The best method for estrus identification is to perform when the sow is calm for half an hour after feeding (due to the conflict with the feeding time, it is mainly used to identify the difficult sows), estrus identification is performed twice a day, and once every morning and afternoon. Use a combination of artificial intelligence and boar trials. One-third of all working hours for the breeder should be placed on the estrus estrus identification. The sow's estrus performance: inflamed vulva, vaginal fluid secretions; move around in the circle, frequent urination; nervousness, poor appetite; pressure back still standing; cross each other to accept the boar cross. There are also estruss that are not obvious. The most effective way to detect estrus is to use the trial boar for the trial of the sow.
