The Changing Cost Of Cattle Transportation, Elliott James Dennis
The Changing Cost Of Cattle Transportation, Elliott James Dennis
Center for Agricultural Profitability
Diesel is one of the primary inputs in the transportation of goods throughout the United States. Livestock hauling is no exception. Feeder cattle are generally transported long distances in the fall as they move from summer grazing to placement in backgrounding operations or directly into feedlots. Cattle, and other livestock in general, can handle transportation stress fairly well – to a point. Trucking feeder cattle long distances can impact animal health outcomes, and improper animal handling can lead to bruised or injured cattle. These negative impacts can generally be offset by appropriate stocking densities, proper trailer ventilation, correct animal handling …
Patch-Burn Grazing Impacts Forage Resources In Subtropical Humid Grazing Lands, Elizabeth H. Boughton, Nuria Gomez-Casanovas, Hilary Swain, Carl Bernacchi, Raoul K. Boughton, Keith Brinsko, Haoyu Li, Alan Rivero, Evan H. Delucia, Jed Sparks
Patch-Burn Grazing Impacts Forage Resources In Subtropical Humid Grazing Lands, Elizabeth H. Boughton, Nuria Gomez-Casanovas, Hilary Swain, Carl Bernacchi, Raoul K. Boughton, Keith Brinsko, Haoyu Li, Alan Rivero, Evan H. Delucia, Jed Sparks
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Subtropical humid grazing lands represent a large global land use and are important for livestock production, as well as supplying multiple ecosystem services. Patch-burn grazing (PBG) management is applied in temperate grazing lands to enhance environmental and economic sustainability; however, this management system has not been widely tested in subtropical humid grazing lands. The objective of this study was to determine how PBG affected forage resources, in comparison with the business-as-usual full-burn (FB) management in both intensively managed pastures (IMP) and seminative (SN) pastures in subtropical humid grazinglands. We hypothesized that PBG management would create patch contrasts in forage quantity …
Annotating Gene Expression And Regulatory Elements In Tissues From Healthy Thoroughbred Horses And Identifying Candidate Mutations Associated With Perosomus Elumbis In An Angus Calf, Alexa Barber
Department of Animal Science: Dissertations, Theses, and Student Research
Genome annotation has a direct impact on the success of genomic studies. Transcriptome analyses and chromatin immunoprecipitation and sequencing (ChIP-seq) have been used to functionally annotate genomes. These methods can identify protein-coding genes, non-coding transcripts, and cis-regulatory elements across the genome. The primary objective of the first study was to functionally annotate the equine genome through the assessment of nine tissues: adipose, brain, heart, lamina, liver, lung, skeletal, muscle, testis, and ovary. In the first project, 150 bp, paired-end RNA sequencing (RNA-seq) libraries were generated in stallion tissues and compared to previously generated mare RNA-seq libraries to quantify variation in …

Management-Intensive Grazing Impacts On Total Escherichia Coli, E. Coli O157: H7, And Antibiotic Resistance Genes In A Riparian Stream, Laura M. Rubeck, James E. Wells, Kathy Hanford, Lisa M. Durso, Walter H. Schacht, Elaine D. Berry
Department of Agronomy and Horticulture: Faculty Publications
The impacts of management-intensive grazing (MIG) of cattle on concentrations of total Escherichia coli, total suspended solids (TSS), and nitrate-nitrite nitrogen (NO3+NO2-N), and occurrence of E. coli O157:H7 and selected antibiotic resistance genes (ARGs) in stream water and/or sediments were evaluated. Cattle were grazed for twoweek periods in May in each of three years. Overall, grazing increased total E. coli in downstream water by 0.89 log10 MPN/100 mL (p < 0.0001), and downstream total E. coli concentrations were higher than upstream over all sampling intervals. Downstream TSS levels also increased (p ≤ 0.0294) during grazing. In contrast, there was …

