Development And Application Of A Fish-Based Index Of Biotic Integrity For Lakes In Eastern South Dakota, Daniel T. Nelson
Development And Application Of A Fish-Based Index Of Biotic Integrity For Lakes In Eastern South Dakota, Daniel T. Nelson
Electronic Theses and Dissertations
The Index of Biotic Integrity (IBI) was developed to summarize the impact of watershed and water quality degradation to biotic communities and help to provide a more complete picture of water quality changes that are not captured in traditional physical and chemical measurements. In 2014, nearly 15% of South Dakota lakes did not meet their designated beneficial uses based on water quality measures but the impacts to the fish communities are unknown. The goal of this study was to develop a fish-based IBI for eastern South Dakota lakes by addressing three specific objectives:
1) Determine whether an IBI could be …
Using Rna Seq To Define Genes And Pathways Affecting Salmonella Vaccine Response In Beef Cattle, Sara Awrahman
Using Rna Seq To Define Genes And Pathways Affecting Salmonella Vaccine Response In Beef Cattle, Sara Awrahman
Electronic Theses and Dissertations
A Salmonella siderophore receptor and porin (SRP) proteins vaccine is an intervention strategy to control Salmonella burden in cattle. The vaccine works by stimulating immunity to produce antibodies against bacterial SRPs as siderophore molecules play a major role in transporting iron to bacteria. Blocking iron uptake system by antibodies causes death of bacterial cells. The vaccine can also be useful to protect humans against salmonellosis, which causes high rates of illness and death annually, by reducing shedding of Salmonella in the feces of cattle. Though other researchers have evaluated efficacy and immune response of this Salmonella SRP vaccine, genes …

Electronic Theses and Dissertations
Weaning is a stressful time in a piglet’s life that can have negative impacts on performance and health if not managed properly. The objective of this research was to evaluate the effects of a bioprocessed SBM alone or in combination with spray-dried plasma (SDP) or fishmeal (FM) on immune response at weaning with no imminent disease threat and during a porcine reproductive and respiratory virus (PRRSV) challenge. In the first trial, 239 pigs (initial BW 6.56 ± 0.87 kg, 21 d of age) were used in a 35-d study and allotted to one of 4 dietary treatments (10 pens/trt) according …
Growth Potential And Genetic Diversity Of Yellow Perch In South Dakota, Alex J. Rosburg
Growth Potential And Genetic Diversity Of Yellow Perch In South Dakota, Alex J. Rosburg
Electronic Theses and Dissertations
Yellow Perch Perca flavescens represent a valued sport fish throughout their range and are an important prey species for piscivorous fishes. In South Dakota, two distinct population types of Yellow Perch have been characterized that differ in growth, survival, and recruitment patterns. Fast growth populations exhibit high growth rates, high mortality, low population density, and inconsistent recruitment. In contrast, slow growth populations are characterized by reduced growth rates, low mortality, high population density, and relatively consistent recruitment. The role of genetics in contributing to these population characteristics is currently unknown. To address these questions, I used high-throughput restriction-site associated DNA …
Effects Of Maternal Plane Of Nutrition On Early Embryo Development And Offspring Performance, Erin E. Beck
Effects Of Maternal Plane Of Nutrition On Early Embryo Development And Offspring Performance, Erin E. Beck
Electronic Theses and Dissertations
Nutritional changes immediately after insemination can result in increased embryonic mortality, but the mechanisms that cause this increased mortality and the impact on the embryos that survive are not known. Therefore, two experiments were conducted to evaluate the impact of a nutritional change immediately following AI on calf performance, global DNA methylation, estrus expression and interval to estrus in heifers, peripheral metabolites, uterine luminal fluid metabolites, and day 6 embryo quality. In the first study (chapter 2) Angus-cross heifers (n = 142) were allotted into two developmental treatments: drylot or range. All heifers were fixed-time inseminated to a single sire …

Consequences Of Hatch Phenology On Stages Of Fish Recruitment, David M. Bogner, Mark A. Kaemingk, Melissa R. Wuellner
Consequences Of Hatch Phenology On Stages Of Fish Recruitment, David M. Bogner, Mark A. Kaemingk, Melissa R. Wuellner
Natural Resource Management Faculty Publications
Little is known about how hatch phenology (e.g., the start, peak, and duration of hatching) could influence subsequent recruitment of freshwater fishes into a population. We used two commonly sympatric fish species that exhibit different hatching phenologies to examine recruitment across multiple life stages. Nine yellow perch (Perca flavescens) and bluegill (Lepomis macrochirus) annual cohorts were sampled from 2004 through 2013 across larval, age-0, age-1, and age-2 life stages in a Nebraska (U.S.A.) Sandhill lake. Yellow perch hatched earlier in the season and displayed a more truncated hatch duration compared to bluegill. The timing of hatch influenced recruitment dynamics for …

The geography of the Black Hills region of South Dakota and Wyoming may limit connectivity for many species. For species with large energetic demands and large home ranges or species at low densities this can create viability concerns. Carnivores in this region, such as cougars (Puma concolor), have the additive effect of natural and human-induced mortality; this may act to decrease long-term viability. In this study we set out to explore genetic diversity among cougar populations in the Black Hills and surrounding areas. Specifically, our objectives were to first compare genetic variation and effective number of breeders of …

