 | | The number of gilts in the pool must be large enough to cover the sows culled for poor performance, structural or reproductive unsoundness, non-cycling, or poor conception. |
 | | The size of this gilt pool depends on: culling rate of sows, conception rate of sows, conception rate of gilts, percentage of gilts cycling normally, percentage of gilts cycling per day, and length of breeding period. |
 | | The farrowing process is a new experience for a gilt, and her instincts are not adequate to handle the trauma of birth in some cases. |
