本発明は、牛のひづめ障害予防用の洗足剤及びその使用方法とその製造方法に係り、より詳細には、牛ひづめ用洗足器の洗足液の原料として使われる洗足剤であって、洗浄機能と消毒機能を兼備した牛のひづめ障害予防用の洗足剤及びその使用方法とその製造方法に関する。 The present invention relates to a foot washing agent for preventing hooves disorder of cattle, a method for using the same and a method for producing the same, and more particularly, a foot wash used as a raw material for a foot washing solution for a cow hooves basin, The present invention relates to a foot washing agent for preventing cattle hoofs having both a washing function and a disinfecting function, a method for using the same, and a method for producing the same.
一般に、韓牛や乳牛などのようにひづめの割れた家畜のひづめの間には、家畜に有害なバクテリアなどが繁殖し、ひづめに大きな障害が生じることができる。
なお、韓牛と乳牛は、身体が大きいために足に体重が多く集まり、一日の大部分の時間を立って生活する牛にとって、ひづめの障害はそのまま生存に直結するという恐れがあった。
したがって、韓牛と乳牛を飼育する農家では、ひづめの疾病を予防する方法がない場合には、ひづめ障害の発生時に、抗生軟膏を患部に塗布して包帯で包んだり、硫酸銅液を患部にスプレイしたりする方法を取ってきた。なお、硫酸銅液やホルマリンのような物質を、洗足器や洗足場で洗足液として使用する方法も採用してきた。
In general, bacteria that are harmful to livestock breed between hooves of hooves that have broken hooves, such as Korean beef and dairy cattle.
Korean cows and dairy cows were large in weight and gathered a lot of weight on their feet, and there was a risk that hooves' obstacles would directly lead to survival for cows who lived most of the day.
Therefore, if there is no way to prevent hooves disease, farmers who raise Korean beef and dairy cows should apply antibiotic ointment to the affected area and wrap the affected area with copper sulfate solution when an hooves disorder occurs. I've taken a way to spray. In addition, the method of using substances, such as a copper sulfate solution and formalin, as a foot washing liquid in a basin or a basin has been adopted.
しかしながら、上記のような従来の消毒によるひづめの消毒方法では、韓牛や乳牛の割れたひづめの間から汚染物質がすっきり除去されないことから、消毒液が目的部位によく浸透されず、充分な消毒効果が得られないという問題点があった。
本発明は上記の問題点を解決するためのもので、その目的は、牛のひづめの洗浄と消毒効果が同時に得られるようにし、牛のひづめの汚染部位が清潔に洗浄された状態で消毒されるようにすることによって、牛のひづめ障害の予防を通じて、産乳量及び繁殖率などの生産性の低下を未然に防止し、かつ、淘汰のような極端な状況を避けることができる他、牛の健康と快適性の向上にも大きく寄与できるようにした牛のひづめ障害予防用の洗足剤及びその使用方法とその製造方法を提供することにある。
However, in the conventional sterilization method of hooves by disinfection as described above, since the contaminants are not removed cleanly between the broken hooves of Korean beef and dairy cows, the disinfectant solution does not penetrate well to the target site, and the sterilization is sufficiently performed. There was a problem that the effect could not be obtained.
The present invention is intended to solve the above-mentioned problems, and its purpose is to obtain a cow hooves cleaning and disinfecting effect at the same time, and to disinfect the cow hooves in a clean state. By doing so, it is possible to prevent decline in productivity such as milk production and reproductive rate through prevention of cattle hoof disorders, and avoid extreme situations such as drought, It is an object of the present invention to provide a foot washing agent for preventing hooves disorder in cows, a method for using the same, and a method for producing the same, which can greatly contribute to the improvement of cow health and comfort.

In addition, the foot wash is used as a foot wash for a cow hoof wash in a state of being diluted with water, and the concentration of the foot wash in this foot wash is preferably 5% to 16% by weight. .
Moreover, the manufacturing method of the foot wash for the cattle hoof disorder based on this invention is 15-25 weight% of stannic acid, 15-25 weight% of citric acid, 15-25 weight% of zinc sulfate, sodium molybdate 15-15 A process of mixing each solid content of 25% by weight and 15-25% by weight of potassium nitrate; a process of producing a cleaning liquid by liquefying the mixture and water by mixing 50% by weight; and sodium hypochlorite A step of preparing a stock solution; and a step of mixing 50% by weight of each of the cleaning solution and the sodium hypochlorite stock solution.
