Computed Tomography

CT provides a welfare friendly way of assessing the total muscle, fat and bone yield in a live sheep. This near perfect predictor of carcase composition can also be used to measure the muscling in different parts of the carcase, such as the rib, loin and gigot.

Why CT scan your lambs?

  • CT scanning will increase the accuracy of Estimated Breeding Values (EBVs) produced for growth and carcase traits.
  • Where CT measures prove an individual or family to be genetically superior their indexes and EBVs will increase.
  • CT images can be used to assist the marketing of recorded rams.

Are your lambs eligible for CT scanning and the relevant subsidy?

  • A minimum of 5 lambs from each flock is required to allow evaluations to be as accurate as possible.
  • Only male lambs are eligible for subsidy but we are happy to scan both males and females
  • Lambs must be starved for a minimum of 4 hours before scanning
  • Ideally lambs should be back-fat scanned before they come for CT and a selection of sires should be represented in the group of lambs you bring for CT scanning.
  • Lambs should be around 40kg weight at CT
  • Mobile sites have been booked for a minimum of 2 days at each session. We must have 50 lambs per day, booked in for scanning, to enable a session to go ahead
