Description

The present invention relates to an estrus reporting system for detecting and reporting the estrus of cattle, and in particular, to accurately detect estrus by clearly distinguishing between illness and estrus represented by mastitis, and communicating with a cow manager or the like It relates to the estrus reporting system that reports at

  The conventional estrus reporting system started to increase the body temperature by inserting a temperature sensor that measures the body temperature of the cow into the body of the cow based on the fact that the body temperature of the cow rises above the normal temperature during the estrus period of the cow. Therefore, it is determined that an estrus tendency has appeared, and a report is made (see, for example, Patent Document 1).

JP 2002-159233 A Japanese Patent No. 3938786

However, the rise in body temperature of cattle is not limited to estrus, and body temperature rises even when suffering from diseases represented by mastitis, so detect estrus by raising body temperature and ask an artificial inseminator, At the time of seeding, there was a case where an oscillating swing occurred, which was actually not in an estrus state, but was found to be due to an increase in body temperature caused by a disease.
Needless to say, this was a waste of time and money for dairymen.

In view of the above problems, an object of the present invention is to provide an estrus reporting system capable of detecting and reporting cow estrus separately from disease based on cow vagina temperature.

The estrus reporting system according to claim 1 of the present invention is inserted into the vagina of a cow, measures the intravaginal temperature every predetermined time, and transmits the measured intravaginal temperature together with its own ID wirelessly. A receiving module that receives the intravaginal temperature and ID from the transmitting module, and a normal temperature that confirms that the intravaginal temperature A received by the receiving module is an ordinary temperature of 37.0 ° C. <A <39.5 ° C. Confirmation means, moving average means for calculating the moving average for 4 hours of the intravaginal temperature confirmed as normal heat by the normal heat confirmation means for each cow based on the ID, and the moving average B calculated by the moving average means Memory, read out after 24 hours (C), read out after 48 hours (D) memory means and when B ≧ C + 0.4 ° C. and B ≧ D + 0.4 ° C. that the cow is in estrus Estrus detection means for detecting, and estrus detection means There a transmission module for transmitting that it has ID and estrus cow detected to be in estrous state, the estrus detection means, after detecting the estrus status, check the vaginal temperature the normal temperature check means is not a normal temperature If you cancel that the estrus state, the transmission module is characterized that you send the information of the cancellation.

  According to the present invention, a disease represented by mastitis and estrus can be clearly distinguished to accurately detect estrus, and a cattle administrator or the like can be notified via a communication line.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram showing an overall configuration including an estrus notification system according to an embodiment of the present invention. The estrus reporting system 10 of this embodiment includes a receiving module 11, a CPU (Central Processing Unit) 12, a memory 13, and a transmitting module 14. The temperature measurement / transmission module 20 is inserted into the cow's vagina, measures the temperature in the vagina with a thermometer, and transmits the measured temperature and its own ID (identification number) every 5 minutes. The mobile phone 30 is a generally known mobile phone, which receives the estrus information transmitted by the estrus reporting system 10 and the cow is in an estrus state for a dairy farmer who is an owner of the cow who owns the estrus information. Or in an estrus state. The mobile phone 30 may be a personal computer having a communication function.

  The reception module 11 receives the cow vagina temperature and ID from the temperature measurement / transmission module 20 and sends them to the CPU 12. The CPU 12 and the memory 13 receive the vaginal temperature and ID, detect the estrus state of the cow according to the program of this embodiment, and send it to the transmission module 14. The transmission module 14 transmits information related to the fact that the cow corresponding to the ID is in the estrus state or in the estrus state to the mobile phone 30.

