Description

TECHNICAL FIELD The present invention relates to a method for rearing chickens for egg collection, and an ultra-fine bubble maker for poultry farming and an apparatus for producing drinking water for poultry farming used in the method.

Conventionally, in a poultry house where egg-laying hens are raised and eggs are collected, the chickens are fed through a feeding trough arranged along the cage, and a water supply pipe is arranged along the cage. Water is being supplied through the provided water pick.

In general, when raising Boris Brown chickens, 120-day-old chickens are introduced into a poultry house, and feeding and water supply to the introduced chickens are started to start raising them. The chickens introduced into the poultry house gradually start laying eggs, and after reaching 50% egg-laying rate at around 150 days of age, it reaches the maximum of about 90% at around 200 days of age. After that, the egg production rate gradually decreased, and when the egg production rate reached 70% or less at around 600 days of age, the chickens were removed from the poultry house and replaced with new chickens.

It is known that it is effective to increase the weight of chicks from 1 to 28 days of age in order to increase egg productivity. Therefore, various feeds have been proposed (see, for example, Patent Document 1).

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

In the poultry farming method of the embodiment of the present invention, eggs are obtained from egg-laying hens by providing drinking water containing ultra-fine bubbles of air as gas to the hens.

Ultra-fine 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, ultra-fine bubbles have a lower floating speed than microbubbles, which are bubbles with a diameter of 1 μm or more, and can stay in liquid for a long time. In addition, ultra-fine bubbles have a larger surface area than microbubbles, have a self-pressurizing effect, and have a negative charging effect. Based on these characteristics, it is possible to increase the efficiency of egg production for egg-laying hens by supplying water to which ultra-fine air bubbles have been added as drinking water to egg-laying hens.

Egg-laying hens generally start laying eggs around 150 days of age, for example in the case of the Boris Brown breed. Here, the start of egg-laying can be brought forward by about 10 to 20 days by feeding drinking water to which ultra-fine air bubbles have been added to non-laying hens.

In addition, by feeding egg-laying chickens with drinking water to which ultra-fine air bubbles were added, 76 g or more of large chicken eggs were collected compared to the case of feeding drinking water to which no ultra-fine air bubbles were added. can be increased from 1.5 times to about 2 times.

In addition, by feeding egg-laying chickens with drinking water added with ultra-fine air bubbles, even if feed with a CP (crude protein) ratio of 16% is given, M size (58 g or more and less than 64 g) The number of eggs laid above can be 95% or more of the total number of eggs laid. Therefore, feed costs can be effectively reduced.

The water containing ultra-fine air bubbles used as drinking water in the present embodiment is not particularly limited as long as the diameter of the ultra-fine air bubbles is 1 nm or more and 1000 nm or less. If the diameter of the ultra-fine air bubbles exceeds 1000 nm, the egg production efficiency may not be sufficiently improved. Preferably, the diameter of ultra-fine bubbles of air contained in drinking water is 10 nm or more and 500 nm or less, more preferably 20 nm or more and 300 nm or less. When the ultra-fine bubbles of air contained in the drinking water have a diameter of 20 nm or more and 300 nm or less, the production efficiency of chicken eggs can be effectively increased. Also, the weight of eggs produced can be effectively increased. In this embodiment, the diameter of the ultra-fine bubbles was measured by a laser diffraction/scattering method.

The ultra-fine air bubble-containing water used as drinking water in the present embodiment has a concentration of 1×10 ⁷ bubbles/mL or more, and the upper limit is not particularly limited. 10 ¹² cells/mL or less. If the concentration of air ultra-fine bubbles is less than 1×10 ⁷ bubbles/mL, the egg production efficiency may not be sufficiently improved. Preferably, the concentration of ultra-fine bubbles in the air is 1×10 ⁷ bubbles/mL or more and 3×10 ⁸ bubbles/mL or less, and particularly preferably 1×10 ⁸ bubbles/mL or more and 2×10 ⁸ bubbles/mL or less. is. By setting the concentration of ultra-fine bubbles in the air of drinking water to 1×10 ⁸ bubbles/mL or more and 2×10 ⁸ bubbles/mL or less, the production efficiency of chicken eggs can be effectively increased. Also, the weight of eggs produced can be effectively increased.

