Outdoor access for livestock provides opportunities for natural behaviour including grazing, rooting, and movement that indoor systems cannot replicate, with significant welfare benefits.
Outdoor access delivers welfare benefits that cannot be fully replicated indoors: fresh air, natural substrates, complex environments, and the full expression of grazing and rooting behaviours. The welfare benefits of pasture are not merely additive but structural — they change the fundamental nature of the animal's experience. Challenges include extreme weather welfare, predation risk, and biosecurity management. Seasonal access combined with high-quality indoor housing for adverse conditions can deliver most welfare benefits while managing practical risks. Consumer demand for outdoor and pasture-raised products provides the economic signal that makes outdoor systems viable.
