Description

Heat detection device of cattle

The present invention relates to an apparatus for detecting a cow's estrus, and in particular, by configuring means for monitoring a vocal sound or behavior of a cow's estrus, to accurately detect a cow's estrus, estrus initiation time, and estrus progress, thereby precisely determining a cow's estrus timing. The present invention relates to a cow estrus detecting device capable of detecting and conceived in time and thereby increasing income of livestock farmers.

In general, the estrous cycle of cattle is known to be about 21 days, and the estrus of the estrus is characterized by a pronounced voice, the number of steps, and the increase in the number of stool and urine shows a big difference from normal.

In addition, the biggest characteristic of the horned cow's behavior is the multiplication act, which means tolerating the bull's act of another cow next to it or to get on the back of another cow. The appraisal activity lasts only about 4 to 6 seconds each time, and appears for a short period of time, around 5 minutes during the whole estrous period.

Conventionally, a worker of a livestock farm is observing cows to determine whether they are estroused by the naked eye, and according to the naked eye, the edema and the change of pink color, the occurrence of exudate and the number of urine and feces are increased. It was very difficult to observe the estrus timing of the cow precisely due to the change in the number of steps and the vocalization, and the best behavior for the observing the estrus timing with the naked eye, which occurs temporarily in a very short time, usually occurs at night. Since there are many cases, it is difficult for workers to accurately capture this problem. As a result, the cow's publicity increases and the income of livestock farmers decreases, because the cow's approval behavior is not accurately captured.

Accordingly, the present invention for solving the above problems constitutes a means for monitoring the vocal sound or behavior of the horn of the estrus, using the various information detected from the estrus whether or not the estrus and estrus start time, estrus progress state By accurately detecting the estrus, it is an object of the present invention to precisely detect the estrus timing of the cow to conceive in time, thereby providing a cow estrus detection device to increase the income of livestock farmers.