Potable water containing ultra-fine bubbles of air may be fed to egg-laying hens at any stage. Preferably, the drinking water containing the ultra-fine bubbles of air can begin feeding the chickens when they are introduced into the egg-laying house. For example, 120-day-old giant chicks introduced into a poultry house can be started on drinking water containing ultra-fine bubbles of air. By providing feed and drinking water to the chickens introduced into the poultry house and rearing them, the egg production rate of the chickens increases with the passage of time, and the amount of eggs collected increases. By adopting drinking water containing ultra-fine air bubbles as the drinking water supplied in this poultry house, it is possible to effectively advance the timing at which chickens start laying eggs.

Drinking water containing ultra-fine bubbles of air may be fed to chickens at any time between hatching and introduction into the egg house. The growth of chicks can be promoted by feeding drinking water containing ultra-fine bubbles of air at the stage of juvenile, medium or large chicks.

In addition, chickens introduced into a poultry house for egg collection may be fed with drinking water containing ultra-fine bubbles of air from any point of time. In addition, chickens introduced into a poultry house for egg collection may be fed with drinking water containing ultra-fine bubbles of air for a certain period of time.

In the ultra-fine bubble generator 26, a mixed fluid of water and air is pressure-fed by the cascade pump 23, and from the supply pipe 41, which is the upstream part of the ultra-fine bubble generator 26 in the return path 24 and the discharge path 25, from the casing. 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 through the inflow openings 35b and 36b on the outer surface of the atomization block 28. As shown in FIG. The mixed fluid guided to the first introduction passage 35 is discharged into the first swirl chamber 31 through the discharge opening 35 a to form 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. Further, the mixed fluid guided to the second introduction path 36 is discharged into the second swirl chamber 33 through the discharge opening 36 a to form a swirl flow in the second swirl chamber 33 . A stable swirl flow is formed in the second swirl chamber 33 by the second introduction path 36 extending in the tangential direction of the second swirl chamber 33 and forming an inclination angle θ toward the other end.

Dispensed. The swirling flows discharged from the first discharge hole 32 and the second discharge hole 34 are swirled in opposite directions and collide with each other in the collision chamber 38 with a large impact force. As a result, the gases of the mixed fluid are effectively atomized to generate ultra-nanobubbles. The water containing the air ultra-nanobubbles thus generated is guided from the collision chamber 38 through the inflow openings 39a, 39a, . . . · is discharged to the discharge pipe 42 from. This discharge pipe 42 is downstream of the return path 24 and the discharge path 25 of the ultra-fine bubble generator 26 . The water containing the ultra-fine air bubbles generated by the ultra-fine bubble generator 26 is guided to the downstream side of the return path 24 and the discharge path 25 . That is, water containing ultra-fine air bubbles flows downstream of the return path 24 from the first ultra-fine bubble generator 26A, and ultra-fine air bubbles flow downstream of the discharge path 25 from the second ultra-fine bubble generator 26B. Water containing bubbles flows. The bubbles produced by the ultra-fine bubble producing device 26 are not limited to ultra-fine bubbles, and may include microbubbles depending on operating conditions, or may produce only microbubbles.

This bubble water production device 3 adjusts the opening of the mixed air amount adjustment valve 29, the discharge flow rate or discharge pressure of the mixed water from the submersible pump 21 and the cascade pump 23, and the opening of the flow rate adjustment valve 27. The particle size and concentration of the ultra-fine bubbles and microbubbles from the discharge path 25 can be adjusted.

For example, if the opening degree of the flow control valve 27 increases, the concentration of ultra-fine bubbles and/or microbubbles increases, the diameter of the bubbles decreases, and the amount discharged from the discharge path 25 decreases. . Along with this, the standard deviation of the diameters of the bubbles produced decreases, narrowing the width of the distribution and concentrating the diameters of the bubbles in a narrow range of relatively small values. On the other hand, when the opening degree of the flow control valve 27 is decreased, the concentration of ultra-fine bubbles and/or microbubbles is decreased, the diameter of the bubbles is increased, and the discharge amount from the discharge path 25 is increased. . Along with this, the standard deviation of the diameter of the generated bubbles expands, the width of the distribution widens, and the diameter of the bubbles spreads over a wide range from relatively small values to large values.

