The South Australian Merino Sire Evaluation sites commenced in 2017 and is supported significantly by Merino SA. The aim of the site is to make an important contribution to genetic improvement for Merinos in SA and is the only trial of its kind in the state.
Keyneton Station, Keyneton hosted the inaugural trial in 2017 and again in 2018. Since then two years of trials have run at McPiggery, Lameroo; the Eckert Family at ‘Mentara Park’, Malinong; and has remained at Turretfield Research Centre, Rosedale since 2024. Turretfield Research Centre receives an average 425mm rainfall in a winter dominant pattern. Their ewes are purposely bred from Leahcim and Mernowie bloodlines to be highly fertile, plainer bodied and they are a good expression of South Australian Merinos. They have a mature weight of 75-85kg and produce approximately 19 micron wool at 60% yield depending on the season.
Rams will be capable of producing progeny with 18-21 micron fleece at 12 months with at least 4kg of wool from 8 months growth from an easy-care plain bodied sheep. In addition, progeny should be capable of achieving 22-25kg carcase weight at 10 -12 months of age. Ewe progeny will be capable of high natural conception rates when first mated at 18 months.
