A Solution To Weed Control In Grassland Containing White Clover, E. Bardsley, T. Schulz, R. Bentley, V. Van Damme, D. Gurney, N. Blanchier, B. B. Sleugh Nov 2023

A Solution To Weed Control In Grassland Containing White Clover, E. Bardsley, T. Schulz, R. Bentley, V. Van Damme, D. Gurney, N. Blanchier, B. B. Sleugh

IGC Proceedings (1977-2023)

Productive grass with white clover can lead to advantages both in forage quantity and quality, economics and in meeting wider expectations detailed in recent EU and UK policy. The ability to achieve this agronomic success is currently difficult due to a lack of options for broad spectrum weed control that also allow establishment or preservation of a white clover population. The aim of this paper is to demonstrate that 3730XL, developed by Corteva Agriscience, is a solution to this critical success factor. Data is presented from 16 efficacy trials (10 from established grassland and 5 from newly sown) where white …

Climate Change And Legume Performance In Grassland Agroecosystems, Lynn E. Sollenberger, M. M. Kohmann Nov 2023

Climate Change And Legume Performance In Grassland Agroecosystems, Lynn E. Sollenberger, M. M. Kohmann

IGC Proceedings (1977-2023)

We reviewed the literature to assess the effect of climate change factors on forage legumes. Whether growing in monoculture or mixtures with grasses, exposing legumes to elevated CO2 (eCO2) generally leads to sustained increases in forage accumulation (FA) and N fixation, but elevated temperature (eT) in conjunction with eCO2 usually reduces magnitude of these responses. In legumes, nodules represent large C sinks, precluding photosynthetic acclimation to eCO2 observed in non-N fixing plants. Greater N fixation in legume-grass mixtures exposed to eCO2 is due to greater percentage of legume N derived from symbiotic fixation and …

Cattle Diet Composition Under A Short- Duration Grazing With And Without Deferment In Puna Rangelands, R. E. Tácuna, E. R. Flores

IGC Proceedings (1977-2023)

The treatments of rest and deferment periods have shown to be effective tools to improve range condition, but little is known about their effect on the diet of animals. The present research aimed to evaluate the effect of the deferment period when applied to a short-term grazing system. The experimental design was a completely random factorial where the treatments resulted from combination of two grazing management systems: short-duration with deferment period (WD) and no deferral period (ND) both evaluated for three years. Forage yield (4.9 vs. 4.5 Tm DM ha-1 year-1) like range condition (55.5 vs. 50.7%) …

Impact Of Dry Matter At Ensiling On Final Ph And Nutritive Value Of Mixed Cool-Season Haylage, Christopher D. Teutsch, A. E. Teutsch Nov 2023

Impact Of Dry Matter At Ensiling On Final Ph And Nutritive Value Of Mixed Cool-Season Haylage, Christopher D. Teutsch, A. E. Teutsch

IGC Proceedings (1977-2023)

Harvesting hay as baleage can allow for more timely harvest, especially in spring months when curing conditions are not ideal. Forage conserved as baleage undergoes anaerobic fermentation in which the sugars are converted to lactic acid, lowering final pH. To successfully conserve forage as dry hay, moisture concentrations must be less than 18%. In contrast, the ideal moisture concentration for baleage is between 55 and 65%. There are a number of producers harvesting and wrapping hay that is not quite “dry enough” to bale but is too dry to ensile. This produces a product commonly referred to by producers as …

Cool-Season Perennials And Stability In Year-Round Forage Production Systems, C. D. Teutsch Nov 2023

Cool-Season Perennials And Stability In Year-Round Forage Production Systems, C. D. Teutsch

IGC Proceedings (1977-2023)