In addition, 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 ultra-fine bubbles and/or microbubbles increases, the diameter of the bubbles decreases, and the discharge Emissions from path 25 are increased. In a region where the discharge pressure is higher than 1 MPa, the concentration of ultra-fine bubbles and/or microbubbles decreases and the diameter of the bubbles 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 ultra-fine bubbles and/or microbubbles decreases, the diameter of the bubbles expands, and the discharge Emissions from path 25 are reduced. In a region where the ejection pressure is higher than 1 MPa, the bubble diameter of the ultra-fine bubbles and/or microbubbles increases and the bubble diameter decreases.

Further, by increasing the opening degree of the mixed air amount adjustment valve 29 of the ejector 22, the ratio of bubbles of 1 μm or more among the bubbles discharged from the discharge path 25 increases, while the mixed air amount adjustment valve 29 is opened. By decreasing the degree, the proportion of bubbles having a diameter of 1 μm or more among the bubbles discharged from the discharge path 25 is reduced. For example, when the mixed air amount adjustment valve 29 sets the air mixture amount of the ejector 22 to 0.4 L/min, the bubbles discharged from the discharge path 25 have a diameter of more than 1 μm, and the proportion of bubbles exceeding 1 μm increases. Microbubbles are generated. On the other hand, if the air mixture amount of the ejector 22 is set to 0.1 L/min by the mixed air amount adjustment valve 29, most of the bubbles discharged from the discharge path 25 have a diameter of less than 1 μm, and are substantially ultra-fine bubbles. is generated.

In addition, this bubble water production device 3 measures the concentration of ultra-fine 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 can be adjusted to adjust the concentration of the ultra-fine bubbles in the discharge path 25 . For example, when the concentration of ultra-fine bubbles in the discharge path 25 is lower than the target value, the opening of the flow control valve 27 is increased to increase the flow rate of the return path 24, thereby increasing the ultra-fine bubbles discharged from the discharge path 25. concentration increases.

In addition, this bubble water production device 3 is provided with a second flow control valve upstream of the second ultra-fine bubble production device 26B in the discharge path 25, and the opening degree of this second flow control valve and the mixed air amount control valve 29, the opening of the flow control valve 27 of the return path 24, and the discharge pressure of the submersible pump 21 and the cascade pump 23, the particle size and concentration of the ultra-fine bubbles discharged from the discharge path 25 are adjusted. may be adjusted.

The bubble water producing device 3 is provided with a control device (not shown), which controls the opening degree of the mixed air amount adjusting valve 29, the opening degree of the flow rate adjusting valve 27, and the opening degree of the second flow rate adjusting valve. The particle size and concentration of the ultra-fine bubbles from the discharge path 25 may be adjusted by controlling the temperature and the discharge pressure of the submersible pump 21 and the cascade pump 23 .

In this manner, the bubble water producing apparatus 3 can stably form ultra-fine bubbles of 50 to 70 nm. Note that the return path 24, the flow control valve 27, and the first ultra-fine bubble generator 26A may not be provided. That is, only the second ultra-fine bubble generator 26B may be provided in the discharge path 25 downstream of the cascade pump 23, and ultra-fine bubbles may be generated only by the second ultra-fine bubble generator 26B.

As shown in FIG. 9, which is a cross-sectional view perpendicular to the central axis of the miniaturization block 128, two first eccentric supply paths 131 of the miniaturization block 128 are formed so as to communicate with one end of the processing channel . there is These two first eccentric supply channels 131 are arranged point-symmetrically with respect to the center of the processing channel 130 . These first eccentric supply channels 131 extend generally in the radial direction of the miniaturization block 128, form inlet openings 131a on the outer peripheral surface of the miniaturization block 128, and discharge apertures 131b on the inner peripheral surface of the processing channel 130. forming These first eccentric supply passages 131 have a circular cross section and are formed so that the diameter decreases from the inflow opening 131a toward the discharge opening 131b. The discharge opening 131b of the first eccentric supply channel 131 is arranged at a position eccentric with respect to the center of the processing channel 130 when viewed in the axial direction of the processing channel 130 . Here, in FIG. 8, the second eccentric supply path 132 shows the shape of a vertical cross section along the central axis of the second eccentric supply path 132, and a plane passing through the central axis of the fine block 128 is the second It does not show how the eccentric feed line 132 has been cut.

