Description

  The present invention relates to an estrus detector for livestock, and more particularly to an estrus detector that is attached to a buttock of a cow and detects the estrus of the cow in order to detect the estrus of the cow.

  Sexually mature and healthy cows repeat estrus of accepting bulls at regular intervals (about 21 days), and natural mating with bulls is carried out during this estrus period. And when a cow is conceived, estrus stops. In recent years, in order to speed up the improvement of livestock, when estrus is found during the estrus period of cows, instead of bulls, artificial insemination has been widely performed.

  Cows ovulate at a predetermined time after estrus, but if they do not fertilize at the appropriate time, they will not fertilize, and if this timing is missed, livestock farmers will not be able to artificially fertilize until the next estrus of cows. Will be wasted and time and money will be wasted. For this reason, it is extremely important for livestock farmers to accurately detect the estrus of cows.

  When a cow is in estrus, in addition to the change in the body that changes in the reproductive organs, the amount of movement to walk around increases, rides on another cow from behind (hereinafter called mounting, sometimes called riding), or Even if it is mounted on another cow, there is a change in behavior that allows it to stand still (hereinafter referred to as standing). For this reason, several methods have been proposed for detecting estrus by detecting such changes in cow behavior.

  For example, to detect the estrus of a cow from the amount of exercise of a cow, a vibration detector such as an acceleration sensor is attached to the neck, abdomen, or leg of an animal such as a cow with a band or the like to measure the number of cows walking. However, there is one that detects estrus by managing the amount of exercise by the number of walks and detecting a sudden increase in the amount of exercise (see Patent Document 1). In order to detect the estrus of the cow from the mounting, a detection sheet in which a coat layer that is peeled off by friction is laminated on the vivid color layer is attached to the buttock of the cow, and the coat layer is peeled off by the mounting and the color layer. In some cases, the estrus is detected by exposing the light (see Patent Document 2).

JP 2001-120097 A (FIGS. 1 and 2) US Pat. No. 6,467,430 (FIGS. 1, 2, and 4)

  However, in the estrus detection disclosed in Patent Document 1 which detects the momentum by the vibration detector, there is a large individual difference between cows, and it is practically difficult to find estrus unless thresholds are set one by one, and this method cannot be used. There were many farmers. Further, in the estrus detection disclosed in Patent Document 2 in which the estrus is detected by exposing the color layer to the sheet-shaped detector attached to the calf's buttocks, the degree of exposure of the color layer is confirmed by visual observation. Since it was judged, it was difficult to judge the degree of estrus, and there was a problem that the time of estrus and subsequent ovulation could be overlooked due to lack of farmers' attention.

  Therefore, the present invention solves the problem of the detection sheet disclosed in Patent Document 2 for detecting the estrus of a cow from mounting, and when the coating layer is peeled off by mounting, a mark that can be easily identified from the outside appears on the display layer. Or cheap livestock that can detect the degree of estrus more reliably by detecting the estrus level by visually observing the change of the mark or using the mark detection device so that the mark disappears from the release coat layer It aims to provide an estrus detector. In addition, a bar code is used for the mark, and the number indicated by the bar code is associated with the individual registration number of the livestock stored in the mark detection device or the farm number, and the individual identification of the estrous cow is used with the mark detection device. It is an object of the present invention to provide an estrus detector for livestock that can be automatically performed.

  The livestock estrus detector of the present invention that achieves the above-mentioned object is a livestock estrus detector that detects estrus by applying it to the buttocks of livestock, the lower surface being a pasting surface, the upper surface being a display layer, and One side of the display layer so that the degree of peeling of the release coat layer can be recognized from the outside, which is coated with a coating to hide the display face and is peeled off from the display face by friction to expose the display face. In addition, at least one mark is printed on at least one of the release coat layer, and the print form of the mark is determined by the degree of release of the release coat layer by mounting other livestock on the livestock with the estrus detector attached. When the change occurs, the estrus state of the livestock can be identified by detecting the change in the degree of exposure or disappearance of the mark visible from the outside of the livestock using visual or electronic equipment. A printing form, an estrus detector livestock, which comprises one of the following forms. (1) There is one type of mark shape, and the larger the distance from the center of the estrus detector to the left / right or front / rear end, the greater the print density of the mark; (2) there are multiple types of mark A mode in which the area of the mark increases as the distance from the center of the estrus detector to the left and right or front and rear ends increases; (3) The distance from the center of the estrus detector to the left and right or front and rear ends increases. A mode in which the area of the printed mark increases rapidly; and (4) a mode in which the mark is a bar code.

