In recent years there has been an increasing number of breeders have had their lambs measured using Signet’s ultrasound scanning service as part of their breeding programmes. It is a great tool to identify sheep with superior muscling, while avoiding those likely to be excessively fat. This is the best way of identifying animals with superior genes for muscling and this data is used to produce Estimated Breeding Values (EBVs).

Scoping study: Delivering a vision for improving the beef and sheep sectors through animal breeding over the next 10 years.
The report presents evidence to inform decisions related to the development of the genetic improvement infrastructure for the UK sheep and beef sector, in order to improve financial sustainability and reduce environmental impact of the sector, including the current financial benefit of genetic improvement.
Record prices achieved at virtual ram sales
During the summer, we launched some new estimated breeding values (EBVs) for sheep farmers. To explain what these were and how useful they could be, we hit the road to talk to farmers about them at a series of workshops.
Farmers attending the workshops heard how careful ram selection can easily lift the value of lambs by £3–£5 a head, which would be worth an extra £1,000 over a ram’s working lifetime.
The role of genetics when selecting for profitability and growth from forage
Assessing a ram’s genetic merit is key when looking to maximise profitability within the flock and accelerate growth from forage
Measuring methane emissions from individual sheep, an update from SRUC.
Results from preliminary trials of the new PACs owned by SRUC support research findings from New Zealand, Ireland and other countries: methane emissions from sheep are feasible to measure on-farm using Portable Accumulation Chambers (PAC) under UK conditions and that there is variability between animals in methane emissions recorded by PACs that could potentially be exploited within breeding programmes.
Economic Expression of Hill Index
Performance recording has been used within hill sheep breeding programmes for many years, but recent developments as part of the Hill Ram Scheme in Wales has led to changes in the expression of the index. From June 2023 the index will be expressed in £ as the expected annual return per ewe.
New breeding values for abattoir traits revealed by AHDB’s Signet Breeding Services
The Agriculture and Horticulture Development Board is to make new breeding values for abattoir traits an integral part of the National Terminal Sire Evaluation through its Signet Breeding Services, following significant analysis of abattoir data. This new approach coincides with the release of the latest RamCompare results at a webinar on 11 May 2023 (book online).

Gortleigh - 35 years of recording
The Gortleigh Dorset flock was established by Gill and Richard Trace in 1986 on a 330 acre farm in North-West Devon. The breed was chosen for its ability to lamb naturally out of season, its versatility, adaptability and docility.
The Gortleigh flock has always been pro-actively managed using Estimated Breeding Values (EBV’s) and has been a member of the Centurion Dorset breeders group since 1997.
Should I only breed from rams that are born as a twin?
At a recent meeting, commercial farmers with Dorset sheep were discussing how important it was to select a ram that has been born as a twin.
Breeding for worm resistance in sheep
In Autumn 2022 ten performance recorded hill flocks measured their lambs, assessing both individual FECs (for Strongyles and Nematodirus) and an immune response to worm challenge that is measured via blood samples, referred to as IgA. Measures were taken by farmers and vet and then assessed by Techion (for FEC) and Biobest (for IgA).
