Migrating Microchips

Meet 'Phoenix':

Here is an anatomical depiction of where each of the twelve microchips were implanted. Below is a color coded key with descriptions of each chip location.

Implanting the Microchips

A horse with no history of gastrointestinal disease underwent a ventral midline celiotomy to implant twelve bioinert microchips into the subserosa at predetermined locations within the large colon and cecum.

Data Collection

A RFID (radio-frequency identification) scanner was used to monitor the location of the colon via transcutaneous identification 1-5 times daily for a one-month period.

Necropsy

Following humane euthanasia, postmortem examination of the horse was performed to assess microchip implantation sites for migration and histologic assessment.

So How Does it Work?

Above depicts a video of a typical scan that was performed 1-5 times daily at various times in relation to meal status.
