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.

CT Scanning Dates and Locations for 2020

Information will appear here when confirmed
Please note that the mobile scanner will be provisionally booked for these dates but, as usual, we need to have a minimum of 100 lambs over 2 days for each scanning session with the mobile scanner. Numbers at Edinburgh are more flexible. Please note, any eligible breed can be scanned on any of the dates above providing SRUC is notified in advance.

CT Scan Charges

CT scan charges are normally subsidised by the relevant bodies in England, Scotland and Wales.

Unsubsidised charges are as follows:

  • Edinburgh – £70/lamb
  • Mobile Site – £97/lamb

The subsidy will apply to male lambs only and will be for a minimum of 5 lambs per flock, with a selection of sires represented. Please note their have been changes to CT subsidy for 2019.

AHDB funding in England

AHDB are keen to support breeders that wish to use SRUC’s CT scanning service and in 2019 we will launch six new breeding values for CT derived traits to add more value to the measurements collected. However, due to budgetary constraints across AHDB’s programme of research activity, we are much more limited this year in the amount of support that we can provide to individual breeders.

In our attempt to be fair to all ram breeders, we will continue to offer the same level of support (£55/lamb), but we will be restricting funding to a maximum of 8 ram lambs per flock. Funding in 2019 will also be restricted to those breeds included in the new Terminal Sire Breeding Evaluation.

As in previous years, the subsidy is only available to fully recorded ram lambs. It is recommended that flocks send a minimum of 5 lambs per flock, with a selection of sires represented.

Funding for 2020 yet to be confirmed.

QMS funding in Scotland

In 2019 QMS paid for 50% of the CT cost per lamb to a maximum of 15 lambs/flock or 10 lambs per flock where a breeder is scanning multiple flocks.

HCC funding in Wales

Awaiting confirmation but expected to be similar to QMS.

The SRUC CT unit are more than happy to scan additional lambs for any flock, so please do discuss your requirements with Kirsty McLean; email: [email protected] or telephone: 0131 535 3250 / 3251


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
  • Lambs should be around 17 – 24 weeks of age at CT scanning. Younger lambs must be well grown (around 40kg)
  • 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
  • Lambs withdrawn 10 days before the scan date will be charged at the full unsubsidised rate
