It is best to set up a special delivery room for sows, which is required to be warm and dry, with a humidity of 65%-75%, comfortable and quiet, sunny, fresh air and a temperature of 22-23 ℃. For the sows with good body condition and breast development, the diet should be reduced from 3 to 5 days before delivery, which should be gradually reduced to 1 × 2 or 1 × 3 of the feeding level during pregnancy, and the green succulent feed should be stopped.
