Definitions
- the present invention relates to a pig raising method for raising edible pigs, and an ultra fine bubble producing device for pig raising and a bubble drinking water producing device for pig raising used therein.
- Patent Document 1 discloses that it is possible to shorten the fattening period of edible pigs by using a feed containing a powder obtained by crushing the corms of plants.
- Patent Document 2 discloses that a feed containing olive squeezed slag and/or olive drop can provide a pork having a lipid containing a small amount of saturated fatty acids that increases the cholesterol level of the human body.

食用豚を養育する養豚事業において、豚の成長を促進して早期に出荷することは、経営効率を高める効果的な方法である。従来より、豚の成長を促進する方法として、豚の体重の増加を促進する成分を含有した飼料を給与することが提案されている(例えば、特許文献1参照)。特許文献1には、植物の球茎を粉砕して得た被粉を含有する飼料により、食用豚の肥育期間の短縮が可能であることが開示されている。
In the pig farming business that raises edible pigs, promoting pig growth and shipping it early is an effective way to improve management efficiency. Conventionally, as a method of promoting pig growth, it has been proposed to feed a feed containing a component that promotes weight gain of pigs (see, for example, Patent Document 1). Patent Document 1 discloses that it is possible to shorten the fattening period of edible pigs by using a feed containing a powder obtained by crushing the corms of plants.
また、養豚事業では、商品の競争力を高めるため、豚肉の品質を向上することが求められる。従来より、豚肉の品質を向上する方法として、肉質の食味を向上させる成分や、脂質の成分を改良する成分を含有した飼料を給与することが提案されている(例えば、特許文献2参照)。特許文献2には、オリーブ搾油滓及び/又はオリーブ落果を含有する飼料により、人体のコレステロール値を上昇させる飽和脂肪酸の少ない脂質を有する肉豚が得られることが開示されている。

以下、本発明の実施形態を、添付の図面を参照しながら詳細に説明する。
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
本発明の実施形態の養豚方法は、食用豚に、気体としての空気のウルトラファインバブルを含有するバブル飲用水を与えることにより、食用の肉を上記豚から得るものである。
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.
ウルトラファインバブルは、直径が1μm以下の気泡であり、可視光の波長よりも小さいものは、液体中に形成されても視認できない。また、ウルトラファインバブルは、直径が1μm以上の気泡であるマイクロバブルと比較して、浮上速度が小さく、液体中に長時間滞在することができる。また、ウルトラファインバブルは、マイクロバブルと比較して、表面積が大きく、自己加圧効果を有し、マイナス電荷の帯電作用を有する。このような特徴に基づき、空気のウルトラファインバブルを添加した水を飲用水として食用豚に給与することにより、豚の成長の促進や、豚肉の品質の向上等の効果が得られる。
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.
食用豚は、例えば富士桜種の場合、体重が約30kgの時期から肥育を開始し、出荷に適した110kgの体重に達するまでの期間は、季節等の条件により異なるが、概ね80日~90日である。ここで、空気のウルトラファインバブルを添加したバブル飲用水を、肥育期間の豚に給与することにより、豚の出荷を肥育の開始から例えば75日~80日程度に短縮することができる。すなわち、空気のウルトラファインバブルを有しない通常飲用水を給与して肥育するよりも、食用豚の成長を促進することができ、肥育期間の短縮を行うことができる。肥育期間を短縮すると、豚を早く出荷できるので、豚の養育効率を効果的に高めることができる。豚にバブル飲用水を給与する期間は、肥育期間の一部でもよく、全部でもよい。
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.
また、豚にバブル飲用水を給与することにより、豚の飼料の消費量を、通常飲用水を給与した場合よりも削減できる。ここで、飼料の消費量の低減効果は、豚の肥育期間のうちの後半にバブル飲用水を給与した場合に顕著である。なお、豚の飼料の消費量は、豚の体重によって異なるので、複数の食用豚を養育する豚舎で所定期間に消費された飼料の質量を、この豚舎に存在する食用豚の全ての質量で除して求められた飼料要求率により比較を行うのが好ましい。例えば、肥育期間の少なくとも一部にバブル飲用水を給与した場合、通常飲用水を給与した場合よりも、飼料要求率を約10%~20%低減させることができる。
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.
また、豚にバブル飲用水を給与することにより、この豚から得られる肉の品質を、通常飲用水を給与した場合よりも改善することができる。豚肉の品質が改善される例として、肥育期間の少なくとも一部にバブル飲用水を給与した場合、通常飲用水を給与した場合よりも、豚肉のドリップロスを約30%~40%低減させることができる。
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.
