Technical Field

The present invention relates to a livestock transport container used for storing and transporting various livestock such as cattle, horses, pigs, sheep, and birds.

The present application claims priority based on patent application No. 2019-117507, filed in japan on 25/6/2019, the contents of which are incorporated herein by reference.

Background

In the animal husbandry, measures against various infectious diseases have been taken in order to maintain the health of livestock being raised. For example, patent document 1 proposes a feed to which a photocatalytic material containing apatite having photocatalytic activity is added, a raising jig provided with the photocatalytic material, a raising facility provided with the photocatalytic material, and the like as means for suppressing invasion of pathogens such as bacteria and viruses into livestock farms and spread of infection.

In the animal husbandry, livestock may be moved between farms for breeding, or may be moved to slaughter houses for meat processing.

When the livestock is transported, a livestock transport container having a housing chamber for housing the livestock is used. For example, in patent documents 2 and 3, a livestock carrier provided with a loading platform (a livestock carrier container) for accommodating livestock is widely used.

In the case of transporting the livestock by an airplane, a ship, or the like, for example, a livestock transport container (livestock transport container) for storing the livestock is used.

Here, when livestock is delivered, it is required to reduce stress on the livestock to maintain a healthy state.

Therefore, in the livestock transport vehicle described in patent document 3, in order to keep the housing room for housing livestock clean and adjust the indoor temperature, a water spray pipe is provided at a position higher than the housed livestock, a water passage member is provided on the bottom surface of the loading platform, and a drain pipe is disposed at a position lower than the bottom surface of the loading platform.

Patent document 1: japanese patent laid-open publication No. 2012 and 165758 (A)

Patent document 2: japanese patent laid-open No. 2001 and 047868 (A)

Patent document 3: japanese laid-open patent publication No. 2002-087148 (A)

In recent years, infectious diseases with high infectivity, such as foot-and-mouth disease, swine fever, and avian influenza, have spread to various livestock, and have become a big problem.

Here, since bacteria and viruses that are pathogens of the above-mentioned infectious diseases have very strong infectivity, there is a risk that invasion of pathogens and spread of contamination cannot be sufficiently suppressed even when feed, a feeding jig, and a feeding facility containing a photocatalytic material are used, as shown in patent document 1.

In addition, when the infectious disease occurs, the spread to other areas is prevented by restricting the movement of livestock around the area of occurrence. Further, even when livestock are transported in areas other than the area where movement is restricted, measures such as selecting a transport route so as to avoid other farms are taken.

However, when livestock are transported, because the livestock are accommodated in a narrow accommodation room, there is a risk that the spread of infectious diseases cannot be sufficiently prevented even if the aforementioned countermeasures are taken in infectious diseases caused by pathogens having very strong infectivity. When a pathogen invades the housing room from the outside during transportation, it is necessary to immediately kill the pathogen in order to prevent infection of livestock in the housing room.

Therefore, when livestock are transported, it is required to suppress the spread of pathogens such as bacteria and viruses more than ever.

Disclosure of Invention

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a container for transporting livestock, which can suppress the spread of pathogens such as bacteria and viruses to livestock accommodated in an accommodation chamber even when the livestock is transported, and can maintain the health of the transported livestock.

As a result of intensive studies to solve the problem, the present inventors have found that: in the copper member made of copper or a copper alloy, the action speed against pathogens is higher than that of the photocatalytic material, and the photocatalytic material is particularly excellent in antibacterial property and antiviral property, and can effectively suppress the spread of pathogens even when livestock are transported.

The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a livestock transport container used for storing and transporting livestock, the livestock transport container being characterized in that a copper layer made of copper or a copper alloy is provided on at least a part of an inner surface of a storage chamber for storing the livestock.

In the livestock transport container having such a configuration, since the copper layer made of copper or a copper alloy having a high action speed against pathogens and excellent antibacterial and antiviral properties is disposed on at least a part of the inner surface of the housing chamber for housing the livestock, it is possible to suppress the pathogens from spreading to the livestock housed in the housing chamber. Therefore, the livestock can be delivered while well maintaining the health state of the livestock.

In the livestock transport container of the present invention, the copper layer is preferably provided so as to occupy an area of 10% or more of the total area of the inner surface.

