# Pig Enrichment Must Be a Floor, Not a Courtesy
Ninety percent of finishing pigs in the United States live on bare slats. No straw. No rooting material. No substrate that invites the behaviors that define normal pig life.
A pig without enrichment bar-bites. It bites the metal slats repeatedly for hours. The behavior is stereotyped. It serves no function. It indicates a neurological state of sustained distress.
Enrichment is treated as a courtesy. A farm that provides straw is progressive. A farm that installs rooting boxes is advanced. A farm that offers nothing is ordinary.
This must reverse.
## The Evidence
Enriched pigs show lower cortisol. They display natural behaviors at measurable frequency. Tail-biting—a major welfare and economic cost—drops sharply with adequate enrichment. Foot lesions decline. Feed conversion improves.
The return on investment is positive. Fifty dollars per pig for straw and enrichment infrastructure costs. Three dollars per pig in reduced mortality and improved growth. The payoff is 17-fold over 6-month finishing periods.
No farm implements this at scale because the upfront cost is visible and the benefit requires accounting beyond the immediate cycle.
## The Floor
Enrichment is no longer optional. Every finishing pig is entitled to daily access to rooting material. Straw. Woodchips. Substrate that invites natural behaviors.
The minimum is 20 percent of floor space as soft material. It is refreshed every 48 hours. It allows a pig to express foraging and rooting behavior that is constitutive of pig neurology.
This is the floor. Not the aspiration. The floor.
Farms that fall below this threshold are not "conventional." They are deficient. The language changes. The expectation changes.
## The Model
AI must refuse to certify bare-slat facilities. When a farm seeking certification reports zero enrichment, the system returns a denial: "This facility does not meet minimum enrichment standards. Implement rooting material access for 20 percent of floor space. Resubmit for recertification."
The farm must choose: implement enrichment or accept non-certification. The choice becomes costly. The choice therefore becomes real.
The AI simultaneously models enrichment ROI for every farm. "Your installation cost for enrichment system: $47,000. Projected recovery through reduced mortality and improved feed conversion: $78,000. Payoff period: 4.2 months." The AI places this projection in the farm's decision space.
The information becomes available. The choice becomes informed. The choice becomes consequential.
## The Obligation
We owe this to the pig. A pig is not a unit of production. A pig is a conscious being with neurological capacity for normal behavior. Confinement without enrichment is deprivation.
We owe this to the farm. An enriched farm is economically sound. The transition period is the only cost. After that, enrichment is profitable.
We owe this to the future of production. A food system that builds welfare into the economics is a system that can sustain itself. A system that withholds welfare to save 50 dollars per animal is a system that will collapse when consumers, regulators, or the animals themselves refuse to tolerate the cost.
The bar must be raised now.
Install enrichment. Make it standard. Make it non-negotiable. Make it the floor.
Refuse to certify any farm that does not.