また、豚肉の他の品質の改善例として、肥育期間の少なくとも一部にバブル飲用水を給与した場合、通常飲用水を給与した場合よりも、豚肉の筋肉内脂肪含量を約20%~40%増加させることができる。豚肉の筋肉内脂肪含量が増加すると、赤身の肉にサシの入ったいわゆる霜降り状態となる。
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.

上記ウルトラファインバブル製造器26は、カスケードポンプ23により水と空気の混合流体が圧送され、戻し経路24や排出経路25のウルトラファインバブル製造器26の上流側の部分である供給管41から、ケーシング40内に混合流体が流入する。ケーシング40内に流入した混合流体は、微細化ブロック28の外側面の流入開口35b,36bから第1及び第2導入路35,36に導かれる。第1導入路35に導かれた混合流体は、吐出開口35aから第1旋回室31内に吐出され、第1旋回室31内に旋回流を形成する。第1導入路35が第1旋回室31の接線方向に延在すると共に他端に向けて傾斜角度θを成すことにより、第1旋回室31内に、安定した旋回流が形成される。また、第2導入路36に導かれた混合流体は、吐出開口36aから第2旋回室33内に吐出され、第2旋回室33内に旋回流を形成する。第2導入路36が第2旋回室33の接線方向に延在すると共に他端に向けて傾斜角度θを成すことにより、第2旋回室33内に、安定した旋回流が形成される。上記第1旋回室31内の混合流体の旋回流は、第1吐出孔32から衝突室38へ吐出され、上記第2旋回室33内の旋回流は、第2吐出孔34から衝突室38へ吐出される。これらの第1吐出孔32と第2吐出孔34から吐出された旋回流は、互いに反対方向に旋回しており、これにより大きな衝撃力を伴って衝突室38内で衝突する。その結果、互いの混合流体の気体が効果的に微細化され、ウルトラナノバブルが生成される。こうして生成された空気のウルトラナノバブルを含有する水は、衝突室38から流入開口39a,39a,・・・を経て排出通路39,39,・・・に導かれ、吐出開口39b,39b,・・・から排出管42に排出される。この排出管42は、戻し経路24や排出経路25のウルトラファインバブル製造器26の下流側である。こうしてウルトラファインバブル製造器26で生成された空気のウルトラファインバブルを含有する水は、戻し経路24や排出経路25の下流側に導かれる。すなわち、第1ウルトラファインバブル製造器26Aから戻し経路24の下流側に空気のウルトラファインバブルを含有する水が流れ、第2ウルトラファインバブル製造器26Bから排出経路25の下流側に空気のウルトラファインバブルを含有する水が流れる。なお、ウルトラファインバブル製造器26で製造されるバブルは、ウルトラファインバブルのみに限られず、運転条件に応じてマイクロバブルも含まれ、また、マイクロバブルのみが製造される場合もある。
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.
このバブル水製造装置3は、混合エア量調整弁29の開度と、水中ポンプ21及びカスケードポンプ23による混合水の吐出流量又は吐出圧力と、流量調整弁27の開度を調節することにより、排出経路25からのウルトラファインバブル及びマイクロバブルの粒径と濃度を調節することができる。
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.
例えば、流量調整弁27の開度が増大すれば、ウルトラファインバブル及び/又はマイクロバブルのバブルの濃度が増大すると共に、バブルの径が縮小し、また、排出経路25からの排出量が減少する。これと共に、生成されるバブルの径の標準偏差が縮小して分布の幅が縮小し、バブルの径が比較的小さい値の狭い範囲に集中する。一方、流量調整弁27の開度が減少すれば、ウルトラファインバブル及び/又はマイクロバブルのバブルの濃度が減少すると共に、バブルの径が拡大し、また、排出経路25からの排出量が増大する。これと共に、生成されるバブルの径の標準偏差が拡大して分布の幅が拡大し、バブルの径が比較的小さい値から大きい値にわたって広い範囲に拡散するようになる。
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.
また、カスケードポンプ23の吐出圧力が増大すると、この吐出圧力が1MPaよりも低い領域では、ウルトラファインバブル及び/又はマイクロバブルのバブルの濃度が増大すると共に、バブルの径が縮小し、また、排出経路25からの排出量が増大する。吐出圧力が1MPaよりも高い領域では、ウルトラファインバブル及び/又はマイクロバブルのバブルの濃度が低下すると共に、バブルの径が拡大する。一方、カスケードポンプ23の吐出圧力が減少すると、この吐出圧力が1MPaよりも低い領域では、ウルトラファインバブル及び/又はマイクロバブルのバブルの濃度が減少すると共に、バブルの径が拡大し、また、排出経路25からの排出量が減少する。吐出圧力が1MPaよりも高い領域では、ウルトラファインバブル及び/又はマイクロバブルのバブルの濃度が増大すると共に、バブルの径が縮小する。
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.