In this case, since the copper layer occupies an area of 10% or more of the total area of the inner surface of the housing room housing the livestock, the pathogens can be effectively killed, so that the pathogens can be further inhibited from spreading to the livestock within the housing room.

In the livestock transportation container of the present invention, the thickness of the copper layer is preferably in the range of 1 μm or more and less than 10 mm.

In this case, the thickness of the copper layer is set to 1 μm or more, so that the antibacterial property and the antiviral property can be maintained. On the other hand, since the thickness of the copper layer is less than 10mm, it is possible to suppress excessive weight of the housing chamber.

In the livestock transportation container of the present invention, the Cu content in the copper layer may be 40 mass% or more.

In this case, since the Cu content is 40 mass% or more, the Cu content can be secured, the antibacterial action and the antiviral action can be sufficiently exhibited, and the spread of pathogens can be suppressed.

In the livestock transportation container of the present invention, the Ag content in the copper layer may be in a range of 5 mass ppm or more and 1 mass% or less.

In this case, since the Ag content is 5 mass ppm or more, pathogens can be killed by the antibacterial action and the antiviral action by Ag ions. On the other hand, since the Ag content is 1 mass% or less, the content of expensive Ag can be suppressed, and the manufacturing cost can be reduced.

In the livestock transportation container of the present invention, it is preferable that the copper layer has a Cu content of 52 mass% or more and 56 mass% or less, a Ni content of 10 mass% or more and 12 mass% or less, a Mn content of 0.1 mass% or more and 1.0 mass% or less, and the balance of Zn and unavoidable impurities.

In this case, since the copper layer has the above composition, the antibacterial property and the antiviral property are particularly excellent, and the spread of pathogens can be further suppressed. Further, since the discoloration resistance is excellent, deterioration in appearance can be suppressed even when the composition is used for a long time.

In the livestock transportation container of the present invention, it is preferable that the copper layer has a Cu content of 69 mass% or more and 73 mass% or less, a Ni content of 1.5 mass% or more and 3.5 mass% or less, a Sn content of 0.3 mass% or more and 0.9 mass% or less, a P content of 0.01 mass% or more and 0.03 mass% or less, and the balance of Zn and unavoidable impurities.

In this case, since the copper layer has the above composition, the antibacterial property and the antiviral property are particularly excellent, and the spread of pathogens can be further suppressed. Further, since the discoloration resistance is excellent, deterioration in appearance can be suppressed even when the composition is used for a long time.

In the livestock transport container of the present invention, it is preferable that the copper layer is also provided on at least a part of an outer surface of the housing chamber.

In this case, even when pathogens such as bacteria and viruses adhere to the outer surface of the housing chamber, the pathogens can be killed by the antibacterial and antiviral actions of the copper layer, and the invasion of the pathogens from the outside can be sufficiently suppressed.

In the livestock transportation container of the present invention, the copper layer is preferably disposed so as to occupy an area of 10% or more of the total area of the outer surface.

In this case, since the copper layer occupies 10% or more of the total area of the outer surface of the housing chamber for housing the livestock, the pathogens adhering to the outer surface of the housing chamber can be effectively killed, and the invasion of the pathogens from the outside can be further suppressed.

In the livestock transportation vessel of the present invention, the copper layer may be provided so as to occupy 10% or more of the area of the bottom surface in the inner surface.

In this case, since the copper layer is provided so as to occupy 10% or more of the area of the bottom surface in the inner surface, even when a pig or the like touches the bottom surface with the tip of the nose, the antibacterial action and the antiviral action of the copper layer can kill pathogens, thereby further suppressing the spread of pathogens.

Alternatively, in the livestock transportation vessel of the present invention, the copper layer may be provided so as to occupy 10% or more of the area of the bottom surface and the side surface ranging from the bottom surface to a height of 50cm in the inner surface.

In this case, since the copper layer is provided so as to occupy 10% or more of the area of the bottom surface and the side surface from the bottom surface to the height of 50cm in the inner surface, even when a pig or the like touches the tip of the nose to the area from the bottom surface to the height of 50cm in the bottom surface or the side surface, the antibacterial action and the antiviral action of the copper layer can kill pathogens, and the spread of pathogens can be further suppressed.

According to the present invention, it is possible to provide a livestock transport container that can suppress the spread of pathogens such as bacteria and viruses to livestock accommodated in an accommodation chamber and maintain the health of the transported livestock, even when the livestock is transported.

