Books, Boots, And Beer Halls In Germany: Observations By A Young Nebraskan Studying In Europe, 1876–1878, George Elliott Howard, Michael R. Hill

Zea E-Books Collection

Long before George Elliott Howard (1849–1928) became one of Nebraska’s premier sociologists and was elected president of the American Sociological Association (1917), he was a footloose young scholar who pursued postgraduate education in Germany during 1876–1878. Eager to share his adventures, Howard wrote and dispatched seven insightful essays that were quickly published in Nebraska newspapers. Here, collected together for the first time, are Howard’s firsthand observations on travel in Europe, life and learning in Germany, studying the German language, student beer-drinking societies, and a walking tour in Austria. Edited and introduced by Michael R. Hill, Howard’s essays are placed squarely …

Relationship Between Socking Rate And Production Of Stocker Hybrid Tilapia And Water Quality In A Mixtotrophic Biofloc System, Bartholomew W. Green, Steven D. Rawles, Candis L. Ray, Matthew E. Mcentire

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Intensified production of stocker-size tilapia can be accomplished using the biofloc technology production system. Stocker-size tilapia (ca. 10–200 g/fish) are raised for subsequent stocking for grow-out to market size. The relationship between stocking rate and the production of stocker-size hybrid tilapia (Oreochromis aureus x O. niloticus) was evaluated in two studies in outdoor mixotrophic biofloc tanks. Hybrid tilapia were stocked in 18.6-m² (15.7-m³) tanks at 50–150 fish/m² (59–178 fish/m³) in 25 fish/m² (30 fish/m³) increments in Study 1 and grown for 141–143 days. Stocking rates evaluated in 4.7-m …

Statistics Used In The Nebraska Beef Reports And Their Purpose, University Of Nebraska-Lincoln

Nebraska Beef Cattle Reports

The purpose of beef cattle and beef product research at UNL is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc) of beef production. Obviously, the researcher cannot apply treatments to every member of a population; therefore he/she must sample the population. The use of statistics allows the researcher and readers of the Nebraska Beef report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the major statistics used in the beef report. For a more detailed description of …

Evaluation Of Vivalto® On Growth Performance And Carcass Characteristics In Growing And Finishing Beef Steers, Garrett N. Lemon, Rebecca Mcdermott, Galen E. Erickson, Jeff Heldt, Pablo L. Loza

Nebraska Beef Cattle Reports

A finishing trial conducted at the Pan-handle Research, Extension, and Education Center (PREEC) near Scottsbluff, NE evaluated the effect of Vivalto^®, a B-vitamin complex, on the feeding performance and carcass characteristics of feedlot steers. The design of the study was completely randomized block design with three treatments, control without Vivalto^®, 1g Vivalto^®/steer/day, and 2g Vivalto^®/steer/day. Cattle fed the diets that included Vivalto^® feed had lower intakes during the first 56 days than cattle that received no Vivalto^® in the diet. No significant differences were observed for ADG, intake, feed efficiency …

Effect Of Biochar On Enteric Methane Production And Cattle Performance, Hanna Cronk, Holly Heil, Rebecca Mcdermott, Mitch Norman, Galen E. Erickson, Andrea Watson

Nebraska Beef Cattle Reports

Methane is a more potent greenhouse gas than carbon dioxide. Because ruminant animals, including cattle, emit methane, strategies are actively being sought to reduce these emissions. Pistachio shell-sourced biochar was included at 0.5% of a finishing cattle diet to determine effects on methane emissions and cattle performance. Eight pens of cattle were rotated through a 2-chambered emissions barn to analyze methane and carbon dioxide produced by the cattle. Biochar tended to increase methane emissions on a g/d basis with no effect on methane emissions as g/lb of feed intake and no differences in carbon dioxide emissions. There were no differences …

Impact Of Strip-Grazing Stockpiled Annual/Cover Crop Forages On Carrying Capacity And Animal Performance, Shelby L. Davies-Jenkins, Abigail Sartin, Devin Jakub, Zac Carlson, Erin Laborie, Jack Arterburn, Ben Beckman, Brad Schnick, M. E. Drewnoski

Nebraska Beef Cattle Reports

Annual forages/cover crops can be used to fill the fall/winter grazing gap, and strip grazing may increase carrying capacity by reducing trampling losses of the forage. The current experiment utilized a series of on-farm experiments across two growing seasons to compare continuous and strip grazing of various summer planted cover crops. Strip grazing increased carrying capacity by an average of 47 ± 15% and gain per acre by 44 ± 5% compared to continuous grazing although significant variability in the amount of increase was observed. This variability can likely be attributed to forage type (quality), frequency of moves, and forage …

