  • The effect of varying levels of readily available carbohydrates on urea utilization

    Creator:
    Wright, Rodney Joseph
    Abstract:
    The object of this research was to study the effect of readily available carbohydrates (RAC) upon the utilization of urea in fattening rations and to determine the effect upon carcass characteristics that determine quality and yield grades. A 2 x 2 latin square designed feedlot trial comparing urea at 0.5%...

  • Daily and alternate day supplementation of urea of biuret to ruminants consuming low-quality forage

    Creator:
    Currier, Thomas A.
    Abstract:
    Data is limited evaluating infrequent supplementation of urea or biuret to ruminants consuming low-quality forage (<6% crude protein). Therefore, a series of experiments were designed to compare the effects of daily (D) and alternate day (2D) supplementation of two non-protein nitrogen (NPN) sources (urea or biuret) to ruminants consuming low-quality...

  • Utilization of non protein nitrogen by rabbits

    Creator:
    Mathius, I-Wayan
    Abstract:
    Several studies have been conducted to examine the utilization of non-protein nitrogen by the New Zealand White rabbit. Soybean meal (SBM) or urea added to a low protein (13% CP) diet and a positive control diet were fed to does and their offspring during a nine month experiment. Urea and...

  • The effect of precipitation variation and fertilization level on the nutritive value of wheat residue

    Creator:
    Carey, Anne C.
    Abstract:
    Five simulated precipitation patterns characteristic of the Columbia Basin and Plateau region and six fertilization rates were evaluated for their effect on percent crude protein, percent in vitro dry matter digestibility, fiber content, and yield of wheat aftermath on a commercial farm in north central Oregon. The higher moisture regimes...
