Fruit Forage Integrated Systems For Diversification And Other Ecosystem Services, S. Ahmad, N. H. Mir, S. S. Bhat

IGC Proceedings (1993-2023)

The interspaces (alleyways) in fruit orchards are generally not utilized for cultivation of perennial forage crops by a majority of farmers. These alleyways are often occupied by weeds or kept bare or clean with repeated tillage. The weeds may act as alternate/collateral hosts, thereby harboring pests and pathogens that may harm the fruit trees. In addition to this, the frequent tillage may subject the soil to erosion losses. Intercropping of perennial forage grasses and/or legumes with fruit crops is thus beneficial for not only providing high quality forage but also for providing various ecosystem services.Owing to an ever burgeoning population, …

History Of Endophytic Toxicosis And Novel Variety Solutions, J. H. Bouton

IGC Proceedings (1993-2023)

Associations of Epichloe endophytes with tall fescue [Lolium arundinaceum (Schreb). Darbush.] and perennial ryegrass (Lolium perenne L.) form the basis for the known science and ecology of mutualistic, fungal endophytes, and especially their impact on livestock. In the USA, millions of acres are endophyte infected today due mainly to planting ‘Kentucky 31’ to reduce soil erosion. Health problems emerged later among animals grazing the grass. These toxicity symptoms were listed under the general term ‘Fescue Toxicosis’. Research demonstrated that ergot alkaloids produced by the mutualism were mainly responsible. Developing endophyte-free versions of major varieties reduced host grass persistence …

Comparison Of Two Low-Input Cow/Calf Production Systems On Temperate Grassland, W. B. Bryan, Mata Padrino, E. Felton, E. C. Prigge, V. W. Temu, O. J. Gekara

IGC Proceedings (1993-2023)

Two systems of grass farming were compared in an eight-year experiment in West Virginia, USA. The grassland consisted primarily of cocksfoot (Dactylis glomerara L.), Kentucky bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb.), and red (Trifolium pretense L.) and white clover (T. repens L.). The objective was to compare two systems of beef cow calf production. The experiment was a randomized complete block with two replicated treatments. The grassland of treatment 1 (system 1) was overseeded with legumes, grazing started 1 wk earlier and continued 1 wk later than treatment 2 (system 2) and …

Grazing Cover Crops In The Eastern Us: Performance Of Sheep, Goats, And Cattle Grazing Brassica Cover Crops, K. Cassida

IGC Proceedings (1993-2023)

Grazing annual forage crops has attained new interest with the increase in use of cover crops. Grazing annual forages grown as cover crops not only allows livestock producers to extend the grazing season but also gives row crop growers a way to recoup the cost of planting cover crops through grazing leases. Species in the Brassicaceae family (turnip, rape, kale, radish, and hybrids) have wide adaptability across the eastern US, excellent forage yield potential, and extremely high nutritional value. Brassicas are sometimes described as “high-moisture concentrates.” Their low effective fiber content drives the common recommendation to grow them with annual …

Extended Season Grazing On Two Ranches At Opposite Ends Of The Americas, Brett Chedzoy

IGC Proceedings (1993-2023)

Dormant season feeding of stored forages accounts for the majority of beef cattle production expenses across the world (Geiser and Boetel 2017). Additionally, most beef cattle production and particularly cow-calf operations are relegated to less accessible and productive landscapes, which reduces access to and increases costs for stored feeds. A comparison of two cow-calf operations owned and operated by the same family in the Province of Cordoba, Argentina and State of New York, USA are offered as case studies of creative solutions to these challenges. In Argentina, appropriate stocking for year-long grazing is the key to surviving the winter dormant …

The Partial Replacement Of Perennial Ryegrass Silage With Ensiled Biorefined Perennial Ryegrass Press Cake, And Its Impact On Productivity Of Late Lactation Dairy Cows, H. Costigan, B. Lahart, M. Kennedy, T. Rumley, L. Shalloo

IGC Proceedings (1993-2023)

Although necessary to maintain milk production in late lactation when grass is scarce, dependency on imported concentrate has negative environmental credentials; diversifying native feeds i.e., perennial ryegrass, using biorefinery, to produce high quality by-products may be a solution (Sanders et al., 2020). To validate these suggestions, a study was undertaken on dairy cows during the winter period; 60% of a perennial ryegrass silage diet was replaced with perennial ryegrass (PRG) press cake in treatment cows (GSPC; n=20), while a perennial ryegrass silage diet was offered to control cows (GS; n=20). Cows substituted with press cake produced 9.1 and 10.5 % …

Isoflavones In Legumes As Functional Forages And Feeds In Ruminant Grazing Systems, B. E. Davis, Michael D. Flythe, T. A. Hamilton, D. G. Ely, L. H. Anderson, J. R. Weinert-Nelson

IGC Proceedings (1993-2023)

