In most European dual purpose breeds beef merit is paid attention to b y selection among performance tested bulls where c o m paratively much weight is given to growth rate of performance tested bulls and relatively little weight to muscling and thus to carcass meat content. The genetic correlation between beef and dairy merit appears to be negative. This, in combination with large and effective selection pressure on milk leads to negating the effects of the little and relatively inccurate selection for beef merit at the best. Field progeny testing for beef merit can be economical and will permit to neutralize or even improve the beef merit of dual purpose cattle without much reduction in genetic p r o gress of dairy merit.
