Summary
This paper, authored by leading researchers in sustainable livestock systems, examines the efficiency of Irish livestock farming in converting feed resources into human-edible protein. By accounting for the protein content of feed inputs relative to protein outputs in meat and dairy products, the authors assess the net contribution of livestock to protein supply—a critical metric for evaluating the sustainability and nutritional role of pastoral farming systems. The work integrates agronomy and nutrition perspectives relevant to intensifying debate about livestock's role in food security.
UK applicability
Highly applicable to United Kingdom farming policy and practice, given comparable pastoral systems, climate, and regulatory frameworks. The methodology and findings would inform UK debate on sustainable protein production and land use efficiency in livestock farming.
Key measures
Net edible protein contribution; feed conversion ratios; land use efficiency; edible protein inputs versus outputs
Outcomes reported
The study quantified the net contribution of Irish livestock (particularly dairy and beef) to human edible protein supply by accounting for feed conversion efficiency and land use. It assessed whether livestock production generates a net gain or loss of edible protein available for human consumption when accounting for feed inputs.