Changes in long-term climate normals have resulted in warmer and wetter summers and milder winters in the humid eastern United States. This will likely impact regional forage species adaptation in the long-term and varietal adaptation in the short term. Variety evaluation has been occurring at the University of Kentucky for almost 100 years. There are several considerations for selecting forage species and varieties including regional and local adaptation, productivity, distribution of growth, palatability, nutritive value, anti-quality factors, tolerance to stress, and persistence. Two of the most important criteria are long-term productivity and persistence under grazing, both of which are currently …

Impact Of Fertilizer Type, Seeding Coating, And Duration Of Exposure On The Germination Of Red Clover Seed, C. D. Teutsch, Edwin L. Ritchey

IGC Proceedings (1977-2023)

Legumes are important components in grassland ecosystems. Red clover is one the most used legumes in the transition zones states like Kentucky. To maintain legumes in grass pastures, improved red clover varieties are often overseeded in the late-winter or early-spring. In many cases seed is mixed with fertilizer and top-dressed onto pastures. Little data are available on the impact of fertilizer type or duration of exposure on the germination of raw and coated red clover seed. The objective of this study was to evaluate the impact of two fertilizer types, muriate of potash and a blended fertilizer (urea, diammonium phosphate, …

Effect Of The Hydrological Keyline Design On The Growth And Quality Of The Naturalized Grassland In The Dry Central Zone Of Chile, P. Toro-Mujica Nov 2023

Effect Of The Hydrological Keyline Design On The Growth And Quality Of The Naturalized Grassland In The Dry Central Zone Of Chile, P. Toro-Mujica

IGC Proceedings (1977-2023)

The effect of climate change in the central, semi-arid zone of Chile has altered precipitation patterns, shortening the growing season of the naturalized annual grasslands and reducing forage yields. Water harvesting techniques such as the hydrological keyline design, may improve the distribution of precipitation, reduce erosion, and enhance soil water harvesting. It may therefore reduce the impact of climate change in rainfed areas. A trial was implemented to evaluate the effect of the keyline water harvesting practice on soil variables, and pasture production and quality in three farms of the semi-arid O'Higgins region. Rains began in April and amounted to …

Bovine respiratory disease (BRD) is a leading cause of disease in feedlot and stocker calves with Mannheimia haemolytica (MH) as one of the most common etiologies. One of the most effective means of controlling BRD is through metaphylaxis, which involves administering antimicrobials to all animals at high risk of developing BRD. However, increasing prevalence of multidrug resistant (MDR) MH may reduce efficacy of metaphylaxis due to decreased susceptibility to drugs used for metaphylaxis. Primarily, this study aimed to determine the effect of tulathromycin metaphylaxis and subsequent BRD treatment on antimicrobial resistance (AMR) in MH isolated from stocker calves. Secondary objectives …

Mechanisms, Evolution, And Rapid Diagnosis Of Carbapenem Resistance, Taalin Shale Hoj Nov 2023

Mechanisms, Evolution, And Rapid Diagnosis Of Carbapenem Resistance, Taalin Shale Hoj

Theses and Dissertations

An estimated 70% of bacterial infections in the United States are resistant to first-line antibiotics. Of these, among the most difficult to treat are highly resistant to carbapenems, an antibiotic class used as a last resort. Septicemia, particularly when caused by a carbapenem-resistant organism, is among the most challenging clinical scenarios to treat, with an overall mortality rate of carbapenem-resistant septicemias 63.8%. Encouragingly, if effective antimicrobial treatment begins within 1-3 hours of septic shock onset, patient survival rates are around 80%. The first section of this work describes a real-time PCR-based assay that when coupled with existing bacteria-blood separation technology, …

Elucidating The Architecture Of The Tclijn Complex That Converts Cysteine To Thiazoles In The Biosynthesis Of Micrococcin, Diana G. Calvopina Chavez

