How natural grazing behavior shapes cattle welfare needs and the welfare implications of systems that restrict or eliminate grazing time.
Grazing is not merely a feeding method for cattle - it is a complex behavioral system involving locomotion, social interaction, and environmental engagement that occupies the majority of active daily time. Cattle denied grazing access in zero-grazing systems are deprived of this entire behavioral complex, not just a feeding opportunity. Evidence shows that cattle with outdoor access and grazing time show better welfare outcomes including lower lameness, reduced stereotypic behaviors, and behavioral indicators of more positive states. Climate and land availability create genuine constraints on grazing access in some systems, but where possible grazing remains an important welfare standard.