As shown in FIG. 10, which is a cross-sectional view perpendicular to the central axis of the miniaturization block 128, the second eccentric supply path 132 of the miniaturization block 128 communicates with substantially the center of the processing channel 130 in the longitudinal direction. Two are formed. These two second eccentric supply channels 132 are arranged point-symmetrically with respect to the center of the processing channel 130 . These second eccentric supply channels 132 extend generally in the radial direction of the miniaturization block 128 , form inlet openings 132 a on the outer peripheral surface of the miniaturization block 128 , and discharge openings 132 b on the inner peripheral surface of the processing channel 130 . forming 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 channel 132 is arranged at a position eccentric with respect to the center of the processing channel 130 when viewed in the axial direction of the processing channel 130 . The ejection opening 132 b of the second eccentric supply path 132 is eccentrically opposite to the ejection opening 131 b of the first eccentric supply path 131 with respect to the central axis of the processing channel 130 . The first eccentric supply path 131 and the second eccentric supply path 132 of the refinement block 128 are arranged so as to form an angle of 90° with each other when viewed in the axial direction of the refinement block 128 .

The ultra-fine bubble generator 126 configured as described above operates as follows. First, a mixed fluid of water and air is introduced into casing 140 through 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 through the inlet openings 131a and 132a on the outer surface of the atomization block 128 . The mixed fluid guided to the first eccentric supply path 131 is discharged from the discharge opening 131 b into the processing channel 130 to form a swirling flow within the processing channel 130 . A stable swirling flow is formed in the processing channel 130 by arranging the discharge opening 131 b of the first eccentric supply channel 131 at a position eccentric with respect to the center of the processing channel 130 . The mixed fluid guided into the processing channel 130 from the first eccentric supply channel 131 in this way becomes a swirling flow and flows from one end of the processing channel 130 to the other end. Also, the mixed fluid guided to the second eccentric supply path 132 is discharged into the processing flow path 130 from the discharge opening 132b. The discharge opening 132b of the second eccentric supply path 132 is arranged at an eccentric position with respect to the central axis of the processing flow path 130, and is eccentric on the opposite side of the discharge opening 131b of the first eccentric supply path 131. Thus, a swirl flow is formed in the opposite direction to the swirl flow that flows through the processing channel 130 . The swirling flow of the mixed fluid discharged from the discharge opening 132 b of the second eccentric supply passage 132 collides with the swirling flow flowing from the first eccentric supply passage 131 . As a result, the gases of the mixed fluid are effectively atomized to generate ultra-nanobubbles. The water containing the ultra-nanobubbles of air thus generated flows toward the other end of the processing channel 130 and is discharged from the ultra-fine bubble generator 126 through the discharge pipe 42 .

A gas tank 124 that stores air is connected to the upstream side of the mixed air amount adjustment valve 127 . This gas tank 124 is preferably provided with a purifying device for purifying the air sucked from the atmosphere.

The downstream side of the suction pump 121 is connected to the ultra-fine bubble generator 26 that refines the air of the mixed fluid to form ultra-fine bubbles. Instead of the ultra-fine bubble generator 26, a modified ultra-fine bubble generator 126 may be connected. A first liquid pressure sensor 141 is provided between the suction pump 121 and the ultra-fine bubble generator 26 to measure the liquid pressure of the fluid led to the ultra-fine bubble generator 26 .

A gas-liquid separator 125 is connected to the downstream side of the cascade pump 123 to separate surplus air remaining without being added to water from water containing ultra-fine bubbles. The air separated by the gas-liquid separator 125 is returned to the gas tank 124 , while the water containing the ultra-fine bubbles is returned to the water tank 2 . Here, as the first pump of the bubble water production device 103, a positive displacement pump such as a land pump may be used in addition to the submersible pump. As the second pump, a pump other than the cascade pump may be used, but a centrifugal pump is preferably used.

In the bubble water production device 103 of this modified example, the air is led to the bubble water tank 2 by adjusting the opening of the mixed air amount adjustment valve 127 and the discharge flow rate or discharge pressure of the suction pump 121 and the cascade pump 123 . The particle size and concentration of ultra-fine bubbles can be adjusted.

