Ruminant production systems are major contributors to greenhouse gases emissions, with animal feeding practices being the main cause for methane and nitrous oxide’s release. Although feeding animals forages has been proven to be more sustainable, traditional ryegrass monocultures still require a lot of input (e.g., fertilisers and pesticides). Multi-species swards, consisting of different swards, such as grasses, forage legumes and herbs, need less management and fertiliser, produce more dry matter, and also add a variety of phytochemicals into the animal diet. In particular, polyphenols have been associated with a positive impact on animal health and productivity. However, data on the …
Let Emerging Plant Diseases Be Predictable, Valeria Trivellone
Let Emerging Plant Diseases Be Predictable, Valeria Trivellone
MANTER: Journal of Parasite Biodiversity
A prevalent concept for colonization and evolution among plant pathogens and their hosts stems from a post-Darwinian paradigm rooted in the formalized assumption of “specialized parasitism.” Seminal studies on rust fungi of socioeconomic importance integrated such an evolutionary perspective driven by the assumption of strict coevolution among pathogens and their plant hosts. Following this fundamentally unfalsifiable assumption, theories regarding host-switching for parasites were dismissed. If colonization occurred, this process would depend upon the origin of specific and novel mutations that allow infections of previously unexploited hosts or host groups, the acquisition of a broader host range. After a specific mutation …

An Emerging Infectious Disease Surveillance Platform For The 21st Century, Eloy Ortiz, Alicia Juarrero
MANTER: Journal of Parasite Biodiversity
Current vector surveillance programs are insufficient for coping with the emerging infectious disease crisis. In particular, current practices do not deploy sufficient information technology (IT) tools to generate actionable insights that can inform interventions and contain and mitigate the spread of vector-borne diseases. VectorAnalytica has developed a highly configurable and adaptable IT platform that imports, harmonizes, and integrates a range of data sources. The state-of-the-art backend development allows users to fully appreciate and understand the complexity of infectious disease dynamics without having to resort to additional statistical and GIS software packages. The platform yields actionable insights into outbreak patterns of …

Taking Action: Turning Evolutionary Theory Into Preventive Policies, Orsolya Molnár, Marina Knickel, Christine Marizzi
MANTER: Journal of Parasite Biodiversity
The emerging infectious disease (EID) crisis has been challenging global health security for decades, dealing substantial damage to all socioeconomic landscapes. Control measures have failed to prevent or even mitigate damages from an accelerating wave of EIDs, leading to the emergence and devastation caused by the COVID-19 pandemic. In the wake of the pandemic, we must critically review our public health policies and approaches. Current health security measures are based on the evolutionary theorem of host-parasite coevolution, which falsely deems EIDs as rare and unpredictable. The DAMA protocol (Document, Assess, Monitor, Act) is nested in a novel evolutionary framework that …
The Stockholm Paradigm Explains The Dynamics Of Darwin’S Entangled Bank, Including Emerging Infectious Disease, Salvatore J. Agosta
The Stockholm Paradigm Explains The Dynamics Of Darwin’S Entangled Bank, Including Emerging Infectious Disease, Salvatore J. Agosta
MANTER: Journal of Parasite Biodiversity
Pathogens and their hosts are embedded within the larger biosphere, what Darwin called the “entangled bank.” Emerging infectious disease occurs when a parasite “switches” to a new host. Understanding the dynamics of emerging disease requires understanding the dynamics of host-switching, which requires a more general understanding of how the biosphere and its constituent members cope when conditions change. The Stockholm paradigm is an integrative evolutionary framework that describes how living systems cope with change by oscillating between exploiting and exploring the geographical and functional dimensions of their environments. It combines organismal capacity, ecological opportunity, and the repeated external perturbations to …

One Health programs and trajectories are now the apparent standard for exploring the occurrence and distribution of emerging pathogens and disease. By definition, One Health has been characterized as a broadly inclusive, collaborative, and transdisciplinary approach with connectivity across local to global scales, which integrates the medical and veterinary community to recognize health outcomes emerging at the environmental nexus for people, animals, plants, and their shared landscapes. One Health has been an incomplete model, conceptually and operationally, focused on reactive and response-based foundations, to limit the impact of emerging pathogens and emerging infectious diseases and, as such, lacks a powerful …

Effect Of Dietary Urea In Gestating Beef Cows: Circulating Metabolites, Morphometrics, And Mammary Secretions, Ligia D. Prezotto, Jennifer F. Thorson
Department of Animal Science: Faculty Publications
Prolific use of supplementation strategies, including the utilization of urea, are practiced in beef cattle production systems. Unfortunately, the influence of urea supplementation on metabolics, adipose tissue mobilization, and mammary secretions is limited in beef cows. Therefore, the objectives of this experiment were to assess the influence of urea supplementation on metabolic profiles, morphometrics, and mammary secretions. Pregnant, multiparous beef cows were fed individually and assigned to treatment (n = 4/treatment) as Control or Urea Supplementation. Blood samples and body weight were collected every 28 d throughout gestation. Backfat thickness was measured via ultrasonography on days 28 and 280 of …