Theses and Dissertations

Thiopeptides are a family of antimicrobial peptides that are characterized for having sulfur-containing heterocycles, and for being highly post-translationally modified. Numerous thiopeptides have been identified; almost all of which inhibit protein synthesis in gram-positive bacteria. These intrinsic antimicrobial properties make thiopeptides promising candidates for the development of new antibiotics. The antimicrobial peptide micrococcin is a thiopeptide that is synthesized by the ribosome and undergoes several post-translational modifications (PTMs). Micrococcin is formed from a precursor peptide, TclE. TclE comprises an N-terminal leader (35-AA) that is crucial for recognition of the PTM machinery, alongside a C-terminal core sequence (14-AA) that undergoes multiple …

Radiofrequency Inactivation Of Salmonella In Black Pepper And Dried Basil Leaves Using In-Package Steaming, Surabhi Wason, Rossana Villa-Rojas, Jeyamkondan Subbiah

Department of Food Science and Technology: Faculty Publications

Radiofrequency (RF) heating has been extensively studied for pasteurizing low‐moisture foods. Currently, bulk foods are treated with radiofrequency; potential cross‐contamination may occur during packaging of pasteurized products. As an alternative, in‐package RF processing was evaluated for Salmonella inactivation on black peppercorns and dried basil leaves and prevention of cross‐contamination during storage postprocessing. Inpackage steaming refers to the process in which the samples were heated in a steam vent package to generate and retain steam during the treatment. This treatment achieved good heating uniformity which could be because of the circulation of steam within the package. One‐way steam vent allowed the …

The 14-Day Rule For In Vitro Human Embryo Research Requires Adjustment: From A Comprehensive Perspective Of Science, Ethics And Policy Research, Xiao Lu, Ming Zhao, Huihui Liu, Tianqing Li, Tao Tan, Weizhi Ji

Bulletin of Chinese Academy of Sciences (Chinese Version)

Since it was proposed, in vitro human embryo research had been following the 14-day rule, which limited in vitro research on human embryos within 14 days after fertilization. With the advancement in embryo culturing technology, this ethical rule has been greatly challenged. In 2021, the International Society for Stem Cell Research (ISSCR) recommended a conditional extension of the existing time limit in ISSCR Guidelines for Stem Cell Research and Clinical Translation, hence the international scientific community has restarted the debate on the 14-day rule. This study systematically analyzed the historical background and controversies of the 14-day rule ethical regulation of …

Wildland Resources Faculty Publications

Coyote (Canis latrans) range expansion into desert ecosystems has highlighted the role of anthropogenic water sources in arid ecosystems. Despite hypotheses that additional water facilitated this expansion, previous studies reported that coyotes did not exhibit a spatial or dietary response to removal of anthropogenic water. We used GPS data to examine if coyotes responded to water removal at a finer spatial scale than previously investigated. Our integrated step selection analysis did not find evidence that coyotes adjusted their distance to water following water removal. Vegetation was an important factor in habitat selection of coyotes, with riparian and agricultural …

Several alterations in fibroblast growth factor receptor (FGFR) genes have been found in breast cancer; however, they have not been well characterized as therapeutic targets. Futibatinib (TAS-120; Taiho) is a novel, selective, pan-FGFR inhibitor that inhibits FGFR1-4 at nanomolar concentrations. We sought to determine futibatinib's efficacy in breast cancer models. Nine breast cancer patient-derived xenografts (PDXs) with various FGFR1-4 alterations and expression levels were treated with futibatinib. Antitumor efficacy was evaluated by change in tumor volume and time to tumor doubling. Alterations indicating sensitization to futibatinib in vivo were further characterized in vitro.

A hallmark of inherited retinal degenerative diseases such as retinitis pigmentosa (RP) is progressive structural and functional remodeling of the remaining retinal cells as photoreceptors degenerate. Extensive remodeling of the retina stands as a barrier for the successful implementation of strategies to restore vision. To understand the molecular basis of remodeling, we performed analyses of single-cell transcriptome data from adult zebrafish retina of wild type AB strain (WT) and a P23H mutant rhodopsin transgenic model of RP with continuous degeneration and regeneration. Retinas from both female and male fish were pooled to generate each library, combining data from both sexes. …