  According to the present invention, when the coat layer of the estrus detection sheet affixed to the buttock of the cow is peeled off and the display layer is exposed, a mark that can be easily identified from the outside appears on the display layer, or the mark disappears from the peel coat layer. Thus, the change of the mark can be visually detected or the estrus can be detected more reliably by using a mark detection device. In addition, if a bar code is used for the mark and the number indicated by the bar code is associated with the individual registration number of the livestock stored in the mark detection device or the farm number, the individual identification of the estrous cow is identified by the mark detection device. Can be done automatically using. As a result, estrous checks that are extremely time-consuming can be managed more accurately even at locations away from the cows on the farm, even if they are not near the cows, enabling efficient livestock management and economic Great effect.

  Hereinafter, embodiments of the present invention will be described in detail based on specific examples with reference to the accompanying drawings. Prior to describing the examples of the present invention, Patent Document 2 which is a prerequisite technology of the present invention will be described. The detector described in 1 is briefly described. In this embodiment, a cow is illustrated as an animal for detecting estrus, but the present invention can be similarly applied to other animals that are mounted or standing by estrus.

  FIG. 1A shows the structure of the estrus detector 10 disclosed in Patent Document 2. The estrus detector 10 includes a display layer 12, an adhesive layer 14 is provided on the lower surface of the display layer 12, and a release coat layer (flood coat layer) 16 is provided on the upper surface of the display layer 12. The display layer 12 is colored on the upper surface side so that it can be seen well from a distance. The release coat layer 16 covers the display layer 12 and is peeled off from the display layer 12 by friction when rubbed. The estrus detector 10 before use has liner paper attached to its upper and lower surfaces to protect the adhesive layer 14 and the release coat layer 16. The liner paper is not shown.

  FIG. 1B shows a place where the estrus detector 10 shown in FIG. 1A is attached to the cow 1 and shows the cow 1 viewed from the back. The estrus detector 10 is attached to the cow 1 with an adhesive layer 14 attached to the center of the buttocks 11 of the cow 1. This is because when the cow 1 enters the estrus period, the amount of activity increases and mounting and standing as shown in FIG. 1C are performed. That is, the cow 1 performs a standing that allows another cow 2 to be mounted from behind. Another cow 2 may be a cow or a bull. The peeling coat layer 16 of the estrus detector 10 is peeled off from the display layer 12 by the standing of the cow 1 and the mounting of another cow 2. The amount that the release coat layer 16 is peeled off from the display layer 12 increases as the number of mounting and standing increases.

  FIG. 1D shows the exposed state of the display layer 12 of the estrus detector 10 shown in FIG. 1A when the number of mountings is one. FIG. 1E shows the exposed state of the display layer 12 of the estrus detector 10 shown in FIG. 1A when the number of mountings is 3 to 5, and FIG. 1F shows when the number of mountings is 5 or more. It is a figure which shows the exposure state of the display layer 12 in the estrus detector 10 shown to FIG. 1A. Thus, in the conventional estrus detector 10, the greater the number of mountings, the greater the degree of exposure of the display layer 12 in the estrus detector 10.

  However, since the conventional estrus detector 10 determines the estrus state by visually observing the exposed area (analog amount) of the display layer 12 from the outside, it is difficult to understand the degree of estrus. Therefore, in the present invention, the problem in the conventional estrus detector 10 is solved, and the degree of exposure of the display layer 12 is represented by a digital value so that the degree of estrus can be determined more accurately.

