Sow estrus checking method, device and system

Abstract

The invention provides a sow estrus checking method, device and system. The sow estrus checking method comprises the following steps: collecting continuous multi-frame face images of a to-be-tested sow; under the condition that it is determined that the posture of the mouth and nose of the to-be-detected sow is stable according to the continuous multiple frames of face images, estrus inducing pheromone is sprayed to the mouth and nose of the to-be-detected sow; and displaying the holographic image of the boar, and continuously pressing the back of the to-be-tested sow by using a back pressing plate to obtain a feedback pressure curve for determining the estrus state of the to-be-tested sow. According to the method, the holographic image of the boar is fused with the estrus inducing pheromone, the back pressure feedback pressure of the to-be-detected sow is collected, the feedback pressure curve is constructed, the estrus state of the sow is judged, the sow is stimulated to be in estrus from multiple aspects such as vision, smell and touch, the real boar is not used, the number of estrus checking personnel for controlling the boar is reduced to a great extent, and the working efficiency is improved. In addition, direct contact between boars and sows and indirect contact between the sows in all the fences are avoided, the virus spreading possibility is reduced, and the detection precision and the detection efficiency are effectively improved.

Description

technical field [0001] The invention relates to the technical field of animal husbandry intelligent equipment, in particular to a sow estrus checking method, device and system. Background technique [0002] In the production and breeding process of large-scale pig farms, it is necessary to regularly obtain the estrus status of empty pregnant sows, and mark and record the estrus status of each sow in time to facilitate subsequent related work. [0003] The traditional way to determine the estrus status of sows is to use the method of combining manual estrus detection and boar estrus testing. At least two estrus checkers are required to perform it. One of the estrus checkers will lead the boar to the estrus check area of ​​​​the empty sows, and control the estrus check of the male pigs. The pig is in direct contact with the mouth and nose of the sow in the pen; another estrus inspector stimulates it by looking at the vulva, scratching the pig's back, riding on the pig's body, ...

AI Technical Summary

Problems solved by technology

[0005] There are mainly two types of traction by the situation-checking vehicle. One is to drive the boar to the situation-checking vehicle. The situation-checking vehicle is controlled by the remote control of the personnel. The side gate of the boar’s head to be checked is opened so that the boar and the sow to be checked can have mouth-nose contact. There are also defects such as the risk of transmission of common diseases between humans and pigs, and the efficiency of checking the heat is low, and the limited mechanism and the capacity of the car body and so on, it will increase the stress of boars; the other is that boars are free or forced to follow the estrus inspection vehicle. This method can reduce the size of the estrus inspection vehicle and improve the stress response of boars, but it also has Defects such as difficulty in boar walking, slipping of pig's feet, cleaning of feces in boar's walking area, and boar's lack of cooperation caused by wet ground
