Description

Feeding method and feeding sheet for chicks

The present invention relates to a method for feeding (bringing) “chicken (also referred to as“ chick ”” in the present specification and claims) ”in the breeding of poultry such as chickens, and a feeding sheet used therefor.

In poultry farming, for example for layering (chicken) and broilers (meat chickens), the stage of the chicks, specifically, chicks (from the hatchery to the chicks to enter the chicken farm) For example, how much food is eaten during the period up to about 7 days later and how it grows during that period greatly affects the subsequent increase in body weight (weight gain) and the decrease in the mortality rate. In other words, chicks that have eaten a lot of food for about 7 days after entering the chicks are known to grow smoothly thereafter.
Therefore, it is extremely important for producers engaged in poultry farming so that the chicks eat a lot of food between about 7 days after the introduction.

In a conventional poultry house, raw materials such as sawdust (wood waste) were laid on the floor, and chickens were raised on the chicks. At that time, in the case of “chicks” that have just entered the chicks, even if a feeding box or the like is installed, there is little habit of going to the feeding box and eating, and there is a habit of eating nearby food that has fallen exclusively on the floor.
However, it is difficult to find food mixed in sawdust in the case of chicks, when the food is spread on sawdust and so on. For this reason, it is difficult to find food mixed in sawdust. Difficult to eat.

In view of this situation, when raising chicks, laying a paper sheet (feeding sheet) on sawdust, etc., and feeding and feeding the chicks on the feeding sheet Has been proposed (see Patent Document 1).
In this case, chicks are easy to find food because the food is always on the feeding sheet and is not buried in the sawdust.
However, even when a feeding sheet is laid on the floor and the food is scattered on the feeding sheet, it has been found that chicks do not always eat enough food.

In view of the above situation, the present inventor has made the invention described in Patent Document 2 in order to solve such a technical problem.
In other words, even if rearing with a conventional feeding sheet spread, there is doubt that the food scattered on the feeding sheet will not be eaten enough, and the color of the feeding sheet is changed variously. And the intake of food were observed over a predetermined period. As a result of observation, it was found that if the color of the feeding sheet is different from the color of the bait so that it can be visually recognized, even the chicks who have just entered the chicks eat well.
An international patent application is filed for an invention based on the discovered event, and a determination of “inventive step” is made in an international preliminary examination report relating to the subsequent international preliminary examination. Finally, the patent is transferred to Japan (Patent No. 5855089). No.) was made.

Japanese Patent Application Laid-Open No. 2005-80593. International publication number WO2012 / 132392.

The present inventor continued research on whether chicks can eat more food and grow more than 7 days after entering the chicks.

Under such circumstances, the present invention provides a feeding (breeding) method for a chick bird that feeds and grows more during the period up to about 7 days after entering the chick, and a feeding method suitable for carrying out this method. The purpose is to provide a sheet.

In the feeding method of the chick bird according to the present invention, a material such as sawdust or cut straw or rice husk is laid on the floor of the breeding area, and a feeding sheet having a lightness different from that of the food is laid thereon. In the feeding method of chicks that spreads food on the sheet and grows chicks,
As the feeding sheet, a feeding sheet provided with a portion with a low lightness color in the ground color that becomes a high lightness portion is laid on the material, and then the food is sprinkled on the food. It is characterized by that.

