If you need to account for your use of fertilizers, PigVision can calculate this.
You can see the use in your e-control. If you want different dates, you will have to make status for these dates.
Select the tab “Management” and select “Farm list”. Todays date will be shown but you can click on the calendar and select the desired date.
Here the first of July 2022:
Klick “Ok” and the farm list will be calculated.
Select the tab “Inventory” (red) and enter the numbers in your inventory using the correct date. (Inventory is found here: “Sows/boars” – “Stocktake”.
Attention: If you put in data back in time, you will have to change the validations in the programme. As a standard it is not possible to enter data more than 220 days back in time.
Go to "General" - "Setup" - go to the tab "Validation"
If you are going to put in data on both sows and growers back in time, both "Min." boxes should be corrected to say -9999.
Note that this should be changed back to the default values, when you are done putting in data back in time.
Repeat the procedure with the new data using the calendar marked blue:
Now you can see the amount of fertilizer spent in your e-control.
