Either via an icon that will be on your main PigVision screen or you can find it in the Report menu. The E-Control report is available for both the breeding and feeding herd sections. The reports can show month on month performance but also the last 1,3,6 and 12 months depending on stocktakes you have entered into PigVision.
You can check and change the sections that will show on the E-Control Report by going to the Production Report option in the General menu.
