Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The pig breeding method of the embodiment of the present invention obtains edible meat from the pig by giving bubble drinking water containing ultrafine bubbles of air as gas to the pig.

Ultrafine bubbles are bubbles with a diameter of 1 μm or less, and those smaller than the wavelength of visible light cannot be visually recognized even if they are formed in a liquid. In addition, ultrafine bubbles have a smaller floating speed than microbubbles, which are bubbles having a diameter of 1 μm or more, and can stay in liquid for a long time. In addition, ultrafine bubbles have a larger surface area than microbubbles, have a self-pressurizing effect, and have a negative charging effect. On the basis of such characteristics, by feeding the water added with air ultra fine bubbles to the edible pig as drinking water, effects such as promotion of pig growth and improvement of pork quality can be obtained.

For example, in the case of Fuji Sakura varieties, edible pigs start fattening at a time of about 30 kg and reach a suitable weight of 110 kg for shipment, depending on the season and other conditions. Is the day. Here, by supplying bubble drinking water to which ultrafine bubbles of air are added to pigs in the fattening period, the shipment of the pigs can be shortened to, for example, about 75 to 80 days after the start of fattening. That is, the growth of the edible pig can be promoted and the fattening period can be shortened, as compared with the case of feeding normal drinking water that does not have ultrafine bubbles of air for fattening. If the fattening period is shortened, the pigs can be shipped quickly, and the raising efficiency of the pigs can be effectively increased. The period for feeding bubble drinking water to pigs may be a part of the fattening period or the whole period.

Also, feeding bubble drinking water to pigs can reduce the amount of feed consumed by pigs as compared to the case where regular drinking water is fed. Here, the effect of reducing feed consumption is remarkable when bubble drinking water is fed in the latter half of the fattening period of pigs. The amount of feed consumed by pigs depends on the weight of the pig, so the weight of the feed consumed in a given period in a pig pen that raises multiple edible pigs should be divided by the total weight of the edible pigs in this pig pen. It is preferable to perform the comparison based on the feed conversion rate thus obtained. For example, when bubble drinking water is supplied for at least a part of the fattening period, the feed requirement rate can be reduced by about 10% to 20% compared to when normal drinking water is supplied.

Also, by supplying the pig with bubble drinking water, the quality of the meat obtained from this pig can be improved as compared with the case of supplying normal drinking water. As an example of improving the quality of pork, when bubble drinking water is fed during at least part of the fattening period, it is possible to reduce drip loss of pork by about 30% to 40% compared to when normal drinking water is fed. it can.

In addition, as another example of improving the quality of pork, when the bubble drinking water was fed for at least a part of the fattening period, the intramuscular fat content of the pork was about 20% to 40% higher than when normal drinking water was fed. Can be increased. When the muscle fat content of pork increases, so-called marbling with red meat and sardines.

As another example of improving the quality of pork, when the bubble drinking water is fed for at least a part of the fattening period, the extension rate of the pork is increased by about 1% to 20% as compared with the case where the normal drinking water is fed. be able to. As pork stretch rate increases, tenderness increases.

In addition, as an example of improving other quality of pork, when bubble drinking water is fed to at least a part of the fattening period, the amount of polyunsaturated fatty acid contained in pork is higher than when normal drinking water is fed, It can be reduced by about 20% to 30%. The polyunsaturated fatty acid is, for example, linoleic acid, linolenic acid or the like, which causes a bad odor. Therefore, by supplying the bubble drinking water, the amount of polyunsaturated fatty acid contained in pork can be reduced and the malodor of pork can be prevented.

In addition, as an example of improving other quality of pork, when bubble drinking water is fed to at least a part of the fattening period, the amount of monounsaturated fatty acids contained in pork is higher than when normal drinking water is fed, It can be increased by about 1% to 5%. The monounsaturated fatty acid corresponds to, for example, palmitoleic acid and oleic acid, and has an action of lowering LDL (Low Density Lipoprotein) cholesterol of the human body and an action of improving the texture of meat. Therefore, LDL cholesterol can be reduced, and pork with a good texture can be obtained.

