Outdoor access and rooting substrate are among the highest-priority welfare provisions for commercially farmed pigs.
Outdoor access with genuine rooting opportunity addresses some of the most fundamental unmet needs of commercially farmed pigs. Rooting is not merely recreational — it is a core foraging motivation that pigs perform for hours daily when given appropriate substrate. Denying this drive in barren indoor systems causes frustration that manifests as redirected oral behavior including tail biting. Outdoor systems that allow pigs to root, explore, and engage with varied environments deliver the broadest positive welfare improvements and allow pigs to express natural behaviors that are effectively impossible indoors. Consumer support for pasture-raised pork makes these systems economically viable.
