Definitions

  • the present invention relates to a device for detecting estrus in livestock, especially cows.
  • estrus In cows, and particularly, to find out when cows come into estrus.
  • Some devices for detecting estrus include a pedometer (see Patent Literature 1).
  • Such a pedometer is attached to a target cow.
  • the detection device divides each day into a plurality of time periods, and extracts the number of her steps counted by the pedometer for each time period.
  • the detection device then compares the counted steps with the number of her steps corresponding to the same time period in the past "n" days, thereby determining whether the cow is in estrus or not from the comparison result.
  • the device includes counting device 101 and a least one pedometer 102.
  • Counting device 101 includes computer 103 and communication device 104.
  • Pedometer 102 is secured to a cow's body, for example, around a cow's neck or leg with a belt or something.
  • Pedometer 102 includes a step counting unit, a communication unit, and a control unit.
  • the step counting unit counts the number of her steps, and transmits it to the control unit.
  • the control unit accumulates the number of her steps up to a predetermined time, and transmits the accumulated value to the communication unit together with a signal for identifying individual cows.
  • the communication unit receives the accumulated value and the signal, and transmits them to communication device 104. After the communication unit transmits the value and the signal to communication device 104, the control unit resets the accumulated value.
  • Computer 103 stores the data of the number of her past steps in the form of, for example, D 1 , D 2 , D 3 , D 4 (2003).
  • Computer 103 compares the number of her most recent steps received from communication device 104 with the data of the number of her past steps. When the comparison indicates that the number of her most recent steps is larger than the data of her past steps, computer 103 determines that the cow is in estrus.

  • Inner rib 26 is taller than outer rib 25.
  • packing 27 which is used to seal case 2.
  • the packing is made of foam mainly composed of ethylene-propylene-diene rubber (EPDM), which is excellent in weather resistance and heat resistance.
  • EPDM ethylene-propylene-diene rubber
  • Cover 21 has projection 28, which is formed around window 23 in such a manner as to project in the direction opposite to display part 30.
  • Projection 28 is formed on the entire surface of cover 21 in Fig. 3 , but may alternatively be formed at only a part of the periphery of window 23.
  • estrus detection device 1 having the above-described configuration will now be described with reference to Fig. 6 .
  • the motion of a cow equipped with estrus detection device 1 is detected by triaxial acceleration sensor 40, which outputs an electrical signal indicating the magnitude and direction of the motion.
  • the electrical signal detected by triaxial acceleration sensor 40 is converted to the amount of activity by signal processing unit 41.
  • the amount of activity is transmitted from signal processing unit 41 to temporary storage unit 42.
  • the amount of activity is stored for a fixed period of time as the present amount of activity in temporary storage unit 42.
  • a new electrical signal detected by triaxial acceleration sensor 40 is transmitted as a new amount of activity to temporary storage unit 42 via signal processing unit 41.
  • the amount of activity stored so far in temporary storage unit 42 is transmitted to storage unit 43, and is stored in storage unit 43 for the predetermined time period as the past amount of activity.
  • the present amount of activity is transmitted from temporary storage unit 42 to estrus determination unit 44, whereas the past amount of activity stored for the predetermined time period is transmitted from storage unit 43 to estrus determination unit 44.
  • Estrus determination unit 44 compares the present amount of activity with the past amount of activity, and determines whether the livestock animal is in estrus or not based on the comparison result. More specifically, upon receiving a new amount of activity from signal processing unit 41, temporary storage unit 42 transmits the present amount of activity stored so far therein to storage unit 43. Storage unit 43 stores the received present amount of activity as a past amount of activity. Estrus determination unit 44 calculates the average value of the past amount of activity, and compares it with the present amount of activity. Estrus determination unit 44 has a predetermined threshold to determine the comparison result. When the present amount of activity exceeds the threshold of the average value of the past amount of activity, estrus determination unit 44 determines that the cow is in estrus.
  • estrus determination unit 44 transmits the result to display part 30.
  • Display part 30 shows that the cow is in estrus.
  • the display is, for example, a liquid crystal display (LCD in Fig. 6 ) or a light-emitting diode (LED). With this display, estrus detection device 1 in the present exemplary embodiment informs the manager of the livestock animal that she is in estrus.
  • Estrus determination unit 44 measures the time elapsed since the cow was determined to be in estrus, and transmits the measured time to display part 30.
  • Display part 30 displays the present amount of activity in the form of numerical values.
  • estrus determination unit 44 determines that the cow went out of estrus. In the present exemplary embodiment, estrus determination unit 44 determines that estrus is over when 24 hours have passed since a cow was determined to be estrus.
  • Estrus determination unit 44 transmits the determination result to display part 30.
  • Display part 30 ends to show that the cow is in estrus.
  • estrus detection device 1 In general cows have an estrous cycle of about 21 days. Hence, when used for cows, estrus detection device 1 has only to store data for 30 days for the past amount of activity.
  • the cow After being detected to be estrus by estrus detection device 1 of the present exemplary embodiment, the cow is made pregnant by natural mating or artificial insemination.
  • estrus detection device 1 After the cow is pregnant, there is no need to detect her estrus, so that estrus detection device 1 is initialized and is attached to a different cow.
