The objectives of this study were to nutritionally evaluate various
feather and hair meals (FM, HM) as protein supplements for ruminants
and to study the in vitro/in vivo relationships of diets supplemented
with FM and HM.
In vitro (rumen and enzymes) studies, five in vivo digestion
trials and a feedlot...
This study was designed to determine the relative
palatability of four varieties of ryegrass (Gulf, Ninak,
Charleston and Billion) based on their relative consumption
by cattle and to further evaluate the relationships between
daily consumption and individual nutrient components of
the grasses. Feedlot trials, chemical analyses for volatile
and nonvolatile...
The objectives of this study were to evaluate the feeding value
and potential toxicity of single cell protein (SCP) when fed to
ruminants.
Three in vivo digestibility trials with lambs, one feedlot trial
with steers and one long term feeding trial of high levels of SCP with
sheep were conducted...
A previously developed physiologically based pharmacokinetic (PBPK) model for bisphenol A (BPA) in adult rhesus monkeys was modified to characterize the pharmacokinetics of BPA and its phase II conjugates in adult humans following oral ingestion. Coupled with in vitro studies on BPA metabolism in the liver and the small intestine,...
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds are well-recognized for their immunosuppressive activity, which is mediated through an intracellular receptor and transcription factor, aryl hydrocarbon receptor (AhR). Laboratory animals exposed to TCDD are less resistant to infection and have severely impaired humoral and cell-mediated immune responses. This dissertation addressed the hypothesis that...
