Effect Of Grazing Pressure On Cattle Grazing Cool Season Annual Forages, Brooke Brunsvig

Electronic Theses and Dissertations

Ruminants can use plant fiber to produce food products that provide nourishment to humans. However, a precise understanding of specific plants selected by grazing ruminants remains elusive. Many long- and short-term factors impact cattle grazing behavior. Ultimately, grazing behavior can affect forage available for grazing, nutrient density of forage, dry matter intake, and animal performance. A myriad of grazing management strategies have been developed utilizing animal behavior to allow more efficient use of forage resources. Many management strategies based on manipulation of grazing behavior are simple and cost effective. Optimal performance of individual animals and amount of animal products produced …

The Cattle Dung Arthropod Community In Eastern South Dakota: Their Colonization, Impact On Degradation, And Response To Rangeland Management, Jacob Pecenka

Electronic Theses and Dissertations

Cattle grazing operations are an important industry throughout the world and a vital component of the economy of the Northern Great Plains. Rangeland management is important to ensure that cattle grazing remains not only profitable but also environmentally sustainable. Conventionally managed rangeland systems that practice continuous grazing and repeated applications of chemicals such as avermectins pose a risk to the continuing productivity of rangelands. These practices have ecological consequences, primarily to the arthropod community that inhabits cattle dung pats. This diverse community works together to recycle dung pats and make the nutrients in dung accessible to the surrounding plant community, …

A Comparison Of Land Use And Land Cover In Public Lands Of The Northwestern Great Plains And High Plains Ecoregions And The Implications For Grassland Birds, Dawn L. Siemonsma

Electronic Theses and Dissertations

Loss and degradation of grassland habitat are driving forces that contribute to widespread declines of grassland birds in the United States. Many studies have evaluated habitat needs for the conservation of grassland birds, but the relative contribution of public lands in representing and maintaining avian biodiversity remains poorly understood. Having a better understanding of the role that publicly managed grasslands play in the conservation of grassland bird habitat is important for assessing the value of the investment the American public makes in these lands. Therefore, I investigated spatial relations among variations in amounts and distributions of publicly owned and managed …

Effect Of Pre-Marketing Management Practices On Shrink Loss In Lambs, Ann Kolthoff

Electronic Theses and Dissertations

Two experiments were conducted to evaluate the effects of three common lamb pre-marketing management practices on live weight shrink loss. Additionally a producer survey was conducted to assess current marketing practices in the North Central region of the US. In these experiments, Exp. 1 (feeder lambs) and 2 (finished lambs), 60 commercial Polypay lambs (Exp. 1: 37.65 ± 0.30 kg of BW; Exp. 2: 52.56 ± 0.14 kg of BW) were allocated for each experiment to 3 treatment groups (n=20 lambs) in a 3 x 3 Latin square design. Treatments were the pre-marketing practices: original pen (ORG), transition pen (TRANS), …

Understanding The Effect Of Bvdv On Innate Immune Response Of Neutrophils, Neelu Singh Thakur

Electronic Theses and Dissertations

Bovine viral diarrhea virus (BVDV) is one of the highly prevalent and economically important diseases of cattle industry worldwide. The two major consequences of this disease are persistent infection and immunosuppression. Several studies have been done to determine the underline mechanisms of BVDV-induced immunosuppression targeting antigen presenting cells, adaptive immune system cells and cytokine gene expression. However, very little research has been done to determine the effect of BVDV on neutrophils. Neutrophils are one of the most abundant while blood cells (WBC) in the peripheral blood, which play a critical role in the innate as well as adaptive immune response. …

Development Of Highly Variable Microsatellite Markers For The Tetraploid Silene Stellata (Caryophyllaceae), Juannan Zhou, Michele R. Dudash, Charles B. Fenster, Elizabeth A. Zimmer

Natural Resource Management Faculty Publications

Premise of the study:We designed and tested microsatellite markers for the North American native species Silene stellata (Caryophyllaceae) to investigate its population genetic structure and identify selection on floral design through male reproductive success.