Evaluation Of Bobcat (Lynx Rufus) Survival, Harvest, And Population Size In The West-Central Region Of South Dakota, Brandon M. Tycz
Evaluation Of Bobcat (Lynx Rufus) Survival, Harvest, And Population Size In The West-Central Region Of South Dakota, Brandon M. Tycz
Electronic Theses and Dissertations
Recent concern regarding bobcat (Lynx rufus) population status has prompted researchers and managers to gather additional information about bobcats in South Dakota. From 2012–2015, we assessed population dynamics of bobcats occupying the west-central region of South Dakota. Our objectives were to: 1) estimate annual survival rates; 2) determine cause-specific mortality; 3) estimate a population size for the western prairie region of South Dakota; 4) estimate home range size of individually marked bobcats; 5) evaluate reproductive status; and 6) build a population model. We captured and radio-collared 51 (24 male, 27 female) bobcats with VHF collars. Annual survival was 65.1% (95% …

Evaluation Of Bison (Bison Bison) Ecology At The Olson’S Bison Conservation Ranches, Pine River Ranch, Manitoba, Canada, Joshua L. Leonard
Electronic Theses and Dissertations
Bison (Bison bison), the largest mammalian species in North America, historically numbering in the tens of millions (Roe 1970, McHugh 1972, Dary 1989, Shaw 1995), was nearly extirpated at the turn of the 19th century (Knapp et al. 1999; Gates et al. 2010). At the time, estimates of less than 1,000 bison remaining in North America are widely accepted (Hornaday 1889; Seton 1927; Gates et al. 2010). The decline of bison includes factors such as disease (Flores 1991; Isenberg 2000), sport hunting (Danz 1997; Dary 1989; Hewitt 1919; Isenberg 2000; McHugh 1972), and unofficially funded commercial hunting by the U.S. …
Effect Of Oil And Natural Gas Development On Survival And Health Of White-Tailed Deer In The Western Dakotas, Katherine L. Moratz
Effect Of Oil And Natural Gas Development On Survival And Health Of White-Tailed Deer In The Western Dakotas, Katherine L. Moratz
Electronic Theses and Dissertations
Oil and gas development in North Dakota has resulted in the need for information regarding how increased activity has affected white-tailed deer (Odocoileus virginianus) populations. We evaluated white-tailed deer ecology in response to energy development and hypothesized that oil and gas development would negatively affect adult and neonate white-tailed deer due to increased vehicle traffic and human-related effects. We captured and radio-collared adult female and neonate white-tailed deer across three study areas: Dunn County, North Dakota, an area influenced by energy development, and Grant County, North Dakota, and Perkins County, South Dakota, areas not impacted by energy development at this …
The Effect Of Copper And Zinc Source On Pre-Weaning Performance Of Cows, Health And Performance Of Suckling Calves, And Post-Weaning Feedlot Performance, Carcass Composition, And Meat Quality Of Calves, Jesse Fulton
Electronic Theses and Dissertations
During gestation an elevated level of nutrient intake is required by the cow in order to meet the requirements of the maturing fetus and if these requirements are not met, changes in fetal development can occur. However, little is understood about the effects of gestational manipulation of specific nutrients, such as minerals, on progeny growth, performance and carcass traits. Previous research supports the hypothesis that minerals provided in an organic form should be more soluble and readily available to the body for absorption. Therefore the objectives of this study were to determine if source of gestational and post-natal Cu and …

Manufacture, Concentration, And Functionality Of Micellar Casein Concentrate, Dustin Grossbier
Electronic Theses and Dissertations
This research has been structured into 3 major parts. The first part evaluates a centrifugal evaporator to concentrate micellar casein concentrate (MCC). The second part evaluates a wiped film evaporator (WFE) to concentrate MCC. The third part evaluates heat stability of the high concentration MCC produced by WFE. In part 1, the primary objective was to achieve >25% total solids (TS) without a loss of water removal rate associated with high solids materials. This is of importance, industrially, as this could reduce processing costs or eliminate drying all together. The major finding was that it did not offer any benefits …
Three Overlooked Issues: Water Quality, Forage Quality, And Forage Blends Impacting The Feed Efficiency Of Dairy Cows, Ishwary Prasad Acharya
Three Overlooked Issues: Water Quality, Forage Quality, And Forage Blends Impacting The Feed Efficiency Of Dairy Cows, Ishwary Prasad Acharya
Electronic Theses and Dissertations
The overall objectives of the six studies were to increase the feed efficiency in lactating dairy cows. The first study evaluated the efficacy of different water sources and treatment systems on ruminal parameters using an in vitro gas production system. Outcomes of the study suggested that the source and nutrient quality of water can affect rate of ruminal fermentation. Thus, use of real farm water being offered to the cow to conduct in vitro gas production measurements may accurately predict the ruminal fermentation, digestibility and total gas production. The second study evaluated two recently developed leafy-floury corn silage hybrids against …
Survival, Abundance, And Relative Predation Of Wild Rainbow Trout In The Deerfield Reservoir System, South Dakota, Jeremy L. Kientz
Survival, Abundance, And Relative Predation Of Wild Rainbow Trout In The Deerfield Reservoir System, South Dakota, Jeremy L. Kientz
Electronic Theses and Dissertations
Rainbow Trout Oncorhynchus mykiss are routinely stocked in Black Hills streams and reservoirs to enhance angling opportunities for the public, however in most cases, hatchery-reared Rainbow Trout do not successfully recruit to establish natural populations. One exception is the Deerfield Reservoir system, where it is estimated that up to 25% of the Rainbow Trout population consists of naturally produced, wild Rainbow Trout. While recruitment of wild Rainbow Trout to the Deerfield Reservoir fishery does occur, annual stockings of 12,000 hatchery Rainbow Trout have continued. In recent years, adipose fin clips were used to identify hatchery Rainbow Trout stocked into Deerfield …
