Impact Of Increasing Level Of Milk Production On Cow-Calf Performance In Nebraska Sandhills, Selby L. Boerman, Jacki A. Musgrave, Kathryn J. Hanford, Mitchell B. Stephenson, J. Travis Mulliniks

Nebraska Beef Cattle Reports

In a 2-yr study, data were collected on 118 crossbred cow-calf pairs from March and May-calving herds. On approximately 30, 60, 90, 120, and 210 d postpartum, individual cow 24-h bilk yield was estimated through weigh-suckle weigh techniques. Cow body weight (BW) and body condition score (BCS) were collected weekly through breeding. Calf BW was recorded at each milking. Individual cow milk area under the curve (AUC) values were calculated and data were analyzed using linear regression analysis. Results from this study illustrate that increasing total milk produced throughout the lactation period had minimal influence on the cow production parameters …

Understanding pathogen emergence in new host species is fundamental for developing prevention and response plans for human and animal health. We leveraged a large-scale surveillance dataset coordinated by United States Department of Agriculture, Animal and Plant Health Inspection Service and State Natural Resources Agencies to quantify the outbreak dynamics of SARS-CoV-2 in North American white-tailed deer (Odocoileus virginianus; WTD) throughout its range in the United States. Local epidemics in WTD were well approximated by a single-outbreak peak followed by fade out. Outbreaks peaked early in the northeast and mid- Atlantic. Local effective reproduction ratios of SARS-CoV-2 were between …

What Is Known, Unknown, And Needed To Be Known About Damage Caused By Wild Pigs, Kurt C. Vercauteren, Kim M. Pepin, Seth M. Cook, Sophie Mckee, Abigail Pagels, Keely J. Kohen, Ingrid A. Messner, Michael P. Glow, Nathan P. Snow

United States Department of Agriculture Wildlife Services: Staff Publications

Damage assessments provide evidence for initiating and evaluating management programs that protect natural resources and human livelihoods against invasive species. Wild pigs (Sus scrofa) cause extensive damage in their native and non-native ranges, but the extent of current damage and efficacy of management of the damage (i.e., population control of wild pigs, exclusion fencing, etc.) remains poorly described. We conducted a systematic review of physical damage caused by wild pigs to summarize what is known and identify knowledge gaps for damage assessment. Wild pig damage assessments have been overwhelmingly qualitative (84% of studies) and measured differently across studies, …

Tracking Sero-Molecular Trends Of Swine Brucellosis In Hawai'i And The Central Pacific, Thi Hai Au La, Ian A. Mcmillan, Prashant Dahal, Andrew H. Burger, Mahdi Belcaid, Darrin M. Phelps, Samuel M. Goldstein, Vienna R. Brown, Michael H. Norris

United States Department of Agriculture Wildlife Services: Staff Publications

Introduction

Brucellosis is a zoonotic disease of mammals caused by bacterial species of the Brucella genus. The reservoir for disease is typically mammals, with species of Brucella found infecting amphibians, bats, and marine mammals. Brucella spp. can pass directly to humans through contact with infected animals or their products. Brucella spp. can cause chronic debilitating infections in mammals, including humans, and is associated with spontaneous abortions in infected animals, causing reduced fecundity. In Hawai‘i, terrestrial species that could harbor Brucella spp. include swine, cattle, horses, and axis deer among others. The numerous feral swine in Hawai‘i are known to carry …

Classification Of Sow Postures Using Convolutional Neural Network And Depth Images, Md Towfiqur Rahman, Tami M. Brown-Brandl, Gary A. Rohrer, Sudhendu R. Sharma, Yeyin Shi

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The United States swine industry reports an average preweaning mortality of approximately 16% where approximately 6% of them are attributed to piglets overlayed by sows. Detecting postural transitions and estimating sows’ time budgets for different postures are valuable information for breeders and engineering design of farrowing facilities to eventually reduce piglet death. Computer vision tools can help monitor changes in animal posture accurately and efficiently. To create a more robust system and eliminate varying lighting issues within a day including daytime/ nighttime differences, there is an advantage to using depth cameras over digital cameras. In this study, a computer vision …

“The Direful Spectacle Of The Wrack”: Teaching Against Colonialism Through Shipwrecks And Shakespeare, Sara A. Rich

Journal of the National Collegiate Honors Council Online Archive

It has become increasingly apparent that anti-colonial and anti-racist pedagogies are necessary in higher education classrooms, and honors education as an experimental zone is an ideal place to test ideas that can be taken into the wider university community. Honors professors epitomize the teacher-scholar model, and this paper presents a six-year trajectory of anti-colonial pedagogy coupled with original interdisciplinary research in the social sciences, arts, and humanities. Bringing canonical Shakespeare into conversation with historical shipwrecks and their aftermath, students learn how The Tempest was written at a pivotal point in history, coincidentally situated in the same year as the earliest …