The ultrafine bubble-containing water of air used as drinking water in the present embodiment is not particularly limited as long as the diameter of the ultrafine bubbles of air is 1 nm or more and 1000 nm or less. If the diameter of ultrafine bubbles of air exceeds 1000 nm, the promotion of pig growth may be insufficient. The diameter of the ultrafine bubbles of air contained in the drinking water is preferably 10 nm or more and 500 nm or less, more preferably 20 nm or more and 300 nm or less. When the diameter of the air ultrafine bubbles contained in the drinking water is 20 nm or more and 300 nm or less, the growth of pigs can be effectively promoted. In the present embodiment, the diameter of the ultra fine bubbles was measured by the laser diffraction/scattering method.

The ultrafine bubble-containing water of air used as drinking water of the present embodiment has a concentration of ultrafine bubbles of air of 1×10 ⁷ cells/mL or more, and the upper limit is not particularly limited, but from the ease of production, It is 10 ¹² pieces/mL or less. If the concentration of ultrafine bubbles in the air is lower than 1×10 ⁷ cells/mL, promotion of pig growth may be insufficient. The concentration of ultrafine bubbles in air is preferably 1×10 ⁷ cells/mL or more and 3×10 ⁸ cells/mL or less, and particularly preferably 1×10 ⁸ cells/mL or more and 2×10 ⁸ cells/mL or less. Is. By setting the concentration of ultrafine bubbles in the air of drinking water to 1×10 ⁸ cells/mL or more and 2×10 ⁸ cells/mL or less, the growth of pigs can be effectively promoted.

　Bubble drinking water containing ultrafine bubbles of air may be fed to edible pigs at any time. Preferably, the bubble drinking water can be fed to pigs having a weight of more than 30 kg and having finished the piglet breeding period and being introduced into a fattening pig pen or the like to enter the fattening period. Alternatively, the fattening period may be divided into two or more, and the bubble drinking water may be supplied during the second and subsequent periods. For example, until the body weight reaches 70 kg is the fattening early period, and when the body weight exceeds 70 kg and reaches 110 kg is the late fattening period, bubble drinking water may be fed in the late fattening period. While normal drinking water is fed in the early period of fattening, and bubble drinking water is fed in the late period of fattening, the feed requirement rate in the late period of fattening can be effectively reduced.

The drinking water to be fed to edible pigs may contain the plant extract mixed fermented liquid in addition to the air ultra fine bubbles. The plant extract mixed fermented liquid is a plant-derived extract liquid obtained by mixing and extracting a liquid containing a plurality of types of plants containing at least aloe, an alcohol pickling liquid of Kidachi aloe, an alcohol pickling liquid of aloe vera, rice bran liquid, and sugar. A fermentation liquid of a liquid obtained by adding a mineral component and an ash component to a liquid containing a mixture of a mineral component and a mineral component.

The plant-derived extract solution of the above-mentioned plant extract mixed fermented solution comprises (a) a first liquid containing at least aloe, sugar and mineral, and (b) a second liquid containing at least aloe, sugar and salt ( c) Alcohol extract of plural kinds of plants containing aloe, sugar extract of plural kinds of plants containing aloe, liquid obtained by boiling and mixing plural kinds of plants, and alcohol extract of plural kinds of plant extracts It is preferable to include a third liquid containing and.

The first brown sugar aloe liquid can be adopted as the first liquid forming the plant-derived extract liquid of the above-mentioned plant extract mixed fermentation liquid. The first brown sugar aloe liquid can be prepared as follows. First, brown sugar 15 kg, brown sugar 15 kg, honey 7 kg, plum extract 500 cc, and concentrated mineral liquid 100 cc are mixed with 15 kg of yellowtail aloe, aged for 1 week, the liquid is squeezed, and the squeezed liquid is used as the first liquid. The concentrated mineral liquid was prepared by concentrating seawater 50 times. Aloe is used after being made into fine particles to a size of 1/100,000 mm. Hereinafter, plants such as aloe and aloe vera are treated in the same manner. This facilitates ionization.

