Double Muscling 

THE EFFECT ON PRODUCTION EFFICIENCY AND MEAT QUALITY BY THE DOUBLE MUSCLING GENE IN CATTLE
(January 2003 - July 2006)

Aim

The aim of this project was to develop a better understanding of the effects of the double muscling gene on production, carcase and meat quality issues.

Why Is It Important

Some breeds of cattle are double muscled which is usually caused by the myostatin gene being deleted or non-functional.  These double muscled cattle are associated with some commercially attractive traits such as improved carcase conformation and feed conversion efficiencies, but they are also associated with an increased incidence of calving difficulty.

The information obtained in this trial allowed the economic, welfare and environmental impacts of the deleted form of the myostatin gene to be assessed, and provide producers with information on which to base breeding decisions.

South Devon and Angus cattle were used for the study.

Samples from cattle allowed the genotyping of parents and off-spring for double muscle status.  Off-spring destined for slaughter had records of the carcase quality made.

Who Will Do The Work?

The research was undertaken by the Roslin Institute, University of Bristol, MLC, Aberdeen Angus Cattle Society, South Devon Herd Book Society, and West Country Beef.

Project jointly funded by HCC, EBLEX, QMS and DEFRA.