また、エジェクタ22の混合エア量調整弁29の開度を増大することにより、排出経路25から排出されるバブルのうち、1μm以上のバブルの割合が増加する一方、混合エア量調整弁29の開度を減少することにより、排出経路25から排出されるバブルの粒径のうち、1μm以上のバブルの割合が減少する。例えば、混合エア量調整弁29により、エジェクタ22の空気混合量を0.4L/minとすると、排出経路25から排出されるバブルの直径は、1μmを超えるものの割合が増大し、ウルトラファインバブルとマイクロバブルが生成される。一方、混合エア量調整弁29により、エジェクタ22の空気混合量を0.1L/minとすると、排出経路25から排出されるバブルの直径は1μmを下回るものが大半となり、実質的にウルトラファインバブルのみが生成される。
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.
また、このバブル水製造装置3は、排出経路25から排出される水のウルトラファインバブルの濃度を測定し、この測定値に基づいて、水中ポンプ21及びカスケードポンプ23の吐出圧力と、戻し経路24の流量を調節して、排出経路25のウルトラファインバブルの濃度を調節することができる。例えば、排出経路25のウルトラファインバブルの濃度が目標値よりも低い場合、流量調整弁27の開度を上げて戻し経路24の流量を増大させることにより、排出経路25から排出されるウルトラファインバブルの濃度が増大する。
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.
また、このバブル水製造装置3は、排出経路25の第2ウルトラファインバブル製造器26Bの上流側に第2流量調整弁を設け、この第2流量調整弁の開度と、混合エア量調整弁29の開度と、戻し経路24の流量調整弁27の開度と、水中ポンプ21及びカスケードポンプ23の吐出圧力を調節することにより、排出経路25から排出されるウルトラファインバブルの径と濃度を調節してもよい。
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.
上記バブル水製造装置3は、図示しない制御装置を設け、この制御装置により、上記混合エア量調整弁29の開度と、上記流量調整弁27の開度と、上記第2流量調整弁の開度と、上記水中ポンプ21及びカスケードポンプ23の吐出圧力を制御して、排出経路25からのウルトラファインバブルの径と濃度を調節してもよい。
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.
このようにして、上記バブル水製造装置3により、安定して50~70nmのウルトラファインバブルを形成することができる。なお、戻し経路24と流量調整弁27と第1ウルトラファインバブル製造器26Aは、設けなくてもよい。すなわち、カスケードポンプ23の下流側に、排出経路25を第2ウルトラファインバブル製造器26Bのみを設け、第2ウルトラファインバブル製造器26Bのみによりウルトラファインバブルを生成してもよい。
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. However, other ultra fine bubble manufacturing machines for pig farming may be used. FIG. 8 is a vertical sectional view showing a modified ultrafine bubble manufacturing device for pig farming. 9 is a cross-sectional view taken along arrow D in FIG. 8, and FIG. 10 is a cross-sectional view taken along arrow E in FIG.

このウルトラファインバブル製造器126は、一端が供給管41に連結され、他端が微細化ブロック128に連結された概ね円筒形状のケーシング140を有する。微細化ブロック128は、ケーシング140よりも小径の概ね円筒形状を有し、他端部分が他の部分よりも大きい径に形成されてケーシング140の他端部の内側面に嵌合している。この微細化ブロック128は、水と気体の混合流体が導かれる処理流路130と、この処理流路130の上流端に連通する旋回流形成部としての第1偏心供給路131と、上記処理流路130の長さ方向の略中央に連通する旋回流形成部としての第2偏心供給路132が内部に形成されている。処理流路130の中心軸を通る断面において、第1偏心供給路131の中心軸と、第2偏心供給路132の中心軸は、処理流路130の中心軸に対して直角に延在している。
The ultrafine bubble manufacturing device 126 has a substantially cylindrical casing 140 having one end connected to the supply pipe 41 and the other end connected to the miniaturization block 128. 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. A second eccentric supply passage 132 as a swirling flow forming portion that communicates with substantially the center of the passage 130 in the longitudinal direction is formed inside. In a cross section passing through the central axis of the processing channel 130, the central axis of the first eccentric supply channel 131 and the central axis of the second eccentric channel 132 extend at right angles to the central axis of the processing channel 130. There is.
微細化ブロック128の処理流路130は、微細化ブロック128の中心軸に沿って、微細化ブロック128の一端面の近傍から、微細化ブロック128の他端面に至るまで形成されている。処理流路130の一端は、微細化ブロック128の一端面に貫通することなく微細化ブロック128内に留まっている一方、処理流路130の他端は、微細化ブロック128の他端面に開口を形成している。この処理流路130は、円形断面を有し、一端から他端に向かうにつれて径が増大するように形成されている。処理流路130の他端の開口には、排出管42が挿入されて、処理流路130が排出管42に連通している。
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.
