Zero-grazing (indoor confinement) dairy systems present significant welfare challenges requiring careful management to compensate for the absence of outdoor access and natural behaviour opportunities.
Zero-grazing systems remove the fundamental welfare benefit of outdoor access - freedom to express natural foraging, locomotion, and social behaviour. Compensatory welfare measures including excellent lying surfaces, cubicle design, environmental enrichment, and careful nutritional management can partially offset this deficit but cannot replicate pasture access. Welfare in zero-grazing systems is entirely management-dependent and requires higher vigilance and investment to achieve equivalent outcomes to pasture systems.