  • Estrus detection device 1 which includes triaxial acceleration sensor 40, is initialized using the characteristics of triaxial acceleration sensor 40. More specifically, if a rotation is applied to estrus detection device 1 for a specified time period, triaxial acceleration sensor 40 transmits to signal processing unit 41 an electrical signal indicating that the rotation is applied in a specific direction. Upon receiving this electrical signal, signal processing unit 41 transmits a signal for erasing the past amount of activity. Upon receiving this signal via temporary storage unit 42, storage unit 43 erases the past amount of activity. This process is referred to as a reset.
  • Triaxial acceleration sensor 40 detects the motion of a cow (S1).
  • Signal processing unit 41 converts the magnitude and direction of the detected motion of the cow to the amount of activity, and then determines whether a rotation is applied or not (S2).
  • estrus detection device 1 is initialized by a reset (S3).
  • temporary storage unit 42 stores the detected amount of activity as the present amount of activity (S4, S5).
  • the present amount of activity is updated, for example, every hour, which is the fixed period of time above-mentioned. Every time a new amount of activity is updated, the present amount of activity stored so far is transmitted to storage unit 43.
  • Storage unit 43 stores this present amount of activity as a past amount of activity.
  • the predetermined time period is 72 hours. This means that the past amount of activity is stored for 72 hours after the initialization of estrus detection device 1.
  • Estrus determination unit 44 determines whether 72 hours have passed after the initialization (S6). If the elapsed time is less than 72 hours, the processes of S4 and S5 are performed again. When the elapsed time exceeds 72 hours, estrus determination unit 44 determines whether the cow is in estrus or not based on the present amount of activity and the past amount of activity (S7). When estrus determination unit 44 determines that the cow is in estrus, estrus determination unit 44 starts to measure the elapsed time (S8). Upon being informed from estrus determination unit 44 that the cow is in estrus, display part 30 shows this information.
  • display part 30 also shows the elapsed time after the determination of estrus (S9).
  • Estrus determination unit 44 determines whether 24 hours, which is the predetermined duration above-mentioned, have passed since the cow was determined to be estrus (S10). If the elapsed time is less than 24 hours, display part 30 continues to show that the cow in in estrus. When the elapsed time exceeds 24 hours, estrus determination unit 44 transmits a signal requesting display part 30 to end to show that the cow in in estrus.
  • estrus detection device 1 can be attached only to cows that are close to estrus. This allows the detection of estrus in livestock without using a large-scale system.
  • estrus detection device 1 is initialized to be used for detecting whether another cow is in estrus. This eliminates the need to prepare estrus detection device 1 for every cow, thereby reducing the initial cost.
  • Triaxial acceleration sensor 40 as the activity sensor is located at the center of gravity of case 2.
  • Estrus detection device 1 with belt 20 is attached around the neck of a cow.
  • Conventional pedometer 102 which is attached to a cow' leg, can be accidentally stepped on by her another leg or another cow's leg.
  • estrus detection device 1 which is attached to the neck of a cow, is less susceptible to external disturbances, thereby being prevented from breakdown.
  • estrus detection device 1 is located on the center line of the body of a cow, thereby making the detection more accurate.
  • Case 2 includes cover 21 and base 22.
  • Base 22 includes outer rib 25 formed on the outer periphery of one side of board 24, and inner rib 26 formed along the inside of outer rib 25 on the same side of board 24.
  • Inner rib 26 is taller than outer rib 25. This configuration can protect case 2 from penetration of water. Providing packing 27 between inner rib 26 and outer rib 25 can further improve waterproofness of estrus detection device 1.
  • Cover 21 has projection 28 formed around window 23 in such a manner as to project in the direction opposite to display part 30. Projection 28 which encloses cover 21 is spaced apart from window 23 by a predetermined distance, thereby preventing window 23 from coming into contact with external elements.
  • Estrus detection device 1 can be initialized by applying a rotation, without opening case 2 or providing a switch for initialization. This configuration ensures the waterproofness of estrus detection device 1, allowing it to be washed while it is on a cow.
  • Fig. 8 is a block diagram of an estrus detection system.
  • the same components as in the first exemplary embodiment are denoted by the same reference numerals and the description thereof is omitted.
  • the estrus detection system includes estrus detection device 81, communication device 82, and notification device 83.
  • Estrus detection device 81 according to the present exemplary embodiment differs from estrus detection device 1 of the first exemplary embodiment in including first transmission unit 60.
  • Estrus determination unit 44 transmits the information that the cow is in estrus to first transmission unit 60.
  • First transmission unit 60 transmits a first estrus signal indicating that the cow is in estrus to first reception unit 61 of communication device 82.
  • First reception unit 61 receives the first estrus signal and transmits it to second transmission unit 62 via calculation unit 65.
  • Second transmission unit 62 transmits a second estrus signal to second reception unit 63 of notification device 83, thereby informing that the first estrus signal has been transmitted.
  • Second reception unit 63 transmits the received second estrus signal to notification unit 64 via calculation unit 66.
  • Notification unit 64 notifies that the cow equipped with estrus detection device 81 according to the present exemplary embodiment is in estrus.
  • Communication device 82 and notification device 83 may be formed as an integral component. Alternatively, it is possible to provide two or more communication devices 82.
  • Notification unit 64 may be composed of a warning light or a display.
  • Communication device 82 and notification device 83 may be wired or wireless.
  • This configuration eliminates the need to check all of estrus detection devices 81 attached to the cows. Instead, it is possible to identify cows that are in estrus according to the notification of notification device 83. This simplifies the procedure for determining estrus in cows.
  • estrus detection device is applicable not only to cows but also to other livestock such as pigs and horses which can be determined whether they are in estrus or not by their amount of activity.