In addition, this bubble water production device 103 measures the concentration of ultra-fine bubbles in the water in the bubble water tank 2, and based on this measured value, the discharge amounts of the suction pump 121 and cascade pump 123, and the mixed air amount adjustment valve By adjusting the opening of 127, the density of the ultra-fine bubbles in the bubble water tank 2 can be adjusted.

The bubble water production device 103 is provided with a second control device, which controls the opening of the mixed air amount adjustment valve 127 and the discharge flow rate or discharge rate of the fluid by the suction pump 121 and the cascade pump 123. The pressure may be controlled to adjust the particle size and concentration of the ultra-fine bubbles in the bubble water tank 2 .

For example, in order to reduce the diameter of the bubbles contained in the fluid in the bubble water tank 2, the opening degree of the mixed air amount adjustment valve 127 is lowered to reduce the amount of air supplied to the ejector 122, and the suction pump 121 and cascade The operation of pump 123 is continued. Fluid in the bubble water tank 2 is sucked by the suction pump 121 and led to the ultra-fine bubble generator 26 , containing bubbles are made fine, 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 generator 26 and the cascade pump 123, the diameter of the bubbles contained in this fluid can be effectively reduced.

Further, for example, in order to increase the concentration of air bubbles contained in the fluid in the bubble water tank 2, the opening degree of the mixed air amount adjustment valve 127 is increased to increase the amount of air supplied to the ejector 122, and the suction pump 121 and Cascade pump 123 continues to operate. The fluid in the bubble water tank 2 is sucked by the suction pump 121 and partly led to the ejector 122 to add air. Also, the other part is led from the suction pump 121 to the ultra-fine bubble generator 26 . Bubbles in the fluid are micronized by the ultra-fine bubble generator 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 ultra-fine bubble generator 26 and the cascade pump 123, the concentration of air bubbles contained in this fluid can be effectively increased.

The ultra-fine bubble generator 26 of the bubble water generator 103 has a pressure of 4 MPa or more and 6 MPa or less between the upstream side and the downstream side, that is, between the pressure of the fluid in the supply pipe 41 and the pressure of the fluid in 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 . In this case, the pressure of the fluid in the supply pipe 41 is adjusted higher than the pressure of the fluid in the discharge pipe 42 . Thus, by creating 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 generator 26, the ultra-fine bubble generator 26 stably produces water containing ultra-fine bubbles. can be manufactured.

In this manner, the modified bubble water production device 103 can stably form ultra-fine bubbles of 50 to 70 nm. Further, the bubble water production device 103 may produce water containing ultra-fine bubbles of oxygen or hydrogen in addition to air. When producing water containing ultra-fine bubbles of oxygen and hydrogen, excess oxygen and hydrogen that have not been added to the water are separated by the gas-liquid separator 125 and returned to the gas tank 124, whereby oxygen and hydrogen are separated. is prevented from leaking to the outside of the bubble water production device 103 . Therefore, when producing water containing ultra-fine bubbles of oxygen or hydrogen, it is possible to effectively prevent inconveniences such as fire caused by leakage of oxygen or hydrogen.

In the above embodiment, the miniaturization block 28 of the ultra-fine bubble generator 26 has the first swirl chamber 31 and the second swirl chamber 33 as swirl flow forming units, but the number is not limited to two. It may have a swirling flow forming part. Further, the miniaturization block 128 of the ultra-fine bubble generator 126 has the first eccentric supply path 131 and the second eccentric supply path 132 as the swirling flow forming section, but the number of swirls is not limited to two, and may be three or more. You may have a flow formation part.

In the above embodiment, egg-laying hens were fed with water containing ultra-fine bubbles of air. good too. In addition to water, slightly acidic electrolyzed water or drinking water obtained by adding ultra-fine bubbles to water containing various other components may be supplied. Both when using water containing ultra-fine hydrogen bubbles and when using water containing ultra-fine oxygen bubbles, the effect of accelerating the start of egg laying in chickens and the effect of improving egg productivity. was confirmed. In addition, even when slightly acidic electrolyzed water was used, it was confirmed that the effect of advancing the start time of egg laying in chickens and the effect of improving the productivity of chicken eggs were obtained.

