Taking Beef Cattle Breeding Into The 21st Century
Efficiency of beef production will be the major concern of beef breeders well into the twentyfirst
century. The competition from other protein sources will provide the incentive for the
beef industry to incorporate current breeding technology and the new emerging
biotechnologies into commercial production systems. Considerable effort by the scientific
community and expense to the industry will be encountered to make beef a competitive protein
source. A number of technologies are developing to enhance beef production efficiency.

Multibreed Genetic Evaluations Of Beef Cattle
Genetic evaluation for multibreed populations has received increased attention in the last
decade. Here we discuss modeling considerations for analysis of multibreed field data, review
strategies for analysis present in the literature, and discuss our experiences generating EPDs
for crossbred animals in the U. S. and Canadian Simmental genetic evaluation program.