  FIG. 2A shows the structure of the estrus detection sheet 21 of the first embodiment of the livestock estrus detector 20 of the present invention. The estrus detection sheet 21 includes a display layer 12, an adhesive layer 14 is provided on the lower surface of the display layer 12, and a release coat layer (flood coat layer) 16 is provided on the upper surface of the display layer 12. In the estrus detection sheet 21, a large number of color marks 3 that can be seen well from a distance are printed on the upper surface side of the display layer 12. The release coat layer 16 covers the display layer 12 as in the conventional example, and when it is rubbed, it is peeled off from the display layer 12 by friction. Also in this embodiment, illustration of the liner paper for protecting the adhesive layer 14 and the release coat layer 16 is omitted.

  FIG. 2B is a plan view of the display layer 12 of FIG. 2A. A large number of circular marks 3 are printed on the display layer 12 of the estrus detection sheet 21, but the print density (number of prints) of the circular marks 3 is small in the central part, and the printing density increases as the distance from the central part increases. Is large (the number of prints is large). The change in the print density changes rapidly as the distance from the center portion increases. Therefore, in the estrus detection sheet 21, the number of marks 3 exposed increases rapidly as the number of mountings increases and the peeling of the release coat layer spreads left and right. For this reason, the estrus detection sheet 21 of this embodiment can detect the degree of estrus more correctly than the conventional estrus detector 10 in which the exposure area increases in proportion to the number of mountings.

  FIG. 2C shows the structure of the estrus detection sheet 22 of the second embodiment of the livestock estrus detector 20 of the present invention, in which the mark 4 printed on the display layer 12 has a triangular shape. . Thus, the estrus detector 20 of the present invention can be prepared in various types by changing the shape of the mark printed on the display layer 12. For this reason, it is possible to easily and accurately determine whether or not the cow's estrus is in the fertilization appropriate period according to the type of the mark.

  FIG. 3A shows the structure of the estrus detection sheet 23 of the third embodiment of the livestock estrus detector of the present invention. The estrus detection sheet 21 shown in FIG. 2A is a mark printed on the display layer 12. The form of 5 is different. In the first and second embodiments, the number of marks 3 and 4 is small at the center of the display layer 12 and the number of marks printed increases as the distance from the center to the left and right increases. In the third embodiment, the area of the rectangular mark 5 on the estrus detection sheet 23 is small at the center of the display layer 12, and the area rapidly increases as it moves away from the center.

  FIG. 3B shows the structure of the estrus detection sheet 24 of the fourth embodiment of the estrus detector for livestock of the present invention. The estrus detection sheet 21 shown in FIG. 2A is a mark printed on the display layer 12. Is different. In the first and second embodiments, the number of prints of the marks 3 and 4 is small in the central portion of the display layer 12 and increases from the central portion to the left and right, but in the estrus detection sheet 24, from the central portion. As the distance from the left and right increases, the shape of the mark changes to mark 4, mark 6, mark 7, and mark 3, and the area of the mark itself gradually increases. That is, the mark 4 in the center is a triangle, and changes to a star-shaped mark 6, a hexagonal mark 7, and a circular mark 3 as it moves left and right from the center so that the area of one mark increases. It has become. In this embodiment, the number of printed marks may be changed at the same time as in the previous embodiment.

  FIG. 4A shows the structure of the estrus detection sheet 25 of the fifth embodiment of the estrus detector for livestock of the present invention. In the estrus detection sheets 21 to 24 of the first to fourth embodiments described above, the marks 3 to 7 having various shapes are printed on the display layer 12. On the other hand, the estrus detection sheet 25 of the fifth embodiment is different in that the mark is a barcode 8. Since the bar code 8 can represent a number, in the fifth embodiment, the number (123 456 001) indicated by the bar code 8 at the center and the bar code 8 printed at a position left and right away from the center are displayed. The numbers shown (123 456 002, 123 456 003) are different.