The second brown sugar aloe liquid prepared as follows can be adopted as the second liquid forming the plant-derived extract liquid of the above-mentioned plant extract mixed fermentation liquid. 30 kg of aloe extract is mixed with 15 kg of brown sugar, 15 kg of brown sugar and 200 g of natural salt, and the mixed solution is boiled to obtain a second solution.

In the ultrafine bubble manufacturing device 26, a mixed fluid of water and air is pressure-fed by the cascade pump 23, and the casing from the supply pipe 41, which is a part of the return route 24 or the discharge route 25 on the upstream side of the ultrafine bubble manufacturing device 26, is discharged. The mixed fluid flows into 40. The mixed fluid that has flowed into the casing 40 is guided to the first and

second introduction paths

35 and 36 from the

inflow openings

35b and 36b on the outer surface of the miniaturization block 28. The mixed fluid guided to the first introduction path 35 is discharged into the first swirl chamber 31 through the discharge opening 35a, and forms a swirl flow in the first swirl chamber 31. A stable swirl flow is formed in the first swirl chamber 31 by the first introduction path 35 extending in the tangential direction of the first swirl chamber 31 and forming an inclination angle θ toward the other end. In addition, the mixed fluid guided to the second introduction passage 36 is discharged into the second swirl chamber 33 from the discharge opening 36 a, and forms a swirl flow in the second swirl chamber 33. Since the second introduction path 36 extends in the tangential direction of the second swirl chamber 33 and forms the inclination angle θ toward the other end, a stable swirl flow is formed in the second swirl chamber 33. The swirl flow of the mixed fluid in the first swirl chamber 31 is discharged from the first discharge hole 32 to the collision chamber 38, and the swirl flow in the second swirl chamber 33 to the collision chamber 38 from the second discharge hole 34. Is ejected. The swirling flows discharged from the first discharge hole 32 and the second discharge hole 34 are swirling in opposite directions, and thus collide in the collision chamber 38 with a large impact force. As a result, the gas of the mixed fluid is effectively atomized, and ultra nano bubbles are generated. The water containing the ultra nano bubbles of the air thus generated is guided from the collision chamber 38 to the

discharge passages

39, 39,... Through the

inflow openings

39a, 39a,. -Is discharged from the discharge pipe 42. The discharge pipe 42 is on the downstream side of the ultrafine bubble manufacturing device 26 in the return path 24 and the discharge path 25. The water containing the ultra fine bubbles of the air thus generated in the ultra fine bubble manufacturing device 26 is guided to the downstream side of the return path 24 and the discharge path 25. That is, water containing air ultrafine bubbles flows from the first ultrafine bubble producer 26A to the downstream side of the return route 24, and air ultrafine air from the second ultrafine bubble producer 26B to the downstream side of the discharge route 25. The water containing the bubbles flows. The bubbles produced by the ultrafine bubble production device 26 are not limited to only ultrafine bubbles, and microbubbles may be included depending on the operating conditions, or only microbubbles may be produced.

The bubble water production apparatus 3 adjusts the opening degree of the mixed air amount adjusting valve 29, the discharge flow rate or discharge pressure of the mixed water by the submersible pump 21 and the cascade pump 23, and the opening degree of the flow rate adjusting valve 27. The particle size and concentration of ultrafine bubbles and microbubbles from the discharge path 25 can be adjusted.

For example, when the opening degree of the flow rate adjusting valve 27 increases, the bubble concentration of ultrafine bubbles and/or microbubbles increases, the diameter of the bubbles also decreases, and the amount discharged from the discharge path 25 decreases. .. Along with this, the standard deviation of the diameters of the generated bubbles is reduced, the width of the distribution is reduced, and the diameters of the bubbles are concentrated in a narrow range of relatively small values. On the other hand, when the opening degree of the flow rate adjusting valve 27 decreases, the concentration of ultrafine bubbles and/or microbubbles decreases, the diameter of the bubbles increases, and the amount discharged from the discharge path 25 increases. .. Along with this, the standard deviation of the diameters of the generated bubbles expands, the width of the distribution expands, and the bubble diameters spread in a wide range from a relatively small value to a large value.