Gwayak Ateg Onaakonigewi Dibenjigewin: Decolonizing Jurisdiction In Anishinaabe Tribal Courts, Kekek Jason Stark

Nebraska Law Review

It is generally understood as a matter of federal Indian law that determinations of tribal law should properly be interpreted by tribal courts. This is because tribal courts do not always adhere to the same legal philosophy as their settler colonial counterparts. Many tribal courts subscribe to traditional law, which is an “essential source” of tribal jurisprudence. Anishinaabe communities have maintained a rich body of traditional tribal law since time immemorial. However, these customary law principles are only recently being included in modern-day Anishinaabe tribal court determinations. This Article builds upon the Anishinaabe law principles articulated in recent opinions and …

Calliphoridae Of Organ Pipe Cactus National Monument, Andrew Meeds

Department of Entomology: Distance Master of Science Projects

This project aimed to establish a baseline understanding of the blow fly fauna of Organ Pipe Cactus National Monument (OPCNM). Blow flies are the most commonly used insect in criminal investigations due to their tendency to be the earliest to locate and colonize remains. By understanding their distributions and patterns of seasonality, forensic entomologists can determine which species are most likely to colonize remains and identify which species may require further study. An 11-month comparison between fresh and aged chicken liver-baited traps improves understanding of primary and secondary colonizers in Organ Pipe Cactus National Monument and offers insights into effective …

Integrated Pest Management Of Maple (Acer) In Midwest Nursery Production, Darcey Hickey

Department of Entomology: Distance Master of Science Projects

Introduction

In all agricultural settings, damage from arthropod pests is inevitable. Integrated Pest Management (IPM) was introduced in the 1970’s as a response to increased public awareness of the hazardous effects of pesticides in the environment (Frazier, 2010). Ornamental nursery production is an important sector of US agriculture. In ornamental nurseries, pest damage is the leading cause of revenue loss (Braman et al., 2015). IPM has primarily been implemented for agricultural settings and as IPM is specific to each environment, it is important to explore the use of IPM practices in nursery production. As nurseries are found across the United …

Evolution Of The Largest Insect Orders: A Comprehensive Literature Review, Jason Thompson

Department of Entomology: Distance Master of Science Projects

Introduction

Insects are regarded by many to be among the most successful organisms on earth, displaying remarkable diversity, resilience, and adaptations, allowing them the ability to inhabit and exploit a wide array of niche environments. If sheer numbers are utilized as a yardstick by which to measure success, it has been estimated that there may be as many as 10 quintillion insects alive and active at any given time (Sabrosky, 1952). In terms of species diversity, estimates have ranged from as many as 30 million based on research and collections in tropical forest canopies (Erwin, 1982) to more recent, conservative …

Genetic Tracking Of A Rabid Coyote (Canis Latrans) Detected Beyond A Rabies Enzootic Area In West Virginia, Usa, Matthew W. Hopken, Crystal Gigante, Amy T. Gilbert, Richard B. Chipman, Jordana D. Kirby, Rene Edgar Condori, Samuel Mills, Chelsea Hartley, John Forbes, Lisa Dettinger, Dongxiang Xia, Yu Li, Bridgett Vonholdt

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife translocation and cross-species transmission can impede control and elimination of emerging zoonotic diseases. Tracking the geographic origin of both host and virus (i.e., translocation versus local infection) may help determine the most effective response when high-risk cases of emerging pathogens are identified in wildlife. In May 2022, a coyote (Canis latrans) infected with the raccoon (Procyon lotor) rabies virus variant (RRV) was collected in Lewis County, West Virginia, USA, an area free from RRV. We applied host population genomics and RRV phylogenetic analyses to determine the most likely geographic origin of the rabid coyote. Coyote …

Presenting Past People: Storytelling Through Prehistoric Garment Reconstructions, Floor Huisman, Anna Zimmermann, Ronja Lau, Karina Grömer

Textile Crossroads: Exploring European Clothing, Identity, and Culture across Millennia

This paper argues that we need to focus on past people (rather than just objects) in our narratives and museum displays to engage museum visitors more effectively. It will demonstrate that we can use a combination of well-researched physical and digital prehistoric garment reconstructions to implement more people-centered approaches also used in living history, which bring the past to life and allow visitors to literally come face-to-face with long-dead people. In this way, visitors can relate to past people on an emotional level, which helps them to learn much more about past life than many traditional displays. After outlining how …
