2. Description of the Related Art In the human society, various animals are generally bred. In the field of livestock, a large amount of livestock and poultry are bred in large-scale barns.

[0004] For example, in the field of poultry raising, a large amount of chickens are bred in a huge poultry house, and a large amount of eggs or broilers are produced daily. In order to establish such a poultry farming industry, it is essential to prevent chicken disease as much as possible and to raise the breeding yield. To this end, it is necessary to maintain good hygiene conditions in the poultry house, and it is said that if the sanitary management of the poultry house is not properly carried out, it may cause a collective disease.

In general, various infectious diseases are known in poultry farming. For example, as viral infectious diseases, Newcastle disease, infectious bronchitis, chicken encephalomyelitis and the like are known. In such a viral infection,
Infected chickens excrete feces containing the virus, which splash and infect other chickens by direct contact or via feed or drinking water. Thus, poor poultry house hygiene increases the probability of an outbreak of infectious disease. In addition, the same applies to bacterial infections, mold infections, protozoal infections, and the like.

In order to maintain the inside of the poultry house clean, it is necessary to periodically clean the inside of the poultry house and wash away the poultry manure. It is necessary to thoroughly clean and / or disinfect breeding items such as bowls, feeders, waterers, cages and the like. In addition, drinking water,
Usually, it is placed in a poultry house in a water supply device, but it is desirable to frequently change drinking water in order to prevent the spread of viruses, bacteria, and the like. As described above, a large amount of water is consumed to maintain the hygiene of the poultry house.

For terrestrial animals other than chickens, for example, in raising experimental animals, drinking water is obtained by sterilizing and removing tap water with ultraviolet rays, a sterilizing filter, sodium hypochlorite, etc. Paying is being done.

Recently, pollution issues have become a topic of social concern, and in terrestrial animal breeding houses, livestock odor, manure odor,
It is necessary to pay close attention to sewage, etc., which may cause inconveniences in the neighborhood.
996).

[0009] As described above, in general, breeding terrestrial animals requires a large amount of water for washing and disinfection besides drinking water. It is consumed mainly for disease prevention.

On the other hand, in recent years, it has been known that electrolyzed water obtained by electrolyzing various solutions has a bactericidal effect, and it is urgent to establish an application technique of such electrolyzed water (Shikiko Shiba) Authors, Handbook of Strong Electrolysis Water, Medical Information Company, 1995).

Conventional electrolyzed water is disclosed in, for example,
No. 0293 (hereinafter referred to as prior art 1). In this technique, water to which sodium chloride is added is passed through an electrolytic cell with a diaphragm, which is electrolyzed to obtain strongly acidic water generated on the cathode side as electrolytic water. Is not less than 1.5 and not more than 3.2, and is said to have a higher bactericidal effect than a simple low pH solution.

Further, electrolyzed water produced by the technique disclosed in Japanese Patent No. 2627100 (hereinafter referred to as prior art 2) is obtained by mixing water containing sodium chloride and water containing hydrochloric acid, This is obtained by electrolysis in a non-diaphragm electrolytic cell, and the water to which sodium chloride is added is an indispensable additive for increasing the electrolysis efficiency at the time of electrolysis.

These electrolyzed waters have a higher sterilizing effect even at a low chlorine concentration as compared with sterilized water prepared by dissolving sodium hypochlorite in water. In general, there is no need to make fine density adjustments each time it is used.
It is particularly suitable in the field of animal husbandry.

[0014]

However, since the prior art 1 is a method using a diaphragm electrolyzer, the treatment capacity is low, and particularly, water for washing or disinfecting terrestrial animals, water in a terrestrial animal breeding house, etc. The capacity tends to be insufficient for applications that consume large amounts of electrolyzed water, such as water for washing or disinfecting, water for washing or disinfecting terrestrial animal breeding products, or deodorizing water.

