RamCompare project open for pedigree nominations

Pedigree breeders have the opportunity to receive valuable information on their sires’ progeny by nominating rams and semen for use in the RamCompare project.

RamCompare is the UK’s first commercial progeny test, using data from throughout the supply chain to inform genetic evaluations. It aims to enable the UK sheep industry to drive genetic improvement through the inclusion of commercial data in genetic evaluations.

Animals that are involved in the project now have new estimated breeding values (EBVs) available covering carcase weight, fat and conformation. These EBVs can be used when marketing these rams.

By taking part, breeders will receive feedback on the performance of their rams for commercially relevant traits.

Bridget Lloyd, RamCompare Project Coordinator, said: “This is a great opportunity for breeders to contribute to an important industry project while receiving useful information on their stock, which they can use to promote their rams.”

Alwyn Philips, pedigree breeder, said: “RamCompare provides a great way for flocks to benchmark performance in an unbiased, commercial environment. It also provides an alternative shop window to show customers what genetics really can do.”


  • For breeders who want to nominate semen, there is a minimum requirement of 30 doses for use via artificial insemination (AI)
  • With the introduction of a unit at the Agri-Food and Biosciences Institute (AFBI) in Northern Ireland, the project team is also looking for Suffolk or Texel semen eligible for export. For semen with EU export status, 40 doses per ram is required.
  • For natural service sires, fit and fertile rams are required, with preference given to rams that are shearlings or older
  • Rams must have EBVs in the top 20% of the breed
  • There must be a good history of performance records of the ram and its progeny (e.g. ultrasound scan, computed tomography (CT) data)
  • The ram must be a shearling in autumn 2018, or older
  • It must have good and known health status and be from a Maedi Visna-accredited flock
  • The ram must come from a flock with good genetic linkage to other flocks
  • It must be part of a Signet-recorded flock and provide genetic diversity to the rams that have already been used in the RamCompare project

How to get involved

Nominations are now open and close on 5 March 2018. For nomination forms visit Ram Compare or contact Bridget.Lloyd@ahdb.org.uk.
