Summary
This invited opinion paper, authored by prominent grazing scientists Provenza and Gregorini, argues that standardised, monotonous feeding regimens in contemporary food systems systematically constrain meaningful dietary choice for both livestock herbivores and human consumers. Drawing on behavioural ecology and grazing science, the authors contend that such constraints undermine nutritional adequacy and animal welfare. The paper proposes that dietary diversity and animal autonomy in food selection are foundational principles for optimising health and welfare across species.
Regional applicability
The findings are relevant to UK livestock farming and food policy, particularly regarding intensive confinement systems and standardised rations in dairy and intensive beef production. The emphasis on dietary choice and diversity aligns with emerging UK animal welfare standards and regenerative agriculture policies, though the paper's New Zealand-based perspective may reflect somewhat different grazing management contexts.
Key measures
Qualitative assessment of dietary choice availability; behavioural and welfare outcomes in herbivores; nutritional diversity and health implications in humans (as suggested by the opinion-paper format)
Outcomes reported
The paper examines how modern food systems restrict dietary diversity and autonomous food selection for both livestock and humans, as suggested by the title and journal context. It infers consequences for animal welfare, nutritional adequacy, and health outcomes across species.
