It is intended to improve the pig weight measurement unit provided in the weight measurement stage of FIG. 4 .

Existing pig weight measurement apparatus uses one or two load cells to separate the passage through which pigs pass from the floor, and to measure the weight by hanging the passage separated from the floor on a load cell provided on the upper part. This allowed the pigs to be weighed using a small number of load cells.

However, with this method, the aisle may shake while the pig passes through it, which often makes the pig uneasy.

In order to improve this point and accurately measure the weight of a pig, the present invention installs four or more load cells, more preferably, six load cells at the corner of the passage and at the center of the left and right long sides so that the weight of the pig can be measured. .

In this way, it was possible to measure the pig's weight and gait, which were changed according to the passage movement of the pig. With this configuration, it was possible to determine whether the gait was unstable by analyzing the left-right symmetry of the pig's gait, gait and speed, etc.

That is, the time interval between steps, step length, and the change in the center of gravity during walking can be analyzed using the measured values of the six load cells.

In addition, it can be used as a sensor that can close the entrance of the breeding device to block the entry of other pigs by recognizing that the pig has completely entered the passage when a large amount of weight is put on the load cell installed in the innermost part of the passage among the six load cells. Do.

In particular, in the process of the pig entering the passage, the weight of the left and right load cells measured on the six load cells is measured and the weight of the stagnant pig is measured and compared to determine whether the same weight is loaded on the left and right while the pig is standing or walking This can be used to determine whether the pig's gait is abnormal.

In addition, it is possible to recognize a pig by using a pig stamp composed of RFID installed at the entrance of the breeding device, and determine whether the pig's gait is stable or unstable by comparing it with previously stored gait data of the same pig. It was made to compare whether the gait was the same as the gait judged by estrus in the past.

In particular, it can be known whether the gait of the pig is unstable by performing frequency analysis along with size analysis of the measured data of six load cells.

That is, if there is low-frequency vibration from the data of the load cell that measures the weight of the pig, it can be determined that the pig shows anxiety symptoms. As for the low frequency, data in the vicinity of 5 to 20 Hz can be checked. If such an unstable gait is confirmed, it is judged as estrus of a pig.

In addition, a pheromone generator is provided in the lower portion where the head of the pig in the front part of the weighing unit is located. When a frequency of 10 Hz or higher is measured by frequency analysis of the load cell measurement data, it is determined as estrus, and the pheromone generator supplies a pheromone fragrance to the pig to determine whether the pig determined to be in estrus is in estrus to determine the weight change of the load cell. It provides a breeding apparatus, characterized in that for measuring the reaction of the pig. In the case of pigs that are not in estrus, there is no change in the movement of the pig measured in the load cell before and after supplying the pheromone scent because the pheromone scent is not affected.

Pigs in estrus find a sense of stability by the scent of the pheromone and the measured value changes.

A common method of observing estrus in sows is to know whether the vulva is swollen and congested, whether mucus is leaking from the vulva, and whether the sow is allowed to succumb.

However, it is not easy to make such observations when breeding sows and sows separately. Therefore, by measuring the gait of pigs entering the automatic breeding device and a test using a pheromone generator to confirm the pig's estrus, and then notify the farm manager of this, it is possible to actively check the estrus of the pig and take appropriate follow-up grass accordingly. Of course.
