There are three methods for weaning piglets: one-time weaning, batch weaning, and gradual weaning.
One-time weaning method When the pig reaches a predetermined weaning date, the sow is separated from the sow. This method saves time, saves time, and is easy to operate. It is suitable for large-scale pig farms. When this method is used for weaning, the sow's feeding amount is appropriately reduced about 3 days before weaning. In order to reduce the environmental stress of the pigs, the sows should be transferred when the pigs are weaned, and the pigs should be kept in the originating bed for one week, and then transferred to the pig houses.
Batch weaning method Weaned according to the amount of food, body weight and physical strength of the pigs, generally the well-developed, large-volume, heavy-weight, robust pigs are weaned first, with poor development, low appetite, light weight, and weak constitution. Pigs are appropriately prolonged during lactation. Using this method will prolong the period of lactation and affect the number of sows per year. The nipples sucked by the weaned pigs become empty nipples and are susceptible to mastitis. However, this method of weaning is beneficial to weak pigs.
Gradually weaning method In the 3 to 4 days before the pig is expected to be weaned, the sow is rushed to the circle farther from the original circle, and regularly returns to let the pig feed, reducing the number of feedings on a daily basis and stopping breastfeeding on the scheduled date. This method can reduce the weaning stress on the piglets and sows, but it is more troublesome and is not suitable for sows and sows reared on the bed.
