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.

Assessing a ram’s genetic merit is key when looking to maximise profitability within the flock and accelerate growth from forage

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.

AHDB are delighted to share news of our involvement in “Breed for CH4nge” an industry collaboration that will help the industry to breed sheep with a naturally low carbon footprint. There are a number of exciting elements to the project that align closely to AHDB’s research interests, and the genetic services delivered by Signet. The project will enhance our knowledge of genomics, breeding for parasite resistance and CT scanning, whilst assessing the benefits of using Portable Accumulation Chambers (PAC) to predict methane emissions in grazing sheep.

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.

Signet are proud to announce the release of the UK’s first commercially available genomic breeding values for sheep. The release of genomic breeding values is a major first for the UK industry following research lead by Samir Id Lahoucine at SRUC; work was funded as part of the Hybu Cig Cymru (HCC) lead Hill Ram Scheme and has been implemented as part of Farming Connects Welsh Sheep Genetics Programme.

The Rossiter family claimed over champion female with lot 212, Huish Florence sired by an Australian import ram. This was the highest index female within the sale and ranked within the top 5% of the breed for Terminal Sire Index and Maternal Index. This September born ewe lamb then went on to achieve highest price female at the sale, selling for 1200gns to Jeremy Durrant’s Hydes flock.

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).

Join Signet Breeding Services for the annual results update from the RamCompare project’s UK progeny test, with updated results from the year seven data collection.

For the first time results will be released online as 38,500 abattoir records from 400 RamCompare sires are incorporated into the National Terminal Sire Evaluation. SRUC’s new breeding index will be launched as the project steps up a gear and makes abattoir derived breeding values more widely available.

AHDB are keen to support performance recording flocks based in England that wish to use SRUC’s CT scanning service.

AHDB will provide a support payment to SRUC of £55/lamb to support CT scanning services. Breeders can chose to take their lambs to Edinburgh or go to one of the mobile venues set up by SRUC. In 2023 AHDB are placing an additional criteria on breeders that wish to receive funding for CT scanning, which is that CT scanned lambs that are performance recorded with Signet must be genotyped (using a 50K genotype).
