Alastair observes that productivity and profitability are inextricably linked to lower emissions — and that smarter farm management, not silver-bullet technology, is the most immediate path forward.Here’s the main topics covered:
Methane intensity over total output — Alistair says producers should shift focus from total methane produced to methane per kilo of beef, making efficient, fast-growing animals the real emissions win.
Management first, technology second — Better reproduction rates, conception rates, and feed quality can reduce methane emissions right now, before investing in new genetics or feed additives.
Genetic research is advancing — Leading organisations like Angus Australia, Wagyu Australia, CSIRO, and the University of New England are developing research breeding values (EBVs) for methane.
Feedlots vs grazing — Feedlot cattle on high-quality diets produce significantly less methane than extensively grazed cattle on low-digestibility pastures, due to more efficient digestion.
Productivity = profitability = lower emissions — 75–80pc of profitability variation comes down to how many kilos of beef are produced per hectrare. More efficient producers are automatically more profitable, and, lower-emission — the three goals are inseparable.
