NECK TAG RUMINATION ACT
The NECK TAG RUMINATION ACT is a label that is attached to the cows neck and it determines monitors
the behavior of individual cows 24/7 and the system will detect the cow’s in heat. A cow in heat shows more
activity then being in a “normal” state of condition.
The main parts of the NECK TAG RUMINATION ACT for the purpose activity meaning heat – and health
detection are:
1. Cow activity detection together with the beacon VP4102
2. An acceleration sensor detecting motions.
3. A battery (active) assisted RFID (=Radio Frequency Identification) tag for individual cow activity
monitoring, operating on 433.6, 433.8, 434.0 and 434.2 MHz.
4. The 134.2 kHz inductive RFID tag (passive) is optional.
The motions of the cow are stored in the memory of the RFID tag transmitting this data. The repetition rate
of this transmission is min. 10 seconds and max. 10 minutes depending on the cow’s activity.
The antenna in the barn receives the activity information from the RFID tag of the individual animals and the
information is transported by means of the receiver VP4102 over CAN bus or Ethernet to the host computer
process controller and is e.g. used for ovulation/heat detecting, automatic cattle feeding, separation of
animals, milk registration etc.
The Velos program determines the activity increase of an animal. If an animal is a lot more active than usual
it will get an heat attention. The red light on the process unit will indicate this attention. The Velos program
displays overviews of animals with a clear increased heat attention on the PC screen.
Figures below show how the NECK TAG RUMINATION ACT is attached to the cow’s neck
NOTE:
The label can only monitor the behavior of the animals if placed on the cows neck in the right position.
Wrong Position of the label:
1. Back to front
Label attached backwards, the groove (and the arrow on the back of the label) is pointing towards
the cows body instead of the cows head.
2. Check position
Turned sideways on the neck or twisted on the collar.
