  • Computer simulation of beef cattle production systems in the Llanos of Columbia

    Creator:
    Levine, Joel Martin
    Abstract:
    A simulation model capable of execution on a programmable calculator was developed to study voluntary intake, liveweight change, and fertility of grade Zebu cows in the Llanos of Colombia. Organic nitrogen in the diet and meta bolic weight were used to predict intake; age, liveweight, and energy concentration were the...

  • 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...