According to the feeding method for chicks configured as described above, the inside of a poultry house with a roof is generally dark, but even in such a case, the whole feeding sheet is caused by the high brightness of the ground color of the feeding sheet. Relatively bright.
For this reason, chicks are more active than conventional feeding sheets, resulting in an increase in the amount of food consumed.
In addition, because the part with a low-lightness color is arranged, the absorption of radiant heat is enhanced even when heated by a Bruder (Bruder: poultry house heating device) in winter and cold regions. The temperature on the feeding sheet surface can be brought to the predetermined temperature more quickly and with low energy.
In addition, when there is a portion with a low-lightness color, when the child takes a rest, he prefers a dark place, so this portion can give the chick a sense of security. Moreover, since the contrast with a bait can be strengthened in the part with the color with the said low brightness, it becomes easy to find a bait also for a chick bird with weak visual acuity. For this reason, the amount to eat further increases.
Furthermore, if the color of the food is set lower by at least “2” in the Munsell color system than the high-lightness portion, the chick can easily find the food even in the high-lightness portion.
In this way, in addition to the reason that the food is easy to see due to the difference in color (lightness) between the food and the feeding sheet, in the case of chicks, they prefer shade when resting. For the same reason, it is presumed that the black or dark gray part may provide a sense of security to the chick in a mental aspect.
In addition, when the portion with the low lightness color is black or dark gray, a chick bird generally having a yellow color is easily noticeable in the portion. For this reason, it is easy for the producer (keeper) to grasp the movement of the chick bird, and therefore, it becomes easy to find and protect or isolate the weak chick bird. As a result, the mortality rate of chicks can be reduced, and it is also preferable in that the spread of epidemics can be prevented.
In addition, every time a chick walks on the feeding sheet, as in the present invention, a material such as sawdust or cut straw is laid on the floor of the breeding area and a feeding sheet is laid on it. Then, a loud “gutter” sound is generated between the material such as sawdust and cut cocoon that tends to collapse and the feeding sheet deformed by the weight of the chick.
As a result of observation, it was found that, as a characteristic of the chick bird, other chicks responded to the sound of the “gas” and all the chicks started to move actively.
As a result, the stimulation by the “sound” increases the amount of movement of the chicks and increases the amount of food to eat.

In the feeding method of the chick bird, the feeding sheet is preferably a sheet formed with a planar pattern in which a portion with a low lightness color is arranged in a stepping stone shape in a ground color that becomes the high lightness portion. . That is, a portion colored in low lightness arranged in a stepping stone shape is considered to be a shadow of itself or another chick bird and is stimulated, and the chick bird receiving the stimulus moves actively.

In the feeding method of the chick bird, if the corner of the feeding sheet, which is arranged in a stepping stone shape and colored in a low brightness, has a round shape, the chick bird feels secure because of its shape. This is a more preferable configuration.

Furthermore, in the feeding method of the chick bird, when the area ratio of the lightly colored portion disposed in the high lightness portion is 15% to 40%, the lightness is high. It is preferable in that the function and effect obtained from the part and the colored part with low brightness act in a well-balanced manner, and the function and effect can be obtained remarkably as a whole.

Further, in the feeding method of the chick bird, when the ground color of the portion with high lightness is off-white, beige, or yellow, and the portion with the color with low lightness is black or dark gray, these colors When using a bait having a color different from the lightness, for example, it is also preferable to increase the lightness of a portion having a high lightness by “2” or higher in the Munsell color system compared to the lightness of the bait. In the Munsell color system, it is preferable to increase the lightness by “2” or more because it is easy to identify the bait even in the high lightness portion. Also, when the water supply is arranged, the brightness of the water supply differs by “2” or more in the Munsell color system as compared with the lightness of the high lightness portion and the low lightness colored portion as in the bait. It is preferable that the lightness is red, yellow or orange so that it is easily noticeable.

Further, in the feeding method of the chicks, if some of the lightly colored parts arranged in the stepping stone shape have an area approximately equal to the projected area of the chicks one week after entering the chick, The part is thought to be a shadow of other chicks, and the chicks are stimulated by this and become active.

Further, in the feeding method of the chick bird, as a coloring agent for coloring in order to form the colored portion having a low lightness, a charcoal or a coloring agent approved for use in the Food Sanitation Law is used, Even if a chick bird eats a feeding sheet, it is harmless and does not adversely affect when it is shipped as chicken after growth.

In addition, the feeding sheet according to the present invention lays a material such as sawdust or cut straw or rice husk on the floor of the breeding area, spreads a feeding sheet on the material, and disperses the food on the feeding sheet. It is a feeding sheet used for the method of growing and growing chicks.
When the feeding sheet is a sheet provided with a portion with a low-lightness color in a ground color that is a high-lightness portion, the feeding sheet used for the feeding method of the chicks can be realized.