  In the fifth embodiment shown in FIG. 4A, the number of the bar code 8 printed at a position that is equidistant from the center portion on the left and right may be the same or different. In the fifth embodiment, a case is shown in which the numbers of the bar codes 8 printed at the same distance from the center portion at the right and left are the same. Note that the bar code 8 and the numbers below the bar code 8 shown in FIG. 4A are examples, and the illustrated ones do not indicate actual codes and numbers. Further, as in the modified example of the fifth embodiment shown in FIG. 4C, the direction of the bar code 8 can be set to the vertical direction so that the number represented by the bar code 8 increases as the distance from the center increases. . In the modification of the fifth embodiment shown in FIG. 4C, the numbers represented by the barcodes 8 are all different.

  FIG. 4B shows the structure of the estrus detection sheet 26 of the sixth embodiment of the estrus detector for livestock of the present invention. In the fifth embodiment, the mark is the barcode 8, but in the estrus detection sheet 26 of the sixth embodiment, the mark is the two-dimensional barcode 9. Since the two-dimensional barcode 9 can also represent a number, the number indicated by the two-dimensional barcode 9 in the central portion and the two-dimensional barcode 9 printed at a position left and right away from the central portion are also included in the estrus detection sheet 26. The numbers shown are different.

  In the sixth embodiment shown in FIG. 4B, the number of the two-dimensional barcode 9 printed at a position that is equidistant from the center portion on the left and right may be the same or different. Note that the two-dimensional barcode 9 shown in FIG. 4B is an example, and the illustrated one does not indicate an actual code. Further, the shape of the two-dimensional barcode 9 can be reduced so that the number of the two-dimensional barcodes 9 gradually increases as the distance from the center increases. Conversely, as in the modification of the sixth embodiment shown in FIG. 4D, the shape of the two-dimensional barcode 9 is increased to reduce the number of two-dimensional barcodes 9 on the estrus detection sheet 26, and all The number represented by the two-dimensional barcode 9 may be changed. In the modification of the sixth embodiment shown in FIG. 4D, the numbers represented by the barcodes 9 are all different.

  Further, as another modification of the fifth and sixth embodiments, as shown in FIGS. 4E and 4F, the barcode 8 or the two-dimensional barcode 9 to be printed on the display layer 12 is greatly enlarged. Alternatively, only one may be printed on the display layer 12. In these modified examples, even if a barcode reader for reading the barcode 8 or the two-dimensional barcode 9 printed on the estrus detection sheets 25 and 26 is installed at a position away from the cow, the barcode 8 or the two-dimensional The bar code 9 can be read.

  The marks 3 to 7, the barcode 8, or the two-dimensional barcode 9 can be printed on the estrus detector by a method such as film transfer, silk screen marking, ink jet printing, embossing, laser marking, or the like. Further, as in the fifth and sixth embodiments, in the estrus detection sheets 25 and 26 in which the mark is the barcode 8 or the two-dimensional barcode 9, the number indicated by the barcode 8 or the two-dimensional barcode 9 is set. The individual registration number of the cow to which the estrus detection sheets 25 and 26 are attached, the livestock number of the farm where the cow is bred, and the like can be registered in the computer. In this manner, the number indicated by the barcode 8 or the two-dimensional barcode 9 is registered in the computer in association with the individual registration number of the cow to which the estrus detection sheets 25 and 26 are attached, the livestock number of the ranch where the cow is bred, etc. Then, the estrus time of each cow can be managed with a computer.

  For example, as a method of associating the number indicated by the barcode 8 with the individual registration number of the cow to which the estrus detection sheet 25 is attached, the livestock number of the ranch where the cow is bred, etc., for example, there is a method shown in FIG. 4G. In the method shown in FIG. 4G, in order to protect the estrus detection sheet 25 in an unused state, it was printed on the display layer 12 on the surface of the release coat layer 16 and the surface of the liner paper 15 attached to the surface of the adhesive layer 14. The same barcode 8 as the barcode 8 is printed. Further, in the method shown in FIG. 4G, a picture 19 of an ear tag attached to the cow's ear is printed on a part of the liner paper 15, and the livestock number of the cow to which the estrus detection sheet 25 is pasted on the ranch side is displayed. It is possible to write in the ear tag picture 19 by hand. By this method, the number indicated by the barcode 8 can be associated with the individual registration number of the cow to which the estrus detection sheet 25 is attached, the livestock number of the farm where the cow is bred, and the like.

