As one of the founding Merino Sire Evaluation sites the Macquarie Sire Evaluation trial aims to evaluate and promote current industry sires suited to the wheat/sheep zone of Central New South Wales. The trials are managed by the Macquarie Sire Evaluation Association and NSW DPI.
Trials have been run on various properties in the Macquarie region of NSW since 1989 and are currently run on the Trangie Agricultural Research Centre (TARC), where a Merino Lifetime Productivity project (MLP) site is located.
Field Days and information days are held regularly to promote the outcomes of the sire evaluation trials and as a transfer of information between sheep breeders, researchers and third-party providers.
