OUR DAILY BUSINESS EXPERIENCE
In our daily business in Holland and Denmark we now and then see challenges with getting Cow ID
This presentation is based on information’s and views from sporadic observations reported by our field- and validation staff.

COW ID-TOPICS RELATED TO MILKINGAND MILK RECORDING
• Animal ID is the first critical challenges when collect data from sensor’s in a milking system.
• Sensor data is only valid and relevant when linked to an valid ID
• To ensure correct and true data, it is essential to have firm routines and technology to catch Cow ID

COW ID AND DATA IS AN ISSUE OF GREAT CONCERN
• Milking parlours with increasing throughput gets more and more automation.
• Milking system gets more and more sensors for constant measurement on a series of parameters.
• Therefor it gets more and more important to highlight the Cow ID topics

DO WE….
• Milk cows and collect sensor data?
OR
• Milk ”transponders” and collect sensor data?

COW ID WITH RFID OR TRANSPONDER
• Both types have the same issue with accurate Cow ID
• The herd management system on the farm need to be set up with Cow no. and Transponder no. and Official animal number.
• Transponder at neck/leg band normal is put on heifers just before or just after calving
• RFID ear tags are normal put at new born calf just after birth

WHAT IS ACCURATE COW IDENTIFICATION?
• Reading all cow with a transponder passing the antenna at the entrance of the milking parlour!
OR
• Cow number on the milking point display is the same cow physically standing at that milking point!

CHALLENGES ON DATA COLLECTION
• Large variety in distribution of milking technology
• Portable meters are aging – some really old
• Sampling process not satisfactory
• Too much manual work
• Too many possible sources of errors
![Page 11: Challenges of getting cow ID - | ICAR - Jon… · •RFID ear tags are normal put at new born calf just after birth 8...| WHAT IS ACCURATE COW IDENTIFICATION? •Reading all cow with](https://reader036.vdocument.in/reader036/viewer/2022071215/6044fde163c2f534ee2f09c3/html5/thumbnails/11.jpg)
MAIN REASONS BEHIND ERRORS
• Cows without electronic ID
• User/Milker not familiar with the system
• Milker do not follow SOP for the system
• Cows pushed into the parlour
• Cows passing each other after identification
• Malfunction of installation
• Lack of maintenance of the electronic installation
• Electronic noise from other source
• Poor installation of electronics and wires

BIG PARLOURS –HIGH THROUGPUT
• Validation of ID at bail and row is critical
• One missing cow ID is not only a problem for the individual cow.
• All bails after that cow might have wrong Cow ID

TAKING HOME MESSAGE
Core value of any registration, whether manual or automatic, is to monitor, control and validate
Cow ID
