In 2008, a consortium led by the Agricultural Research Service (ARS) and the National Institute for Food and Agriculture (NIFA) published the “Blueprint for USDA Efforts in Agricultural Animal Genomics 2008–2017,” which served as a guiding document for research and funding in animal genomics. In the decade that followed, many of the goals set forth in the blueprint were accomplished. However, several other goals require further research. In addition, new topics not covered in the original blueprint, which are the result of emerging technologies, require exploration. To develop a new, updated blueprint, ARS and NIFA, along with scientists in the …

The Role Of Direct-Fed Microbials In Conventional Livestock Production, Joe O. Buntyn, Ty Schmidt, David J. Nisbet, Todd R. Callaway Jan 2016

The Role Of Direct-Fed Microbials In Conventional Livestock Production, Joe O. Buntyn, Ty Schmidt, David J. Nisbet, Todd R. Callaway

Department of Animal Science: Faculty Publications

Supplementation of direct-fed microbials (DFM) as a means to improve the health and performance of livestock has generated significant interest over the past 15+ years. A driving force for this increased interest in DFM is to reduce or eliminate the use of low-dose antibiotics in livestock production. This increased attention toward DFM supplementation has generated an extensive body of research. This effort has resulted in conflicting reports. Although there has been considerable variation in the design of these studies, one of the main causes for this lack of consistency may be attributed to the variation in the experimental immune challenge …

Determination Of Yolk Contamination In Liquid Egg White Using Raman Spectroscopy, K. Cluff, G. Konda Naganathan, D. Jonnalagada, I. Mortensen, R. Wehling, Jeyamkondan Subbiah

Department of Animal Science: Faculty Publications

Purified egg white is an important ingredient in a number of baked and confectionary foods because of its foaming properties. However, yolk contamination in amounts as low as 0.01% can impede the foaming ability of egg white. In this study, we used Raman spectroscopy to evaluate the hypothesis that yolk contamination in egg white could be detected based on its molecular optical properties. Yolk contaminated egg white samples (n = 115) with contamination levels ranging from 0% to 0.25% (on weight basis) were prepared. The samples were excited with a 785 nm laser and Raman spectra from 250 to 3,200 …

New Distributional Records Of The Ohio Shrimp, Macrobrachium Ohione Smith (Decapoda: Palaemonidae) In Arkansas, H. W. Robison, L. Lewis, C. Cox, G. Spooner, R. Adams, C. T. Mcallister

Journal of the Arkansas Academy of Science

The Ohio shrimp (Macrobrachium ohione) is a migratory (amphidromous) river shrimp that occurs in some Arkansas rivers. It is known from the Upper Missouri River from its mouth downstream to the Gulf of Mexico, but shrimp abundance has declined, particularly upstream of Louisiana. Ohio Shrimp has also been collected in the lower reach of the Missouri River not far from the confluence of the Mississippi River in St. Louis County. Dams and alterations in channel flow are hypothesized to have impacted upriver migrations of shrimp. Current range, abundance, and life history of Ohio shrimp is relatively unknown in the Mississippi …

Food Habits Of Green Tree Frogs (Hyla Cinerea) From Arkansas, C. S. Thigpen, H. Dodson, S. E. Trauth Jan 2016

Food Habits Of Green Tree Frogs (Hyla Cinerea) From Arkansas, C. S. Thigpen, H. Dodson, S. E. Trauth

Journal of the Arkansas Academy of Science

We analyzed stomach contents of 120 Green Tree Frogs, Hyla cinerea, collected between May 1956 and October 2014 in Arkansas. Beetles and arachnids were the predominant prey item; the next most abundant groups were Diptera and Hemiptera. Vegetable matter was also found in several frogs. All identifiable vegetable matter was determined to be of the genus Persicaria, colloquially known as smartweed. Our data suggests that Green Tree Frogs in Arkansas predominantly feed on beetles and arachnids, but occasionally ingest plant matter when actively foraging.

Exploring Pharmacological And Behavioral Mechanisms Involved In Alcohol Dependence During Adolescence, Rabha Mousa Younis

Theses and Dissertations

Alcoholism is a serious illness that is marked by uncontrollable drinking and physical dependence to alcohol. Long-term alcoholism has been linked to many health concerns such as cirrhosis of the liver and cardiovascular disease. Alcohol is one of the most commonly used drugs among adolescent populations. Given that adolescence is a unique developmental stage during which alcohol has long-term effects on future drug-taking behavior; it is essential to understand how early exposure to alcohol during adolescence may affect the abuse liability of the drug later in life. Indeed, most alcohol users start during adolescence suggesting that exposure to alcohol during …

Evaluation Of Bison (Bison Bison) Ecology At The Olson’S Bison Conservation Ranches, Pine River Ranch, Manitoba, Canada, Joshua L. Leonard Jan 2016

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 Jan 2016

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 Jan 2016

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 …

Three Overlooked Issues: Water Quality, Forage Quality, And Forage Blends Impacting The Feed Efficiency Of Dairy Cows, Ishwary Prasad Acharya Jan 2016

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 Jan 2016

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 …

Evaluation Of The Hypothalamic Kisspeptin System Throughout The Estrous Cycle And During The Attainment Of Puberty In Gilts, Eric Steven Jolitz Jan 2016

Evaluation Of The Hypothalamic Kisspeptin System Throughout The Estrous Cycle And During The Attainment Of Puberty In Gilts, Eric Steven Jolitz