In the feeding sheet of the chick bird, the ground color to be the high brightness portion is off-white or beige, or yellow, and the low-lightness colored portion is disposed in a stepping stone shape in the ground color, In addition, it is preferable that some of the colored portions with low lightness have an area substantially equal to the projected area (projected area on the feeding sheet) of the chicks in the first week.

In the feeding sheet of the chick bird, the paper having a coarse fiber structure is separated so that the feeding sheet is separated in about 1 to 10 days, preferably in about 2 to 4 days, when the chicks raised on it are stepped on. If it is comprised, it will become a preferable structure.

In the feeding sheet for chicks, when the feeding sheet is made of waste paper having a weight of 30 to 55 g per square meter, it is easy to spread in use and has appropriate durability and water absorption. Moreover, it is preferable at the point which can supply cheaply economically.

In the feeding sheet of the chick bird, the period during which the feeding sheet is separated is the perforation or embossing hole in which the feeding sheet is perforated (perforated) or embossed (unevened). The size of the protrusions and the interval between the holes or protrusions and the perforation lines (lines formed by a plurality of holes (needle holes) in a line) or the lines of protrusions (lines formed by a plurality of protrusions in a line) ) May be adjusted by either one or both of the intervals. In such a configuration, even when the durability of the waste paper itself exceeds the desired period of “separation”, the period of “separation” can be freely set by appropriately forming the perforation or embossing. .
Further, the urine of the chick bird can be passed downward from each hole of the perforation and the embossed recess, and the ventilation property under the feeding sheet can be obtained.
In this specification and claims, the term “perforation” refers to a group of perforated needle holes, and is not necessarily used in the sense that it is limited to those formed in one or more rows. .

In addition, when the perforation line or the line of the convex portion is provided side by side with a predetermined interval in the longitudinal direction of the sheet, the feeding sheet is set by appropriately setting the interval. It is possible to realize a configuration in which the “separated” period can be adjusted.

Further, when the perforation line or the convex line is provided side by side in a direction having an angle of intersection with the longitudinal direction of the sheet, the feeding is performed by changing the interval. It is possible to realize a configuration in which the period during which the sheet is “separated” is adjustable. Moreover, even if the sheet is pulled in the longitudinal direction, it is difficult to be easily torn.

In the bait sheet, it is preferable that the colored portion of the bait sheet with a light color is lower by 2 or more in the Munsell color system than the bait value, and in particular, the color with the low lightness is applied. When the portion is black or dark gray (specifically, black or gray belonging to the lightness “1” to “3” of the Munsell color system), which is “2” or more lower than the bait color in the Munsell color system It was found that a large amount of food intake resulted in remarkable breeding results. Presumably, in addition to the reason that “the food is easy to see” due to the difference in color between the food and the feeding sheet, the same reason as this because the chicks prefer shade when resting Therefore, it is presumed that in the case of a black or dark gray background color, the chick bird is reassured from a mental point of view.
In addition, when a part of the feeding sheet is black or dark gray, it is easy to notice when a yellow chick is on it, so it is easy for the producer (keeper) to grasp the movement of the chick. Can be easily detected and protected or isolated. For this reason, it is preferable also in the point that the death rate of a chick can be reduced and the infection of a plague can be prevented beforehand.
Further, it is also preferable that the lightness portion of the feeding sheet is higher by “2” or higher in the Munsell color system than the lightness of the bait, in particular, “2” or higher in the Munsell color system is higher than the bait. When it is white, beige, or yellow, a preferable result can be obtained for the same reason as described above.

The feeding sheet is a feeding sheet laid on the floor of a chicken house in the breeding of chicks, and the color of the colored portion of the feeding sheet with a low color is preferably different from the color of the food. It becomes.

If the color of the low-lightness portion of the bait sheet is black or dark gray, it will be easy to find the bait, and as a result, the amount of bait will be increased.

And, as the feeding sheet, when a predetermined period, that is, when a predetermined use period of the feeding sheet has elapsed, the feeding sheet is stepped on the sheet or by absorbing feces or the like, or both, It is desirable to obtain a finely crushed state.
As such a feeding sheet, it is preferable to use waste paper (recycled paper) mainly made of corrugated cardboard or newspaper, from the viewpoint of recycling environment.

