Summer Foraging Range And Diurnal Roost Selection Of Tri-Colored Bats, Perimyotis Subflavus., Dustin Bradley Thames
Summer Foraging Range And Diurnal Roost Selection Of Tri-Colored Bats, Perimyotis Subflavus., Dustin Bradley Thames
Masters Theses
Tri-colored bat populations are declining in eastern North America where the fungal pathogen Pseudogymnoascus destructans has been introduced. The pathogen causes disease and mortality in cave hibernating bats. Once considered a common species in Tennessee, tri-colored bats are now being considered for protection under the Endangered Species Act. There is a paucity of research examining the basic ecology of tri-colored bats. Research to fill these knowledge gaps is needed to inform conservation plans and to define critical habitat. The first objective of my research was to characterize the summer diurnal roosts of tri-colored bats and to examine roost selection at …
Predicting Voluntary Forage Intake Of Supplemented Beef Cattle, Connor Biehler
Predicting Voluntary Forage Intake Of Supplemented Beef Cattle, Connor Biehler
Masters Theses
A major priority of beef cattle production is to meet animal nutrient requirements in order to achieve a desired level of productivity. Accurately predicting voluntary forage intake (VFI) is necessary to accurately predict the total nutrient intake of grazing or forage-fed beef cattle that are also supplemented with other sources of nutrients. Therefore, the objectives of this experiment were to utilize data from published literature to 1) identify factors that explain variation in VFI, and 2) develop and validate one or more mathematical models that predict VFI or total nutrient intake of grazing or forage-fed and supplemented beef cattle. A …
Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch
Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch
Masters Theses
Despite the vast production markets for forage and organic products nationally, so far limited work has been done to develop organic forages specifically for Middle Tennessee or the mid-South in general. The present organic research field focuses on vegetable and grain production; however, forage production offers an easier transition for producers moving into certified organic agriculture. The present study seeks to evaluate several forage blends for optimizing forage production under low-input transitional organic conditions. Ideally a forage system could be tailored to the beef cattle operations of Middle Tennessee, the dominant forage consumption market in this region of the mid-South. …
Microbial And Metabolomic Biomarkers Of Feed Efficiency In Angus Cattle, Brooke Ashley Clemmons
Microbial And Metabolomic Biomarkers Of Feed Efficiency In Angus Cattle, Brooke Ashley Clemmons
Doctoral Dissertations
In Tennessee and the United States, cattle account for a significant proportion of the livestock agricultural sector. In the beef cattle industry, 40-70% of the total cost of production comes from feed costs, resulting in billions of dollars going towards feeding cattle. Thus, identifying methods for improving feed efficiency is imperative for reduced feed input costs and more effective use of environmental and economic resources. The rumen microbiome contributes a vast amount of nutrients for the host ruminant, including approximately 70% of energy precursors as well as vitamins, proteins, and other nutrients. These microbes produce metabolites that are then available …
Improving Body Composition In Broiler Chicks Through The Early Life Diet, Kamille Piacquadio
Improving Body Composition In Broiler Chicks Through The Early Life Diet, Kamille Piacquadio
Masters Theses
The poultry industry relies heavily on the efficient growth performance of broilers to provide quality breast meat at a low cost to meet consumer demand. However, high efficiency of broilers is also related to the occurrence and severity of skeletal muscle abnormalities like wooden breast. This study investigated the efficacy of incorporating long-chain omega-3 polyunsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), into the diets of hens and their offspring on altering the causative features of wooden breast. Early exposure to these fatty acids in broilers has shown to reduce adiposity, and may address excess adipogenesis seen in …
Effects Of A Moderate And Aggressive Implant Strategy On The Rumen Microbial Community And Metabolome In Steers, Madison Henniger
Effects Of A Moderate And Aggressive Implant Strategy On The Rumen Microbial Community And Metabolome In Steers, Madison Henniger
Masters Theses
The effects of growth-promoting implants have been well-defined for their ability to impact growth in beef cattle. Production-relevant microbiomes in the rumen have also been associated with growth traits. However, the role of implant strategies on the rumen microbiome is not understood. The objective was to determine if varying doses of implant hormones cause gain-associated ruminal microbial community shifts. To assess this, a completely randomized design was used and 336 fall-born steers between 450-470 days of age from the germplasm evaluation population at the US Meat Animal Research Center (Clay Center, NE) were divided into two treatment groups: 1) a …