  In the case of the fifth and sixth embodiments, the barcode 8 or the two-dimensional barcode 9 printed on the display layer of the estrus detection sheets 25 and 26 is covered with a release coat layer before use and viewed from the outside. I can't. For this reason, before attaching the estrus detection sheets 25 and 26 to the cow, the barcode 8 or the two-dimensional barcode 9 printed on the display layer cannot be registered in the computer. An embodiment in which this is improved is shown in FIGS. 5A to 5E.

  FIG. 5A shows an estrus detection sheet 26A of a modified example in which a window-shaped notch 17 is provided in the center of the release coat layer 16 in the estrus detection sheet 26 of the sixth embodiment shown in FIG. 4B. . The window-shaped notch 17 can be formed by omitting application of the release coat layer 16. FIG. 5B is a plan view of the estrus detection sheet 26A shown in FIG. 5A. In the estrus detection sheet 26A of the modified example of the sixth embodiment, the two-dimensional barcode 9 printed on the display layer 12 of the estrus detection sheet 26A is used before the estrus detection sheet 26A is used, and the estrus detection sheet 26A is used as a cow. Even after mounting and before mounting, it can be seen from the outside through the window-shaped notch 17. For this reason, before sticking the estrus detection sheet 26A to the cow, the two-dimensional barcode 9 printed on the display layer 12 can be registered in the computer.

  FIG. 5C shows another example of the sixth embodiment in which a rectangular cutout 18 is provided at one end of the four corners of the release coat layer 16 in the estrus detection sheet 26 of the sixth embodiment shown in FIG. 4B. The estrus detection sheet | seat 26B of a modification is shown. The rectangular notch 18 can be formed by omitting application of the release coat layer 16. FIG. 5D is a plan view of the estrus detection sheet 26B shown in FIG. 5C. Also in the estrus detection sheet 26B of another modification of the sixth embodiment, the two-dimensional barcode 9 printed on the display layer of the estrus detection sheet 26B is used as the cow before use of the estrus detection sheet 26B and the estrus detection sheet 26B as a cow. It can be seen from the outside through the rectangular notch 18 until it is mounted after being attached to. For this reason, before sticking the estrus detection sheet 26B to the cow, the two-dimensional barcode 9 printed on the display layer can be registered in the computer.

  FIG. 5E shows still another embodiment of the sixth embodiment in which only one two-dimensional barcode 9 is printed at the center of the release coat layer 16 in the estrus detection sheet 26 of the sixth embodiment shown in FIG. 4B. It is a top view which shows the estrus detection sheet | seat 26C of the modified example. The two-dimensional barcode 9 printed on the central portion of the release coat layer 16 may be the same two-dimensional barcode 9 as the two-dimensional barcode 9 in the central portion of the display layer or a different two-dimensional barcode 9. Further, in another estrus detection sheet 26C, the two-dimensional barcode 9 printed on the surface of the release coat layer 16 is mounted before the estrus detection sheet 26C is used and after the estrus detection sheet 26C is attached to the cow. It can be seen from the outside even before is done. If the two-dimensional barcode 9 is printed on the surface of the release coat layer 16, the two-dimensional barcode 9 printed on the display layer can be registered in the computer before the estrus detection sheet 26C is attached to the cow. The modification of the sixth embodiment described above can also be applied to the estrus detector 20 on which the marks 3 to 7 are printed.

  Further, if a barcode or a two-dimensional barcode is printed on a liner paper attached to the adhesive layer 14 and the release coat layer 16 in order to protect the adhesive layer 14 and the release coat layer 16, the liner paper can be used to Codes and 2D barcodes can be registered in the computer.

  FIG. 6A shows the structure of the livestock estrus detection sheet 27 of the seventh embodiment of the livestock estrus detector of the present invention, and FIG. 6B shows the state after the manufacture of the estrus detection sheet 27 shown in FIG. 6A. FIG. The estrus detection sheet 27 of the seventh embodiment has a display layer 12 with a color that can be seen well from a distance on the upper surface side, an adhesive layer 14 provided on the lower surface of the display layer 12, and an upper surface of the display layer 12. It is formed from the release coat layer 16 to be applied. In the estrus detection sheet 27 of the seventh embodiment, a number of two-dimensional barcodes 9 are printed as marks on the upper surface side of the release coat layer 16.

