    Abstract:
    The study involved three separate research efforts in which 10 Holstein calves and 85 purebred Hampshire and Suffolk ewe and ram lambs were employed. The objectives of the experiments were to characterize appetite, describe its inheritance and evaluate its associations with animal performance. In the calf experiment, appetite was determined...

  • Analysis of two alternative management systems for the production of fall born beef calves in western Oregon

    Creator:
    Rosecrans, John Gerald
    Abstract:
    Two management systems were evaluated in terms of the effects on calf growth, on calf weight produced per cow per year, and on reproductive performance of fall calving cows. The alternative management systems tested were twin foster calf production and, delayed weaning, production of single suckled calves weaned at the...

  • 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...