Detailed Description

Hereinafter, a livestock transport container according to an embodiment of the present invention will be described.

The livestock transport container of the present embodiment is used as a loading platform of a livestock transport vehicle, for example. Examples of livestock to be delivered include cattle, horses, pigs, sheep, and birds.

Fig. 1 shows a livestock transport vehicle 1 including a livestock transport container (a loading platform for transporting livestock) according to an embodiment of the present invention.

The livestock transport vehicle 1 is composed of the livestock transport container 10 of the present embodiment and a transport vehicle 3 on which the livestock transport container 10 can be mounted.

As shown in fig. 1 to 3, a livestock transport container 10 according to an embodiment of the present invention includes a housing chamber 11 for housing livestock, and the housing chamber 11 is configured to be surrounded by a bottom surface 12, a side wall portion 13, an end surface portion 14, and a ceiling portion 15.

The side wall portion 13 is configured as follows: the lower portion is a panel portion, the upper portion is a fence portion, and outside air is introduced into the interior of the housing chamber 11 through the fence portion.

In the livestock transportation vessel 10 of the present embodiment, a copper layer 20 made of copper or a copper alloy is disposed on at least a portion of the inner surface of the housing chamber 11. In the present embodiment, as described above, the housing chamber 11 is configured to be surrounded by the bottom surface 12, the side wall portion 13, the end surface portion 14, and the ceiling portion 15, and therefore the copper layer 20 is disposed on at least a portion of the inner surface side of the bottom surface 12, the side wall portion 13, the end surface portion 14, and the ceiling portion 15.

The copper layer 20 made of copper or a copper alloy is excellent in antibacterial and antiviral properties, and can suppress the spread of pathogens.

Further, since feces of livestock may be deposited on the bottom surface 12, the copper layer 20 may not be provided. However, since pigs rub the tip of their nose against the bottom surface 12, it is preferable to dispose the copper layer 20 also on the bottom surface 12. In this manner, the arrangement position of the copper layer 20 is preferably set according to the livestock to be transported.

In the present embodiment, the copper layer 20 is preferably disposed so as to occupy 10% or more of the total area of the inner surface of the housing chamber 11.

The copper layer 20 preferably occupies an area of 20% or more, more preferably 30% or more, of the total area of the inner surface of the housing chamber 11. Although not particularly limited, the copper layer 20 may be provided so as to occupy an area of 10% or more and 100% or less or 98% or less of the total area of the inner surface of the housing chamber 11.

In the present embodiment, when livestock such as pigs whose nose tip is in contact with the bottom surface are transported, the copper layer 20 may be disposed so as to occupy 10% or more of the area of the bottom surface in the inner surface of the housing chamber 11. Alternatively, the copper layer 20 may be provided so as to occupy 10% or more of the area of the bottom surface and the side surface from the bottom surface to the height of 50cm in the inner surface of the housing chamber 11.

The copper layer 20 preferably occupies 20% or more, more preferably 30% or more, of the area of the bottom surface of the inner surface of the housing chamber 11. Although not particularly limited, the copper layer 20 may occupy 10% or more and 100% or less or 98% or less of the area of the bottom surface in the inner surface of the housing chamber 11. The area of the bottom surface and the side surface extending from the bottom surface to a height of 50cm in the inner surface of the housing chamber 11 is preferably 20% or more, and more preferably 30% or more. Although not particularly limited, the area of the bottom surface and the side surface extending from the bottom surface to a height of 50cm may be 10% or more and 100% or less or 98% or less of the inner surface of the housing chamber 11.

In the present embodiment, it is preferable that a copper layer 20 made of copper or a copper alloy is also provided on at least a part of the outer surface of the housing chamber 11.

In the present embodiment, the copper layer 20 is preferably disposed so as to occupy 10% or more of the total area of the outer surface of the housing chamber 11.

The copper layer 20 preferably occupies an area of 20% or more, more preferably 30% or more, of the total area of the outer surface of the housing chamber 11. Although not particularly limited, the upper limit of the proportion of the copper layer 20 in the total area of the outer surface may be set to 100% or less. The upper limit of the Cu content of the copper or copper alloy of the copper layer 20 constituting the outer surface of the housing chamber 11 may be 99.999 mass% or less, or 75 mass% or less.

