  • Senecio jacobaea : toxicity and effects on mineral metabolism in animals

    Creator:
    Swick, Robert Alphonso
    Abstract:
    Several experiments were conducted to examine the toxicity of Senecio jacobaea (SJ) in animals resistant to pyrrolizidine alkaloid (PA) intoxication and to determine the extent of alterations in mineral metabolism as a result of SJ intoxication. Inclusion of SJ into diets containing added copper (Cu) resulted in increased (P<.01) liver...

    Pote, Linda Marie Wayland.
    Abstract:
    A series of experiments were conducted to determine the utilization of fibrous feeds by the rabbit. A review of literature was performed to ascertain the results of similar studies. The first two experiments involved various levels of alfalfa substituted for corn or barley. Results indicated that a 50 percent alfalfa...

  • Dietary factors influencing the toxicity of tansy ragwort (Senecio jacobaea) in animals

    Creator:
    Swick, Robert Alphonso
    Abstract:
    Senecio jacobaea (tansy ragwort) is a poisonous plant responsible for livestock deaths in the Pacific Northwest. Horses and cattle are susceptible, while sheep are resistant to the toxic action of the pyrrolizidine alkaloids which the plant contains. Hepatic enzymes are responsible for the biotransformation of pyrrolizidine alkaloids into tissue damaging...

  • Mutagenic and toxicologic implications of pyrrolizidine (Senecio) alkaloids

    Creator:
    White, Randy Dee
    Abstract:
    The Salmonella/mammalian-microsome mutagenicity test was used to evaluate Senecio jacobaea (SJ) plant, Pyrrolizidine alkaloids (PA) and metabolites in goat milk, to evaluate response differences with microsomes from several animal species and to compare SJ plant responses to other plants. Bioassessment experiments were conducted to evaluate PA toxicity changes associated with...

    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...

    Abstract:
    Nine feeding trials and four laboratory scale experiments were conducted in this study. The study consisted of: (1) use of grass straw:corn juice (CJ) silages with fishmeal and/or alfalfa hay supplementation in beef heifers, sheep, pregnant dairy heifers, water buffaloes and Hereford cows; (2) use of cull onions:grass straw silages...
