The optimum mating period for oestrus sows

Sows are most suitable for mating 19 to 30 hours after the onset of estrus, or pressing the back of sows with their hands, while sows have the highest conception rate in 15 to 20 hours after standing still. The common method is that when the sow is in estrus, press the sow arm hard with both hands, such as the sow stands still and moves its tail to one side, exposing the vulva and removing the two hind legs to prepare for pressure, which is the best time for mating.