Restoring The Fire–Grazing Interaction Promotes Tree–Grass Coexistence By Controlling Woody Encroachment, Jane F. Capozzelli, James R. Miller, Diane M. Debinski, Walter H. Schacht
Restoring The Fire–Grazing Interaction Promotes Tree–Grass Coexistence By Controlling Woody Encroachment, Jane F. Capozzelli, James R. Miller, Diane M. Debinski, Walter H. Schacht
Department of Agronomy and Horticulture: Faculty Publications
Woody encroachment can convert grasslands and savannas to shrublands and woodlands, so understanding the processes which regulate woody encroachment is necessary to conserve or restore these ecosystems.We hypothesized that recreating the fire–grazing interaction would limit woody encroachment because focal grazing increases fuel accumulation on unburned areas and increases browsing on emergent woody plants in burned areas. This study was conducted in the Grand River Grasslands of Iowa and Missouri (USA) on 11 sites (15.4–35.0 ha). Each site was assigned to one treatment: patch-burn-graze (n = 4), with spatially discrete prescribed fires and free access by cattle (the fire–grazing interaction); graze-andburn …
Effects Of Supplemental Whole Cottonseed On Weaned Calf Production, Zachary Debord
Effects Of Supplemental Whole Cottonseed On Weaned Calf Production, Zachary Debord
Mahurin Honors College Capstone Experience/Thesis Projects
This study compared the effect of supplemental whole cottonseed in a weaned calf ration on cattle productivity. Feed is the main cost for livestock production. Whole cottonseed supplementation may increase production and reduce the cost of gain for the ration. During the study, 18 beef calves were weaned and split into two groups and fed, with and without WCS, for 50 days to determine the effect of supplemental whole cottonseed. Productivity was determined by measuring average daily gains for each group and comparing cost of gain for each ration. It was determined that WCS did increase productivity of weaned calves …

Use Of Uav Imagery And Nutrient Analyses For Estimation Of The Spatial And Temporal Contributions Of Cattle Dung To Nutrient Cycling In Grazed Ecosystems, Amanda Shine
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Nutrient inputs from cattle dung are crucial drivers of nutrient cycling processes in grazed ecosystems. These inputs are important both spatially and temporally and are affected by variables such as grazing strategy, water location, and the nutritional profile of forage being grazed. Past research has attempted to map dung deposition patterns in order to more accurately estimate nutrient input, but the large spatial extent of a typical pasture and the tedious nature of identifying and mapping individual dung pats has prohibited the development of a time- and cost-effective methodology. The first objective of this research was to develop and validate …
Impact Of Feeding Distillers Grains Or Isolated Components In Distillers Grains To Growing And Finishing Cattle, And The Comparison Of Protein Content And In-Situ Digestibility Of Feeds Commonly Used In Feedlot Diets, Brianna B. Conroy
Department of Animal Science: Dissertations, Theses, and Student Research
The use of distillers grains originating from biofuel production has become widely used in feedlot diets. Distillers grains has been identified as having an increased feeding value relative to dry-rolled corn, in recent years the composition of distillers grains has begun to change due to greater refinement in the ethanol production process. Two feedlot trials were conducted to evaluate the contribution of fat, fiber, and protein from distillers grains in the diets of growing and finishing cattle. Growing steers were fed a grass hay-based ration, including a corn control diet compared to a diet containing modified distillers grains plus solubles, …

Medication Darts Are Gaining In Popularity - Do They Affect Meat Quality? Are There Risks?, David J. Wilson, Kerry A. Rood
Medication Darts Are Gaining In Popularity - Do They Affect Meat Quality? Are There Risks?, David J. Wilson, Kerry A. Rood
All Current Publications
Livestock, such as beef cattle or post-weaned dairy cattle that are not yet milking, are often relatively “tame” (sometimes the term tame may not apply very well) and can be readily approached within a few feet. However, without adequate restraint facilities or enough personnel, actually treating the livestock is often difficult and can become frustrating and dangerous to people and animals. A solution to this problem, which is being rapidly and increasingly adopted, is the use of medication darts. Nevertheless, many in the cattle industry are raising some concerns. What are some of the characteristics of medication darts? Is there …
Predicting Spatial Risk Of Wolf-Cattle Encounters On Rugged And Extensive Grazing Lands, Patrick R. Clark, Joe Chigbrow, Douglas E. Johnson, John Williams, Larry L. Larson, Tyanne Roland
Predicting Spatial Risk Of Wolf-Cattle Encounters On Rugged And Extensive Grazing Lands, Patrick R. Clark, Joe Chigbrow, Douglas E. Johnson, John Williams, Larry L. Larson, Tyanne Roland
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Cattle grazing lands in the mountainous western United States are rugged, complex, and extensive. Terrain, vegetation, and other landscape features vary greatly across space. Risk of wolf-cattle encounters and potential for depredation loss certainly differ spatially as consequence of this variability. Yet, our understanding of this spatial risk is quite poor and this knowledge gap severely hampers our abilities to manage wolf-livestock interactions and mitigate conflicts. During 2009-2011, a research study was conducted at four study areas (USFS cattle grazing allotments) in western Idaho to evaluate and predict risk of wolf-cattle encounters. Each year, a random sample of 10 lactating …