Strategies For Ddgs Supplementation Frequency To Frazing Yearling Streers, Sydney T. Vanderhoff, Rebecca L. Sjostrand, Mitchell M. Norman, Isaque F. Vicci, Jim C. Macdonald, Mary E. Drewnoski

Nebraska Beef Cattle Reports

Infrequent supplementation saves labor and may reduce animal performance, but recent research with reduced fat distillers grains has provided inconsistent results. This experiment evaluated the effects of daily and three times a week supplementation of dried distillers grains on yearling steer performance grazing smooth bromegrass pastures from May to August. Daily supplemented steers received 5.6 pounds of dry matter per steer of dried distillers grains with solubles 7 days/week. The three times a week supplemented steers received 13.0 pounds of dry matter per steer of dried distillers grains with solubles three days/week (Monday, Wednesday, Friday). A control treatment received no …

Effect Of Methionine Supplementation During Late Gestation In Beef Females, Landon F. Tadich, Jim R. Teichert, Kathryn J. Hanford, Jacki A. Musgrave, Rich N. Funston

Nebraska Beef Cattle Reports

Some amino acids are known to be essential to cattle and effect protein availability to the animal, especially during gestation when nutrient requirements are higher. Methionine is found to be one of the most limiting in low quality forage diets. Two 3-yr studies were performed to evaluate the impact of methionine supplementation during late gestation on intake, body weight, average daily gain, and subsequent calf performance in primiparous and multiparous females. In exp 1, 120 artificially inseminated pregnancy heifers were placed in a Calan gate feeding system (n=40/yr) and assigned 1 of 3 treatments during late gestation and fed ad …

Artificial Insemination Of Beef Heifers With Multi-Sire Semen, Dempster Christenson, Jordan Thomas, Daniel J. Kelly, John G. Maddux, R. Funston

Nebraska Beef Cattle Reports

The study compared pregnancy rates of beef heifers artificially inseminated with multi-sire semen to single-sire semen at ranch 1 and demonstrated pregnancy to multi-sire sexed semen at rand 2. It was hypothesized pregnancy rates resulting from multi-sire semen would be increased compared to single-sire semen. Ranch 1 heifers were inseminated with either single-sire or multi-sire semen and all heifers expressing estrus at ranch 2 were inseminated with multi-sire semen averaged numerically greater pregnancy rate than the average single-sire pregnancy rate and pregnancy outcomes from multi-sire sexed semen exceed previous literature but cannot be directly compared. Despite similar pregnancy results between …

Long-Term Performance Of Steers Grazing Smooth Bromegrass Pastures, Morgan Hodges, Holly Heil, Rebecca Mcdermott, Anastasios Mazis, Tala Awada, Galen E. Erickson, Andrea K. Watson

Nebraska Beef Cattle Reports

Summary with Implications

Body weight gain of yearling steers grazing smooth bromegrass pastures was measured across 17 years from 2005 to 2021. Three treatments were applied, (1) control pastures with no additional inputs, (2) pastures fertilized with 80 lb of N per acre, and (3) pastures grazed with cattle supplemented daily with approximately 5 lb of dry distillers grains. The cnntrol treatment pastures (1.4 acres/steer) were stocked 30% lighter than the fertilized and supplemented pastures (1.0 acre/steer). Across the 17 years, the supplemented cattle gained 2.24 lb/day while the non-supplemented cattle (both control and fertilized treatments) gained 1.57 lb/day. Body …

A Science Teacher’S Experiences When Fostering Intercultural Competence Among Students In Multilingual Classrooms: A Narrative Study, Uma Ganesan, Amanda R. Morales

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Increased globalization of the world economy, growth in human migration, and rapid devel-opments in science and technology have required people to develop intercultural commu-nication skills. Teachers play a crucial role in developing intercultural competence among students in our globalized, multilingual classrooms. The need for fostering collaborative discourse among students with diverse cultural and linguistic repertoires and building in-tercultural competence among students is a common blind spot in Science, Technology, Engineering, and Mathematics teacher praxis. This can inhibit efforts to cultivate safe and supportive learning environments for all students and can ultimately threaten multilingual student success. As part of a larger …

Life Cycle Greenhouse Gas Emissions In Maize No-Till Agroecosystems In Southern Brazil Based On A Long-Term Experiment, Guilherme Rosa Da Silva, Adam J. Liska, Cimelio Bayer

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Brazilian agriculture is constantly questioned concerning its environmental impacts, particularly greenhouse gas (GHG) emissions. This research study used data from a 34-year field experiment to estimate the life cycle GHG emissions intensity of maize production for grain in farming systems under no-tillage (NT) and conventional tillage (CT) combined with Gramineae (oat) and legume (vetch) cover crops in southern Brazil. We applied the Feedstock Carbon Intensity Calculator for modeling the “field-to-farm gate” emissions with measured annual soil N₂O and CH₄ emissions data. For net CO₂ emissions, increases in soil organic C (SOC) were applied as a proxy, …