Legumes are often utilized in livestock grazing systems to improve diet quality, diversity, and consequently animal performance. In addition to their nutritional utility, legumes contain phytoestrogenic isoflavones that have selective antimicrobial activity in the rumen and once absorbed can cause arterial vasodilation. These added bioactive functions of isoflavones suggest that legumes could be strategically utilized in grazing systems as functional forages to improve ruminant performance and health. The objective of this presentation will be to discuss past and current research on the application of isoflavones via legumes as an antimicrobial for growth promotion and as a mitigation strategy for fescue …

Cool-Season Annual Legumes And Forbs For Grazing And Cover Crop Systems, S. L. Dillard

IGC Proceedings (1993-2023)

Annual forage legumes and non-leguminous forbs can be used to interseed into perennial forage grasses or as a short-term grazing option between row crop rotations. Diversification of cropping systems by increasing number or type of cover crops in crop rotation plays an important role in improving land-use efficiency and in promoting sustainable agriculture. Legumes and other broadleaf forages provide increased forage digestibility and crude protein as a result of their greater leaf-to-stem ratio. In the Southeast U.S, few novel cultivars have been released in the last 20 years, resulting in the reliance on only a few forage cultivars and species. …

Animal And Forage Performance Of Integrated Crop-Livestock Systems, S. L. Dillard

IGC Proceedings (1993-2023)

Grazing of cool-season cover crops has been shown to be a viable tool for extending the grazing season while mitigating environmental risks associated with row-crop farming systems. Grazing cover crops is not novel, but most recent information available on this practice focuses on soil health as opposed to forage production and animal performance. Research has shown that forage quality of cool-season annual cover crops is sufficient to maintain an average daily gain of at least 1 kg/d and as high as 1.5 kg/d. Forage species selection plays an important role in the success of an integrated crop-livestock system. Grasses typically …

Swath Grazing: Feeding “Hay” Without The Production Expenses, V. Baron, A. C. Dick, A. Omaha

IGC Proceedings (1993-2023)

Swath grazing is a practice for overwintering beef cows on small grain forage left in the field to graze through snow, but annual variation occurs. The objective is to review 18 years of research at Lacombe, Alberta (AB) to describe how production attributes are related to cost mitigation and cow performance. Five trials compared swath grazing management options to pen-fed controls to determine feasibility. Associated studies monitored forage quality, soil fertility requirements and planting date impacts on yield. Mean, standard deviation, coefficient of variation, maximum and minimum values (n=18) for forage yield, pasture days, carrying capacity and percent utilization were …

Preliminary Results: Complementary C4:C3 Grazing Systems, M. Berry, P. Keyser, S. Jagadamma, H. Nauman, K. Coffey, C. Nieman, P. Owens, A. Ashworth, E. Bisangwa

IGC Proceedings (1993-2023)

Native warm-season grasses (NWSG) can produce high quality forage and high rates of gain for beef cattle. However, little data is available on how NWSG affect the productivity of cow-calf operations on a farm scale. Therefore, we implemented an experiment at three sites, Booneville, AR, Linneus, MO and Louisville, TN, with cow-calf pairs (mature cows over ≥ 3 years old, spring calving). We evaluated two forage systems that mix either a drought or drought/flood tolerant native C₄ species [big bluestem (BB) blend or eastern gamagrass (EG)] with a cool-season perennial, tall fescue (TF), and compared them to the most …

Fodder Scenario And Hortipastoral Opportunities To Enhance Fodder Production In India, Nagaratna Biradar, C. Lakshmi Devi, Vinod Kumar, Narendra S. Kulkarni, G. K. Kumar Anil, S. S. Guledagudda, A. Bheemappa

IGC Proceedings (1993-2023)

Food grain production and livestock production are closely related in India as crop-residue forms the major source of fodder for livestock. It’s thus assumed that increase in food grain production has positive effect on availability of dry matter to the livestock. Using land use classification, crop production (2015 to 2020) and livestock census (2019) data, dry matter (DM) availability for livestock for 28 states of India was estimated. Hortipastoral opportunities by estimating area available under orchards in southern India were done to assess the possibility of introducing fodder crops in orchards. Some of the fodder crops were introduced in orchards …

Chemistry Faculty Research & Creative Works

This study focused on the development of high-resolution polymeric structures using polymer-induced self-assembly (PISA) printing with commercially available digital light-processing (DLP) printers. Significantly, soluble solids could be 3D-printed using this methodology with controllable aqueous dissolution rates. This was achieved using a highly branched macrochain transfer agent (macro-CTA) containing multiple covalently attached CTA groups. In this work, the use of acrylamide as the self-assembling monomer in isopropyl alcohol was explored with the addition of N-(butoxymethyl)acrylamide to modulate the aqueous dissolution kinetics. PISA-printed microneedles were observed to have feature sizes as small as 27 μm, which was close to the resolution limit …

Unmixing Detrital Zircon U-Pb Ages Reveals Tectonic And Climatic Depositional Influences On The Carboniferous Ansilta Formation, Calingasta-Uspallata Basin, Western Argentina, Joshua R. Malone, John Malone, John L. Isbell, David H. Malone, John P. Craddock