微細化ブロック128の第1偏心供給路131は、微細化ブロック128の中心軸と直角の断面図である図9に示すように、処理流路130の一端に連通するように2本形成されている。これらの2つの第1偏心供給路131は、処理流路130の中心に関して点対称に配置されている。これらの第1偏心供給路131は、微細化ブロック128の概ね径方向に延在し、微細化ブロック128の外周面に流入開口131aを形成し、処理流路130の内周面に吐出開口131bを形成している。これらの第1偏心供給路131は、円形断面を有し、流入開口131aから吐出開口131bに向かうにつれて径が小さくなるように形成されている。第1偏心供給路131の吐出開口131bは、処理流路130の軸方向視において、処理流路130の中心に対して偏芯した位置に配置されている。ここで、図8において、第2偏心供給路132は、この第2偏心供給路132の中心軸に沿った縦断面の形状を示しており、微細化ブロック128の中心軸を通る面で第2偏心供給路132を切断した様子を示していない。
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.
微細化ブロック128の第2偏心供給路132は、微細化ブロック128の中心軸と直角の断面図である図10に示すように、処理流路130の長さ方向の略中央に連通するように2本形成されている。これらの2つの第2偏心供給路132は、処理流路130の中心に関して点対称に配置されている。これらの第2偏心供給路132は、微細化ブロック128の概ね径方向に延在し、微細化ブロック128の外周面に流入開口132aを形成し、処理流路130の内周面に吐出開口132bを形成している。これらの第2偏心供給路132は、円形断面を有し、流入開口132aから吐出開口132bに向かうにつれて径が小さくなるように形成されている。第2偏心供給路132の吐出開口132bは、処理流路130の軸方向視において、処理流路130の中心に対して偏芯した位置に配置されている。この第2偏心供給路132の吐出開口132bは、第1偏心供給路131の吐出開口131bと、処理流路130の中心軸に関して反対側に偏心している。上記微細化ブロック128の第1偏心供給路131と第2偏心供給路132は、微細化ブロック128の軸方向視において、互いに90°の角度を成すように配置されている。
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.
上記構成のウルトラファインバブル製造器126は、次のように動作する。まず、水と空気の混合流体が供給管41を通してケーシング140内に導かれる。ケーシング140内に流入した混合流体は、微細化ブロック128の外側面の流入開口131a,132aから第1及び第2偏心供給路131,132に導かれる。第1偏心供給路131に導かれた混合流体は、吐出開口131bから処理流路130内に吐出され、この処理流路130内に旋回流を形成する。第1偏心供給路131の吐出開口131bが処理流路130の中心に対して偏芯した位置に配置されていることにより、処理流路130内に、安定した旋回流が形成される。こうして第1偏心供給路131から処理流路130内に導かれた混合流体は、旋回流となって処理流路130の一端から他端に向かって流れる。また、第2偏心供給路132に導かれた混合流体は、吐出開口132bから処理流路130内に吐出される。上記第2偏心供給路132の吐出開口132bは、処理流路130の中心軸に関して偏芯した位置に配置されていると共に、第1偏心供給路131の吐出開口131bと反対側に偏心していることにより、処理流路130を流れた旋回流に対して反対向きの旋回流を形成する。この第2偏心供給路132の吐出開口132bから吐出された混合流体の旋回流が、第1偏心供給路131から流れて来た旋回流と衝突する。その結果、互いの混合流体の気体が効果的に微細化され、ウルトラナノバブルが生成される。こうして生成された空気のウルトラナノバブルを含有する水は、処理流路130の他端に向かって流れ、排出管42を通ってウルトラファインバブル製造器126から排出される。
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.
上記変形例のウルトラファインバブル製造器126は、微細化ブロック128を製造する際、単一の金属材料に対する切削加工により、処理流路130、第1偏心供給路131及び第2偏心供給路132を形成できる。したがって、少ない工数により容易に微細化ブロック128を製造できる。
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.
上記変形例のウルトラファインバブル製造器126において、微細化ブロック128の第1偏心供給路131及び第2偏心供給路132は、処理流路130の軸方向視において互いに90°の角度を成すように配置されたが、互いに0度の角度を成すように配置されてもよい。また、微細化ブロック128の第1偏心供給路131及び第2偏心供給路132は、いずれも2個ずつ設けたが、いずれか一方又は両方を1個ずつ設けてもよい。
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.
また、上記実施形態において、バブル水製造装置3は、他の構成のバブル水製造装置を採用してもよい。図11は、変形例のバブル水製造装置103を示す模式図である。このバブル水製造装置103は、バブル水タンク2から原料水としての水道水、ファインバブル水、又は、水道水とファインバブル水の混合した水を吸引する第1ポンプとしての吸引ポンプ121を備える。
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.