According to the feeding method and feeding sheet of a chick bird according to the present invention configured as described above, a sheet having a planar pattern composed of a ground color having a specific brightness and a colored portion having a low brightness is used as a feeding sheet. By simply using it, a remarkable effect that cannot be obtained with a conventional feeding sheet, that is, the intake and survival rate of the chick bird are remarkably increased, and efficient and stable growth of the chick bird can be obtained. Since the consumption of broilers and the like is enormous when viewed on a global scale, the economic effect contributed by the present invention is great.

It is the perspective view which showed notionally the state currently raised on the feeding sheet | seat concerning one Embodiment of this invention. In FIG. 1, the plane pattern and the perforation are omitted.

Hereinafter, the feeding method and feeding sheet for chicks according to the embodiment of the present invention will be specifically described.

(Embodiment)
1 and 2, reference numeral 1 denotes a feeding sheet for raising poultry (chicks in this embodiment). The feeding sheet 1 is placed on a material 6 such as straw or sawdust laid on the floor 3 of the poultry house. Laying and spreading the feed 2 on the feeding sheet 1, and breeding the chicks 5 that have entered the chick are raised on the feeding sheet 1.
As the feeding sheet 1, the cost can be kept low, the absorbency of liquid such as manure and the high permeability and breathability, and the point of being easily mixed with the material after use and returning to the soil. And used paper (recycled paper) is used. Such waste paper is mainly made of cardboard or newspaper.

As shown in FIGS. 3 to 5, the feeding sheet 1 is provided with a portion 1B with a low lightness color in a ground color portion consisting of a portion 1A with a high lightness background color. The high brightness portion 1A is composed of yellow (or beige or off-white) having a brightness of “7” to “9” of the Munsell color system, for example. The low-brightness colored portion 1B is composed of, for example, dark gray (substantially black) having a lightness of “2” to “3” in the Munsell color system.
In the case of this embodiment, the feeding sheet 1 has a portion 1A with a high lightness of the ground color colored in yellow with a lightness of “7” in the Munsell color system close to the color of a chick bird. As a portion 1B with a low color, a dark gray portion having a lightness of about “3” of the Munsell color system is arranged in a stepping stone shape.

As the stepping stone shape, as shown in FIG. 3, dark gray portions having a circular shape in a plan view (one form of a planar shape without corners) are arranged at appropriate intervals. In this embodiment, the circular dark gray portion, that is, the portion 1B colored with low lightness, is formed by a circle having a size approximately equal to the projected area of a chick bird of about one week, that is, a diameter of about 7 cm. Has been.

Further, in the case of this embodiment, a plurality of the lightly colored portions 1B are arranged at intervals of about 17 cm in the longitudinal direction of the feeding sheet 1 and are arranged at intervals of about 9 cm in the width direction. . Further, it is formed with a deviation of about 8.5 cm from the adjacent row.
However, the interval is not limited to the numerical value, and may be arranged so that the interval is slightly smaller or larger. That is, the low-brightness colored portions 1B may be arranged at an interval of about 10 cm to 19 cm in the longitudinal direction and may be arranged at an interval of about 7 cm to 11 cm in the width direction. These intervals may be determined as appropriate depending on the type of chicken, the growth process (time), the brightness of the chicken house, and the like.

As described above, if the portion 1B colored with low lightness has a shape with no corners such as a circle or an ellipse of the size described above, the chicks are psychologically relieved. Further, the inventor has a tendency that the portion 1B colored in low lightness arranged in a stepping stone is stimulated by thinking that the chick bird is his own shadow or other chicks in the vicinity, and moves more actively. From the observation of

By the way, the area ratio of the portion 1B to which the low-lightness-colored portion 1B is disposed is about 30% to about 35% with respect to the ground color which is the high-lightness portion 1A. However, in practice, the area ratio may be about 10% to 45%, but the area ratio is preferably about 15% to 40% because of psychological effects on chicks. In particular, the area ratio is more preferably about 30 percent to about 35 percent.
In FIG. 1, the pattern resulting from the stepped stone-like portion 1 </ b> B having a low brightness is omitted from the feeding sheet. Moreover, it is actually raised in a poultry house using a larger space than shown in FIG.
Moreover, in FIG. 1, the code | symbol 10 represents a water supply device, and this water supply device 10 is a device in which the water for the chick bird 5 to supply water is stored. The water supply 10 is preferably red, yellow, or orange having a lightness comparable to that of the bait 2 that is easy to find for chicks 5 with low vision.

