Scientists secret of big beefy bullocks genes
US journal Genome Research reports that scientists have identified the gene which made a Belgian Blue bullock grow more muscle and provide more lean red meat.
The discovery could open the way for new methods of cattle breeding. However the calves may be to big too be born naturally.
A solution may be to manipulate the gene so the animals grow large and beefy only after they have been born.