上記吸引ポンプ121と並列に、吸引ポンプ121から吐出される原料水に、空気を混合して水と空気の混合流体を形成する混合器としてのエジェクタ122が設けられている。すなわち、吸引ポンプ121の吸入側と吐出側の間に、エジェクタ122が介設されている。エジェクタ122には、空気を取り入れる吸気管に、混合流体に混合する空気の量を調整するための流量調整弁で形成された混合エア量調整弁127が連結されている。混合エア量調整弁127の上流側には、空気を貯留する気体タンク124が接続されている。この気体タンク124は、大気から吸入した空気を浄化する清浄装置を設けるのが好ましい。
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.
上記吸引ポンプ121の下流側には、混合流体の空気を微細化してウルトラファインバブルを形成する上記ウルトラファインバブル製造器26が接続されている。ウルトラファインバブル製造器26に替えて、変形例のウルトラファインバブル製造器126を接続してもよい。上記吸引ポンプ121とウルトラファインバブル製造器26との間には、ウルトラファインバブル製造器26に導かれる流体のうちの液体の圧力を測定する第1液圧センサ141が設けられている。ウルトラファインバブル製造器26の下流側には、流体を吸引する第2ポンプとしてのカスケードポンプ123が設けられている。ウルトラファインバブル製造器26とカスケードポンプ123との間には、ウルトラファインバブル製造器26から吐出される流体のうちの液体の圧力を測定する第2液圧センサ142が設けられている。この第2液圧センサ142の測定値に基づいて、制御装置143によりカスケードポンプ123の動作を制御するように構成されている。
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.
カスケードポンプ123の下流側には、ウルトラファインバブルを含有する水から、水に添加されずに残留した余剰の空気を分離する気液分離器125が接続されている。気液分離器125で分離された空気は、気体タンク124に戻される一方、ウルトラファインバブルを含有する水は、水タンク2に戻されるようになっている。ここで、バブル水製造装置103の第1ポンプとしては、水中ポンプ以外に、陸上ポンプ等の容積ポンプを用いてもよい。また、第2ポンプとしては、カスケードポンプ以外のポンプを用いてもよいが、遠心ポンプを用いるのが好ましい。
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.
この変形例のバブル水製造装置103は、混合エア量調整弁127の開度と、吸引ポンプ121及びカスケードポンプ123の流体の吐出流量又は吐出圧力を調節することにより、バブル水タンク2へ導かれるウルトラファインバブルの粒径と濃度を調節することができる。
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.
また、このバブル水製造装置103は、バブル水タンク2の水のウルトラファインバブルの濃度を測定し、この測定値に基づいて、吸引ポンプ121及びカスケードポンプ123の吐出量と、混合エア量調整弁127の開度を調節して、バブル水タンク2のウルトラファインバブルの濃度を調節することができる。
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.
上記バブル水製造装置103は、第2の制御装置を設け、この第2の制御装置により、上記混合エア量調整弁127の開度と、吸引ポンプ121及びカスケードポンプ123による流体の吐出流量又は吐出圧力を制御して、バブル水タンク2のウルトラファインバブルの粒径と濃度を調節してもよい。
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.
例えば、バブル水タンク2の流体に含まれる気泡の径を小さくするためには、混合エア量調整弁127の開度を下げてエジェクタ122への空気の供給量を低減し、吸引ポンプ121及びカスケードポンプ123の運転を継続する。バブル水タンク2の流体が、吸引ポンプ121で吸引されてウルトラファインバブル製造器26に導かれ、含有する気泡が微細化されてカスケードポンプ123に吸引され、バブル水タンク2に戻される。バブル水タンク2の流体を、吸引ポンプ121、ウルトラファインバブル製造器26及びカスケードポンプ123に循環させることにより、この流体に含まれる気泡の径を効果的に小さくすることができる。
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.
また、例えば、バブル水タンク2の流体に含まれる気泡の濃度を増加させるためには、混合エア量調整弁127の開度を上げてエジェクタ122への空気の供給量を増やし、吸引ポンプ121及びカスケードポンプ123の運転を継続する。バブル水タンク2の流体が、吸引ポンプ121で吸引されて一部がエジェクタ122に導かれて空気が添加される。また、他の部分は吸引ポンプ121からウルトラファインバブル製造器26に導かれる。流体の気泡がウルトラファインバブル製造器26で微細化され、カスケードポンプ123に吸引されて、バブル水タンク2に戻される。バブル水タンク2の流体を、吸引ポンプ121、エジェクタ122、ウルトラファインバブル製造器26及びカスケードポンプ123に循環させることにより、この流体に含まれる気泡の濃度を効果的に増大させることができる。
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.