Further, when the discharge pressure of the cascade pump 23 increases, in the region where the discharge pressure is lower than 1 MPa, the concentration of bubbles of ultrafine bubbles and/or microbubbles increases, the diameter of the bubbles decreases, and the discharge is also reduced. The discharge amount from the path 25 increases. In the region where the discharge pressure is higher than 1 MPa, the concentration of ultrafine bubbles and/or microbubbles decreases and the bubble diameter increases. On the other hand, when the discharge pressure of the cascade pump 23 decreases, in the region where the discharge pressure is lower than 1 MPa, the concentration of bubbles of ultrafine bubbles and/or microbubbles decreases, the diameter of the bubbles expands, and the discharge is increased. The amount of emissions from the path 25 is reduced. In the region where the discharge pressure is higher than 1 MPa, the concentration of ultrafine bubbles and/or microbubbles increases and the bubble diameter decreases.

Further, by increasing the opening degree of the mixed air amount adjusting valve 29 of the ejector 22, the proportion of bubbles of 1 μm or more in the bubbles discharged from the discharge path 25 increases, while the mixed air amount adjusting valve 29 opens. By decreasing the degree, the proportion of bubbles having a diameter of 1 μm or more in the particle diameter of bubbles discharged from the discharge path 25 decreases. For example, when the air mixing amount of the ejector 22 is set to 0.4 L/min by the mixed air amount adjusting valve 29, the diameter of the bubbles discharged from the discharge path 25 is larger than 1 μm, but the ratio increases, and the bubbles become ultra fine bubbles. Micro bubbles are generated. On the other hand, if the air mixing amount of the ejector 22 is set to 0.1 L/min by the mixed air amount adjusting valve 29, most of the bubbles discharged from the discharge path 25 have a diameter of less than 1 μm, and thus the ultrafine bubbles are substantially formed. Only generated.

The bubble water production apparatus 3 also measures the concentration of ultrafine bubbles in the water discharged from the discharge path 25, and based on this measured value, the discharge pressure of the submersible pump 21 and the cascade pump 23 and the return path 24. The concentration of the ultrafine bubbles in the discharge path 25 can be adjusted by adjusting the flow rate of For example, when the concentration of the ultra fine bubbles in the discharge path 25 is lower than the target value, the opening degree of the flow rate adjusting valve 27 is increased to increase the flow rate in the return path 24, so that the ultra fine bubbles discharged from the discharge path 25. Concentration increases.

In addition, the bubble water producing device 3 is provided with a second flow rate adjusting valve on the upstream side of the second ultrafine bubble producing device 26B in the discharge path 25, and the opening degree of the second flow rate adjusting valve and the mixed air amount adjusting valve. By adjusting the opening degree of 29, the opening degree of the flow rate adjusting valve 27 of the return path 24, and the discharge pressure of the submersible pump 21 and the cascade pump 23, the diameter and concentration of the ultrafine bubbles discharged from the discharge path 25 can be adjusted. You may adjust.

The bubble water producing apparatus 3 is provided with a control device (not shown), and by this control device, the opening degree of the mixed air amount adjusting valve 29, the opening degree of the flow rate adjusting valve 27, and the opening of the second flow rate adjusting valve. The discharge pressure of the submersible pump 21 and the cascade pump 23 may be controlled to adjust the diameter and concentration of the ultrafine bubbles from the discharge path 25.

In this way, the bubble water producing apparatus 3 can stably form ultrafine bubbles of 50 to 70 nm. The return path 24, the flow rate adjusting valve 27, and the first ultrafine bubble manufacturing device 26A may not be provided. That is, the discharge path 25 may be provided only on the downstream side of the cascade pump 23 with the second ultrafine bubble manufacturing device 26B, and the ultrafine bubbles may be generated only by the second ultrafine bubble manufacturing device 26B.

