Which identification system has been recently adopted to monitor pig movement?

The identification system that has gained traction for monitoring pig movement is the use of PIN/GIN tags. This method is effective because it allows for a unique identification number to be assigned to each animal, helping in tracking and managing their movements throughout various stages of production and transport. The identification system ensures accurate record-keeping, enhances biosecurity measures, and helps in tracing the origins of pigs in case of disease outbreaks.

PIN/GIN tags are particularly valuable because they can be easily read and are less susceptible to loss compared to some other identification methods. This is crucial for producers who need to maintain rigorous health records and comply with regulations regarding animal traceability.

In contrast, while RFID tags, barcodes, and microchips also serve identification purposes, the specific context of the question highlights the recent adoption of PIN/GIN tags, which may have aspects of implementation and regulatory compliance that are particularly beneficial for swine industry needs.