上記バブル水製造装置103のウルトラファインバブル製造器26には、上流側と下流側の間、すなわち、供給管41の流体の圧力と排出管42の流体の圧力との間に、4MPa以上6MPa以下の圧力差が生じるように、吸引ポンプ121の吐出量とカスケードポンプ123の吸入量を調節するのが好ましい。この場合、供給管41における流体の圧力を、排出管42における流体の圧力よりも高く調節する。このように、ウルトラファインバブル製造器26の上流側と下流側の間に、4MPa以上6MPa以下の圧力差を生じさせることにより、ウルトラファインバブル製造器26により安定してウルトラファインバブルを含有する水を製造することができる。
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.
このようにして、変形例のバブル水製造装置103により、安定して50~70nmのウルトラファインバブルを形成することができる。また、このバブル水製造装置103は、空気以外に、酸素や水素のウルトラファインバブルを含有する水を製造してもよい。酸素や水素のウルトラファインバブルを含有する水を製造する場合、水に添加されなかった余剰の酸素や水素を、気液分離器125で分離して、気体タンク124に戻すことにより、酸素や水素がバブル水製造装置103の外部に漏洩する不都合を防止できる。したがって、酸素や水素のウルトラファインバブルを含有する水を製造する場合に、酸素や水素の漏洩に起因する火災などの不都合を効果的に防止できる。
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.

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.
また、上記実施形態において、食用豚に、空気のウルトラファインバブルを含有する水を給与したが、空気以外に、水素や酸素等の他の気体のウルトラファインバブルを含有する水を給与してもよい。また、水以外に、微酸性電解水や、その他の各種の成分を含有する水にウルトラファインバブルを含有させた飲用水を給与してもよい。水素のウルトラファインバブルを含有する水を用いた場合と、酸素のウルトラファインバブルを含有する水を用いた場合においても、食用豚の成長を促進できる効果や、豚の飼料の消費量の低減効果が確認された。また、微酸性電解水を用いた場合においても、食用豚の成長を促進できる効果が確認された。
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.

(試験1)
試験1では、肥育を行う肥育豚舎に試験区と対照区を設け、各区で体重が約75kgの肥育後期の食用豚を3頭ずつ肥育した。各区で肥育した3頭は、いずれも雄が1頭であり、雌が2頭である。試験区ではウルトラファインバブル水を自由飲水させ、対照区では山梨県の水道水を自由引水させた。試験区と対照区のいずれも、同一の市販の肥育用配合飼料を給与した。試験区と対照区で体重が概ね110kgに達した食用豚について、発育速度、肉質及び枝肉成績等の分析を行った。次の表1は、肥育の開始時の体重と、肥育期間の終了時の体重と、肥育期間による1日平均増体重と、肥育日数と、飼料要求率である。いずれも、1頭当たりの平均値である。表2は、試験区及び対照区で肥育した食用豚から得られた枝肉の計測結果である。表3乃至5は、試験区及び対照区で肥育した食用豚から得られたロース肉の肉質の分析結果である。
(Test 1)
In Test 1, a test plot and a control plot were provided in a fattening pig pen for fattening, and in each plot, three dietary pigs in a late fattening stage having a body weight of about 75 kg were fattened. Of the three fattened animals in each ward, one male and two females were used. Ultra fine bubble water was freely drunk in the test section, and tap water of Yamanashi prefecture was freely drawn in the control section. The same commercially available compounded feed for fattening was fed to both the test plot and the control plot. With respect to the edible pigs having a body weight of approximately 110 kg in the test section and the control section, analysis of growth rate, meat quality, carcass performance and the like was performed. The following Table 1 shows the weight at the start of fattening, the weight at the end of the fattening period, the average daily weight gain due to the fattening period, the number of fattening days, and the feed conversion rate. All are average values per head. Table 2 shows the measurement results of carcasses obtained from the edible pigs fattened in the test section and the control section. Tables 3 to 5 show the analysis results of the meat quality of the loin meat obtained from the edible pigs fattened in the test section and the control section.

In Test 1, a test plot and a control plot were provided in a fattening pig pen for fattening, and in each plot, three dietary pigs in a late fattening stage having a body weight of about 75 kg were fattened. Of the three fattened animals in each ward, one male and two females were used. Ultra fine bubble water was freely drunk in the test section, and tap water of Yamanashi prefecture was freely drawn in the control section. The same commercially available compounded feed for fattening was fed to both the test plot and the control plot. With respect to the edible pigs having a body weight of approximately 110 kg in the test section and the control section, analysis of growth rate, meat quality, carcass performance and the like was performed. The following Table 1 shows the weight at the start of fattening, the weight at the end of the fattening period, the average daily weight gain due to the fattening period, the number of fattening days, and the feed conversion rate. All are average values per head. Table 2 shows the measurement results of carcasses obtained from the edible pigs fattened in the test section and the control section. Tables 3 to 5 show the analysis results of the meat quality of the loin meat obtained from the edible pigs fattened in the test section and the control section.
