Description

Technical Field

[0001] The present invention relates to a device for reducing chicken coccidia protozoa using a microwave field, and more specifically, to a device for reducing chicken coccidia protozoa using a microwave field as follows, namely, in the process of raising broiler chickens, in order to recycle litter for the second to fifth feedings after the first feeding, hardened litter is crushed by a crushing device to create a ground similar to the first feeding environment and the microwave field of the microwave device is irradiated toward the crushed litter, thereby reducing or killing the number of chicken coccidia protozoa, viruses, bacteria, fungi and other pathogens in the litter, so that broiler chickens can be raised healthily and safely by reducing pathogenicity and mortality, thereby bringing huge economic benefits to poultry farms.

[0002] This achievement was researched and invented with the support of the Ministry of Agriculture, Forestry, Animal Husbandry and Food and the Institute of Agricultural, Forestry and Food Technology Planning and Evaluation (Project unique number: 1545027936, detailed project number: 322056022SB020). Background Art

[0003] In the global aquaculture industry, coccidia of the genus Eimeria are important coccidia that cause economic losses of approximately US$3 billion (USD) each year (Dalloul and Lillehoj, 2006; Williams, 1999). Chickens infected with Eimeria spp. not only suffer from diarrhea and weakness, but are also prone to bleeding caused by intestinal lesions due to weight loss caused by reduced feed efficiency, and are susceptible to infection by other pathogens such as bacteria or viruses (Morris and Gasser, 2006; Min et al., 2013). The proportion of poultry farms infected with Eimeria spp. in South Korea is approximately 70% to 80% (Du and Hu, 2004; Lee et al., 2010; Flores et al., 2022).

[0004] In addition, there are seven main types of coccidia that induce Eimeria in chickens (Eimeria acervulina, Eimeria brunetti, Eimeria maxima, Eimeria mitis, Eimeria necatrix, Eimeria praecox and Eimeria tenella). Among them, Eimeria tenella, which parasitizes in the cecum, has the highest pathogenicity and mortality rate, causing huge economic losses to poultry farms (Allen and Fetterer, 2002).

[0005] To prevent this situation, although the anticoccidial preparation disclosed in Korean Patent No. 10-2016-0145328 can effectively inhibit Eimeria galli, long-term use is not only prone to the emergence of drug-resistant protozoan strains (Chapman, 1997; Usman et al., 2011; Flores et al., 2022), but also has been completely banned in the European Union since 2006 due to the problem of antibiotic residues in livestock products.

Figure 2 A side view of a pulverizing device according to an embodiment of the present invention is shown. Figure 3 This is a working diagram showing the operation of a pulverizing device according to an embodiment of the present invention. Figure 4 It is a front view showing a microwave device according to an embodiment of the present invention.

[0025] like Figures 1 to 4 As shown, the chicken coccidia protozoa reduction device using a microwave field of the present invention includes: a main body 10, having a plurality of movable wheels 11 on the lower side, and a handle 12 for controlling the moving direction on the upper side; a crushing device 20, disposed on the front lower side of the above-mentioned main body 10, for crushing and overturning the chicken house litter during movement; a microwave device 30, disposed on the lower side of the above-mentioned main body 10, for irradiating the chicken house litter crushed and overturned by the crushing device 20 with a microwave field to reduce chicken coccidia protozoa; and a control unit 40, disposed on the upper surface of the above-mentioned main body 10, connected to the microwave device 30, and for controlling the microwave field of the above-mentioned microwave device 30.

[0026] like Figure 1As shown, the main body 10 is a quadrilateral metal plate, a handle portion 12, a control portion 40, a motor portion 50, and a battery portion 60 are formed at the upper portion of the main body 10, and a wheel portion 11, a microwave device 30, and a crushing device 20 are formed at the lower portion of the main body 10.

[0027] The wheel portion 11 of the main body 10 enables the main body 10 to be separated from the ground and move. The wheel portion 11 is provided with a plurality of legs of a predetermined length on the lower surface of the metal plate, and the ends of the legs are respectively provided with wheels for moving the main body 10. In this case, the wheels are connected to the ends of the legs in a manner that they can be switched in the front, back, left, and right directions, and the wheels are also provided with additional braking devices for controlling movement.