(Test 1)
In Test 1, the number of eggs collected and the start date of egg laying were tested. As test subjects, 40 120-day-old Boris Brown egg-laying hens were divided into 4 groups of 10 chickens each, fed the following drinking water, and reared flat.
Test group (1): groundwater test group (2): air ultra-fine bubble water test group (3): plant extract mixed fermentation liquid diluted water test group (4): test group (2) and plant extract mixture Mixed Water for Fermentation Liquid As the plant extract mixture fermentation liquid for the test groups (3) and (4), T.K. T.S Ecofarm Co., Ltd. S-minetase was used. Test group (3) was prepared by diluting the stock solution of minetase with 500-fold groundwater. Test group (4) was prepared by diluting the minetase stock solution with 500-fold air ultra-fine bubble water.

FIG. 12 is a graph showing the cumulative number of laid eggs from 120 days old when feeding of drinking water was started to 148 days old. The number of days required from the age of 120 days to the start of egg laying was 25 days for test group (1), which is a conventional group, while it was 11 days for test groups (2) and (4). In this way, by using the mixed water of the ultra-fine air bubble water and the mixed water of the ultra-fine air bubble water and the plant extract mixture fermentation liquid as drinking water, the start of egg laying by egg-laying hens can be shortened by 14 days. confirmed. On the 39th day after the start of feeding of drinking water, the total egg production at 159 days of age was 1.63 times higher in test group (2) than in test group (1), Test group (3) was 0.97 times and test group (4) was 1.68 times. In this way, by using the mixed water of the ultra-fine air bubble water and the mixed water of the ultra-fine air bubble water and the plant extract mixed fermented liquid as drinking water, the spawning period can be advanced, and as a result, It can be said that the egg collection amount can be increased in the entire egg collection period.

(Test 2)
In Test 2, the influence of feed on egg production and egg size was examined when ultra-fine air bubble water was fed. As test subjects, 8,000 Boris Brown egg-laying hens aged between 120 days and 600 days were fed with the ultra-fine air bubble water described above and fed with CP 16% feed. By alternately setting the period of giving Of the 8000 laying hens, 2000 are 120-240 days old, 2000 are 240-360 days old, 2000 are 360-480 days old and 2000 are 480-600 days old. . Egg-laying hens were reared in high-floor poultry houses.

Table 1 shows the results of Test 2. The first period of the period is from day 1 to 10 from the start of the study, the second period is from 131 to 138 days, the third period is from 139 to 179 days, and the fourth period is from 180 to 180 days. 204 days. In Table 1, MS is an egg weighing 52 g or more and less than 58 g, M is an egg weighing 58 g or more and less than 64 g, L is an egg weighing 64 g or more and less than 70 g, 2L is an egg weighing 70 g or more and less than 76 g, A large egg is a chicken egg weighing 76 g or more. The 1st and 2nd periods are excluded from the study because they contain a large proportion of hens that have not laid eggs among 120-day-old hens. In the third period, 95.2% of all eggs were M-sized or larger, although the feed was 16% CP. Therefore, by using feed containing 16% CP, which is less expensive than 18% CP, it is possible to produce a high proportion of eggs of a size that can be distributed, thereby effectively reducing feed costs. In addition, in the third period, more eggs of M size and L size, which are in higher demand than other sizes, could be produced than in the fourth period. Therefore, using an inexpensive 16% CP feed, more M and L size eggs, which are in great demand, can be produced than using a 18% CP feed, so the efficiency of egg production can be effectively increased.

(Test 3)
In Test 3, a test was conducted on the difference in egg size depending on the presence or absence of ultra-fine bubbles in the air of the drinking water. As test subjects, 150-day-old Boris Brown egg-laying hens were fed test group (5) with drinking water containing the above-described ultra-fine air bubbles and drinking water containing no ultra-fine air bubbles. A test group (6) was set up and fed the same 18% CP diet. Both test group (5) and test group (6) raised 8000 egg-laying hens each. As a result, the test group (5) had 200 large eggs out of a total of 5700 eggs laid per day. In the test group (6), 100 large eggs were produced out of 5000 eggs laid daily. Thus, by feeding drinking water containing ultra-fine bubbles, it is possible to effectively produce large eggs.