  Accordingly, the estrus detection sheet 27 of the seventh embodiment can read the two-dimensional barcode 9 printed on the release coat layer 16 in an unused state or a state before being mounted after being attached to a cow. When the peeling coat layer 16 is peeled from the display layer 12 by mounting, the two-dimensional barcode 9 cannot be read and the color of the display layer 12 can be visually observed. The mark may be another mark 3 to 7 or a barcode 8.

  FIGS. 6C to 6E show the peeled state of the peel coat layer 16 from the display layer 12 and the change in the degree of color exposure of the display layer 12 by mounting after the estrus detection sheet 27 shown in FIG. 6B is attached to the cow. It is. FIG. 6C shows a state in which the number of mountings is one, and it can be seen that it is difficult to read the two-dimensional barcode 9 at the center. FIG. 6D shows a state in which the number of mountings is 3 to 5, and it can be seen that it is difficult to read the two-dimensional barcode 9 at the center and both sides thereof. FIG. 6E shows a state when the number of mountings is 5 or more, and it is difficult to read all the two-dimensional barcodes 9, and it can be seen that most of the display layer 12 is exposed. Thus, the estrus detection sheet 27 of the seventh embodiment can detect the degree of estrus when the two-dimensional barcode 9 becomes difficult to read.

  In the case of the seventh embodiment, the two-dimensional barcode 9 printed on the release coating layer 16 of the estrus detection sheet 27 peels off from the display layer and cannot be seen from the outside when the number of mountings increases. Therefore, as shown in FIG. 7A, the same two-dimensional barcode is printed at the center of the display layer 12 of the estrus detection sheet 27 of the seventh embodiment shown in FIG. 6A, or as shown in FIG. 7B. The same two-dimensional barcode may be printed on one end of the display layer 12 of the estrus detection sheet 27 of the seventh embodiment shown in FIG. 6A. In these structures, even if the two-dimensional barcode 9 printed on the release coat layer 16 is completely peeled off by mounting, the original two-dimensional barcode 9 is confirmed by the two-dimensional barcode 9 printed on the display layer 12. can do.

Read. When the barn is dark, the video camera 32 is preferably an infrared camera. Further, the recent barcode reader 31 can read a two-dimensional barcode in addition to reading a barcode, and further can read an IC tag. Therefore, when using a barcode reader 31 that can read even an IC tag, it is possible to embed an IC tag 34 or an antenna circuit in the display layer 12 of the estrus detector 20 as shown in FIG. 9B. is there.

  The reading information of the barcode 8 read by the barcode reader 31, the reading information of the two-dimensional barcode 9, or the reading information of the IC tag 34, and the image data read by the video camera 32 are input to the computer 30. Analysis of mark exposure, mark exposure area, mark type, barcode information, two-dimensional barcode information, IC tag data, or image information is stored in advance in the database 33. Based on the comparison.

  The database 33 stores the exposure amount of the mark indicating the degree of estrus of the cow, the exposed area of the mark, the type of the mark, the barcode information, and the two-dimensional barcode information. It is possible to store an individual registration number, data of a farm number of a cow in a farm where a cow is bred, and the like. Therefore, when attaching the estrus detector 20 to the cow, if the information of the estrus detector 20 is associated with the information of the cow to which the estrus detector 20 is attached, the record of the breeding of each cow is managed by the computer 30. It is possible.

  Further, when the barcode reader 31 reads the two-dimensional barcode 9 printed on the estrus detector 20, even if the numbers represented by the two-dimensional barcode 9 are the same, that is, the same two-dimensional barcode 9 is displayed. Even if several display layers 12 are printed, it is possible to distinguish a plurality of two-dimensional barcodes 9 on the reading software side. The case of the estrus detection sheet 26 having the two-dimensional barcode 9 shown in FIG. 4D will be described with reference to FIG.
