After at least 21 days of milking data collection, the Auto Calibration data becomes available in Velos. A warning
is shown when not enough milking data is collected yet, including an expected delivery data for the auto
calibration data.
Conditions
All of the following conditions must be met to enable the use of this test. When not all conditions are met, this
test cannot be used.
• The weights measured by the bulk tank must be weighed by a calibrated measuring instrument.
• Only milk from the milking parlor with SmartFlows ends up in the bulk tank.
• The non-delivered milk yield can be properly estimated: The amount of milk that has flown through the
SmartFlows and has not been delivered via the bulk tank (for example when there is a milk tap on the farm
or when some milk is used for own consumption or for feeding calves).
• There must be accurate animal identification in the milking parlor.
• The animals are sufficiently mixed over the different milking points.
• The Nedap equipment in the milking parlor (animal identification and all SmartFlows) must have functioned
without any problems or changes for at least 21 days , so that the data are representative and reliable.
Procedure
1. In Velos, go to Settings > Milking > Smartflow settings.
2. Select the milking parlor.
3. Go to the tab Auto calibration.
At initial start-up the bulk tank correction factor field is empty.
4. Click on the Update bulk tank information button.
The Delivery period window opens:
The delivery period is the milking period that is used for the calculation of the bulk tank correction
factor. The milk yield registered in Velos during this period is used in the calculation. The delivery period
preferably has a length of at least 6 days or includes at least 2 milk deliveries. The exact date and time
can be found on the delivery note of the milk factory.
a. Enter the start date of the delivery period.
b. Enter the end date of the delivery period.
c. Enter the bulk tank yield that is reported by the milk factory.
d. Enter the non-delivered yield (see Conditions (page 31)).
e. Click Submit.
5. The proposed correction factors for each milking point are calculated and the deviation between the current
and newly proposed factors is shown.
6. Click on the Submit button to save the correction factors:
a. A warning is displayed. Confirm your decision by clicking on Submit.
4.4.2 Milk test
Conditions
• The milk that must be collected must flow through the SmartFlow before it is collected by a milking bucket.
• Weigh the collected milk with a calibrated ICAR approved weighing scale. See the ICAR documentation for
more information.
• Collect the milk from at least 8 cows per milking place. If strange or extreme milkings are found in the
collected milkings, collect the milkings from more cows.
