The Australian Limousin Breeders’ Society have released a new index, the Sustainability Selection Index, in conjunction with the July 2025 Single-Step Limousin BREEDPLAN analysis. This brings the total number of selection indexes available for the breed to six.

The Sustainability selection index estimates the genetic differences between animals in net profitability per cow joined for a self-replacing commercial herd targeting the domestic supermarket trade with a greater emphasis of sustainable livestock production. Selected heifers are retained for breeding and so maternal traits are of importance. Steers and surplus heifers are finished on grass or a short fed grain program. Steers target 450 kg live weight (250 kg carcase weight & 8 mm P8 fat) and heifers 425 kg (235 kg carcase weight & 9 mm fat depth), at 15 months of age. In response to industry feedback; positive emphasis has been placed on the ability to meet MSA specifications.

With the release of this new selection index, the six selection indexes available for Australian Limousin are the:

• Domestic Maternal Index
• Sustainability Index
• Export Maternal Index
• Northern Export Index
• Yearling Prime Index
• Dairy Beef Index

Further information about these selection indexes is available from the BREEDPLAN website here.