Electronic Theses and Dissertations

Kisspeptin has been demonstrated to affect reproductive cyclicity and the attainment of puberty in multiple species, presumably through its actions on GnRH and LH, as demonstrated in other species. Kisspeptin administration causes increased plasma concentrations of LH in pigs, sheep, and rats. Two experiments were conducted to evaluate 1) the hypothalamic kisspeptin system throughout various days of the estrous cycle and 2) the hypothalamic kisspeptin system during the peripubertal period in gilts. In experiment 1, 40 crossbred gilts (191 d, 121 kg) were administered an intramuscular injection of PG600. Twelve days after the administration of PG600, gilts were fed 15 …

Immune And Endocrine Modulations Associated With Enhanced Plant-Based Protein Diets Within Freshwater Fish Species, Timothy J. Bruce Jan 2016

Immune And Endocrine Modulations Associated With Enhanced Plant-Based Protein Diets Within Freshwater Fish Species, Timothy J. Bruce

Electronic Theses and Dissertations

The incorporation of bioprocessed soybean meals (BSBMs) as a protein replacement for marine-derived fish meal (MDFM) has gained momentum with the potential for aquafeed cost reduction, improved growth performance, and reducing exploitation on wild fish stocks. Further, potential health benefits and optimized production performance resulting from bioprocessed feed ingredients have led to research on the nutraceutical benefits of plant-based ingredients. A novel proprietary MBBM has been developed using a microbial conversion of carbohydrates into digestible protein and additional cellular components that have immunogenic potential. A series of five finfish feeding trials were conducted to investigate immunomodulation induced by the BSBM …

Raptors In Temperate Grasslands: Ecology Of Ferruginous Hawk, Golden Eagle, And Northern Harrier In The Northern Great Plains, Shubham Datta Jan 2016

Raptors In Temperate Grasslands: Ecology Of Ferruginous Hawk, Golden Eagle, And Northern Harrier In The Northern Great Plains, Shubham Datta

Electronic Theses and Dissertations

Ferruginous hawks (Buteo regalis) are a grassland and shrubland obligate nesting raptor and prefer lightly grazed pasture or idle areas for nesting. Their population reportedly declines in number if more than 30% of an area is cultivated and they rarely nest in areas dominated by croplands. Golden eagles (Aquila chrysaetos) are long-lived raptors with high nest-site fidelity and relatively low reproductive success. Population trends of golden eagles in western United States are unclear although long-term monitoring of populations shows declines in occupancy and breeding performance. Northern harriers (Circus cyaneus) prefer relatively open grasslands and …

Linking Vital Rates Of Landbirds On A Tropical Island To Rainfall And Vegetation Greenness, James F. Saracco, Paul Radley, Peter Pyle, Erin Rowan, Ron Taylor, Lauren Helton Jan 2016

Linking Vital Rates Of Landbirds On A Tropical Island To Rainfall And Vegetation Greenness, James F. Saracco, Paul Radley, Peter Pyle, Erin Rowan, Ron Taylor, Lauren Helton

Research outputs 2014 to 2021

Remote tropical oceanic islands are of high conservation priority, and they are exemplified by range-restricted species with small global populations. Spatial and temporal patterns in rainfall and plant productivity may be important in driving dynamics of these species. Yet, little is known about environmental influences on population dynamics for most islands and species. Here we leveraged avian capture-recapture, rainfall, and remote-sensed habitat data (enhanced vegetation index [EVI]) to assess relationships between rainfall, vegetation greenness, and demographic rates (productivity, adult apparent survival) of three native bird species on Saipan, Northern Mariana Islands: rufous fantail (Rhipidura rufifrons), bridled white-eye (Zosterops conspicillatus), and …

Assessment Of The Efficacy Of The Hose-Bridge As A Road-Crossing Structure For Dekay's Brownsnake (Storeria Dekayi), Sarah Elizabeth Manka Jan 2016

Assessment Of The Efficacy Of The Hose-Bridge As A Road-Crossing Structure For Dekay's Brownsnake (Storeria Dekayi), Sarah Elizabeth Manka

Masters Theses

Various structures have been integrated into roadways to ensure the road does not impede wildlife movements between adjacent habitats. Where traffic volume is low, the costs of installing and maintaining such structures is typically prohibitive. I tested the efficacy of a hose-bridge deployed temporarily on a State Park road in Illinois that allowed the passage of cars over it and small wildlife species to cross through it. I predicted that, during the 4.5 -week period of peak migratory movement, road-based mortality of Dekay's Brownsnakes (Storeria dekayi) would be less at the site having the hose-bridge, when compared to a similar …

Effects Of Habitat Alteration On Ecomorphology Of Fish Communities In A Restored Stream, Carl Anthony Favata Jan 2016

Effects Of Habitat Alteration On Ecomorphology Of Fish Communities In A Restored Stream, Carl Anthony Favata

Masters Theses

Decades of anthropogenic pressure have devastated lotic ecosystems across the riverscapes of North America, resulting in degradation of critical habitat and contributing to sharp declines in biotic integrity. In response, local stream restoration projects have increased in frequency. However, little effort has been allocated to monitoring and project success has been limited. In addition, restoration projects typically focus on ecological effects above the population-level, while relationships with physiological processes are seldom assessed. Lessons from the long-term restoration and ecological monitoring of Kickapoo Creek highlight some of the complex dynamics driving reach-scale restoration projects. Following instream restoration, I predicted that alterations …
