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. 

RamCompare year six results have continued to show the correlation between Estimated Breeding Values (EBVs) in terminal sires and commercial productivity in lambs.

Signet’s Shear Force research has also proven that the animal’s genes do influence tenderness and that measurements of tenderness can be used to produce breeding values.

RamCompare uses nominated performance-recorded rams from many breeds on commercial farms across the UK. RamCompare’s year six results demonstrate how rams with key breeding traits can optimise flock profitability. In four case studies flock profitability was enhanced by £1.98 to £5.17 per lamb; with some rams producing lambs that finished several weeks earlier than others.

The full results, which report the data collected and analysed from rams with the fastest growth rates, best conformation and most valuable progeny, will be presented in an industry webinar on 19 May, which is free to attend and open to all

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