Faculty Publications-- Geography, Geology, and the Environment

The Late Paleozoic Ice Age (LPIA) was a principal control of sedimentation across Gondwana from the late Devonian through early Permian. We assess the hypothesis that glacial to interglacial transitions in western Argentina were the primary control influencing sediment routing patterns among the various Carboniferous-Permian basins in western Argentina. The Carboniferous Ansilta Formation consists of glaciomarine, nearshore, and fluvial systems deposited during the LPIA along the eastern margin of the Calingasta-Uspallata Basin in Argentina. The lower, glacially influenced succession of the Ansilta Formation records at least five glacial advances; the upper succession of consists of progradational shallow marine, deltaic, and …

Detection And Relative Quantitation Of Changes In Gene Expression Of Hippo Proteins In Doxorubicin-Exposed Human Cells By Rt-Qpcr, Lillian Fleisher, Tricia Domingo, Christopher So, Stephen Lee

Annual Research Symposium

The HIPPO signaling pathway plays a key role in cell proliferation and tumor suppression. It consists of serine/threonine kinase cascades, including MST1/2, LATS1/2, YAP, and TAZ. When the HIPPO pathway is activated, gene expression is altered. Dysfunction of the activity of this cascade may contribute to cancer development and chemoresistance. FAT4 is an intracellular protein that may regulate the HIPPO signaling. The purpose of this study is to determine the relative changes of mRNA of the HIPPO pathway members and FAT4 in doxorubicin-treated and vehicle-treated in vitro cell lines.

An Icosahedron For Two: A Many-Sided Look At Making A Duet, Colleen T. Wahl

LASER Journal

The space around our bodies is not empty or neutral. In fact, the space around our bodies is loaded with meaning and important. When we move through it, whether it be in our daily lives or a choreographer making specific choices in order to convey a message, we activate new understandings in our lives. As a dancer and choreographer, I created a duet from improvisational climbs on an icosahedron. This article discusses choreographing from the form icosahedron and connects Laban's theories of space harmony with the activation of meaning in my life.

Unimer Suppression Enables Supersaturated Homopolymer Swollen Micelles With Long-Term Stability After Glassy Entrapment, Eric R. Williams, Christian X. Ruff, Morgan Stefik

Faculty Publications

Micelle sizes are critical for a range of applications where the simple ability to adjust and lock in specific stable sizes has remained largely elusive. While micelle swelling agents are well-known, their dynamic re-equilibration in solution implies limited stability. Here, a non-equilibrium processing sequence is studied where supersaturated homopolymer swelling is combined with glassy-core (“persistent”) micelles. This path-dependent process was found to sensitively depend on unimer concentration as revealed by DLS, SAXS, and TEM analysis. Here, lower-selectivity solvent combinations led to the formation of unimer-homopolymer aggregates and eventual precipitation, reminiscent of anomalous micellization. In contrast, higher-selectivity solvents enabled supersaturated homopolymer …

Determining The Surface PKA Of Perfluorooctanoic Acid, Lila J. Musegades, Owen P. Curtin, Jenée D. Cyran

Chemistry and Biochemistry Faculty Publications and Presentations

Perfluorooctanoic acid (PFOA) is an environmentally prevalent and persistent organic pollutant with toxic and bioaccumulative properties. Despite the known importance of perfluorinated pollutants in the global environment, molecular-level details of the physicochemical behavior of PFOA on aqueous interfaces remain poorly understood. Here, we utilized two surface-specific techniques, vibrational sum frequency generation spectroscopy (SFG) and surface tensiometry, to investigate the pH-induced structural changes of PFOA and octanoic acid (OA) and determined the apparent pK_a at the air–water surface. The SFG spectra and surface activity model were investigated over a wide range of pHs. With the surface tension measurements, the …

Howard, Yun Zhang, Bridget A. Tripp, Jennifer Clarke, Amy B. Howell, Joel H. Rubenstein, Julian A. Abrams, Maria Westerhoff, Laura A. Kresty

Department of Statistics: Faculty Publications

The gut and local esophageal microbiome progressively shift from healthy commensal bacteria to inflammation-linked pathogenic bacteria in patients with gastroesophageal reflux disease, Barrett’s esophagus, and esophageal adenocarcinoma (EAC). However, mechanisms by which microbial communities and metabolites contribute to reflux-driven EAC remain incompletely understood and challenging to target. Herein, we utilized a rat reflux-induced EAC model to investigate targeting the gut microbiome–esophageal metabolome axis with cranberry proanthocyanidins (C-PAC) to inhibit EAC progression. Sprague-Dawley rats, with or without reflux induction, received water or C-PAC ad libitum (700 μg/rat/day) for 25 or 40 weeks. C-PAC exerted prebiotic activity abrogating reflux-induced dysbiosis and mitigating …