The objective was to evaluate the effects of high-pressure processing (HPP) levels on retail color of dark-cutting beef. Eight USDA Choice (mean pH = 5.5; normal-pH beef) and 12 dark-cutting (mean pH = 6.3) strip loins were obtained from a commercial packing plant within 2 d of harvest. Dark-cutting loins were cut into equal sections, vacuum packaged, and randomly assigned to 0 (no HPP), 300, 450, and 600 MPa of pressure for 90 s using chilled water. Following 48 h of dark storage at 2°C, dark-cutting loin sections were cut into 1.9-cm-thick steaks, placed in Styrofoam trays overwrapped in polyvinyl …

The Evolutionary Dynamics Of Infectious Diseases On An Unstable Planet: Insights From Modeling The Stockholm Paradigm, Angie T.C. Souza, Sabrina B.L. Araujo, Walter A. Boeger
MANTER: Journal of Parasite Biodiversity
Emerging infectious diseases (EIDs) are, besides a question of food safety and public health, an ecological and evolutionary issue. The recognition of this condition combined with the accumulation of evidence that pathogens are not specialists in their original hosts evidences the need for understanding how the dynamics of interaction between pathogens and hosts occurs. The Stockholm Paradigm (SP) provides the theoretical fundaments to understand the dynamics of diseases and design proactive measures to avoid the emergence and reemergence of infectious diseases. In this review, we revisit the models that evaluate several aspects of the proposed dynamics of the SP, including …

The reservoir for zoonotic o’nyong-nyong virus (ONNV) has remained unknown since this virus was first recognized in Uganda in 1959. Building on existing evidence for mosquito bloodfeeding on various frugivorous bat species in Uganda, and seroprevalence for arboviruses among bats in Uganda, we sought to assess if serum samples collected from bats in Uganda demonstrated evidence of exposure to ONNV or the closely related zoonotic chikungunya virus (CHIKV). In total, 652 serum samples collected from six bat species were tested by plaque reduction neutralization test (PRNT) for neutralizing antibodies against ONNV and CHIKV. Forty out of 303 (13.2%) Egyptian rousettes …

The Invisible Meat Microcosmos - Investigations Of Processed Meats' Specific Spoilage Organisms, Rebecca Furbeck
Department of Animal Science: Dissertations, Theses, and Student Research
As humankind grows in population, so will our need to compete against bacterial populations which spoil foodstuffs before we are able to consume them. This dissertation aims to identify the bacterial communities responsible for meat spoilage, and the mechanisms that govern the behaviors of these organisms. The literature review summarizes the state of knowledge regarding factors that influence meat microbiome composition, and how analytical methods can influence research outcomes. Study 1 aimed to identify the impact of additional ingredients and processing steps on the microbial ecology of processed turkey products. The main specific spoilage organisms (SSOs) belonged to the orders …
Molecular Mechanisms Underlying Aberrant Circulating Steroid Hormones In Gnrhr-Ii Knockdown Boars And Their Control Littermates, Dorothy Elsken
Molecular Mechanisms Underlying Aberrant Circulating Steroid Hormones In Gnrhr-Ii Knockdown Boars And Their Control Littermates, Dorothy Elsken
Department of Animal Science: Dissertations, Theses, and Student Research
Swine are the only livestock species that produce a functional protein for both GnRH-II and its receptor (GnRHR-II). Our laboratory reported that the interaction between GnRH-II and GnRHR-II facilitates testosterone production, independent of LH stimulation. To further examine GnRHR-II function, we developed a swine line with 70% reduced GnRHR-II mRNA levels (GnRHR-II KD) compared to control littermates. Mass spectrometry analysis of serum revealed that circulating levels of gonadal steroids were reduced in mature transgenic vs. control boars. Paradoxically, evaluation of testicular tissue indicated no difference between lines for gonadal steroid hormone levels. To address a potential cause for this discrepancy, …
Variance Component Estimates For Growth Traits In Beef Cattle Using Selected Variants From Imputed Low-Pass Sequence Data, Chad A. Russell
Variance Component Estimates For Growth Traits In Beef Cattle Using Selected Variants From Imputed Low-Pass Sequence Data, Chad A. Russell
Department of Animal Science: Dissertations, Theses, and Student Research
A beef cattle population (n=2,343) was used to assess the impact of variants identified from imputed low-pass sequence (LPS) on the estimation of variance components and genetic parameters of birth weight (BWT) and post weaning gain (PWG). Variants were selected based on functional impact and were partitioned into four groups (Low, Modifier, Moderate, High) based on predicted functional consequences and re-partitioned based on consequence of mutation, such as missense and untranslated region variants, into six groups (G1-G6). Each subset was used to construct a genomic relationship matrix (GRM) for univariate animal models. Multiple analyses were conducted to compare the proportion …

