Definitions

  • the present invention is related to an estrus notifying method, an estrus notifying apparatus, and an estrus notifying program.
  • a technique of attaching a pedometer to livestock such as grazing cattle and measuring the number of steps walked to detect changes in the state of the animal, such as the onset of estrus or illness is known. Based on the detection of a change in the state of the animal via the pedometer, a worker makes a determination such as whether to mate the animal, administer medical treatment, etc.
  • one object of the present invention is to provide an estrus notifying method, an estrus notifying apparatus, and an estrus notifying program that can effectively identify livestock animals indicating estrus.
  • an estrus notifying method, an estrus notifying apparatus, and an estrus notifying program that give notification of estrus based on step count measurement results from a step counting device attached to livestock animals are proposed.
  • the estrus notifying method, the estrus notifying apparatus, and the estrus notifying program collect step a count measurement result for each livestock animal and position information of each livestock animal, and based on the step count measurement results and a first condition, determine whether each of the livestock animals is in estrus.
  • the estrus notifying method, the estrus notifying apparatus, and the estrus notifying program refer to a memory unit that retains the working hours of a worker, and determine whether the current time is included in the working hours. If the current time is included in the working hours, the estrus notifying method, the estrus notifying apparatus, and the estrus notifying program determine whether livestock animals near the given livestock animal indicate estrus, based on the step count measurement results and a second condition that is more lax than the first condition; and output the identification information of the given livestock animal determined to be in estrus and the identification information of the livestock animals determined to indicate estrus.
  • livestock animals indicating estrus can be effectively identified.
  • FIG. 1 is a diagram depicting an example of the estrus notifying method according to the present embodiment.

  • a communications device 101 is attached to each livestock animal A.
  • the communications device 101 is a portable computer that measures a step count of the livestock animal A. For example, when the livestock animal A walks, the livestock animal A steps with the right-front leg, sending the leg out toward the ground in the direction of travel. Upon planting the right-front leg on the ground, next, the livestock animal A steps with the left-front leg, sending the leg out toward the ground in the direction of travel. Upon planting the left-front leg on the ground, again, the livestock animal A steps with the right-front leg, and repeats this series of actions.
  • the step count of the livestock animal A can be the number of times that the livestock animal A steps with the right-front leg or the left-front leg, sending the leg out toward the ground in the direction of travel.
  • the state of the livestock animal becomes an abnormal state, which differs from a normal state, consequent to a state change of the livestock animal A, such as the onset of estrus or illness, giving birth, the appearance of a natural predator, etc.
  • the step count per unit time of the livestock animal A increases or decreases compared to that for the normal state.
  • estrus is an excited state accompanying reproductive activity of the livestock animal A.
  • Illness is a state in which the physical or emotional state of the livestock animal A is poor or unfavorable.
  • the change in the step count of the livestock animal A is used to measure the step count of the livestock animal A, whereby the worker W can know that a change has occurred with the livestock animal A from the step count measurement result.
  • the communications device 101 is capable of communicating with multiple relay devices 102 installed within the premises of the farm F.
  • a relay device 102 is a computer that is capable of communicating with the communications device 101 and an estrus notifying apparatus 104 described hereinafter.
  • Each of the relay devices 102 is installed at a different position in the farm F.
  • the communications device 101 via a communicable relay device 102, transmits measurement result information that indicates measurement results to the estrus notifying apparatus 104.

Further, if the communications device 101 is located in a communications area 103b of a relay device 102b indicated as an example in FIG. 1 by reference numeral 102b, the communications device 101 can communicate with the relay device 102b. If the communications device 101 is located in a communications area 103c of a relay device 102c indicated as an example in FIG. 1 by reference numeral 102c, the communications device 101 can communicate with the relay device 102c.
  • a communications area for example, is a 150-meter radius around the relay device 102.

  • an example will be given describing a technique of finding an estrus state of a female cow.
  • the worker W periodically goes out to the pasture area, and actually visually confirms whether a female cow in estrus is present. Since the worker W has to make search rounds in the farm F, which is extremely large covering several 100 meters to several kilometers on a side, this technique, for example, not only takes time, but also is a burden to the worker W and ultimately, has a high personnel cost. Therefore, although mating implemented by the worker W during pasturing may be foregone, no mating of a female cow in estrus, i.e., not implementing mating when the potential of fertilization is high is a financial loss.
  • the worker W may also pasture stud bulls for natural mating to occur.
  • natural mating by a stud bull is not desirable from the viewpoint of current livestock management ideals of producing better offspring.
  • bulls are aggressive, only an experienced worker W can handle the bulls and thus, is not an effective technique.
  • a system uses the property that the step count increases for a female cow in estrus, and attaches to a female cow, a pedometer that measures step count.
  • the pedometer attached to the female cow transmits measurement results to a server, at given transmission intervals, via a relay device installed in the pasture area.
  • the worker W can surmise the position of the female cow in estrus.
  • the object of the system itself is to detect female cow estrus. Therefore, the pedometer, for example, is set to transmit measurement results at one-hour intervals.
  • the worker W may be involved with other work such as cleaning the cattle shed and thus, cannot immediately go to the vicinity of the relay device (i.e., cow in estrus). In such a case, when the worker W goes to the vicinity of the relay device, the cow in estrus, which moves moment to moment, may have moved from the vicinity of the relay device and in the end, the worker W has to search the pasture area, which a burden on the worker W.
  • the estrus notifying method of the present embodiment even if a livestock animal is in estrus, in cases where the worker cannot go to the livestock animal immediately such as during hours outside of working hours, the minimally required information is notified to prevent, as much as possible, adverse effects consequent to misjudgment, to suppress the burden placed on the worker W, and to prevent the worker W from becoming exhausted. Further, in the estrus notifying method of the present embodiment, in cases when during the working hours of the worker, the worker can go to a female cow in estrus, the worker is prompted to check the livestock animal in estrus as well as other livestock animals that can be checked on.
  • estrus will be taken as one example of an abnormal state of the livestock animal A.
  • livestock animal A will be described as a female cow.

  • the estrus notifying apparatus 104 notifies the worker W of the livestock animal A1 satisfying the first determination condition and the livestock animal A2 satisfying the second determination condition and located near the livestock animal A1 ( FIG. 1 (3)). On the other hand, if the estrus notifying apparatus 104 determines that the current time is not within the working hours, the estrus notifying apparatus 104 notifies the worker W of only the livestock animal A1 satisfying the first determination condition. Furthermore, configuration may be such that if the estrus notifying apparatus 104 determines that the current time is not within the working hours, the estrus notifying apparatus 104 gives no notification concerning the livestock animal A1 satisfying the first determination condition to the worker W.