In the above embodiment, the ultra fine bubble manufacturing device 26 includes the miniaturization block 28 that includes the first swirl chamber 31 and the second swirl chamber 33 that are coaxially formed symmetrically with respect to the plane perpendicular to the central axis.

The miniaturized block 128 has a generally cylindrical shape with a smaller diameter than the casing 140, and has the other end portion formed to have a larger diameter than the other portion and fitted to the inner surface of the other end portion of the casing 140. The miniaturization block 128 includes a processing flow path 130 through which a mixed fluid of water and gas is guided, a first eccentric supply path 131 as a swirl flow forming section that communicates with an upstream end of the processing flow path 130, and the processing flow.

The processing flow path 130 of the miniaturization block 128 is formed along the central axis of the miniaturization block 128 from the vicinity of one end surface of the miniaturization block 128 to the other end surface of the miniaturization block 128. One end of the processing channel 130 remains inside the miniaturization block 128 without penetrating one end surface of the miniaturization block 128, while the other end of the processing channel 130 has an opening at the other end surface of the miniaturization block 128. Is forming. The processing flow path 130 has a circular cross section and is formed so that the diameter increases from one end to the other end. A discharge pipe 42 is inserted into the opening at the other end of the processing flow path 130 so that the processing flow path 130 communicates with the discharge pipe 42.

Two first eccentric supply paths 131 of the miniaturization block 128 are formed so as to communicate with one end of the processing channel 130, as shown in FIG. 9 which is a cross-sectional view perpendicular to the central axis of the miniaturization block 128. There is. These two first eccentric supply passages 131 are arranged point-symmetrically with respect to the center of the processing flow passage 130. These first eccentric supply passages 131 extend substantially in the radial direction of the miniaturization block 128, form an inflow opening 131a on the outer peripheral surface of the miniaturization block 128, and discharge openings 131b on the inner peripheral surface of the processing flow passage 130. Is formed. These first eccentric supply passages 131 have a circular cross section and are formed so that the diameter becomes smaller from the inflow opening 131a toward the discharge opening 131b. The discharge opening 131b of the first eccentric supply path 131 is arranged at a position eccentric with respect to the center of the processing flow path 130 when viewed in the axial direction of the processing flow path 130. Here, in FIG. 8, the second eccentric supply passage 132 shows a shape of a vertical cross section along the central axis of the second eccentric supply passage 132, and the second eccentric supply passage 132 has a second surface in a plane passing through the central axis of the miniaturized block 128. The state in which the eccentric supply path 132 is cut is not shown.

The second eccentric supply passage 132 of the miniaturization block 128 is communicated with substantially the center of the processing flow passage 130 in the longitudinal direction, as shown in FIG. 10 which is a sectional view perpendicular to the central axis of the miniaturization block 128. Two are formed. These two second eccentric supply passages 132 are arranged point-symmetrically with respect to the center of the processing flow passage 130. These second eccentric supply passages 132 extend substantially in the radial direction of the miniaturization block 128, form an inflow opening 132a on the outer peripheral surface of the miniaturization block 128, and discharge openings 132b on the inner peripheral surface of the processing flow passage 130. Is formed. These second eccentric supply passages 132 have a circular cross section and are formed so that the diameter decreases from the inflow opening 132a toward the discharge opening 132b. The discharge opening 132b of the second eccentric supply passage 132 is arranged at a position eccentric with respect to the center of the processing flow passage 130 when viewed in the axial direction of the processing flow passage 130. The discharge opening 132b of the second eccentric supply passage 132 is eccentric to the discharge opening 131b of the first eccentric supply passage 131 on the opposite side with respect to the central axis of the processing flow passage 130. The first eccentric supply passage 131 and the second eccentric supply passage 132 of the miniaturization block 128 are arranged so as to form an angle of 90° with each other when viewed in the axial direction of the miniaturization block 128.