By the way, in FIG. 3, the part 1B which attached | subjected the color of the low lightness of the circle | round | yen with the same magnitude | size (area) as a stepping stone shape is attached | subjected, However, as another embodiment, FIG. As illustrated, a plurality of types (two types in this embodiment) having different sizes (areas) may be used. That is, in this embodiment, as the stepping stone-like arrangement, as shown in FIGS. 4 and 5, the lightness of about 70Φ (diameter is about 70 mm) having an area substantially equal to the shadow of the chick bird in the first week. A low-colored portion 1Ba, a smaller-area portion 1Bb consisting of about half the diameter (diameter is about 35Φ), and a further smaller portion consisting of about 40 percent of the diameter (diameter is about 13.5Φ). You may be comprised from the part 1Bc of an area. Two or more different sizes may be arranged.

In addition to the shapes shown in FIGS. 3 to 5, the shape of the portion 1B colored with low brightness may be an elliptical shape or other non-circular shape. However, it is preferable that the portion 1B colored with low lightness is formed in a round shape without corners. In other words, it has been observed from observation that chicks including human infants are more interested in shapes without corners than those with corners. In addition, the round shape without corners is presumed to give the chick a sense of security.
The stepped stone-like portion 1B having a low lightness color as described above may be formed with the low lightness color in a so-called “solid coating” state, or a black or dark gray line. It may be obtained by hatching in a pattern.
Further, in the plane pattern, a stepped stone-like portion 1B with a low lightness has a so-called “blur” shape (gradation) in which the lightness gradually increases from the center toward the outer edge side. Also good.

Further, the feeding sheet 1 has a very small space (hole) inside the tissue because the fiber structure of the paper is relatively coarse. For this reason, it absorbs feces and urine of chicks and allows liquid to easily penetrate downward. As a result, when the chick bird steps on the feeding sheet 1 from above, if it is used for a predetermined period, for example, about 1 day (24 hours) to 10 days, the feeding sheet 1 is separated.
The feeding sheet 1 is made of used paper that is recycled from corrugated cardboard, newspaper, or the like as a main raw material, in which the fiber structure of the paper is “coarse” and the mixing ratio of the binder (glue) that connects the fiber structures is small. ing.
Moreover, the feeding sheet | seat 1 concerning this embodiment is wound by roll shape, and cuts and uses it as needed. 3 to 5, the dimension W described in the drawings indicates the effective width of the feeding sheet 1 wound in a roll shape, and the plane pattern is formed in the effective width W. Moreover, the dimension Wb described in the figure shows the overlap margin when a plurality of feeding sheets 1 are arranged in parallel in the width direction. In this embodiment, W is 800 mm and Wb is 150 mm. However, these dimensions are not limited to the dimensions of the above embodiment, and may be set as appropriate.

