  • Flow cytometric evaluation of spermatozoan nuclear chromatin structure and viability

    Creator:
    Ballachey, Brenda Elizabeth
    Abstract:
    I. Frozen bovine semen samples were measured by flow cytometry (FCM) to determine if FCM analyses could be useful for sperm quality evaluation and prediction of bull fertility. Fluorescent dyes utilized were acridine orange, to measure sperm nuclear chromatin heterogeneity by quantifying susceptibility of the chromatin to denaturation, and rhodamine...

  • 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...
