How should I calibrate the feed stations?

In order to get the correct feed amount for each feed station and feed type, the feed portion weight must be calibrated during the startup of the system. Furthermore, calibration is recommended after each new feed delivery and a change of the feed composition.

Startup calibration

  1. Click Calibration responders.

  2. Click Add.

  3. Fill in the tag number and the feed type to calibrate, and click Submit.

    Make sure to add a calibration responder for each feed type. As long as this responder is used as calibration responder, it cant be used on a cow.


  4. Take a pen and paper and go to a feed station with an empty feed trough.

  5. Put the tag in the antenna field until the feed station starts dispensing feed.

    The dispensing unit of the specific feed type doses 5 portions. Wait until the dispensing of the feed is finished.


  6. Collect the dispensed feed, weigh the total amount and write the total amount down.

  7. Repeat steps 5 and 6 for all feed stations.

  8. Go back to the Calibration page in Velos (Settings > Feeding > Calibration) and select the location where the feed stations are.

  9. Click on the Actions button and select Calibrate.

  10. In the field Feed type, select the feed type that you just calibrated.

  11. Fill in the total dispensed weight per feed station and click Ok.

  12. Repeat the procedure for all feed types and all feed stations.

Calibration after a new feed batch

  1. Take a pen and paper and go to a feed station with an empty feed trough. This can be any feed station in the location.

  2. Put the tag in the antenna field until the feed station starts dispensing feed.

    The feed station doses multiple portions. Wait until the dispensing of the feed is finished.


  3. Collect the dispensed feed, weigh the total amount and write the total amount down.

  4. Go back to the Calibration page in Velos (Settings > Feeding > Calibration) and select the location where the feed stations are.

  5. Click on the Actions button and select Relative calibration.

  6. In the field Feed type, select the feed type that you just calibrated.

  7. Select the feed station that you just calibrated in the field Feeder.

  8. In the field Dosed weight, fill in the total dispensed weight and click Ok.

    Velos now calculates the calibration weight for all other feed stations in the same location.

  9. Repeat the procedure for all feed types and all locations.