Moreover, as one embodiment, as shown in FIGS. 6 and 7, the feeding sheet 1 is separated in the desired period (for example, 3 days (72 hours) or 1 day (24 hours)). In order to do so, a line group of perforations 1d composed of a hole (needle hole) 1t group of a predetermined size is formed with a predetermined interval.
That is, in the feeding sheet 1 of this embodiment shown in FIG. 6, the size of each hole 1t of the perforation 1d is substantially 0 so that the feeding sheet 1 becomes “separated” in about 3 days (72 hours). A plurality of lines (line group) formed in 0.03 mm are juxtaposed. In the present embodiment, the interval between the hole 1t formed along the line direction of the perforation 1d (“X direction” in FIG. 6) and the adjacent hole 1t is a predetermined interval (for example, approximately 0.5 mm). (Interval). Further, the interval between lines adjacent to the line is formed at a predetermined interval (for example, 40 mm).
Further, when it is desired to shorten the period of “separated”, as shown in FIG. 7, the direction (“Y direction” in FIG. 7) forms an angle of intersection with one line direction (“X1 direction”) of the perforation 1d. It is desirable to arrange the line L group of the perforation 1d. That is, by forming the line L groups in a plurality of directions in this way, it is possible to realize a configuration in which the breaking strength of the feeding sheet 1 is weakened and “separated” in a short period of time.
As described above, when the perforation 1d is formed so as to cross in two directions having a predetermined angle with respect to the longitudinal direction (rolling direction) as shown in FIG. Even when the feeding sheet 1 is pulled in the longitudinal direction (see the arrow X direction in FIG. 6) when laying on the sheet, it is preferable that the perforation 1d is not easily cut in the direction perpendicular to the longitudinal direction.
In addition, although not shown, by forming the perforation 1 in two or more directions, for example, three directions, four directions or more directions, the period of “separation” can be adjusted to be shorter. it can.
It can also be shortened by increasing the perforated area of the hole 1t.
Although not shown, when the line L of the perforation 1d is formed in a direction perpendicular to the longitudinal direction of the bait sheet 1 (roll winding direction: see the “X” direction in FIG. 6), the bait This is a preferable configuration in that the sheet 1 is easily cut when it is cut into a predetermined length.
Further, by appropriately setting the size of the hole 1t of the perforation 1d, the interval between the hole 1t and the hole 1t of the perforation 1d, or the interval (distance) between the line L of the perforation 1d and the adjacent line L, The period during which the feeding sheet 1 is “separated” can be adjusted to be arbitrarily short or long.
By the way, in place of the perforations, as shown in FIGS. 8A and 8B, the feeding sheet 1 is embossed to form the concave portions 1w and the convex portions 1v, thereby obtaining the desired period (for example, 3 days (72 hours) or 1 day (24 hours)) may be configured to “separate”. In particular, in the embossing according to the present embodiment, in order to further shorten the period during which the “separation” occurs, embossing in which a torn part is formed in a part of a circular corner 1k of the convex portion 1v in plan view is performed. Has been done.
When the embossing is performed, a state in which urine collects and accumulates in the recess 1w is formed, so that the period of “separation” can be effectively shortened. For example, in the state where the embossing is not formed, it has been confirmed by an experiment of the present inventor that the period of “separated” in 10 days becomes “separated” in one day by applying embossing. Yes. Moreover, when the bait 2 (see FIGS. 1 and 2) enters the embossed recess 1w, the bait becomes difficult to move from that position, so that the chick bird 5 (see FIGS. 1 and 2) can easily pinch the bait 2. Moreover, since the feed 2 becomes difficult to move, it is preferable in that the feed 2 is not biased to a part of the feeding sheet 1 due to the movement of the chick bird 5 or the like. In FIG. 8A, the arrow X indicates the longitudinal direction of the feeding sheet 1.

By the way, in this embodiment, the feeding sheet 1 is waste paper as described above, and has been rolled into a weight of about 40 g to about 46 g per square meter and about 0.09 mm in thickness. It is constituted by.
However, the feeding sheet 1 may have a weight of about 30 g to about 55 g per square meter, and may have a thickness of about 0.07 mm to 0.13 mm. .
In addition, the feeding sheet 1 is preferably 100% of waste paper for the above-mentioned reasons, but a small amount of virgin pulp or fibrous material is mixed when the tensile strength is increased or when it is desired to lengthen the period of “separation”. You may use what was done.

By the way, in this embodiment, the bait 2 is qualitatively generally used for breeding chicks, and in terms of color (particularly lightness among colors), the lightness of the Munsell color system is approximately “5”. Something red or orange is used. That is, in the Munsell color system, even if the bait 2 is sown on either the high-lightness portion 1A or the low-lightness-colored portion 1B, the lightness between these portions and the lightness of the bait 2 There is a difference of about “2” or more in brightness, and the chick bird 5 with weak eyesight can easily find the food 2.

In addition, in this embodiment, charcoal is used as a colorant and edible paste is used as the binder in order to obtain a feeding sheet 1 having a portion 1B colored with low brightness. However, in the present invention, the colorant is not limited to charcoal, and other colorants having the same coloring effect and approved for use in the Food Sanitation Law may be used. Similarly, the binder is not limited to the edible paste as long as it is permitted by the Food Sanitation Law. Note that the binder is not necessarily used.

