The default number of gestation days in AotG is 342, but this can be overridden at a herd and individual animal level.

If your herd averages a different gestation period you’d rather use, go to AotG >> Property and enter that number in the Gestation Days field.

This number becomes the new default for all new mating records, and will appear automatically when adding mating records.

You can still override this for individual animals—simply overwrite the default number with your own.