The copper layer 20 may be disposed at a desired portion of the inner surface (and the outer surface) of a platform (a housing chamber) of a conventional livestock transporter.

The method of forming the copper layer 20 is not particularly limited, and the copper plate may be mounted by welding, screwing, adhesion, or the like, or may be formed by plating or the like. Since a loading platform (housing chamber) of a conventional livestock carrier is made of, for example, aluminum or an aluminum alloy, stainless steel, ordinary steel, or the like, a method for forming the copper layer 20 is preferably selected in consideration of the bondability of these materials to the copper layer.

In the present embodiment, the thickness of the copper layer 20 is preferably set to be in the range of 1 μm or more and less than 10 mm.

If the thickness of the copper layer 20 is 1 μm or more, the copper layer 20 is less likely to be worn, and an antibacterial effect and an antiviral effect can be obtained within a certain period of time. Further, since the density of copper is high, by setting the thickness of the copper layer 20 to less than 10mm, it is possible to suppress an excessive increase in the weight of the livestock transport container 10.

The lower limit of the thickness of the copper layer 20 is preferably 30 μm or more, and more preferably 80 μm or more. On the other hand, the upper limit of the thickness of the copper layer 20 is preferably 5mm or less, and more preferably 2mm or more.

The copper or copper alloy constituting the copper layer 20 may be applied if it has an antibacterial action and an antiviral action based on copper.

Here, the Cu content of the copper or copper alloy constituting the copper layer 20 is preferably 40 mass% or more. By securing the Cu content, the antibacterial and antiviral effects by copper can be reliably secured.

The Cu content in the copper or copper alloy constituting the copper layer 20 is more preferably 45 mass% or more, and still more preferably 50 mass% or more. Although not particularly limited, the Cu content of the copper or copper alloy constituting the copper layer 20 may be 40 mass% or more and 100 mass% or less. The upper limit of the Cu content of the copper or copper alloy constituting the copper layer 20 may be 99.999 mass% or less, or 75 mass% or less.

As copper or a copper alloy constituting the copper layer 20, copper or a copper alloy having an Ag content in a range of 5 mass ppm or more and 1 mass% or less can be used.

Since Ag has antibacterial and antiviral effects by ionization, it can exhibit antibacterial and antiviral effects based on Ag ions when used in a humid environment. On the other hand, since Ag is expensive, an increase in the content thereof leads to an increase in cost. Therefore, as described above, the Ag content is preferably specified.

Here, in order to reliably obtain the antibacterial action and the antiviral action by the Ag ions, the lower limit of the Ag content is preferably 7 mass ppm or more, and more preferably 10 mass ppm or more. On the other hand, in order to further suppress the cost, the upper limit of the Ag content is preferably 0.7 mass% or less, and more preferably 0.5 mass% or less.

In addition, in the case where Ag is contained as an impurity instead of being intentionally added, the Ag content may be less than 5 mass ppm.

As copper or copper alloy constituting the copper layer 20, a copper alloy having the following composition can be used: the Cu content is in the range of 52-56 mass%, the Ni content is in the range of 10-12 mass%, the Mn content is in the range of 0.1-1.0 mass%, and the balance is Zn and unavoidable impurities.

The copper alloy having the above composition has excellent antibacterial and antiviral properties, good workability, and discoloration resistance, and is particularly suitable as a material for the copper layer 20. Further, the copper sheet is also excellent in weldability, and the copper layer 20 can be formed by welding the copper sheet. In addition, the silver white color has a yellowish hue and is excellent in aesthetic properties.

As copper or copper alloy constituting the copper layer 20, a copper alloy having the following composition can be used: the Cu content is in the range of 69-73 mass%, the Ni content is in the range of 1.5-3.5 mass%, the Sn content is in the range of 0.3-0.9 mass%, the P content is in the range of 0.01-0.03 mass%, and the balance is Zn and unavoidable impurities.

The copper alloy having the above composition has excellent antibacterial and antiviral properties, good workability, and discoloration resistance, and is particularly suitable as a material for the copper layer 20. Further, the copper sheet is also excellent in weldability, and the copper layer 20 can be formed by welding the copper sheet. Further, the plate was slightly yellowish white in color and had excellent appearance.

Further, in the above copper layer 20, the average crystal grain size is preferably less than 10 mm.