The electrolyzed water produced according to the prior art 1 is a strongly acidic water having a pH of 1.5 to 3.2,
Further, the electrolyzed water produced according to the prior arts 1 and 2 is:
Since both contain large amounts of salt, any electrolytic water has the property of corroding metals, and when used in terrestrial animal breeding houses with many metal instruments, individual instruments are easily corroded. However, there is a problem that long-term use is not desirable.

Further, in particular, since the electrolyzed water produced according to the prior arts 1 and 2 contains salt, there is a problem that the salt is precipitated as a solid after use. That is, there has been a problem that it is difficult to clean and remove the salt crystals precipitated by spraying the electrolytic water and then drying.

Furthermore, the electrolyzed water produced by the above-described prior arts 1 and 2 is either unsuitable as a terrestrial animal drinking water because it is either strongly acidic or contains salt.

After all, the conventional electrolyzed water has many problems as terrestrial animal breeding water.

It is an object of the present invention to add no sodium,
It is a terrestrial animal breeding water consisting of electrolyzed water having a nearly neutral pH, which can be used for a long time without corroding metal equipment, does not precipitate salt, and is suitable for drinking. It is an object of the present invention to provide terrestrial animal breeding water which is useful for maintaining the health of terrestrial animals and preventing diseases as a whole, and which can be easily produced in large quantities at low cost.

[0020]

Means for Solving the Problems The present invention for solving the above-mentioned problems is directed to a terrestrial animal breeding water comprising electrolytic water having a sodium ion concentration of 200 ppm or less and a pH in the range of 4.5 to 6.8. It is.

In the present invention, the electrolytic water is obtained by adding hydrochloric acid to water containing no sodium chloride, passing the hydrochloric acid-added water through a non-diaphragm electrolytic cell, and electrolyzing the passed hydrochloric acid-added water. The obtained electrolysate is diluted with water and manufactured, and the terrestrial animal breeding water is terrestrial animal drinking water,
Desirable embodiments are water for washing or disinfecting terrestrial animals, water for washing or disinfecting terrestrial animal breeding houses, water for washing or disinfecting terrestrial animal breeding supplies, or deodorizing water.

Next, the present invention will be described in detail.

[0023]

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the above prior art 1 or 2.
And different electrolyzed water. That is, one feature of the terrestrial animal breeding water of the present invention is that it comprises electrolyzed water having a sodium ion concentration of 200 ppm or less, more preferably 10 ppm or less, which is a standard for water quality of general clean water.

Conventional electrolyzed water is obtained by electrolyzing water, but it has been common knowledge to add sodium chloride to increase electrolysis efficiency. That is, the idea of using electrolyzed water having a sodium ion concentration of 200 ppm or less as breeding water for terrestrial animals has not been known so far.

The terrestrial animal breeding water of the present invention is p
Another feature is that it is composed of near neutral electrolytic water having an H value of 4.5 to 6.8.

Therefore, the terrestrial animal breeding water of the present invention comprises:
There is little corrosion of metal like the electrolyzed water of the prior art 1 or 2. In addition, since the salt concentration is low and the pH is around neutral, it is suitable for drinking, and even when stored in a water supply as drinking water, it is difficult for bacteria to grow due to its bactericidal action. Therefore, there is no need to replace the battery for a long time, and the work can be reduced.

Since the terrestrial animal breeding water of the present invention is electrolyzed water to which sodium chloride is not added, even if it is used as sterilizing water and washing water, even if it evaporates, salt does not precipitate. Therefore, for example, there is no need to perform water washing after spraying the electrolyzed water, and the amount of work is reduced. Further, in general, terrestrial animals do not sweat, so excessive intake of salt is not preferred, but the breeding water of the present invention without added salt is naturally used as drinking water, and is used in terrestrial animal premises. It is suitable for any kind of breeding water.

Such electrolyzed water is desirably produced by the following procedure.

