internal space 34. Specifically, the fourth wall 31d is removably attached to the first wall 31a and the second wall 31b. A gap is formed between the lower end of the fourth wall 31d and the storage chamber floor 32. The position of the lower end of the fourth wall 31d in the Z direction is approximately the same as the position of the floor portion 40 in the Z direction.

[0013] The plate-shaped floor 40 is installed in the internal space 34. The floor 40 has a lattice-shaped main body 41 and an outer periphery 42 surrounding the main body 41. Four legs 43 are attached to the floor 40. In this embodiment, the floor 40 and the legs 43 are made of metal. The floor 40 is installed at a position separated from the containment room floor 32 in the Z direction, which is the vertical direction. In the arrangement state of the breeding equipment 20 containing the animal EA, the floor 40 is located above the containment room floor 32. Since the main body 41 is lattice-shaped, the urine UR excreted by the animal EA passes through the gaps in the lattice of the main body 41 and flows toward the containment room floor 32.

[0014] As shown in Fig. 3, in this embodiment, the planar shape of the floor portion 40 is rectangular. Then, as shown in Fig. 2, legs 43 serving as supports are attached to each of the four corners of the floor portion 40 substantially perpendicularly to the floor portion 40. Since the floor portion 40 is supported by the four legs 43, the floor portion 40 is installed at a position separated from the accommodation chamber floor 32 in the Z direction, which is the vertical direction.

[0015] As shown in FIG. 3, the first gap, which is a gap in the lattice of the main body 41, is smaller than the size of the foot of the housed animal EA. In this embodiment, the size CA of the first gap is about 5 mm. Here, the size CA of the first gap is the maximum width of the hole in the lattice. Since the size CA of the first gap is smaller than the size of the foot of the animal EA, the foot of the animal EA is prevented from getting stuck in the gap of the main body 41. In addition, a gap is formed between the outer periphery 42 and the wall 31. In order to distinguish it from the first gap, the gap between the outer periphery 42 and the wall 31 is called the second gap. The size CB of the second gap is larger than the size CA of the first gap. The size CB of the second gap is large enough to allow the feces SI of the animal EA to pass through. Here, the size CB of the second gap is the minimum distance in the horizontal direction between the outer periphery 42 and the wall 31. In this embodiment, the size CB of the second gap is about 30 mm.

[0016] A support portion 44 is attached between the outer periphery 42 and the wall 31. In this embodiment, the support portion 44 is attached to each of the four sides of the floor portion 40. The support portion 44 connects the outer periphery 42 and the wall 31 with the second gap therebetween. This makes it possible to suppress the floor portion 40 from shifting in position relative to the internal space 34 and appropriately maintain the second gap even if vibrations are applied to the breeding equipment 20 while the vehicle 10 is moving. Note that, as another embodiment, the support portion 44 may be attached to at least one of the four sides of the floor portion 40, rather than to all four sides of the floor portion 40.

[0017] In this embodiment, the planar shape of the first gap of the floor 40 is rectangular, but the planar shape of the first gap is not limited to rectangular. For example, the planar shape of the first gap may be circular. When the planar shape of the first gap is circular, the size CA of the first gap is the diameter. In addition, the ratio of the size of the first gap to the width of the frame forming the lattice in the floor 40 is not limited to the ratio shown in FIG. 3. The ratio of the size of the first gap to the width of the frame forming the lattice may be determined by the weight of the animal EA placed on the floor 40. In other words, it may be determined by the load applied to the floor 40. In addition, in this embodiment, the second gap is formed on all four sides of the floor 40. And the size CB of the second gap is the same on all four sides of the floor 40. Not limited to this, the size CB of the second gap may be different from each other on each of the four sides of the floor 40.

[0018] In this embodiment, the animal EA is a micropig. Micropigs are clean animals, and therefore have the habit of excreting feces SI in a place far from where they sleep. For this reason, micropigs often excrete feces SI at the edge of the floor 40, that is, directly above the second gap. Furthermore, micropigs have the tendency to kick feces SI in order to move the feces SI far away. Therefore, not only when feces SI is excreted directly above the second gap, but also when feces SI is excreted in a place shifted from the second gap, the feces SI often falls down from the second gap due to being kicked by the micropig. In this way, the feces SI excreted by the animal EA falls down from the second gap. And, as described above, the urine UR excreted by the animal EA passes through the first gap of the main body 41. Therefore, feces SI and urine UR are removed from the floor 40, so that the floor 40 can be kept clean.

[0019] As shown in Fig. 4, the breeding facility 20 further includes a recovery plate 50 and a recovery container 60. The recovery plate 50 is installed between the floor 40 and the containment room floor 32. The recovery container 60 is installed on the containment room floor 32 near the fourth wall 31d. Note that in Fig. 2, the recovery plate 50, the recovery container 60, and the support portion 44 are omitted from illustration.