The ultrafine bubble manufacturing device 126 having the above-described configuration operates as follows. First, a mixed fluid of water and air is introduced into the casing 140 through the supply pipe 41. The mixed fluid that has flowed into the casing 140 is guided to the first and second

eccentric supply paths

131 and 132 from the

inflow openings

131a and 132a on the outer surface of the miniaturization block 128. The mixed fluid guided to the first eccentric supply passage 131 is discharged into the processing flow passage 130 from the discharge opening 131b and forms a swirling flow in the processing flow passage 130. Since the discharge opening 131b of the first eccentric supply path 131 is arranged at a position eccentric with respect to the center of the processing channel 130, a stable swirling flow is formed in the processing channel 130. The mixed fluid thus guided from the first eccentric supply passage 131 into the processing flow passage 130 becomes a swirling flow and flows from one end of the processing flow passage 130 to the other end. Further, the mixed fluid guided to the second eccentric supply passage 132 is discharged into the processing flow passage 130 from the discharge opening 132b. The discharge opening 132b of the second eccentric supply passage 132 is arranged at a position eccentric with respect to the central axis of the processing flow path 130, and is eccentric to the opposite side of the discharge opening 131b of the first eccentric supply passage 131. As a result, a swirl flow that is opposite to the swirl flow that has flowed through the processing flow path 130 is formed. The swirling flow of the mixed fluid discharged from the discharge opening 132b of the second eccentric supply passage 132 collides with the swirling flow flowing from the first eccentric supply passage 131. As a result, the gas of the mixed fluid is effectively atomized, and ultra nano bubbles are generated. The water containing the ultra nano bubbles of the air thus generated flows toward the other end of the processing flow path 130, and is discharged from the ultra fine bubble manufacturing device 126 through the discharge pipe 42.

When manufacturing the miniaturized block 128, the ultrafine bubble manufacturing device 126 of the above-described modification forms the processing flow path 130, the first eccentric supply path 131, and the second eccentric supply path 132 by cutting the single metal material. Can be formed. Therefore, the miniaturized block 128 can be easily manufactured with a small number of steps.

In the ultrafine bubble manufacturing device 126 of the above modification, the first eccentric supply passage 131 and the second eccentric supply passage 132 of the miniaturization block 128 form an angle of 90° with each other when viewed in the axial direction of the processing flow passage 130. Although arranged, they may be arranged to form an angle of 0 degree with each other. Further, although each of the first eccentricity supply passage 131 and the second eccentricity supply passage 132 of the miniaturization block 128 is provided by two, one or both of them may be provided by one.

Also, in the above-described embodiment, the bubble water production device 3 may employ a bubble water production device having another configuration. FIG. 11: is a schematic diagram which shows the bubble water manufacturing apparatus 103 of a modification. The bubble water manufacturing apparatus 103 includes a suction pump 121 as a first pump that sucks tap water as raw material water, fine bubble water, or a mixture of tap water and fine bubble water from the bubble water tank 2.

In parallel with the suction pump 121, an ejector 122 is provided as a mixer for mixing raw material water discharged from the suction pump 121 with air to form a mixed fluid of water and air. That is, the ejector 122 is provided between the suction side and the discharge side of the suction pump 121. To the ejector 122, an intake pipe for taking in air is connected to a mixed air amount adjusting valve 127 formed of a flow rate adjusting valve for adjusting the amount of air mixed with the mixed fluid. A gas tank 124 that stores air is connected to the upstream side of the mixed air amount adjustment valve 127. The gas tank 124 is preferably provided with a cleaning device for cleaning the air sucked from the atmosphere.

