Biotic Integrity In The Northwestern Great Plains And Mechanisms Regulating Stream Condition In South Dakota, Chad Kaiser
Biotic Integrity In The Northwestern Great Plains And Mechanisms Regulating Stream Condition In South Dakota, Chad Kaiser
Electronic Theses and Dissertations
Anthropogenic disturbance of streams can alter biotic integrity in various ways. Some degradation is easy to classify and monitor, others such as habitat impairment may be less easy to quantify. The Index of Biotic Integrity (IBI) is a unique method of assessing the aquatic health of an ecosystem. Beginning in 2010 the South Dakota Department of Environment and Natural Resources (SD DENR) began implementing biological monitoring on wadeable streams by developing an IBI for the Northern Glaciated Plains ecoregion in eastern SD (Krause et al. 2013). Prior to this survey the condition of the majority of SD’s streams was unknown. …
Heterogeneous Nitrogen Losses: Cost-Effectiveness Analysis Of Changes In Management Across South Dakota, Archibold Quaye
Heterogeneous Nitrogen Losses: Cost-Effectiveness Analysis Of Changes In Management Across South Dakota, Archibold Quaye
Electronic Theses and Dissertations
The loss of nitrogen fertilizer into the atmosphere and waterways is of increasing concern for citizens and policy makers. This is particularly relevant for hypoxia in rivers, lakes, and oceans, but also relevant for policy makers in reducing the increasing concentration of greenhouse gases (GHG) in the atmosphere. GHGs trap heat in the atmosphere and include: carbon dioxide, methane, nitrous oxide and fluorinated gases. Overall, the estimated contribution from the agricultural sector to GHG emissions was 9% in 2013 (EPA, 2013). Further, the addition of nitrogen to the soil through the use of synthetic fertilizers is a main contributor to …
Evaluation Of Supplementing Brewer's Yeast To Lactating Dairy Cows, Taylor Christine Aubrey
Evaluation Of Supplementing Brewer's Yeast To Lactating Dairy Cows, Taylor Christine Aubrey
Electronic Theses and Dissertations
Probiotics have been used as effective, natural feed additives in the dairy industry to improve animal health and performance. Yeast product supplementation can be beneficial in the diet of lactating dairy cows by increasing feed efficiency, alleviating disease, and improving production performance under heat stress. Objectives of this study were to evaluate supplementing a concentrated brewer’s yeast in the ration of a lactating dairy cow by assessing milk yield and composition, blood metabolites, rumen fermentation, and feed intake and efficiency. We hypothesized that diets containing a concentrated brewer’s yeast supplement would increase milk and component yields, benefit rumen fermentation, and …
The Influence Of Chromium Supplementation On The Insulin Pathway, Carcass Traits, And Meat Quality Of Feedlot Steers, Heather Rode
The Influence Of Chromium Supplementation On The Insulin Pathway, Carcass Traits, And Meat Quality Of Feedlot Steers, Heather Rode
Electronic Theses and Dissertations
Chromium supplementation (Cr) can increase efficiency of growth in livestock by amplifying insulin signaling. Previous research showed Cr increases nutrient utilization and changes in muscle growth and fat deposition. Therefore, the objective of this research was to determine how Cr affects carcass traits, meat quality, and the insulin pathway in feedlot steers. Calf-fed steers were allotted to 0 ppb (CON) or 400 ppb Cr propionate (Cr400) for 210d in experiment 1. Two longissimus muscle (LM) biopsies were collected to examine protein abundance and gene expression after adaptation to a terminal implant and after adaption to ractopamine hydrochloride (RAC). A follow …
Assessment Of Nutritional Counseling Frequency On Weight Status In Renal Transplant Recipients, Kelly Butler
Assessment Of Nutritional Counseling Frequency On Weight Status In Renal Transplant Recipients, Kelly Butler
Electronic Theses and Dissertations
Objective: The goal of this study was to determine if there is an association between educational interventions by a RD and weight in the twelve months’ post-transplantation. A secondary aim is to study trends in blood lipid profiles in participants and the number of times visited with a RD.
Methods: A retrospective study of electronic medical records from consenting, de-identified RTR at a Midwest transplant center were collected. Specific biological and anthropometric measures were analyzed.
Results: Patients that met with the out-patient dietitian more frequently (4 to 9 times) experienced less weight gain than patients that only saw the …
Effect Of Ultrasonication On Biofilm Forming Ability Of Common Dairy Sporeformers, Taghreed Almalki
Effect Of Ultrasonication On Biofilm Forming Ability Of Common Dairy Sporeformers, Taghreed Almalki
Electronic Theses and Dissertations
Sporeformers are common dairy contaminants, which are of a great concern to the dairy industry. Quality of dairy products is affected by these sporeformers such as Bacillus species, which are a significant cause of spoilage of dairy products. Thermal processes such as pasteurization have been used to inactivate pathogens, but some of the sporeformers and their endospores are resistant to such heat treatments. Beside thermal treatments, various new approaches are being developed to improve the quality of dairy products. Amongst these, ultrasonication is a promising non-thermal technique for the inactivation of thermoduric sporeformers and their endospores. Current study was carried …