[0020] The recovery plate 50 has a rectangular outer shape. The recovery plate 50 has one end 51 and the other end 52. As shown in FIG. 5, the recovery plate 50 has a plurality of grooves 53 extending in the extension direction. In this embodiment, the plurality of grooves 53 are parallel to each other and are formed at equal intervals. Specifically, in this embodiment, the recovery plate 50 is a corrugated plate made of resin. The maximum width L1 of the groove 53 is about 1 / 2 the size of the feces SI. In this embodiment, the groove 53 has a shape in which the width of the groove 53 narrows toward the bottom 53a of the groove 53. This increases the possibility that the feces SI will not come into contact with the bottom 53a of the groove 53. The maximum width L1 of the groove 53 is about 5 mm. The depth L2 of the groove 53 is about 5 mm.

[0021] As shown in FIG. 4, the collection plate 50 is inclined so that the extension direction of the groove 53 intersects with the horizontal direction. Specifically, the other end 52 is installed so as to be located lower than the one end 51. As a result, the feces SI and urine UR move along the groove 53 toward the other end 52. As shown in FIG. 5, when the feces SI and urine UR move along the groove 53, the maximum width L1 of the groove 53 is about 1 / 2 the size of the feces SI, so that the feces SI moves without contacting the bottom 53a, and the urine UR flows along the bottom 53a. Therefore, the feces SI and urine UR can be moved toward the collection container 60 in a separated state. The shape of the groove 53 is not limited to the shape shown in FIG. 5. For example, the side surface of the groove 53 may be flat instead of curved. Also, the groove 53 does not have to have a shape in which the width of the groove 53 narrows toward the bottom 53a of the groove 53. For example, the width of the groove 53 may be uniform in the depth direction of the groove 53.

[0022] As shown in Fig. 4, the collection container 60 is placed below the other end 52 of the collection plate 50. The collection container 60 has an opening 61 for receiving excrement, i.e., feces SI and urine UR, and a filter 62 placed at the opening 61. In this embodiment, the filter 62 is a net with smaller mesh than the feces SI. This allows the urine UR to pass through the filter 62, and the feces SI is supported by the filter 62. Therefore, the feces SI and urine UR can be collected in a separated state.

[0023] In general, when the feces SI and urine UR are mixed, the feces SI becomes soft and is more likely to produce an ammonia odor. Furthermore, when the feces SI and urine UR are mixed, it often takes more time to remove the feces SI and urine UR than to remove them in a separated state. In this embodiment, the feces SI and urine UR are moved to the collection container 60 in a separated state by the collection plate 50. Then, in the collection container 60, the feces SI and urine UR are stored in a separated state. This makes it possible to suppress the ammonia odor. Furthermore, it is possible to reduce the management burden of the breeding facility 20.

[0024] According to the first embodiment described above, the breeding facility 20 includes the containment chamber 30 and the floor 40. The floor 40 is installed in the internal space 34 at a position vertically separated from the containment chamber floor 32. The floor 40 has a lattice-shaped main body 41 and an outer periphery 42. A second gap is formed between the wall 31 and the outer periphery 42. Therefore, the size of the lattice of the main body 41 and the size of the second gap can be set independently. By setting the first gap smaller than the size of the foot of the animal EA and setting the second gap large enough for the feces SI to fall, it is possible to remove urine UR and feces SI from the floor 40 while preventing the foot of the animal EA from getting stuck in the first gap. In addition, since the second gap is formed around the entire circumference of the outer periphery 42, it is possible to increase the possibility of removing the feces SI from the floor 40.

[0025] A collection plate 50 is installed between the containment chamber floor 32 and the floor portion 40. The collection plate 50 has a groove 53 extending in the extension direction. Therefore, by setting the width of the groove 53 to a size that prevents the feces SI of the animal EA from passing through, the feces SI does not fall into the groove 53, and the urine UR comes into contact with the bottom portion 53a of the groove 53, so that the feces SI and the urine UR can be separated. This makes it possible to suppress the generation of an ammonia odor.

[0026] Moreover, the collection plate 50 is inclined so that the extension direction intersects with the horizontal direction. Therefore, the collection of urine UR and feces SI can be performed efficiently. The breeding facility 20 also includes a collection container 60 that collects excrement that has moved along the extension direction. The collection container 60 has an opening 61 and a filter 62. This allows the filter 62 to separate the feces SI and the urine UR. The breeding facility 20 also includes a support portion 44 installed between the outer periphery 42 and the wall 31. Therefore, even if an external force such as vibration during transportation is applied to the breeding facility 20, the positional displacement of the floor portion 40 in the internal space 34 can be suppressed.

[0027] The mobile breeding facility 1 further includes a breeding facility 20 and a vehicle 10 that is equipped with the breeding facility 20. Thus, the animals EA can be housed in the breeding facility 20 and transported.

[0028] B. Second embodiment: 6 is a perspective view of a recovery plate 150 according to the second embodiment. The same members as those in the first embodiment are given the same reference numerals, and detailed descriptions thereof will be omitted as appropriate.