By setting the average crystal grain size to less than 10mm, corrosion resistance can be improved, and early corrosion of the copper layer 20 due to feces and the like can be suppressed.

The average crystal grain size of the copper layer 20 is more preferably less than 2mm, and still more preferably less than 1 mm.

In the copper layer 20, the surface roughness is preferably in the range of 0.8 to 25. The surface roughness is Ra specified in JIS B0601-2001.

When the surface roughness is 0.8 or more, the antibacterial action and the antiviral action can be effectively exhibited. On the other hand, if the surface roughness is 25 or less, the stress on the livestock can be reduced when the livestock comes into contact with the surface.

The lower limit of the surface roughness of the copper layer 20 is more preferably 1.6 or more. The upper limit of the surface roughness of the copper layer 20 is more preferably 12.5 or less.

According to the livestock transport container 10 of the present embodiment configured as described above, since the copper layer 20 made of copper or a copper alloy having a high action rate on pathogens and excellent antibacterial and antiviral properties is disposed on at least a part of the inner surface of the housing room 11 for housing livestock, it is possible to suppress pathogens from spreading to livestock in the housing room 11. Therefore, the livestock can be stably transported while well maintaining the health state of the livestock.

In the present embodiment, when the copper layer 20 is provided so as to occupy 10% or more of the total area of the inner surface of the housing chamber 11, pathogens can be effectively killed, and the spread of pathogens to livestock in the housing chamber 11 can be further suppressed.

In the present embodiment, even when the copper layer 20 made of copper or a copper alloy is disposed on at least a portion of the outer surface of the housing chamber 11, even when pathogens such as bacteria and viruses adhere to the outer surface of the housing chamber 11, the pathogens can be immediately killed by the antibacterial action and the antiviral action of the copper layer 20, and the intrusion of the pathogens from the outside can be sufficiently suppressed.

In the present embodiment, when the copper layer 20 is provided so as to occupy 10% or more of the total area of the outer surface of the housing chamber 11, pathogens adhering to the outer surface of the housing chamber 11 can be effectively killed, and invasion of pathogens from the outside can be further suppressed.

In the present embodiment, when the copper layer 20 is provided so as to occupy 10% or more of the area of the bottom surface of the inner surface of the housing chamber 11, even when a pig or the like touches the bottom surface of the inner surface of the housing chamber with the tip of the nose, the antibacterial action and the antiviral action of the copper layer 20 can kill pathogens, thereby further suppressing the spread of pathogens.

Alternatively, in the present embodiment, in the case where the copper layer 20 is provided so as to occupy 10% or more of the area of the bottom surface and the side surface from the bottom surface to the height of 50cm in the inner surface of the housing chamber 11, even in the case where a pig or the like touches the tip of the nose to the region from the bottom surface to the height of 50cm of the bottom surface or the side surface, the antimicrobial action and the antiviral action of the copper layer 20 can kill pathogens, and the spread of pathogens can be further suppressed.

In the present embodiment, when the thickness of the copper layer 20 is set to be in the range of 1 μm or more and less than 10mm, the antibacterial property and the antiviral property can be maintained for a certain period of time, and the copper layer 20 can be prevented from being excessively increased in weight, so that the livestock transportation container 10 can be reduced in weight.

In the present embodiment, when the Cu content of the copper layer 20 is 40 mass% or more, the Cu content in the copper layer 20 can be secured, and the antibacterial action and the antiviral action can be sufficiently exhibited. Therefore, the spread of pathogens within the housing room 11 can be suppressed.

In the present embodiment, when the Ag content in the copper layer 20 is set to be in the range of 5 ppm by mass or more and 1% by mass or less, the antibacterial action and the antiviral action based on the eluted Ag ions can be obtained when used in a wet environment, and the antibacterial property and the antiviral property can be improved, and the expensive Ag content can be suppressed, thereby reducing the manufacturing cost.

In addition, in the present embodiment, the copper layer 20 is composed of a copper alloy having the following composition: in this case, the antibacterial and antiviral properties are excellent, and the spread of pathogens can be further suppressed, in particular, when the Cu content is in the range of 52 mass% to 56 mass%, the Ni content is in the range of 10 mass% to 12 mass%, the Mn content is in the range of 0.1 mass% to 1.0 mass%, and the balance is Zn and unavoidable impurities. Further, since the discoloration resistance is excellent, deterioration in appearance can be suppressed even when the composition is used for a long time.