Instrumental Assessment Of Aero-Resistive Expiratory Muscle Strength Rehabilitation Devices, Angela M. Dietsch, Rahul Krishnamurthy, Kelsey Young, Steven M. Barlow

Department of Special Education and Communication Disorders: Faculty Publications

Purpose

Expiratory muscle strength training (EMST) is increasingly being used to treat voice, cough, and swallowing deficits in a wide range of conditions. However, a multitude of aero-resistive EMST models are commercially available, and the absence of side-by-side comparative data interferes with clinicians’ ability to assess which model is best suited to a particular client’s needs. The primary aim of this research was to test and compare the pressure and flow parameters of six currently available EMST models to help inform clinical decision making.

Method

We identified and tested five devices of each of six different EMST models to generate …

Applications Of Chemical Bird Repellents For Crop And Resource Protection: A Review And Synthesis, Shelagh T. Deliberto, Scott J. Werner

United States Department of Agriculture Wildlife Services: Staff Publications

Non-lethal repellents are needed to protect newly planted and ripening crops, to prevent valuable resources from being damaged by some wild birds worldwide. We systematically searched all scientific publications, patents and product registrations to developa current review and synthesis regarding chemical bird repellents for wildlife researchers, ecologists, managers, and conservationists. We then developed a database regarding the testing procedures and repellency results associated with the published and unpublished literature. For this comprehensive database, we developed an ‘index of success,’ or relative efficacy level (e.g. effective in most experiments), associated with each tested bird repellent. We found 345 papers published in …

One Health recognizes the health of humans, agriculture, wildlife, and the environment are interrelated. The concept has been embraced by international health and environmental authorities such as WHO, WOAH, FAO, and UNEP, but One Health approaches have been more practiced by researchers than national or international authorities. To identify priorities for operationalizing One Health beyond research contexts, we conducted 41 semi-structured interviews with professionals across One Health sectors (public health, environment, agriculture, wildlife) and institutional contexts, who focus on national-scale and international applications. We identify important challenges, solutions, and priorities for delivering the One Health agenda through government action. Participants …

Changing Fire Regimes And Nuanced Impacts On A Critically Imperiled Species, Jeremy T. Rockweit, Katie M. Dugger, Damon B. Lesmeister, Raymond J. Davis, Alan B. Franklin, J. Mark Higley

United States Department of Agriculture Wildlife Services: Staff Publications

Wildfire activity throughout western North America is increasing which can have important consequences for species persistence. Native species have evolved disturbance-adapted traits that confer resilience to natural disturbance provided disturbances operate within their historical range of variability. This resilience can erode as disturbance regimes change and begin operating outside this range. We assessed wildfire impacts during 1987–2018 on the northern spotted owl, an imperiled species with complex relationships with late and early seral forest in the Pacific Northwest, USA. We analyzed population- and individual-level wildfire impacts across the frequent-fire portion of the owl’s geographic range at two spatial scales and …

Heating animal decoys to mimic thermal signatures for drones

Abstract

Thermal sensors mounted on drones (unoccupied aircraft systems) are popular and effective tools for monitoring cryptic animal species, although few studies have quantified sampling error of ani- mal counts from thermal images. Using decoys is one effective strategy to quantify bias and count accuracy; however, plastic decoys do not mimic thermal signatures of representative species. Our objective was to produce heat signatures in animal decoys to realistically match thermal images of live animals obtained from a drone-based sensor. We tested commercially available methods to heat plastic decoys of …

Competitive Behaviors Between Black Vultures (Coragyps Atratus) And Turkey Vultures (Cathartes Aura) During Scavenging / Comportamientos Competitivos Entre Coragyps Atratus Y Cathartes Aura Durante El Carroñeo, Amanda M. Herbert, Patrick A. Zollner, Landon R. Jones, Marian L. Wahl, Grant N. Burcham, Bryan M. Kluever, Lee A. Humberg, Brandon M. Quinby

United States Department of Agriculture Wildlife Services: Staff Publications

Abstract

Interference competition occurs when an individual prohibits another’s access to a resource through antagonistic interactions. Despite considerable research on scavenger interactions at carrion, the limited evidence for competitive interactions between black vultures (Coragyps atratus) and turkey vultures (Cathartes aura) relies upon the frequency of antagonistic interactions without considering other forms of competition. Using remote cameras, we recorded the duration of aggression, scavenging, and vigilance behaviors exhibited by individual black vultures and turkey vultures scavenging stillborn domestic cattle carcasses within flocks composed of one or both vulture species. We tested for differences of durations of each …