Methods and Results: A total of 153 candidate microsatellite loci were isolated based on next-generation sequencing. We identified 18 polymorphic microsatellite loci in three populations of S. stellata, with di- or trinucleotide repeats. Genotyping results showed the number of alleles per locus ranged from six to 45 and expected heterozygosity ranged from 0.511 to 0.951. Five of these loci were successfully amplified in S. …

Climate Change Impacts On Freshwater Wetland Hydrology And Vegetation Cover Cycling Along A Regional Aridity Gradient, Philip A. Fay, Glenn R. Guntenspergen, Jennifer H. Olker, W. Carter Johnson

Natural Resource Management Faculty Publications

Global mean temperature may increase up to 6°C by the end of this century and together with precipitation change may steepen regional aridity gradients. The hydrology, productivity, and ecosystem services from freshwater wetlands depend on their future water balance. We simulated the hydrology and vegetation dynamics of wetland complexes in the North American Prairie Pothole Region with the WETLANDSCAPE model. Simulations for 63 precipitation × temperature combinations spanning 6°C warming and −20% to +20% annual precipitation change at 19 locations along a mid-continental aridity gradient showed that aridity explained up to 99% of the variation in wetland stage and hydroperiod …

Mice With A Heterozygous Lrp6 Deletion Have Impaired Fracture Healing, Travis A. Burgers, Juan F. Vivanco, Juraj Zahatnansky, Andrew J. Vander Moren, James J. Mason, Bart O. Williams

Mechanical Engineering Faculty Publications

Bone fracture non-unions, the failure of a fracture to heal, occur in 10%–20% of fractures and are a costly and debilitating clinical problem. The Wnt/β-catenin pathway is critical in bone development and fracture healing. Polymorphisms of linking low-density lipoprotein receptor-related protein 6 (LRP6), a Wnt-binding receptor, have been associated with decreased bone mineral density and fragility fractures, although this remains controversial. Mice with a homozygous deletion of Lrp6 have severe skeletal abnormalities and are not viable, whereas mice with a heterozygous deletion have a combinatory effect with Lrp5 to decrease bone mineral density. As fracture healing closely models embryonic skeletal …

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 …

Determination Of Dimethyl Trisulfide In Rabbit Blood Using Stir Bar Sorptive Extraction Gas Chromatography-Mass Spectrometry, Erica Mananadhar, Nujud Maslamani, Ilona Petrikovics, Gary A. Rockwood, Brian A. Logue

Chemistry and Biochemistry Faculty Publications

Cyanide poisoning by accidental or intentional exposure poses a severe health risk. The current Food and Drug Administration approved antidotes for cyanide poisoning can be effective, but each suffers from specific major limitations concerning large effective dosage, delayed onset of action, or dependence on enzymes generally confined to specific organs. Dimethyl trisulfide (DMTS), a sulfur donor that detoxifies cyanide by converting it into thiocyanate (a relatively nontoxic cyanide metabolite), is a promising next generation cyanide antidote. Although a validated analytical method to analyze DMTS from any matrix is not currently available, one will be vital for the approval of DMTS …

Health and Nutritional Sciences Faculty Publications

Dietary modulation of the gut microbiota impacts human health. Here we investigated the hitherto unknown effects of resistant starch type 4 (RS4) enriched diet on gut microbiota composition and short-chain fatty acid (SCFA) concentrations in parallel with host immunometabolic functions in twenty individuals with signs of metabolic syndrome (MetS). Cholesterols, fasting glucose, glycosylated haemoglobin, and proinflammatory markers in the blood as well as waist circumference and % body fat were lower post intervention in the RS4 group compared with the control group. 16S-rRNA gene sequencing revealed a differential abundance of 71 bacterial operational taxonomic units, including the enrichment of three …