The Nebraska 4-H Equine Advancement Level Program’S Role In Positive Youth Development Using The Five Cs Model: An Exploratory Study, Eunhye Mccarthy
Department of Animal Science: Dissertations, Theses, and Student Research
Positive youth development (PYD) focuses on developing the strengths of youth through positive activities and behaviors rather than reducing negative tendencies. A well-researched model of PYD is the five C’s model that is popularly used in youth development organizations such as 4-H. The Nebraska 4-H Equine Advancement Level program was intended to serve as a guidebook for instruction and assessment of youth as they learn more about horses and horsemanship skills. Each of the four levels has an emphasis in developing a 4-H member’s responsibility, self-discipline, self-reliance, patience, and pride of accomplishments. The program was started approximately 30 years ago …
Environmental Determination Of Gastrointestinal Parasitism In Katahdin Sheep, Brian Arisman
Environmental Determination Of Gastrointestinal Parasitism In Katahdin Sheep, Brian Arisman
Department of Animal Science: Dissertations, Theses, and Student Research
Gastrointestinal nematodes (GIN) negatively affect the performance and wellbeing of sheep and are difficult to control due to anthelmintic resistance. Producers are therefore choosing breeds naturally resistant to GIN infection, such as the Katahdin. Katahdin are raised in various climates and management systems in the U.S., and those environmental factors can be combined into eco-management clusters. We hypothesized that GIN challenge varies predictably based on the characteristics of these clusters. Katahdin producers from across the U.S. were surveyed for management information. Body weights (BW), fecal egg counts (FEC) and FAMACHA scores (FAM) were collected on 3,527 Katahdin lambs around 90 …
Occurrence Of Bat Species At Water Sources In Two Urban Parks In Nashville, Tennessee, Maya Kiev, Austin Farris, Evan Mason
Occurrence Of Bat Species At Water Sources In Two Urban Parks In Nashville, Tennessee, Maya Kiev, Austin Farris, Evan Mason
Science University Research Symposium (SURS)
Animal behavioral patterns can shift due to anthropogenic factors related to pollution, human impact on flora/fauna, and changes in local water sources. While sound pollution can impact the occurrence of bats in urban areas, other factors could also influence bat behavior. This study examines bat occurrence near a water source at two urban parks in Nashville, Tennessee: one is in a highly trafficked area while the other is secluded and bordered by a suburban neighborhood. Both parks have small ponds, numerous trees, and open green spaces. Echo Meter Touch 2 devices were used to capture bat echolocation data at each …
Comparison Of Kanamycin-Resistant Bacteria In Earthworm Digestive Tracts And Soil From Compost Bins, Samantha Dooyema, Martin Dolan, Abigal Morse
Comparison Of Kanamycin-Resistant Bacteria In Earthworm Digestive Tracts And Soil From Compost Bins, Samantha Dooyema, Martin Dolan, Abigal Morse
Science University Research Symposium (SURS)
Antibiotic-resistant bacteria are becoming more prevalent in soil as humans have increased impacts on the environment. Previous research proposed that earthworms could affect bacteria distribution as soil is ingested and filtered through their bodies. This research aims to see if kanamycin-resistance bacteria is the same in earthworm digestive tracts as in the soil the earthworms inhabit. We expect that the gut contents and soil will vary in the occurrence of kanamycin-resistant bacteria. Earthworms and composted soil samples were collected from compost bins at a residential home in Nashville, Tennessee. Digestive tracts were dissected from the earthworms and homogenized. Kanamycin-resistant bacteria …

Aquaculture In Africa: Aquatic Animal Welfare, Impact On The Environment And The Sustainability Of The Sector, Mwenda M. Mbaka, Janice H. Cox, Stephen Ronan
Aquaculture
The African aquaculture sector recorded the fastest growth in the world between 2006-2018, averaging 10% or more, and is expected to partially fill the growing fish supply-demand gap up to 2063. In 2018, there were about 1.2 million aquafarmers across the continent, an increase from 920 thousand in 2014. According to the African Development Bank, expansion of aquaculture in Africa is hampered by "the overwhelming predominance of tilapia farming, which relies heavily on the production of fingerlings from a limited number of genetically improved strains that are resistant to the many diseases affecting this species, and on the production of …

Remembering Clem Klaphake, Don Paseka
Nebraska Bird Review
Clement (Clem) Klaphake passed away on December 30, 2022, from complications of Parkinson’s disease, which he struggled with for several years. He was born in Melrose, Minnesota, in 1943 and grew up working on his parents’ dairy farm, which included the usual menagerie of other farm animals typical of that time. Perhaps it was the routine of milking twice a day, seven days a week, or the impressive scar on his leg from a boar tusk, but Clem was destined to leave the farm and become a life-long educator. ... After getting his degree in 1971, Clem was hired to …