本発明による牛のひづめ障害予防用の洗足剤は、洗浄液成分と消毒成分を同時に含む。したがって、このような洗足剤を水に希釈して洗足器に使われる洗足液とした状態で、この洗足器を介して牛のひづめを洗浄すると、まず、洗足液に入っている洗浄液成分によって牛のひづめの間についていた異物が除去されながら牛のひづめについていた細菌が洗足液に完全に晒され、この状態では、洗足液中の次亜塩素酸ソーダによって牛のひづめについていた細菌がきれいに消毒されることができる。したがって、本発明による洗足剤によって作られた洗足液を使用すると、牛のひづめ障害が效果的に予防及び治療され、産乳量及び繁殖率などの生産性の低下を未然に防止し、且つ、淘汰のような極端な状況を避けることができる他、牛の健康と快適性の向上にも大きく寄与することが可能になる。 The foot wash for preventing cattle hoof injury according to the present invention includes a cleaning liquid component and a disinfecting component at the same time. Therefore, when the hooves of a cow are washed through this foot wash in a state where such a foot wash is diluted in water to form a foot wash used in a foot wash, first, the washing liquid components contained in the foot wash are used. The bacteria that were attached to the cow's hooves were completely exposed to the foot washing solution while the foreign matter that was placed between the cow's hooves was removed. Can be disinfected cleanly. Therefore, when the foot washing solution made by the foot washing agent according to the present invention is used, cattle hoof disorders are effectively prevented and treated, and a decrease in productivity such as milk production and reproductive rate is prevented, and In addition to being able to avoid extreme situations such as drought, it is also possible to make a significant contribution to improving the health and comfort of cattle.
以下、本発明の好適な実施例について詳細に説明する。
本発明による洗足剤は、水に希釈された状態で牛ひづめ用の洗足器に使われる洗足液を形成する原料で、スズ酸１５〜２５重量％とクエン酸１５〜２５重量％と硫酸亜鉛１５〜２５重量％とモリブデン酸ソーダ１５〜２５重量％と硝酸カリウム１５〜２５重量％の各固形分と水とを混合して用意する洗浄液と、次亜塩素酸ソーダ原液とを混合して製造する。
なお、このような洗足剤は、スズ酸１５〜２５重量％、クエン酸１５〜２５重量％、硫酸亜鉛１５〜２５重量％、モリブデン酸ソーダ１５〜２５重量％、硝酸カリウム１５〜２５重量％の各固形分を混合する過程と、このようにして混合された混合物と水とをそれぞれ５０重量％ずつ混合しながら液状化して洗浄液を製造する過程と、この洗浄液と次亜塩素酸ソーダ原液とをそれぞれ５０重量％ずつ混合する過程と、を含んで製造される。
Hereinafter, preferred embodiments of the present invention will be described in detail.
The foot wash according to the present invention is a raw material for forming a foot wash used in a beef hog washing machine in a state diluted with water. 15 to 25% by weight of stannic acid, 15 to 25% by weight of citric acid and zinc sulfate. A cleaning liquid prepared by mixing 15 to 25% by weight, sodium molybdate 15 to 25% by weight and potassium nitrate 15 to 25% by weight and water, and a sodium hypochlorite stock solution are mixed to produce. .
In addition, such a foot washing agent is 15-25% by weight of stannic acid, 15-25% by weight of citric acid, 15-25% by weight of zinc sulfate, 15-25% by weight of sodium molybdate, and 15-25% by weight of potassium nitrate. A process of mixing the solid content, a process of producing a cleaning liquid by liquefying the mixture thus mixed and water by 50% by weight, respectively, and this cleaning liquid and sodium hypochlorite stock solution, respectively And 50% by weight of mixing.
なお、このようにして製造された洗足剤を用いて洗足液を作る時には、この洗足剤を再び水に混合し、洗足剤の濃度が５重量％〜１６重量％の洗足液とすることが好ましい（これは、後述する実験値で証明する。）が、このように製造された洗足液を洗足器に入れた状態でこの洗足器を牛が通過すると、洗足器を通過する過程で牛のひづめが洗足液に浸され、洗浄液の洗浄作用と次亜塩素酸ソーダ原液の消毒作用によって牛のひづめに繁殖した細菌がきれいに除去されることができる。
すなわち、この洗浄液を構成する成分のうち、スズ酸、クエン酸及び硫酸亜鉛は、優れた洗浄力を発揮する物質で、これらスズ酸とクエン酸と硫酸亜鉛との混合物によって、牛が洗足器を通過する短い時間内で、ひづめについていた異物及び汚染物質が除去されるわけである。ここで、モリブデン酸ソーダと硝酸カリウムは、スズ酸とクエン酸と硫酸亜鉛とが混合される過程で各物質本来の洗浄力が低下するのを防止する役割を果たす。
In addition, when making a foot wash using the foot wash produced in this way, it is preferable to mix this foot wash with water again to obtain a foot wash with a concentration of 5 to 16% by weight of the foot wash. (This is proved by the experimental values described later.) However, when a cow passes through this foot wash with the foot wash thus prepared in the foot wash, The shark is soaked in the rinsing solution, and the bacteria propagated in the hooves of the cow can be removed cleanly by the cleaning action of the washing liquid and the disinfecting action of the sodium hypochlorite stock solution.