[0028] Moreover, the handle portion 12 of the main body 10 is disposed at the middle rear of the upper surface of the metal plate. The handle portion 12 is formed to protrude from the upper rear side of the metal plate and can be held by a user to push the main body 10. The handle portion 12 is also provided with a switch portion 13, which is electrically connected to the control portion 40 and is used to operate the control portion 40. In this case, the switch portion 13 is formed with a switch capable of operating the on / off of the motor portion 50, the microwave field intensity and time of the microwave device 30, and the like.

[0029] like Figures 1 to 3 As shown, the crushing device 20 is arranged on the front lower side of the main body 10, and is used to crush and overturn the litter in the chicken house during movement. It consists of a connecting rod 21, a crushing blade 22, and a partition plate 23.

[0030] The connecting rod 21 is provided with a plurality of connecting rods on the front lower side of the main body 10, such as Figures 2 to 3 As shown, the connecting rod 21 is connected to the main body 10 through a hinge & gear and can rotate, and the gear is connected to an additional motor, and the end of the connecting rod 21 can rotate through the operation of the motor. In this case, the motor is connected to the battery unit 60 and the control unit 40, receives power from the battery unit 60, and is controlled by the control unit 40. That is, the connecting rod 21 is rotated by the motor. Under normal circumstances, when the main body 10 moves, it rotates toward the upper side and prevents the crushing device 20 from contacting the ground. During operation, the connecting rod 21 is rotated toward the lower side and the crushing blade 22 of the crushing device 20 enters the specified interval along the inner side of the litter.

[0031] Furthermore, the crushing blade 22 is connected between the connecting rods 21 via the rotating shaft 24, and directly crushes and overturns the chicken house litter by the rotation of the rotating shaft 24. The crushing blade 22 is formed in plurality along the rotating shaft 24 and is spaced apart from each other, so that a wide range of litter can be crushed and overturned. That is, the crushing blade 22 can not only overturn the litter, but also crush the hardened litter into small pieces.

[0032] Moreover, the partition plate 23 is arranged on the connecting rod 21 located on the upper side of the plurality of crushing blades 22, and is used to protect the crushing blades 22 from external influences and prevent the straw crushed by the crushing blades 22 from scattering to the upper part. The partition plate 23 is a curved shape corresponding to the rotation of the crushing blades 22, and is used to protect and prevent scattering.

[0033] On the other hand, a motor unit 50 is provided on one side of the upper portion of the main body 10 , and is connected to the rotating shaft 24 of the crushing blade 22 via a connecting member such as a chain, so as to rotate the rotating shaft 24 . The motor unit 50 operates under the control of the control unit 40 .

[0034] like Figure 1 and Figure 4 As shown, the microwave device 30 is disposed on the lower side of the main body 10, and irradiates microwave field to the chicken house litter crushed and overturned by the crushing device 20 to reduce or kill chicken coccidia protozoa. In this case, the microwave device 30 irradiates microwave field toward the lower side.

[0035] Among them, the above-mentioned microwave devices 30 are arranged in plurality on the lower side of the main body 10, and the above-mentioned multiple microwave devices 30 are connected to the control unit 40 and controlled by the control unit 40. The microwave field (microwave) of one microwave device is 700W, and the irradiation time is about 20 seconds to 30 seconds to reduce or kill the number of chicken coccidia protozoa.

[0036] Moreover, if Figure 4 As shown, a conditioning plate 31 is formed at the lower edge of the microwave device 30 for regulating the propagation of the irradiated microwave field. The conditioning plate 31 is connected to all surfaces of the lower edge of the microwave device 30 through hinge shafts 32. The microwave field is widely propagated or concentrated on one point through the rotation of the hinge shafts 32.

