Zero grazing systems where grass is cut and brought to housed cows offer potential benefits in efficiency but raise questions about welfare compared to systems with outdoor access.
Zero grazing removes the welfare benefits of pasture access including natural locomotion, UV exposure, and environmental enrichment through grazing behaviour. Compensating for these losses requires excellent housing with cubicle comfort, enrichment provisions, and positive human-animal relationships. Welfare outcomes in zero grazing depend critically on management quality.
