You can change the used boar for a sow’s mating event.
Open the Animal History for the sow whose mating event you want to change.
Click on the mating event for which you want to change the boar.
Go to the Boar field and select a different boar from the list of available boars.
You can also enter a custom boar, if the settings allow it.
Then click “Save.”
Keep in mind that if you've mated a sow twice, you may need to change the boar for both events.