In the present embodiment, the copper layer 20 is made of a copper alloy having the following composition: in this case, the antibacterial and antiviral properties are particularly excellent, and the spread of pathogens can be further suppressed. Further, since the discoloration resistance is excellent, deterioration in appearance can be suppressed even when the composition is used for a long time.

The embodiments of the present invention have been described above, but the present invention is not limited to these embodiments, and modifications can be made as appropriate without departing from the technical spirit of the present invention.

For example, although the livestock transport container applied as the loading platform of the livestock transport vehicle shown in fig. 1 is described in the present embodiment, the present invention is not limited thereto, and may be applied to a livestock transport vehicle having another configuration.

Further, the livestock transport vehicle may be a livestock transport container used when transporting livestock by other transport means such as a ship, an airplane, a train, or the like.

Examples

The results of the confirmation experiment performed to confirm the effects of the present invention will be described below.

First, a copper plate (thickness 3mm) made of copper or a copper alloy shown in table 1 was prepared. In the present example, the copper layer was formed by mounting these copper plates on the surface of an iron plate made of ordinary steel.

In comparative example 1, the surface of the iron plate made of ordinary steel was exposed. In comparative example 2, a photocatalytic layer (titanium oxide film: 1 μm in thickness) was formed on the surface of an iron plate made of ordinary steel.

Then, the test pieces of the present invention and comparative examples were used to evaluate antibacterial properties. The evaluation results are shown in table 1.

The method for testing antibacterial properties was carried out according to JIS Z2801. As each test piece and control (comparative example 1), a stainless steel plate having no copper layer was used. The surface of each test piece was inoculated with a certain amount of staphylococcus aureus, and viable count (cfu) was quantified with the passage of time. In comparative example 2, the test using the titanium oxide film was performed by irradiating ultraviolet rays. Using the quantified viable cell count, the bactericidal ratio (log cfu/4 cm) obtained by the following formula was determined²) The antibacterial property is set.

Log (viable count of each test piece [ cfu ] at each time/viable count of stainless steel sheet test piece having no copper layer [ cfu ] at each time)

The test time was set to a maximum of 120 minutes. In the stainless steel sheet of comparative example 1, there was almost no change in the number of viable bacteria during the test time, and the number of viable bacteria was regarded as the same constant number as in the initial state regardless of the time.

The test was performed with a maximum of N-3. Since the results in most examples have a proportional relationship between time and sterilization rate at the initial stage of the experiment, the relationship between time and sterilization rate was fitted to a linear expression in order to eliminate the influence of variation. However, the sterilization rate is less than 10^-5Is deemed to be completely sterilized and is therefore not used for fitting calculations. The sterilization rate was 0 at time 0 minutes. That is, the fitting equation is a linear equation passing through the origin.

The antibacterial properties in table 1 show the sterilization rate at each time calculated from the approximate expression thus obtained.

[ Table 1]

In comparative example 1 in which no copper plate (copper layer) was disposed, the number of viable bacteria did not change even after a long period of time, and no antibacterial effect was observed. Therefore, it was confirmed that the spread of pathogenic bacteria could not be suppressed.

In comparative example 2 in which the photocatalytic layer (titanium oxide film) was formed, although a decrease in the number of viable bacteria was observed, it took time until the bacteria were killed, and therefore the antibacterial effect was insufficient. Therefore, it was confirmed that pathogenic bacteria could not be killed in advance and the spread of pathogenic bacteria could not be sufficiently suppressed.

On the other hand, in examples 1 to 16 of the present invention in which the copper plate (copper layer) was disposed, the number of viable bacteria after contact with the copper plate (copper layer) was reduced in a short time, and it was confirmed that the antibacterial effect was excellent. Therefore, pathogenic bacteria can be killed at an early stage, and it has been confirmed that the spread of pathogenic bacteria can be sufficiently suppressed.

In summary, the following were confirmed: according to the present invention, it is possible to provide a container for transporting livestock, which can suppress the spread of pathogens such as bacteria and viruses to livestock accommodated in an accommodation chamber and can maintain the health of the transported livestock, even when the livestock is transported.

Industrial applicability
