Effects Of Supplementing Propionibacteria In Lactation Dairy Diets On Ruminal Fermentation In Continuous Cultures, Karmella Ann Dolecheck Nov 2011

Effects Of Supplementing Propionibacteria In Lactation Dairy Diets On Ruminal Fermentation In Continuous Cultures, Karmella Ann Dolecheck

Undergraduate Honors Capstone Projects

The aim of the present study was to assess characteristics of in vitro ruminal fermentation when mixed cultures were offered lactation dairy diets supplemented with the direct-fed microorganism, Propionibacterium P63 in continuous cultures. The design of the experiment was a 2 × 2 factorial with 4 replications. Diets based on corn silage and alfalfa hay as the forage sources were formulated; high forage (HF) or low forage (LF) diet with a forage-to-concentrate ratio of 60:40 or 40:60 (DM basis), respectively, was combined without or with P63 to form 4 treatments: HF without P63, HF with P63, LF without P63, and …


Application Of Habitat And Occupancy Modeling To A Wood Duck Next Box Program, Jason D. Carlisle May 2011

Application Of Habitat And Occupancy Modeling To A Wood Duck Next Box Program, Jason D. Carlisle

Undergraduate Honors Capstone Projects

Programs to augment wood duck (Aix sponsa) nesting habitat by providing artificial nest boxes are commonly implemented. In northern Utah, where such programs are relatively new, I proposed a method to identify sites suitable for deployment of next boxes through a combination of habitat and occupancy modeling using site-specific, biotic, and abiotic, data collected from 105 next boxes over one nesting season in Cache County, Utah. An inductive habitat model was first developed which identified possibly suitable habitat (8.74% of county) based on proximity to hydrologic features. Next, based on comparing competing single-species, single-season, occupancy models using a modified Akaike's …


The High Cost Of Cheap Coal; Why Can't We Move To Renewable Energy, Cameron Dale Bartlett May 2011

The High Cost Of Cheap Coal; Why Can't We Move To Renewable Energy, Cameron Dale Bartlett

Undergraduate Honors Capstone Projects

This article addresses the historic and current use of coal as the main source of electric power throughout the United States. Coal powered power plants remain an important part of the history and industrialization of the United States, even though there are many detrimental health and environmental impacts associated with its use. A slowly growing trend has been emerging with research on and use of renewable energy to replace fossil fuels, such as coal. Greater public awareness and involvement will help drive the slowly emerging use of renewable energy. This article looks at the current barriers that are prohibiting the …