[0029] The recovery plate 150 according to this embodiment includes a first recovery plate portion 151 having a groove, a second recovery plate portion 152 having a groove, and a boundary portion 153. The first recovery plate portion 151, the second recovery plate portion 152, and the boundary portion 153 are each plate-shaped and have a rectangular planar shape. The first recovery plate portion 151 and the second recovery plate portion 152 have the same shape as the recovery plate 50 according to the first embodiment. The first recovery plate portion 151 has a first recovery plate one end portion 151a, a first recovery plate other end portion 151b, and a first recovery plate groove 151c as a groove extending in the extension direction. The first recovery plate other end portion 151b faces the first recovery plate one end portion 151a in the extension direction. The first recovery plate other end portion 151b is located below the first recovery plate one end portion 151a. The second recovery plate portion 152 has a second recovery plate one end portion 152a, a second recovery plate other end portion 152b, and a second recovery plate groove 152c as a groove extending in the extension direction. The second recovery plate other end portion 152b faces the second recovery plate one end portion 152a in the extension direction. The second recovery plate other end portion 152b is located below the second recovery plate one end portion 152a. The first recovery plate other end portion 151b faces the second recovery plate other end portion 152b across the boundary portion 153. The boundary portion 153 has a boundary portion one end portion 153a and a boundary portion other end portion 153b facing the boundary portion one end portion 153a. The boundary portion other end portion 153b is located below the boundary portion one end portion 153a. The recovery container 60 is installed below the boundary portion other end portion 153b.

[0030] In the collection plate 150 of the second embodiment, as in the first embodiment, the feces SI and urine UR move downward along the first collection plate groove 151c and the second collection plate groove 152c, i.e., toward the boundary portion 153. Then, the feces SI and urine UR are guided by the boundary portion 153 and move toward the collection container 60. In this way, the feces SI and urine UR move to the boundary portion 153, which is narrower than the length in the X direction of the collection plate 150, i.e., the width, so that the feces SI and urine UR can be collected together.

[0031] According to the second embodiment described above, the collection plate 150 includes the first collection plate portion 151 having the first collection plate groove 151c, the second collection plate portion 152 having the second collection plate groove 152c, and the boundary portion 153. The other end portion 151b of the first collection plate is located below the one end portion 151a of the first collection plate. The other end portion 152b of the second collection plate is located below the one end portion 152a of the second collection plate. The boundary portion 153 is sandwiched between the other end portion 151b of the first collection plate and the other end portion 152b of the second collection plate. The other end portion 153b of the boundary portion is located below the one end portion 153a of the boundary portion. Therefore, the feces SI and the urine UR are guided by the first collection plate portion 151 and the second collection plate portion 152, and move toward the boundary portion 153, and further move on the boundary portion 153 toward the other end portion 153b of the boundary portion. Therefore, fecal SI and urinary UR can be collected together.

[0032] C. Other embodiments: (C1) In the first embodiment, the collection plate 50 is inclined, but this is not limiting, and the collection plate 50 does not have to be inclined. The collection plate 50 has at least the grooves 53, so that it can keep the feces SI and the urine UR separated. If the collection plate 50 is not inclined, the feces SI and the urine UR on the collection plate 50 can be removed by a person. The same applies to the boundary portion 153 according to the second embodiment. That is, the boundary portion 153 according to the second embodiment is inclined with respect to the horizontal direction. As another embodiment, the boundary portion 153 is not inclined, and may be parallel to the horizontal direction.

[0033] (C2) In the above first embodiment, the second gap is formed around the entire circumference of the outer circumferential portion 42. In another embodiment, the second gap may be formed in at least a portion of the outer circumferential portion 42. By forming the second gap in at least a portion, the feces SI can drop through the second gap.

[0034] (C3) In the above first embodiment, the animal EA is described as a micropig, but the animal EA is not limited to a micropig. The type of the animal EA is not limited, and the breeding facility 20 has the second gap, so that at least feces SI excreted directly above the second gap can be removed from the floor 40. As described above, the breeding facility 20 is suitable for use in housing animals EA that excrete feces SI at the edge of the floor 40 and have a tendency to be clean.

[0035] (C4) In the second embodiment, no groove is formed in the boundary 153, but a groove extending from one end 153a of the boundary to the other end 153b of the boundary may be formed in the boundary 153. The width of the boundary 153 is not limited to the dimension shown in FIG. 6. For example, the width of the boundary 153 may be approximately the same as the width of the groove 53. This embodiment makes it easier for the feces SI and the urine UR to move toward the collection container 60. In addition, in FIG. 6, the first collection plate 151 and the second collection plate 152 are shown to have the same shape, but this is not limited to this. For example, the length of the first collection plate 151 in the X direction may be different from the length of the second collection plate 152 in the X direction. The inclination angle of the first collection plate 151 and the inclination angle of the second collection plate 152 may be different from each other.
