Identification of the best insemination time of sows by hand pressure method
The inseminator stands on one side of the oestrus sow, facing the sow's back, extends his hands horizontally, gently places them on the sow's back, and then gradually presses down hard. At this time, if the sow's back suddenly bows up and has a sense of upward rebound, press down for 1-2 minutes, the sow stands still and does not cry constantly, which is the best time for inseminating; if the sow moves back and forth with cries when pressing down, it is not the best time for inseminating.
