None of the pigs on the farm have names.
They have numbers in a database, and they’re tracked with a tag that’s punched through their ear.
When the pigs eat and drink, they’re scanned.
That ensures they’re eating and drinking enough.
When it’s time to harvest a pig, they’re scanned into the processing system and the tags are pulled out of their ear.
The tags are reprogrammed to new numbers, punched through new pigs’ ears, and the cycle begins again.
The farmer tracks everything.
Until the farmer is harvested, their ear tag removed, and it’s allocated to a new farmer.
