If you, by accident, entered the wrong sow number when entering a new animal, you can delete it again. To do this you open the sow card from the “Sows/boars” menu and choose “Sow card”. Here you search for the sow card you made by accident and click on “Delete sow card”, marked by the green circle on the picture below: 




Then a warning window appears on your screen, where you must enter the sow number, in this case “11113” and then click “Ok”.  




The sow card will now be deleted and you can create the correct one.