表1から分かるように、発育速度については、肥育開始から出荷到達までの1日平均増体重が試験区で有意に高く、肥育日数は対照区と比較して5日短縮された。また、試験期間中の飼料摂取量は、対照区の平均で124kg/頭である一方、試験区の平均で111.5kg/頭であった。その結果、試験区は、対照区よりも12.5kg/頭の飼料の削減を行うことができた。なお、飼料摂取量は、終了体重と開始体重との差に飼料要求率を乗じて求められる。
As can be seen from Table 1, 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 plot, and the number of fattening days was shortened by 5 days compared to the control plot. The feed intake during the test period was 124 kg/head on average in the control group, while it was 111.5 kg/head in average in the test group. As a result, the test plot was able to reduce the feed by 12.5 kg/head compared to the control plot. The feed intake is obtained by multiplying the difference between the end weight and the start weight by the feed requirement rate.
枝肉の計測結果については、表2から分かるように、試験区と対照区の間で有意な差は見られなかった。ロース肉の肉質については、表3から分かるように、試験区は、筋肉内脂肪含量が対照区よりも多く、ドリップロスが対照区よりも少なかった。また、表4から分かるように、試験区は、破断強度が対照区よりも小さかった。以上より、ウルトラファインバブル水の給与により、ドリップロスの少なく、霜降りの柔らかいロース肉が得られるといえる。
Regarding carcass measurement results, as can be seen from Table 2, no significant difference was observed between the test plot and the control plot. Regarding the meat quality of the loin meat, as can be seen from Table 3, the test group had more intramuscular fat content than the control group and less drip loss than the control group. Further, as can be seen from Table 4, the breaking strength of the test section was smaller than that of the control section. From the above, it can be said that by feeding ultra fine bubble water, soft roasted meat with less drip loss can be obtained.
また、表5から分かるように、酸化しやすく悪臭の原因になりやすいリノール酸やリノレン酸等の多価不飽和脂肪酸は、試験区が対照区よりも少ない。一方、パルミチン酸やステアリン酸等の飽和脂肪酸と、パルミトレイン酸やオレイン酸等の一価不飽和脂肪酸は、試験区が対照区よりも多い。したがって、悪臭が少なく、LDLコレステロールを低下でき、舌触りの良い豚肉が得られるといえる。
Also, as can be seen from Table 5, the amount of polyunsaturated fatty acids such as linoleic acid and linolenic acid, which are easy to oxidize and cause bad odor, is less in the test section than in the control section. On the other hand, the amount of saturated fatty acids such as palmitic acid and stearic acid and the amount of monounsaturated fatty acids such as palmitoleic acid and oleic acid are greater in the test section than in the control section. Therefore, it can be said that pork with less bad odor, lower LDL cholesterol and good texture can be obtained.
(試験2)
試験2では、肥育を行う肥育豚舎に3つの試験区と1つの対照区を設け、各区で体重が約35kgの肥育前期の食用豚を4頭ずつ肥育した。各区で肥育した4頭は、いずれも雄が2頭であり、雌が2頭である。試験区1ではウルトラファインバブル水を自由飲水させ、試験区2では植物抽出物混合発酵液の水溶液を自由飲水させ、試験区3ではウルトラファインバブル水と植物抽出物混合発酵液の水溶液の混合液を自由飲水させた。対照区では山梨県の水道水を自由引水させた。植物抽出物混合発酵液の水溶液は、株式会社T.Sエコファーム社製のT.Sミネターゼを、500倍の水道水で希釈して作製した。試験区と対照区のいずれも、同一の市販の肥育用配合飼料を給与した。試験区と対照区で体重が概ね110kgに達した食用豚について、発育速度、肉質及び枝肉成績等の分析を行った。試験区1は、図1の第1飼育エリアA1に設定でき、試験区2は第3飼育エリアA3に設定でき、試験区3は第2飼育エリアA2に設定でき、対照区は第4飼育エリアA4に設定できる。 (Test 2)
InTest 2, three test plots and one control plot were provided in a fattening pig pen for fattening, and in each of the plots, four dietary pigs with a body weight of about 35 kg in the early fattening period were fed. Of the 4 fattened animals in each ward, there were 2 males and 2 females. In test section 1, ultrafine bubble water was freely drinkable, in test section 2, an aqueous solution of plant extract mixed fermented solution was allowed to freely drink, and in test section 3, a mixture of ultrafine bubble water and an aqueous solution of plant extract mixed fermented solution. Was allowed to drink water freely. In the control area, tap water from Yamanashi prefecture was freely drawn. An aqueous solution of a mixed extract of plant extracts is described in T. T.S. made by S Eco Farm. S-minase was prepared by diluting it with 500 times tap water. The same commercially available compounded feed for fattening was fed to both the test plot and the control plot. With respect to the edible pigs having a body weight of approximately 110 kg in the test section and the control section, analysis of growth rate, meat quality, carcass performance and the like was performed. The test plot 1 can be set to the first breeding area A1 in FIG. 1, the test plot 2 can be set to the third breeding area A3, the test plot 3 can be set to the second breeding area A2, and the control plot is the fourth breeding area. Can be set to A4.