Quantification Of Macrophages And Mycobacterium Avium Subsp. Paratuberculosis In Bovine Intestinal Tissue During Different Stages Of Johne’S Disease, Caitlin J. Jenvey, Jesse M. Hostetter, Adrienne L. Shircliff, John Bannantine, Judith R. Stabel
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Johne’s disease is an enteric disease caused by the intracellular pathogen Mycobacterium avium subsp. paratuberculosis (MAP). Upon ingestion of MAP, it is translocated across the intestinal epithelium and may be killed by intestinal macrophages, or depending on the bacterial burden and immunological status of the animal, MAP may thwart innate defense mechanisms and persist within the macrophage. This study aimed to determine the numbers of macrophages and MAP present in bovine midileal tissue during different stages of infection. Immunofluorescent (IF) labeling was performed on frozen bovine midileal intestinal tissue collected from 28 Holstein dairy cows. The number of macrophages in …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Infection of the host with Mycobacterium avium subsp. paratuberculosis results in chronic and progressive enteritis that traverses both subclinical and clinical stages. The mechanism(s) for the shift from an asymptomatic subclinical disease state to advanced clinical disease is not fully understood. In the present study, naturally infected dairy cattle were divided into subclinical and clinical infection groups, along with noninfected control cows of similar parity, to study host immune responses in different stages of infection. Both infection groups had higher levels of secretion of gamma interferon (IFN-), tumor necrosis factor-alpha (TNF-), and interleukin-2 (IL-2) than control cows, whereas only clinical …

Cattle As Technological Interventions: The Gender Effects Of Water Demand In Dairy Production In Uganda, Elizabeth Ransom, Carmen Bain, Harleen Bal, Natasha Shannon
Sociology and Anthropology Faculty Publications
Smallholder dairy production dominates the country of Uganda, with over 90% of the national herd owned by smallholders. To reduce hunger, malnutrition, and raise families out of poverty agricultural development, interventions in Uganda have focused on increasing milk production through the introduction of improved dairy cow breeds. Development actors, such as the East Africa Dairy Development (EADD) program in Uganda, see crossbreed dairy cows as a key technological intervention for improving production. Drawing on a multi-method study (spatial analysis, surveys, and qualitative interviews) of dairy smallholders, our paper examines the gendered effects of the introduction of crossbreed dairy cows.

Economic Impact Evaluation Of Bovine Johne’S Disease (Bjd) Management Options In Western Australia, Ananda Ghose Dr, Leo Loth Dr, Mia Carbon Dr, Bruce Twentyman Dr
Biosecurity research reports
Bovine Johne’s disease (BJD) is an infectious disease of cattle caused by Mycobacterium avium subsp. paratuberculosis (Mptb) that can also affect other ruminants such as goats, alpaca, sheep and deer. It causes chronic wasting and incurable diarrhoea leading to deaths in mature cattle. Subclinically affected animals may have reduced growth and milk production levels.
The WA cattle industry needs to determine what level of protection from BJD incursion and spread is required for WA, including at the border, and how this is best achieved. The primary decision to be made is whether BJD is best managed on a statewide basis …

The Influence Of The Bovine Fecal Microbiota On The Shedding Of Shiga Toxin-Producing Escherichia Coli (Stec) By Beef Cattle, Nirosh D. Aluthge
Department of Food Science and Technology: Dissertations, Theses, and Student Research
During the past three decades, Shiga toxin-producing E.coli (STEC) have emerged as an important food safety concern. Although initially E. coli O157 was the main focus, recent outbreaks and resulting investigations have shown that certain non-O157 STEC are as much a threat to food safety as their O157 counterparts. To the beef industry, STEC have been of particular concern due to the frequent association of beef and beef products as vehicles of STEC infection. As a result, along with E. coli O157, six non-O157 STEC serogroups (known as the ‘big six’) are now regulated as adulterants in certain raw beef …
