(2) Fostering time The optimal time for fostering piglets is 1-2 days after giving birth. This is mainly because at this time, the piglets can't discriminate odors, and there is no biting phenomenon between sows that bite piglets or piglets. Usually pigs are to be kept at night. (3) Method of fostering When the rearing piglets are fostered in the first-migration nest, they must be placed in large-scale piglets. When the first-born piglets are fostered in the nests, they should be fostered. (4) Eliminating the smell of piglets The pig's sense of smell is particularly sensitive, and the maternity recognizing mainly depends on the sense of smell. When fostering, the sow must be able to discriminate the odor of the foster piglets in order to foster success. The first method is to wipe the whole body of the piglets that are to be fostered with piglets that have been placed in their nests, such as the sow's placenta, and then rub them in the receiving box for about 1 hour to remove the odor. The second method is to spray Suer water into the delivery room to eliminate odors. (5) Observe that in the first few days of foster care, it is necessary to observe carefully whether the sow is receiving the foster piglet, and whether the piglet in the foster nest should accept it. If sows bite between the piglets or piglets, they should be separated in time, re-treated according to the foster method described above, and then fostered.