試験2では、肥育を行う肥育豚舎に3つの試験区と1つの対照区を設け、各区で体重が約35kgの肥育前期の食用豚を4頭ずつ肥育した。各区で肥育した4頭は、いずれも雄が2頭であり、雌が2頭である。試験区1ではウルトラファインバブル水を自由飲水させ、試験区2では植物抽出物混合発酵液の水溶液を自由飲水させ、試験区3ではウルトラファインバブル水と植物抽出物混合発酵液の水溶液の混合液を自由飲水させた。対照区では山梨県の水道水を自由引水させた。植物抽出物混合発酵液の水溶液は、株式会社T.Sエコファーム社製のT.Sミネターゼを、500倍の水道水で希釈して作製した。試験区と対照区のいずれも、同一の市販の肥育用配合飼料を給与した。試験区と対照区で体重が概ね110kgに達した食用豚について、発育速度、肉質及び枝肉成績等の分析を行った。試験区1は、図1の第1飼育エリアA1に設定でき、試験区2は第3飼育エリアA3に設定でき、試験区3は第2飼育エリアA2に設定でき、対照区は第4飼育エリアA4に設定できる。 (Test 2)

次の表6は、肥育前期の開始時の体重と、肥育後期の開始時の体重と、肥育後期の終了時の体重と、全肥育期間による1日平均増体重と、肥育日数である。いずれも、1頭当たりの平均値である。表7は、肥育前期と肥育後期における1日平均増体重と、飼料要求率であり、いずれも1頭当たりの平均値である。表8は、試験区及び対照区で肥育した食用豚から得られた枝肉の計測結果である。表9及び10は、試験区及び対照区で肥育した食用豚から得られたロース肉の肉質の分析結果である。
The following Table 6 shows the weight at the beginning of the early fattening period, the weight at the beginning of the late fattening period, the weight at the end of the late fattening period, the average daily weight increase due to the entire fattening period, and the number of fattening days. 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.
表6から分かるように、発育速度については、肥育開始から出荷到達までの1日平均増体重が試験区1乃至3で有意に高く、肥育日数は対照区と比較して最大で11日短縮された。また、試験期間中の飼料摂取量は、対照区の平均で381.7kg/頭である一方、試験区1の平均で320.1kg/頭、試験区2の平均で310.2kg/頭、試験区3の平均で389.4kg/頭である。その結果、試験区1で61.6kg/頭の飼料を削減でき、試験区2で71.5kg/頭の飼料を削減できる。
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.
枝肉の計測結果については、表8から分かるように、試験区2において、ロース断面積が対照区よりも大きい。他の計測結果については、試験区と対照区の間で有意な差は見られなかった。ロース肉の肉質については、表9から分かるように、試験区3は、ドリップロスが対照区よりも少なく、筋肉内脂肪含量が対照区よりも多い。また、表10から分かるように、試験区1は、伸展率が対照区よりも大きかった。以上より、ウルトラファインバブル水の給与により、ドリップロスの少なく、霜降りの柔らかいロース肉が得られるといえる。
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. Further, as can be seen from Table 10, the test section 1 had a greater extension rate than the control section. From the above, it can be said that by feeding ultra fine bubble water, soft roasted meat with less drip loss can be obtained.
また、表5から分かるように、酸化しやすく悪臭の原因になりやすいリノール酸やリノレン酸等の多価不飽和脂肪酸は、試験区が対照区よりも少ない。一方、パルミチン酸やステアリン酸等の飽和脂肪酸と、パルミトレイン酸やオレイン酸等の一価不飽和脂肪酸は、試験区が対照区よりも多い。したがって、悪臭が少なく、LDLコレステロールを低下でき、舌触りの良い豚肉が得られるといえる。
Also, as can be seen from Table 5, the amount of polyunsaturated fatty acids such as linoleic acid and linolenic acid, which are easy to oxidize and cause bad odor, is less in the test section than in the control section. On the other hand, the amount of saturated fatty acids such as palmitic acid and stearic acid and the amount of monounsaturated fatty acids such as palmitoleic acid and oleic acid are greater in the test section than in the control section. Therefore, it can be said that pork with less bad odor, lower LDL cholesterol and good texture can be obtained.
