The 2025 drop SWS Sire Evaluation wethers were processed on 21 April at Gundagai Meat Processors, joined by a big team of keen onlookers including the SheepMetriX team, James Burge (host producer), Davo Weir (SWS SE Committee member), Lisa Haylock (CSU Placement Student), Sarah Preston (SwabTec) & Grant Burbidge (Burbidge Farms). Thank you to all these volunteers for your time and effort! A comprehensive range of data was collected, including IMF (Intramuscular Fat), LMY (lean meat yield), carcase weight (CWT), and liveweight plus much more, providing valuable insights into sire performance.
A big thanks also to Jake Bourlet & Emily Stewart from Gundagai Lamb for all your help!
Alongside this, 150 random gut samples were taken, with abomasum lining scrapings collected to support and validate the work from SwabTec. This research is investigating worm resistance using saliva samples, and these additional measurements will help strengthen the findings.
