Within our terminal sire breeding programmes we are often asked to put a commercial value on the genetic improvement we make in enhancing growth rate and conformation. While it is relatively easy to understand the value of increasing a lamb’s carcase weight, carcase conformation grade or changing fat classification, it is far harder to determine the impact of reducing days to slaughter.

The Kelsey trophy is awarded to a Signet recorded Hampshire Down flock who has made the greatest genetic gain this year. This year it has been awarded to the Bridgehaugh flock, the flock has an impressive Terminal Sire index flock average of 287, putting the lambs within the top 5% of the breed.

With farmers facing ongoing uncertainties including changes to basic payments and increased pressure to reduce carbon emissions, many suckler farmers are investigating ways to improve the efficiency of their cattle enterprises. Could AHDB's new maternal breed evaluations be the answer? Dr Alex Brown, AHDB's Senior Beef Breeding & Genetics Manager, explains more.

Utilising technology to make informed breeding decisions and identify animals with superior muscle across the carcase can increase carcase yield and the profitability of sheep enterprises. Laura Eyles, Senior Signet Breeding Specialist, explains how levy funded research and investment in the late 1990’s has allowed this world leading technology to be used within our sheep industry.

The Lincoln Red Cattle Society have recently announced their intention to provide all their members with free access to Signet’s services. As part of this new initiative with Signet, the Lincoln Red Cattle Society will fund the recording costs of any paid up Society member; effectively removing the financial barrier that may have previously limited smaller herds from engaging in weight recording.

In this episode of the Food & Farming podcast, our Signet Breeding Manager at AHDB, Samuel Boon, talks through the role of CT scanning when making breeding decisions, whilst Signet consultant Laura Eyles speaks to Kirsty McClean and John Gordon from SRUC to find out the how and the why.

Different animals are known to react differently to changing climatic and weather conditions, and part of these differences may be genetic. Therefore, breeding for enhanced animal resilience to climate change has been proposed as a possible mitigation strategy. 

The aim of the present project was to examine the genomic profile of climate resilience in sheep, with a focus on identifying the desirable genetic profile of animals whose performance and growth do not change because of changing weather. 

To meet the needs of the commercial producer, ram breeders must select rams with the right carcase attributes, and this can be aided using EBVs to identify genetically superior animals. In order to assess muscling in the live animal, breeders can utilise measurement services such as ultrasound scanning and Computed Tomography (CT) scanning within their breeding programmes to find the best animals and make informed decisions

Commercial producers are seeing the benefits of looking deeper into an animal’s background before purchase and utilising data to make informed decisions rather than buying on looks alone. Many buyers are seeking high index terminal sires to improve their farm’s profitability; improving carcase conformation, reducing days to slaughter and increasing the value of the lambs sold

In the UK the Poll Dorset/Dorset Horn is well known for being an aseasonal breeder, capable of breeding out of season, with lambing frequently taking place in September and October.

At Signet we are interested in the genetic influences upon seasonal breeding and are greatful to Liz Nabb for completing a comprehensive mini-project on the seasonality of reproduction as part of her AHDB funded PhD.