That is, first, hydrochloric acid is added to water containing no sodium chloride, and the hydrochloric acid added water is adjusted. Here, "water" refers to tap water, groundwater, underground water, demineralized water, distilled water, purified water (RO water, membrane-treated water), a mixed water thereof, or the like, which does not substantially contain sodium chloride. Means something. “Does not contain sodium chloride” means that sodium chloride is not artificially added. In the present invention, it is desirable not to add not only sodium chloride but also alkali metal chloride as a whole, and electrolyzed water having a concept of limiting the concentration of alkali metal ions may be used.

The hydrochloric acid-added water is passed through a non-diaphragm electrolytic cell and electrolyzed to obtain an electrolysate. Since it is a non-diaphragm electrolytic cell, cathodic water and anodic water are not separated after electrolysis, and can be collectively obtained as an electrolysate. Therefore, since mass production is possible, running costs can be kept low.

Naturally, no sodium chloride was added to the electrolyzed product. In other words, the sodium ion concentration exceeded the sodium ion concentration contained in the "water". There is no. That is,
The sodium ion concentration becomes 200 ppm or less.

The above operation is carried out, for example, using a commercially available electrolyzed water producing apparatus, Purestar (trademark, manufactured by Morinaga Engineering Co., Ltd.) at a concentration of 21% (weight; hereinafter the same unless otherwise specified) or a concentration of 3%. It can be performed by installing a tank storing hydrochloric acid, supplying hydrochloric acid and tap water, and performing continuous electrolysis.

The obtained electrolyzed product was diluted to pH 4.
Adjust to a range of 5 to 6.8 electrolyzed water. The electrolyzed water thus obtained is substantially free of sodium chloride and has a pH near neutrality, and is more natural than the electrolyzed water according to the above-mentioned prior art 1 or 2. It has physical properties close to water.

The terrestrial animal breeding water of the present invention as described above is not only terrestrial animal drinking water, but also terrestrial animal body washing or sterilizing water, terrestrial animal breeding house cleaning or sterilizing water, terrestrial animal breeding supplies. It is desirably used as washing or sterilizing water or deodorizing water.

When used for washing, disinfecting or deodorizing the body of a terrestrial animal, the pH of the electrolyzed water is near neutral and no salt is added, so that the terrestrial animal can be safely washed, disinfected or sterilized. Can be deodorized. In this case, as a working method, various working methods such as spraying, spraying, coating, washing and dipping the terrestrial animal body can be adopted.

When used for cleaning, disinfecting, or deodorizing the inside and outside of a building where terrestrial animals are raised, the building wall,
It is desirable to discharge water to the floor, equipment, etc., and thoroughly wash out excrement.

The water for cleaning, disinfecting or deodorizing terrestrial animal breeding products is used for cleaning, disinfecting or deodorizing various instruments used for breeding terrestrial animals. In this case, the electrolytic water is used. Since the pH is near neutral and no salt is added, the metal does not corrode much and can be used safely even with a metal device.

The terrestrial animals in the present invention include, for example, livestock and poultry, and include cattle, horses, sheep, goats, pigs, rabbits,
Mink, chicken, quail, turkey, turkey, duck, etc. can be exemplified, and pets are, for example, dogs, cats, small birds, pigeons, reptiles and the like, and experimental animals are, for example, mice, rats, Guinea pigs, rabbits, frogs, etc., and various birds and beasts in zoos can also be exemplified.

Next, the present invention will be described in detail with reference to test examples. Test Example 1 This test was performed to compare the degree of metal corrosion between the electrolyzed water of the present invention and the electrolyzed water according to the prior arts 1 and 2.

1) Preparation of Sample Electrolyzed water (effective chlorine concentration: 30 ppm) produced by the same apparatus and the same method as in Example 1 described later was used as a test sample of the present invention.