On the downstream side of the suction pump 121, the ultra fine bubble manufacturing device 26 that atomizes the mixed fluid air to form ultra fine bubbles is connected. Instead of the ultra fine bubble manufacturing device 26, a modified ultra fine bubble manufacturing device 126 may be connected. Between the suction pump 121 and the ultra fine bubble manufacturing device 26, a first hydraulic pressure sensor 141 for measuring the pressure of the liquid of the fluid guided to the ultra fine bubble manufacturing device 26 is provided. A cascade pump 123 as a second pump that sucks fluid is provided on the downstream side of the ultrafine bubble manufacturing device 26. A second hydraulic pressure sensor 142 that measures the pressure of the liquid of the fluid discharged from the ultra fine bubble manufacturing device 26 is provided between the ultra fine bubble manufacturing device 26 and the cascade pump 123. The controller 143 is configured to control the operation of the cascade pump 123 based on the measurement value of the second hydraulic pressure sensor 142.

On the downstream side of the cascade pump 123, a gas-liquid separator 125 that separates excess air remaining without being added to water from water containing ultrafine bubbles is connected. The air separated by the gas-liquid separator 125 is returned to the gas tank 124, while the water containing ultrafine bubbles is returned to the water tank 2. Here, as the first pump of the bubble water manufacturing apparatus 103, a volume pump such as a land pump may be used instead of the submersible pump. A pump other than the cascade pump may be used as the second pump, but a centrifugal pump is preferably used.

The bubble water production apparatus 103 of this modification is guided to the bubble water tank 2 by adjusting the opening degree of the mixed air amount adjusting valve 127 and the discharge flow rate or discharge pressure of the fluid of the suction pump 121 and the cascade pump 123. The particle size and concentration of ultrafine bubbles can be adjusted.

The bubble water manufacturing apparatus 103 also measures the concentration of ultrafine bubbles in the water in the bubble water tank 2, and based on the measured values, the discharge amounts of the suction pump 121 and the cascade pump 123, and the mixed air amount adjusting valve. By adjusting the opening degree of 127, the concentration of ultrafine bubbles in the bubble water tank 2 can be adjusted.

The bubble water producing apparatus 103 is provided with a second control device, and the opening degree of the mixed air amount adjusting valve 127 and the discharge flow rate or discharge amount of the fluid by the suction pump 121 and the cascade pump 123 are provided by the second control device. The particle size and concentration of the ultra fine bubbles in the bubble water tank 2 may be adjusted by controlling the pressure.

For example, in order to reduce the diameter of the bubbles contained in the fluid in the bubble water tank 2, the opening of the mixed air amount adjusting valve 127 is reduced to reduce the amount of air supplied to the ejector 122, and the suction pump 121 and the cascade. The operation of the pump 123 is continued. The fluid in the bubble water tank 2 is sucked by the suction pump 121 and guided to the ultra fine bubble manufacturing device 26, and the bubbles contained therein are atomized, sucked by the cascade pump 123, and returned to the bubble water tank 2. By circulating the fluid in the bubble water tank 2 through the suction pump 121, the ultra fine bubble maker 26, and the cascade pump 123, the diameter of bubbles contained in the fluid can be effectively reduced.

Further, for example, in order to increase the concentration of bubbles contained in the fluid in the bubble water tank 2, the opening degree of the mixed air amount adjusting valve 127 is increased to increase the air supply amount to the ejector 122, and the suction pump 121, The operation of the cascade pump 123 is continued. The fluid in the bubble water tank 2 is sucked by the suction pump 121, part of which is guided to the ejector 122, and air is added. The other part is guided from the suction pump 121 to the ultra fine bubble manufacturing device 26. The bubbles of the fluid are atomized by the ultra fine bubble maker 26, sucked by the cascade pump 123, and returned to the bubble water tank 2. By circulating the fluid in the bubble water tank 2 through the suction pump 121, the ejector 122, the ultrafine bubble manufacturing device 26, and the cascade pump 123, the concentration of bubbles contained in the fluid can be effectively increased.