That is, stannic acid, citric acid and zinc sulfate among the components constituting this washing liquid are substances that exhibit excellent detergency, and the mixture of these stannic acid, citric acid and zinc sulfate allows the cow to use the basin. Within a short time to pass, the trashed foreign matter and contaminants are removed. Here, sodium molybdate and potassium nitrate play a role of preventing the detergency of each substance from deteriorating in the process of mixing stannic acid, citric acid and zinc sulfate.
このような洗浄液の成分によって異物が除去されると、牛のひづめについていた細菌は洗足液に完全に晒された状態となり、この状態では、洗足液中の次亜塩素酸ソーダによって牛のひづめについていた細菌はきれいに消毒されることができる。この事実は、下記のような多くの臨床試験から明らかにされた。
次に、洗足液の殺菌効果試験の結果について説明する。下記の表１は、分離した細菌に対する洗足剤のＭＩＣとＭＢＣを示す。
When foreign substances are removed by the components of the washing liquid, the bacteria that were attached to the cow's hoof are completely exposed to the foot washing solution. In this state, the cow's hoof is washed by sodium hypochlorite in the washing solution. Stuffed bacteria can be disinfected cleanly. This fact has been revealed from a number of clinical trials such as:
Next, the result of the bactericidal effect test of the foot washing solution will be described. Table 1 below shows the MIC and MBC of the foot wash against the isolated bacteria.
すなわち、透明なガラスのｂｒｏｔｈ培養管にｍｕｌｌｅｒ−ｈｉｎｔｏｎ ｂｒｏｔｈを用いて試製品及び硫酸銅の濃度を５．００、２．５０、１．２５、０．６３、０．３１、０．１５、０．０８％に希釈し、ＭＩＣ(Ｍｉｎｉｍａｌ Ｉｎｈｉｂｉｔｉｏｎ Ｃｏｎｃｅｎｔｒａｔｉｏｎ、最小発育阻止濃度)及びＭＢＣ（Ｍｉｎｉｍａｌ Ｂａｃｔｅｒｉｃｉｄａｌ Ｃｏｎｃｅｎｔｒａｔｉｏｎ、最小殺滅濃度）値を求めた結果、硫酸銅液のＭＩＣとＭＢＣは細菌ＡとＢに対してそれぞれ０．３１％と表れた。これに対し、洗足液は、細菌Ａ（Ｅ．ｃｏｌｉ）に対してはＭＢＣが５％と表れた。洗足液は、硫酸銅に比べて、ＭＢＣが高く表れたが、５％以上の濃度では、ひづめから分離される大部分の細菌に対して死滅効果を示すものと判断された。
下記の表２は、細菌Ａ（Ｅ．ｃｏｌｉ）の洗足液に対するＭＩＣ及びＭＢＣを示す。
That is, using a muller-hinton broth in a transparent glass broth culture tube, the concentrations of the test product and copper sulfate were 5.00, 2.50, 1.25, 0.63, 0.31, 0.15, 0. After dilution to 0.08%, MIC (Minimum Inhibition Concentration, minimum inhibitory concentration) and MBC (Minimum Bacterial Concentration, minimum killing concentration) values were determined. And 0.31% respectively. In contrast, the foot wash showed 5% MBC against bacteria A (E. coli). The foot washing liquid showed higher MBC than copper sulfate, but at a concentration of 5% or more, it was judged that the washing liquid showed a killing effect on most bacteria separated from the hooves.
Table 2 below shows the MIC and MBC for the foot wash of bacteria A (E. coli).
ここでも、濃度は５．００、２．５０、１．２５、０．６３、０．３１、０．１５、０．０８％とした。
洗足液のＥ．ｃｏｌｉに対するＭＩＣ及びＭＢＣを測定した結果、表２に示すように、１．２５％及び５％とそれぞれ表れた。牛のひづめから分離された細菌Ａ（Ｅ．ｃｏｌｉ）と同様に、牛舎の床から良く分離されるＥ．ｃｏｌｉへの消毒効果も充分なものと判断されたし、別に図示してはいないが、Ｂａｃｉｌｌｕｓに対しても略同様な結果が得られた。
本発明による洗足液の細菌減少率を調べた結果を、下写真に示す。
Again, the concentrations were 5.00, 2.50, 1.25, 0.63, 0.31, 0.15, 0.08%.
E. Washing solution As a result of measuring MIC and MBC for E. coli, 1.25% and 5% appeared as shown in Table 2. Similar to bacteria A (E. coli) isolated from cow hooves, E. coli is well isolated from the barn floor. It was judged that the disinfection effect on E. coli was also sufficient, and although not shown separately, substantially the same result was obtained for Bacillus.
The results of examining the bacteria reduction rate of the foot wash according to the present invention are shown in the photograph below.
