Efficiency in Cow-Calf Systems With Different Ages of Cow Culling

The bioeconomic efficiency of cow-calf systems was compared by a deterministic dynamic simulation. The simulation model considered stable cow-calf systems differentiated by the maximum age for culling cows, lifetime, culled at 4–13 years old. The necessary supply of metabolizable energy for the herd...
