Mathematical modeling of selection and crossbreeding in beef cattle

Creator:: Clarke, Stephen Emil
Abstract:: A mathematical model was developed to simulate alternative selection and crossbreeding strategies for commercial beef production. Biological and economic constraints were selected to represent typical pasture production of calves in the Northwest. The crossbreeding study evaluated the relative economic efficiency of different 1) mating plans when sire breeds of several...
