Pig transfer is the so-called foster care strategy.
If the number of piglets given birth by a sow exceeds the number of effective teats,
Then the amount of milk that the piglets can receive will not be enough.
At this time, the piglets can be transferred to the sow pen with a smaller number of litters.
To ensure that piglets receive adequate nutrition,
At the same time, foster care can also be allocated according to body size.
Improve the orderliness of the littermates.
