In the United States, the major dietary source of protein is poultry meat, particularly chicken. Phosphorus absorption in chickens is a critical problem in poultry production. It therefore is important to understand the cellular and molecular regulation of phosphorous absorption in intestine to increase efficiency of the process. This would provide the benefits of reducing feed costs and reducing phosphorous excretion, thereby contributing to the sustainability of agriculture in the United States. Therefore, the focus of this thesis is determining the effect of vitamin D metabolites involved in phosphate homeostasis using the chicken as a model.

There is currently much interest in increasing health benefits from consuming nutritious food, including beef. Plant secondary compounds (PSC) such as tannins or saponins in various forages have an influence on animal nutrition and health, depending on the type of PSC and the amount consumed. However, relatively little is known about effects of PSC on meat color, flavor, and nutritional value. Thus, additional information is needed to better understand and to develop new animal feeding regimes for optimum animal growth, meat flavor, and meat nutritional quality.

In the first study, grain- vs. pasture-fed beef rib steaks were evaluated. The objective …
