Using Abattoir Data to Create EBVs

New EBVs for Beef Cattle Click the link below to read the final project report for the EBVs from abattoir data project. The project combines real abattoir carcase data and information from other national databases, including BCMS, to create genetic evaluations for actual carcase weight, conformation, fat class and age at slaughter. EBVs have been produced for nearly 3 millio ...

Terminal Sheep Breeds Make Strong Genetic Gains

Substantial gains are being made in genetic progress for terminal sheep populations in the UK Genetic gain in recorded and unrecorded populations has increased dramatically since the initial sire reference scheme began in 1990, as demonstrated by the Terminal Sire Index (Figure 1) for Suffolk and Texel breeds. It is important to recognise that the rate of genetic gain is aroun ...

Beef Carcase Traits Project – The Breeds Involved

Beef producers in the UK aim to produce high quality meat as efficiently as possible but ultimately, payments for cattle relate to their carcase weight, conformation and fatness – with producers aiming for an R4L carcase or better on the EUROP grid. To provide commercial producers with better tools to aid bull selection, AHDB Beef & Lamb, AHDB Dairy and HCC funded a resear ...

A New Lamb Survival EBV in Progress

Signet and EGENES (SRUC) have been looking at creating a new postnatal lamb survival EBV to help breeders genetically improve young animal resilience and identify families with poor survival rates. The ability to enhance this trait could have a huge impact on animal welfare and flock profitability, especially in the current economic climate where every lamb counts. While it i ...

Guidelines for ultrasound scanning

Changes to the guidelines relating to the ultrasound scanning of sheep Samuel Boon, Signet Breeding Services and Janet Roden, Independent Geneticist – October 2016 The use of ultrasound scanning to measure muscle and fat depth in Signet recorded flocks has been one of the great success stories of the last 30 years. The scanning services provides proxy measures for body compos ...

Changes to the Scottish Blackface Breeding Evaluation produced for Signet Recorded Flocks

Samuel Boon, September 2016 Based on work completed by EGENES/SRUC and funded by AHDB Beef and Lamb & Quality Meat Scotland   Summary AHDB and QMS recently funded two enhancements to the Scottish Blackface Breeding Evaluation and these are incorporated in your latest results. Improvements have been made to the way EBVs are calculated, particularly traits like the Lit ...

Recording sire information on BCMS passports generates new breeding tools for carcase traits.

Kim Matthews and Samuel Boon Whilst improvements in carcase conformation and fat class have been observed over the last decade, at present only 55% of prime cattle slaughtered in Britain met the target of E, U or R for conformation and 1, 2, 3 or 4L for fat class. One means of improving carcase quality is to breed cattle with better carcase characteristics. Currently this i ...