[0037] Furthermore, a plurality of hinge shafts 32 of the cooking plate 31 are formed along the lower edge of the microwave device 30, and are connected to each other in a state where a gear such as a worm gear is formed on one side of the hinge shaft 32. If one hinge shaft 32 rotates, the other hinge shaft 32 also rotates in the same direction at the same time, thereby adjusting the angle of the cooking plate 31 in the same direction. In this case, one hinge shaft 32 among the plurality of hinge shafts 32 is connected to an additional motor and rotates, and the motor is connected to the battery unit 60 and the control unit 40, receives power from the battery unit 60, and is controlled by the control unit 40.

[0038] like Figure 1As shown, the control unit 40 is connected to the microwave device 30, the motor unit 50, the battery unit 60, and multiple motors through electrical signals. The control unit 40 is arranged on the upper surface of the main body 10 and is connected to the microwave device 30 to control the microwave field intensity, time, power, etc. of the microwave device 30.

[0039] On the other hand, a microwave device 30, a control unit 40, a motor unit 50 and a battery unit 60 for supplying power to multiple motors are also provided on the other side of the upper portion of the main body 10. The battery unit 60 is rechargeable and is connected to an external power source to charge power.

[0040] The following describes the experimental results of killing chicken coccidia protozoa using the microwave field of the present invention.

[0041] 1. In vitro experimental results: Microwave field effectively eliminates chicken coccidia oocysts

[0042] Figure 5 A graph showing the elimination of chicken coccidia protozoa using a microwave field according to an embodiment of the present invention is shown in FIG. Figure 5 As shown, oocysts present in broiler farm feces (80 grams (gram) -100 grams (gram)) were irradiated with 700W microwaves (microwav) for 60 seconds (T-60), 30 seconds (T-30), 20 seconds (T-20), and 0 seconds (control group (control)).

[0043] In this case, the irradiated samples were placed at room temperature for 5 days, and then the number of oocysts was confirmed using an oocyst counting plate (McMaster chamber). Compared with the control group (control), the treatment group showed a significant reduction in oocysts.

[0044] ***p<0.001, **p<0.01, *p<0.05 compared to the control group showed statistical significance. The results represent the mean±standard deviation.

[0045] 2. In vivo experimental results: The oocysts of chicken coccidia (Eimeria tenella) were irradiated with microwave fields and the irradiated oocysts were orally administered to chickens to verify the effect.

[0046] Table 1

[0047]

[0048] Table 1 shows the results of confirming the elimination of chicken coccidia oocysts by microwave field in chickens. After Eimeria tenella was uniformly mixed with sawdust (50 gram-60 gram), the sample was irradiated with 700W microwave for 20 seconds (T-20) and 0 seconds (control group, T-0).

[0049] The number of oocysts present in the irradiated samples was confirmed using an oocyst counting chamber (McMaster chamber). 10,000 sporulated oocysts were orally administered to each chicken. The results of the treated groups were compared with the control group (control, T-0). During the experiment, the diet without anticoccidial agents was fed. The results are expressed as mean ± standard deviation.

[0050] 2-1. Fecal oocyst number decreases

[0051] - After the sample was administered to the chickens, feces were collected for 6 to 9 days and the number of oocysts was measured (n=15). Compared with the control group (control, T-0), the number of oocysts in the 20-second (T-20) group was reduced by 79%.

[0052] 2-2. Increased body weight gain

[0053] - After the sample was administered to chickens, the body weight change was measured over a period of 9 days (n=15). The body weight of the 20-second (T-20) group increased by 6.9% compared to the control group.

[0054] 2-3. Decrease in intestinal lesion score

[0055] - After the sample was administered to chickens, the degree of intestinal lesions was measured within 7 days (n=7). The intestinal lesions in the 20-second (T-20) group were significantly reduced compared to the control group.

[0056] 3. Summary

[0057] In the above experiment, a microwave field was used to kill coccidian oocysts present in a chicken farm.

[0058] - In vitro experiments confirmed that microwave fields directly destroyed oocysts (the number of oocysts present in the sample decreased)

[0059] - In vivo experiments confirmed that microwave fields indirectly destroyed oocysts (number of oocysts excreted in feces, weight gain effect, and reduction in intestinal pathology index).