Further, a batch type electrolytic cell with a diaphragm was fabricated as a trial, simulating the prior art 1, and the saline solution was electrolyzed, and the water generated on the cathode side was collected to obtain a pH of 2.1 and a salt concentration of 0.1. 05
g / l, and electrolyzed water having an effective chlorine concentration of 30 ppm were prepared. Further, a batch type non-diaphragm electrolytic cell was fabricated by simulating the prior art 2, a saline solution containing hydrochloric acid was stored therein, and electrolysis was performed to obtain a pH of 5.8, a salt concentration of 0.03 g / l, and an effective concentration of 0.03 g / l. Electrolyzed water having a chlorine concentration of 30 ppm was produced, and this was used as Control Sample 2.

2) Test method Four kinds of metal pieces (50 mm × 50 mm × 3 m) shown in Table 2
m) and prepare 3 plastic trays (53cm)
4 l each of the test sample and the control samples 1 and 2 are stored in a 3 × 44.5 cm × 6 cm depth, and half of the metal piece is exposed above the liquid level and half is immersed below the liquid level. It was fixed with clips in the form and left for 7 days. In addition, the test sample and the control samples 1 and 2 were exchanged 5 times in 7 days,
After a lapse of 7 days, each metal piece was taken out and the state of the surface was observed.

3) Test results The results of this test are as shown in Table 1. In Table 1, ◎ indicates that there was no change, ○ indicates that slight discoloration was observed, and X indicates that rust was generated and surface corrosion was apparent.

As is evident from Table 1, for aluminum, the test sample corrodes less than the control samples 1 or 2, ie, corrodes very slightly;
The test sample is a stainless steel (SUS304, SU
S316, SUS316L) at all.

As a result of this test, the terrestrial animal breeding water of the present invention has a lower degree of metal corrosion than the electrolyzed water of the prior arts 1 and 2, and is particularly frequently used in terrestrial animal breeding houses. It was found that stainless steel did not corrode at all and could be suitably used in terrestrial animal breeding houses.

The same test was carried out by changing the effective chlorine concentration and pH of the electrolyzed water, the salt concentration of the control samples 1 and 2, etc., and almost the same results were obtained.

Test Example 2 This test was conducted to confirm the effect when the terrestrial animal breeding water of the present invention was used as a terrestrial animal body washing water.

1) Preparation of Sample The same test sample as in Test Example 1 was prepared.

2) Test Method The test sample was stored in a sprayer (JF-135-100, manufactured by Iwaki Co., Ltd.) and the paw of 10 healthy 50- to 60-day-old Landrace pigs (bred in A piggery) The test sample was applied to the torso and buttocks between the
Sprayed at a flow rate of 0 l for 15 seconds each.

Before and after the treatment, the surface of the torso and buttocks of the pig was wiped 10 cm square with a sterile gauze of 5 cm × 5 cm. The wiped gauze contained sodium thiosulfate at a concentration of 0.01%. Into 10 ml of sterile saline,
This was diluted by an ordinary method, and the number of general viable cells was cultured at 35 ° C. for 48 hours using a standard agar medium (manufactured by Eiken Chemical Co., Ltd.). The number of coliforms was determined using desoxycollate medium (manufactured by Eiken Chemical Co., Ltd.). After culturing at 35 ° C. for 20 hours, the number of viable bacteria was measured by a conventional method, and the ratio of the number of remaining bacteria was calculated from the results.

The same treatment and measurement were performed with tap water for comparison.

3) Test Results The results of this test are as follows. In other words, when the test sample was sprayed, the average value of the ratio of residual bacteria for 10 pigs was 24% for general viable bacteria and 0.5% for Escherichia coli, whereas the average value was 0.5% , 64 common bacteria
% And the coliform group was 2.0%.

As a result of this test, when the terrestrial animal breeding water of the present invention was used as water for washing or disinfecting terrestrial animals, the germ removal rate was higher than that of ordinary tap water.
It has been found to be particularly effective as water for washing or disinfecting terrestrial animals.

A similar test was conducted by changing the effective chlorine concentration and pH of the electrolyzed water in various ways, and almost the same results were obtained.