Then, the feeding sheet 1 having a flat pattern in which the portion 1B with a low lightness color in the ground color of the high lightness portion 1A is arranged in a stepping stone shape is as shown in FIG. It is laid on a material 6 such as sawdust (or cut straw or rice husk, or a mixture thereof) laid on the floor 3 to a substantially uniform thickness. Then, on the feeding sheet 1, the food 2 is dispersed and the chick bird 5 is bred.
At this time, in the portion 1B colored with low lightness, since the lightness difference from the food is large, the chick bird 5 can easily find the food 2. In addition, as in this embodiment, when there is a sufficient lightness difference (for example, a lightness difference “2” or more) in the Munsell color system even in the high lightness portion 1A with the bait 2, such lightness Even in the high portion 1 </ b> A, the chick bird 5 can easily find the food 2.
Also, as in this example, `` On the floor of the breeding area, a material such as sawdust or cut straw is laid and a feeding sheet is laid on it, '' each time a chick walks on the feeding sheet, A loud rustling sound is produced.
Other chicks react to the sound of “gas” and all chicks start to move around.
As a result, stimulation by “sound” further increases the amount of movement of the chicks and increases the amount of food they eat.

As shown in FIG. 1 or FIG. 2, using the feeding sheet 1 as described above, when raising a chick bird 5, as compared to the case where a chick bird is bred using a commercially available conventional paper sheet, Since the movement of the chick bird 5 becomes active and it becomes easy to find the food, the intake (weight) of the food is remarkably increased, and favorable growth can be obtained in the subsequent breeding. Moreover, since it becomes easy to find the chick bird 5 on the feeding sheet 1, the moribund rate of a chick bird falls.

When the feeding sheet 1 is used for about 1 day (or 2 to 10 days depending on the setting of the feeding sheet 1), the feeding sheet 1 having the above-mentioned paper quality and configuration is placed on the feeding sheet 1 such as feces and urine. When the chick bird 5 etc. walks on it while being absorbed, it will be broken apart. At this time, the perforation 1d is promoted to become the “separated”.
And the destroyed feeding sheet | seat 1 will be in the state mixed in raw materials 6 grade | etc., Such as said sawdust.

Further, when the feeding sheet 1 is used for a predetermined period of time, it is destroyed as described above, so that it is possible to save the trouble of removing the used one and discarding it as in the case of a conventional paper feeding sheet. . That is, in the case of the feeding sheet 1 according to the present embodiment, the feeding sheet 1 is broken and mixed with the raw material 6 such as flour, so that it is not necessary to specifically dispose of the feeding sheet 1 after use.
Therefore, for the poultry farmer, the time and effort for disposal can be saved and the disposal cost becomes unnecessary, and the space for temporarily storing the used feeding sheet 1 before disposal becomes unnecessary.
In particular, as in this embodiment, when a coloring agent recognized in the Food Sanitation Law such as charcoal is used for coloring the feeding sheet 1, it is a harmless substance for the chicks 5. Use of a binder approved by the Food Sanitation Act such as edible glue as a binder (glue) that connects tissues to each other is harmless even if the chick bird 5 eats the feeding sheet 1 It is preferable at this point.

Moreover, according to the feeding method of the feeding sheet 1 and the chick bird 5 according to the present invention, it is possible to shorten the period until the chick grows to the weight necessary for shipping, compared to the case of using the conventional feeding sheet. . For this reason, shipment can be accelerated compared with the past. As a result, the profitability of poultry farming is improved by shipping ahead.
In addition, because the survival rate of chicks can be increased and the mortality rate can be kept low, productivity is improved.
Furthermore, unnecessary work of the poultry farmer can be eliminated.

By the way, the embodiment described above is merely an embodiment of the present invention, and the present invention is not limited to the matters described in the embodiment, and various forms are possible within the scope based on the technical idea of the present invention. It goes without saying that it can be implemented.

The feeding method and feeding sheet for chicks according to the present invention can be used in the field of poultry farming.
