Breeders Urged to Enrol Rams in CLA Monitoring Scheme 2007

The Sheep and Goat Health Schemes (SGHS) have launched the Caseous Lymphadenitis (CLA) Monitoring Scheme 2007.

This scheme provided assurance of freedom from disease to those buying breeding replacements.  Recent research has shown that vaccinating sheep against CLA does not provide the same degree of assurance since some vaccinated sheep can still become infected and spread the disease to other flocks. 

Ram breeders need to act now in order to present CLA Monitored stock at the sales this autumn.  The first step is to isolate the sale animals.  This must be done a minimum of twelve weeks before the first sale.  This is part of normal management practice in most flocks.  The next steps are to enrol in the CLA Monitoring Scheme with the Sheep and Goat Health Schemes Secretariat (telephone 01463 226 995) and arrange with your vet to collect the first blood samples and undertake a clinical inspection.  A second sampling and inspection are carried out a minimum of six weeks later.  The group will be awarded CLA Monitored status provided these results are clear. 


  1. The CLA Monitoring Scheme was first opened to flock owners throughout Great Britain in 2006 and was based on the pilot scheme operated at the Kelso and Lairg Ram Sales in 2005. In 2006 some 1,700 rams were sold as CLA Monitored in GB. Rams for sale at Kelso must be isolated from the 22nd June 2007 and those for Builth Wells from the 2nd July in order to comply with the rules of the CLA Monitoring Scheme.
  2. The CLA Monitoring Scheme 2007 is open to flocks in which vaccination is practised, provided the animals for which CLA monitored status is sought have not themselves been vaccinated.  This is because vaccinated animals will give a positive result in the blood test. 
  3. CLA is a bacterial disease of sheep and goats and the disease is now seen in several terminal sire breeds.  It is not yet widespread in hill and upland flocks.  Information on CLA will be provided by SAC staff on the SAC stand at NSA North Sheep 2007 on 6th June 2007 at North Hanging Wells, Bishop Aukland.
  4. The CLA Monitoring Scheme is supported by the sheep industry as an essential tool in the prevention of the spread of this important disease. This was agreed at a workshop held in March 2006 attended by 45 delegates.
  5. Flock owners who wish to test outside this Monitoring Scheme may do so.  Voluntary programmes in individual flocks to eradicate disease are available.  For further information on eradicating CLA from an already infected flock contact Graham Baird, SAC Veterinary Services (telephone 01738 629 167).
  6. The Sheep & Goat Health Schemes are operated by SAC and have an advisory board with representation from the National Sheep Association, breed societies and other industry representatives.
  7. The CLA Monitoring Scheme costs £8.00 (+VAT) per sheep monitored.  This covers the laboratory tests and certification.  The veterinary surgeon will charge for his visits to collect blood samples.
