The objective of this study was to identify the varying effects of altering the rumen fluid: substrate ratio on the outcomes of in vitro rumen fermentation. In vitro fermentation is a useful tool for evaluating the energy value of feedstuffs and the effect of feed additives on Volatile Fatty Acid...
Bovine respiratory disease complex (BRD) is an infection of both the upper and lower respiratory tract and includes components of rhinitis, otitis, tracheitis, and pneumonia. Bovine respiratory disease (BRD) is one of the most common causes of morbidity and mortality of calves in the United States and world-wide. Besides the...
The unfolding of human retinoid X receptor α in the presence of the denaturant guanidine HCl was studied using stopped-flow absorbance spectroscopy. The protein's four native cysteine residues were mutated to obtain four single-cysteine mutants, each with the other three cysteine residues mutated to alanine. The thiols of these hRXRα...
This study sought to examine food choice motives and influences among Oregon Latinos to gain a greater understanding of their dietary acculturation. Previous studies relying principally on quantitative methods to assess the relationship between acculturation and diet have reported inconsistent results, though a general decline in diet quality is reported...
Selenium (Se) is an essential micronutrient in cattle, and Se-deficiency can affect morbidity and mortality. Calves may have greater Se requirements during periods of stress, such as during the transitional period between weaning and movement to a feedlot. Previously, we showed that feeding Se-fertilized forage increases whole-blood (WB) Se concentrations...
A four months continuous feeding trial was conducted
to evaluate Canola meal as a single protein supplement in
complete dairy rations. Thirty high producing Holstein
cows in the second week of lactation were randomly alloted
in groups of ten to one of three isonitrogenous (15% CP)
and isocaloric (1.6 Mcal/kg...
This thesis contains three manuscripts addressing the application of stochastic processes to the analysis and solution of partial differential equations (PDEs) in mathematical physics.
In the first manuscript, one dimensional diffusion and Burgers equation are considered. The Fourier transform of the solution to each PDE is represented as the expected...