Test Example 3 This test was conducted to confirm the effect of using the terrestrial animal breeding water of the present invention as terrestrial animal drinking water.

1) Preparation of Sample Electrolyzed water (effective chlorine concentration: 30 ppm) produced by the same apparatus as in Example 1 described below was diluted with tap water to adjust the pH to 6.9 and the effective chlorine concentration to 3.0 ppm. A test sample was used.

2) Test Method A water bottle containing the test sample was placed in four cages each of which was bred with three 10-week-old BALB / c mice (obtained from Japan SLC). For comparison, a water bottle containing tap water was similarly set up and left for 3 days. Three days later, the number of general viable bacteria and coliform bacteria were measured by a conventional method for the test sample and tap water in each water bottle, and the water intake of the mice was calculated from the weight difference before and after each water bottle was installed. .

3) Test Results The results of this test are as follows. In other words, coliforms were not detected in any of the test sample and tap water,
The number of general bacteria was as follows, while the test sample was not detected.
For tap water, 5.4 × for each of 2 out of 4 cages
10 ² cells / ml and 6.4 × 10 ⁵ cells / ml of viable bacteria were detected. The water intake of the test sample was 3 g on average per mouse, and the water intake of tap water was 2.8 g per mouse.

As a result of this test, when the present invention was used as drinking water, the growth of bacteria with the passage of time was smaller than that of ordinary tap water, and the amount of water intake was not different from that of tap water. It has been found that the present invention is particularly suitable as drinking water for terrestrial animals.

A similar test was conducted by changing the effective chlorine concentration and pH of the electrolyzed water in various ways, and almost the same results were obtained.

Tap water was collected from the tap water tap at a flow rate of 6.7 l / m through the water pipe. Separately from this, from a hydrochloric acid tank in which 21% concentration hydrochloric acid is stored in advance, the hydrochloric acid is supplied to a hydrochloric acid pipe at a flow rate of 1.2 ml / m by a hydrochloric acid pump.
Tap water and hydrochloric acid were mixed to continuously prepare hydrochloric acid-added water. At this time, the pH of the hydrochloric acid-added water was 0.55.

The non-diaphragm electrolytic cell was energized under the condition of 15 A, the hydrochloric acid-added water was electrolyzed, and the electrolysate was discharged from the electrolytic water pipe.

Water is flown from the dilution water pipe and merged to dilute the electrolysate and remove unnecessary hydrogen gas through a gas separator. The effective chlorine concentration is 3 ppm, the sodium ion concentration is 30 ppm, and the pH value is Water for raising terrestrial animals consisting of 6.7 electrolyzed water was obtained.

The obtained terrestrial animal breeding water was placed in a cylindrical chicken waterer, which was installed in a poultry house (owned by Company B) at a ratio of one for every 50 chickens and allowed to freely ingest as drinking water. All chickens ingested the same water as normal, and had no adverse effects on the growth of the chickens.

Example 2 An electrolysis was carried out by the same apparatus and the same method as in Example 1 except that distilled water was used as a starting material, and an electrolytic solution having a sodium ion concentration of 0 ppm and a pH value of 4.5 was obtained. Water for raising terrestrial animals consisting of water was obtained.

Example 3 Electrolyzed water obtained by the method of Example 1 was stored in a large bat, and a lower tray (made of iron coating) of a rat cage having a dirty and unpleasant odor was immersed in the bat. After the electrolyzed water was exchanged about twice, the water was sufficiently washed by hand, sterilized, and air-dried. When I approached my nose to the tray, the off-flavor was completely removed.

The surface was sterilized with a sterile gauze of 5 cm × 5 cm.
When cm was wiped off and the number of viable bacteria was measured by a conventional method, it was confirmed that the bacteria had been sufficiently sterilized.

Further, the above washing and sterilizing operation is performed every other day for one day.
After repeating 0 times, the saucer did not rust at all.