In the ultrafine bubble producing device 26 of the bubble water producing apparatus 103, between 4 MPa and 6 MPa is provided between the upstream side and the downstream side, that is, between the fluid pressure of the supply pipe 41 and the fluid pressure of the discharge pipe 42. It is preferable to adjust the discharge amount of the suction pump 121 and the suction amount of the cascade pump 123 so that a pressure difference of 1 is generated. In this case, the pressure of the fluid in the supply pipe 41 is adjusted to be higher than the pressure of the fluid in the discharge pipe 42. As described above, by producing a pressure difference of 4 MPa or more and 6 MPa or less between the upstream side and the downstream side of the ultra fine bubble manufacturing device 26, the water containing the ultra fine bubble stably by the ultra fine bubble manufacturing device 26. Can be manufactured.

In this way, the bubble water producing apparatus 103 of the modified example can stably form ultrafine bubbles of 50 to 70 nm. Further, the bubble water producing apparatus 103 may produce water containing ultrafine bubbles of oxygen or hydrogen in addition to air. When producing water containing ultrafine bubbles of oxygen and hydrogen, excess oxygen and hydrogen not added to the water are separated by the gas-liquid separator 125 and returned to the gas tank 124, whereby oxygen and hydrogen are obtained. Can be prevented from leaking to the outside of the bubble water manufacturing apparatus 103. Therefore, when producing water containing ultrafine bubbles of oxygen or hydrogen, it is possible to effectively prevent inconveniences such as a fire caused by leakage of oxygen or hydrogen.

In the above embodiment, the miniaturization block 28 of the ultrafine bubble manufacturing device 26 has the first swirl chamber 31 and the second swirl chamber 33 as swirl flow forming parts, but the number is not limited to two, and three or more. You may have a swirl flow formation part. Further, the miniaturization block 128 of the ultra fine bubble manufacturing device 126 has the first eccentric supply passage 131 and the second eccentric supply passage 132 as the swirl flow forming portion, but the number is not limited to two, and three or more swirls are provided. It may have a flow forming part.

Further, in the above-described embodiment, the edible pig was fed with water containing ultrafine bubbles of air, but in addition to air, it may be fed with water containing ultrafine bubbles of other gas such as hydrogen and oxygen. Good. In addition to water, slightly acidic electrolyzed water or drinking water in which ultrafine bubbles are contained in water containing various other components may be supplied. When using water containing ultrafine bubbles of hydrogen and also when using water containing ultrafine bubbles of oxygen, the effect of promoting the growth of edible pigs and the effect of reducing the consumption of pig feed Was confirmed. In addition, the effect of promoting the growth of edible pigs was confirmed even when slightly acidic electrolyzed water was used.

In the example of the present invention, as drinking water for edible pigs, the following ultrafine bubble water containing ultrafine bubbles of air was prepared by the bubble water producing apparatus 3 described above.

All are average values per head. Table 7 shows the average daily weight gains in the early and late fattening periods and the feed requirement rate, both of which are the average values per head. Table 8 shows the measurement results of carcasses obtained from the edible pigs fattened in the test section and the control section. Tables 9 and 10 show the results of analyzing the meat quality of the loin meat obtained from the edible pigs fattened in the test group and the control group.

As can be seen from Table 6, regarding the growth rate, the average daily weight gain from the start of fattening to the arrival of shipment was significantly higher in the test groups 1 to 3, and the number of fattening days was shortened by up to 11 days compared with the control group. It was The feed intake during the test period was 381.7 kg/head on average in the control group, while 320.1 kg/head in average in test group 1 and 310.2 kg/head in average in test group 2. The average for Ward 3 is 389.4 kg/head. As a result, it is possible to reduce the feed of 61.6 kg/head in the test section 1 and reduce the feed of 71.5 kg/head in the test section 2.

Regarding the carcass measurement results, as can be seen from Table 8, in test area 2, the loin cross section is larger than in the control area. Regarding other measurement results, no significant difference was found between the test plot and the control plot. Regarding the meat quality of the loin meat, as can be seen from Table 9, in the test group 3, the drip loss is less than that in the control group and the intramuscular fat content is more than that in the control group.
