The next stop is the next event, which is weaning, the 18 piglets were weaned.
The next cycle will start only at the next mating, which marks the end of the current cycle and the beginning of the fourth cycle of this sow.
Note that the system shows the IBWM days (interval between weaning and mating) ending cycle 3 and cycle 4 starts on the same date.
