Combination and foster care of piglets

In the case that the litter number is more than the nipple number of sows, there is no milk after sows, and sows die, the method of foster care can be used to save piglets without milk to eat. First, the piglets to be farmed are mixed with other piglets, or coated with the sow's urine. The second is to try to find sows with the same delivery date for foster care. Third, first-born sows should not be farmed with more than 10 piglets. Fourth, do not foster piglets with dysentery. Fifth, do not foster piglets that have not eaten colostrum. The sixth is to mark the pigs and observe whether they are breast-fed or not.
