This study simulated total life-cycle expenses and income under value-based marketing to arrive at predicted net returns for crossbreeding systems. The simulation used a deterministic model of totally contained beef breeding systems and evaluated 14 breeds and their crosses from biological data collected at the U.S. Meat Animal Research Center in Nebraska. Comparing beef cattle crossbreeding systems under value-based marketing will aid us in understanding the interactions of the total system. Besides value of carcasses, feed requirements, level of milk production and other characteristics are important in determining net returns.
