At Macquarie Wagyu, data is more than a record of past performance. It is one of the tools that guides each breeding decision and helps us keep improving across generations. Every carcase result is recorded and analysed, including the results that sit at the very top end of the marbling scale. Under the AUS-MEAT grading system, any carcase assessed beyond Marble Score 9 is recorded as 9+. While that is an important benchmark, it can also group together animals with meaningful differences in marbling performance.

To better understand those differences within our own herd, Macquarie Wagyu assigns a numerical value of 10 to all 9+ results in our internal, independent carcase analysis. This allows us to calculate more accurate marbling averages and ensure elite-performing animals are properly reflected in the data.

These details matter. At the highest levels of Wagyu production, small differences can shape the next generation. By recording, analysing and applying this information, we can make more informed selection decisions and continue building genetics with greater consistency, predictability and long-term value.

Figures marked MW Marbling Average across this website are drawn from Macquarie Wagyu’s internal carcase records and are updated as new results become available. Published breed database figures may differ depending on submission timing and available records.