FIG. 2 is a flowchart showing the operation of the program in the estrus notification system according to one embodiment of the present invention. First, the vagina temperature (this is assumed to be A) every 5 minutes is received and stored (step S1). here,
37.0 ° C. <A <39.5 ° C. (1)
(NO in step S2), and if the temperature in the vagina is not within this range, it is determined that the cow is not normal, and the estrus is not determined and no notification is made. If the estrus report has already been reported (described later), the estrus report is canceled because the estrus report is erroneous (step S3). By this determination, it is possible to prevent the cattle from reporting estrus when the cow is a disease represented by mastitis and the vagina temperature has risen and is not estrus. In step S2, if it is YES and the intravaginal temperature is within this range, it is determined that the cow is normal and the estrus is determined. First, the moving average of the vagina temperature A over 4 hours is taken and stored (step S4, this moving average is B). All the vaginal temperatures A for which the moving average is taken satisfy the formula (1), and if none is satisfied, the moving average is not calculated. Then, the stored moving average of 4 hours before 24 hours is read (step S5, the read moving average is C), and further, the moving average of 4 hours before 48 hours is read (step S6, This read moving average is defined as D). here,
B ≧ C + 0.4 ° C. and B ≧ D + 0.4 ° C. (2)
(NO in step S7), and if the moving average B has not increased, it is determined that no estrus has occurred and no estrus notification is made (step S8). If YES in step S7 and the moving average B increases, it is determined that the cow of that ID has estrus and reports that it has been estrus (step S9). Thus, by detecting that the moving average of the vagina temperature has risen, it is possible to determine estrus in consideration of individual differences in normal heat of cows.

  In addition, when the vagina temperature rises slowly due to disease (specifically, when it takes more than 4 hours to take a moving average), it may be temporarily determined as estrus in the process. However, as described in the present embodiment, since the estrus notification is canceled immediately after that, there is substantially no trouble.

FIG. 3 is a graph showing a specific example of vaginal temperature data of an example in which estrus is determined for 11 cows. FIG. 4 is a graph showing a specific example of the average vaginal temperature data of the 11 animals. In FIG. 4, the temperature suddenly drops last because the temperature measurement / transmission module 20 is pulled out from the vagina. FIG. 5 is an enlarged graph of FIG. 3 for three of the 11 cows in FIG. 6-8 is a figure which shows the specific example of the vagina temperature data of the example which carried out the estrus determination. FIG. 9 is a diagram showing a specific example of vaginal temperature data at the time of illness. FIG. 6 shows the body temperature every 5 minutes of body temperature every 5 minutes of February 4-7, 2012, the moving average of body temperature every 5 minutes over 4 hours, and 48 hours before that. The difference between the moving average of 4 hours and the moving average of 4 hours before 24 hours is shown. Assuming that the original data satisfies the formula (1), when both moving average differences are 0.4 ° C. or more, it is determined that it is estrus and is reported.
FIG. 7 is a similar example of the test cow 2.
FIG. 8 is a similar example of the test cow 3 from January 26 to 29, 2012.

FIG. 9 is an example in which the test cow 12 suffered from mastitis on August 9-13, 2008. In this case, the body temperature reached 39.5 ° C. or higher, and no estrus report was made. .
In addition, this invention is not limited to the said Example.
By adding software (program) to the present invention, it is also possible to detect a decrease in vaginal temperature and to predict and report cow calving (see Patent Document 2).

Moreover, as shown also in FIGS. 5-8, in addition to the report of estrus, it is also possible to report an insemination appropriate period which is the optimal time for artificial insemination. Specifically, after estrus, the vagina temperature fell,
B ≦ C + 0.4 ° C. or B ≦ D + 0.4 ° C. (3)
When it becomes, it is judged that the insemination is appropriate, and insemination is reported. The period is about 12 hours after the start of estrus, but there are actually differences among cows. In the case of the test cow 1 shown in FIG. 6, it was 11 hours later, in the case of the test cow 2 shown in FIG. 7, after 16 hours, and in the case of the test cow 3 shown in FIG.

  As described above, since the start of estrus can be known by notification according to the present invention, it is possible to prepare for artificial insemination with a margin, and since it is possible to know the optimal period of subsequent insemination by notification, the optimal time is reached. Since artificial insemination can be performed, the accuracy of insemination can be increased.
