Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty May 2021

Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty

Animal Science Undergraduate Honors Theses

This study will focus on how maternal phosphorus status of beef heifers affects the growth and performance of their calves. Heifers have been offered free-choice mineral with either 0 or 4% supplemental phosphorus from 30 days after weaning until calving. A study by H. Hilfiker, a University of Arkansas honors student, investigated the effects of these treatments from 30 days after weaning until 60 days after the breeding season when heifers were confirmed to be bred or open. For this developing heifer project 64 crossbred Angus heifers were assigned randomly into 8 groups (8 heifers/ group) before assigning each group …


Biogeography Of The Bovine Respiratory Microbiome And Its Relationship With Bovine Respiratory Disease, Jianmin Chai Dec 2020

Biogeography Of The Bovine Respiratory Microbiome And Its Relationship With Bovine Respiratory Disease, Jianmin Chai

Graduate Theses and Dissertations

Bovine respiratory disease (BRD) is the most common and costly disease in the beef cattle industry, leading to high morbidity, mortality and huge economic loss. Despite the recent advances in vaccination and antimicrobial techniques, no significant health-improved outcomes have developed. Due to a deep investigation of the microbiome, respiratory microbiotas are known to have important roles for host health and disease. However, BRD specific pathogens have not yet been identified since they are found in both healthy and diseased animals. A systemic and comprehensive study of the biogeography of the bovine respiratory microbiome and its relationship with BRD is lacking …

Effects Of Lasalocid And Energy Supplementation On Forage Intake, Energy Metabolism, And Performance Of Cattle Grazing Wheat Pasture, Autumn Tayler Pickett May 2020

Effects Of Lasalocid And Energy Supplementation On Forage Intake, Energy Metabolism, And Performance Of Cattle Grazing Wheat Pasture, Autumn Tayler Pickett

Graduate Theses and Dissertations

Cattle grazing wheat pasture have the potential to gain BW exceptionally well, but excessive nitrogen intake results in increased excretion and increased greenhouse gas (GHG) emissions. Supplemental concentrates with the addition of an ionophore given to ruminants grazing wheat is a potential practice for producers to increase nitrogen efficiency while decreasing GHG emissions. Therefore, the objective of this experiment was to quantify the effects of energy (2.95 kg/d) and lasalocid (200 mg/hd/d) supplementation on nutrient intake, energy metabolism, respiratory gas fluxes, and performance of grazing cattle. Methane emissions were not affected (P = 0.58) by treatment, hence methane intensity (P …


Associations Among Beef Cattle Genotypes, Neospora Caninum Infection, And Reproductive Performance, Ryan James Page May 2020

Associations Among Beef Cattle Genotypes, Neospora Caninum Infection, And Reproductive Performance, Ryan James Page

Graduate Theses and Dissertations

Reproductive performance is crucial for sustained financial success in the beef cattle industry. This dissertation includes a population study that quantified the incidence of Neospora caninum infections in the central region of the United States and tested its relationship with reproductive performance in beef cattle. Trial one of that study concluded that 6.9% of open, replacement heifers (n = 1306) tested seropositive. The second trial in that project found that 9.6% of the breeding age females (n = 500) tested were seropositive for Neospora caninum; and that state in which the cattle lived and age impacted (P < 0.05) infection rate. Breed composition, number of farm dogs on the ranch, and use of total mixed rations were not associated (P > 0.1) with seropositive …

Animal Science Undergraduate Honors Theses

Prolactin (PRL), melatonin (MTN), and dopamine (DA) are all hormones that are believed to play a role in the regulation and growth of hair in beef cattle. There are also single nucleotide polymorphisms associated with each of these hormones or their receptors, indicating that the investigation of these polymorphisms could allow them to serve as genetic markers for the future productivity of an animal. The objective of this study was to determine the relationships among cattle genotype, hair coat score, and productivity through the investigation of single nucleotide polymorphisms within prolactin, dopamine receptor D2, and melatonin receptor 1A. Body weights, …


Investigation Of Bacterial Taxa As Biomarkers Of Fescue Toxicosis And Heat Stress In Grazing Beef Cows, Sarah Katherine Chewning Aug 2018

Investigation Of Bacterial Taxa As Biomarkers Of Fescue Toxicosis And Heat Stress In Grazing Beef Cows, Sarah Katherine Chewning

Graduate Theses and Dissertations

Fescue toxicosis in grazing beef cattle is caused by consumption of Ergot alkaloids associated with tall fescue (toxic fescue) and is responsible for substantial economic loss to the U.S. beef industry. Cattle consuming toxic fescue suffer adverse physiological responses, such as: hyperthermia, increased respiration rate (RR), poor reproduction and growth performance. Other adverse responses to fescue toxins include the retention of a winter hair coat and vasoconstriction in the extremities, which can lead to tissue necrosis. Identifying cattle with reduced susceptibility to fescue toxins would allow for efficient use of fescue pastures; thus, the objectives of this thesis was to: …


Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, Tara S. Easter, Alexander K. Killion, Neil H. Carter Mar 2018

Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, Tara S. Easter, Alexander K. Killion, Neil H. Carter

Neil H. Carter

Information, energy, and materials are flowing over greater distances than in the past, changing the structure and feedbacks within and across coupled human and natural systems worldwide. The telecoupling framework was recently developed to understand the feedbacks and multidirectional flows characterizing social and environmental interactions between distant systems. We extend the application of the telecoupling framework to illustrate how flows in beef affect and are affected by social-ecological processes occurring between distant systems in Africa, and how those dynamics will likely change over the next few decades because of climate-induced shifts in a major bovine disease, trypanosomosis. The disease is …

Department of Child, Youth, and Family Studies: Faculty Publications

Background: SNPs are informative to estimate genomic breed composition (GBC) of individual animals, but selected SNPs for this purpose were not made available in the commercial bovine SNP chips prior to the present study. The primary objective of the present study was to select five common SNP panels for estimating GBC of individual animals initially involving 10 cattle breeds (two dairy breeds and eight beef breeds). The performance of the five common SNP panels was evaluated based on admixture model and linear regression model, respectively. Finally, the downstream implication of GBC on genomic prediction accuracies was investigated and discussed in …

Genetic Polymorphisms Of The Glucocorticoid Receptor And Interleulin-8 Receptor Genes And Their Relationship To Production Traits And Hair Coat Scores In Crossbred Cattle, Avery B. Deaton, Laura Meyer, Jeremy Powell, Charles F. Rosenkrans Jr.

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Little is understood about how the diversity of genes, specifically the glucocorticoid receptor (GR) and interleukin-8 receptor (CXCR2), are related to reproductive health and how this affects physical traits in cattle. Glucocorticoid receptors have been positively associated with higher milk yields, lactose content, feed intake, and feed conversion rates. Interleukin-8 genes are part of the innate immune response and help with many aspects of female reproductive health, such as protecting the embryo from the maternal immune system during pregnancy. The objective of this research was to identify polymorphisms in the GR and CXCR2 genes and to associate genotypes between the …

The purpose was to determine the effects of the physical dimensions of the pen and group size and stocking density on cow activity. Cows (randomly assigned to 4 groups of 6 animals each) were tested in pens with 24 or 12 lying places and in groups with 12 or 6 cows. All groups were tested in each of the 4 treatments with treatment order allocated using a 4 × 4 Latin square. The distance moved and the number of movements were calculated using 5-min scan sampling of video recordings over a 48-h period. Time spent lying down, number of lying …


Economic And Environmental Effects Of Switchgrass Production On A Representative Cow-Calf Farm In Middle Tennessee, Hanna Leah Watts May 2012

Economic And Environmental Effects Of Switchgrass Production On A Representative Cow-Calf Farm In Middle Tennessee, Hanna Leah Watts

Masters Theses

The purpose of this research was to evaluate the economic tradeoffs and land use dynamics of incorporating switchgrass into the farm plan of a representative middle Tennessee cow-calf operation. A net revenue simulation and multi-year mathematical programming model was used to find the optimum mix of switchgrass and cow-calf enterprises that will maximize whole farm net revenues over 30 years on a representative middle Tennessee beef farm under both average and above average management. Land use changes predicted by the mathematical programming model were used to assess the carbon change associated with incorporating, or transitioning to, switchgrass production.

Assessing Lameness In Cows Kept In Tie-Stalls, K. A. Leach, S. Dippel, J. Huber, S. March, C. Winckler, H. R. Whay

Housing and Confinement of Farm Animals Collection

Identifying lame cows and quantifying the prevalence of lameness are important elements of cattle welfare assessment that are generally achieved by methods involving observations of each animal walking. There is no published method for assessing lameness in cows confined in tie-stalls. The objective of this study (carried out within the European Commission’s Welfare Quality® project) was to develop a suitable method and validate it for lameness detection against a published locomotion score. A series of indicators of lameness visible in tied cows was formalized into a stall assessment protocol. This was validated against a traditional locomotion score and tested for …

Tail Docking Dairy Cattle: Effects On Cow Cleanliness And Udder Health, Cassandra B. Tucker, David Fraser, Daniel M. Weary Jan 2001

Tail Docking Dairy Cattle: Effects On Cow Cleanliness And Udder Health, Cassandra B. Tucker, David Fraser, Daniel M. Weary

Farm Animal Husbandry Collection

To determine whether tail docking would influence cow cleanliness and udder health in a free-stall system, we monitored milking cows after half the animals in a herd were docked. A sample of 223 docked and 190 undocked cows (reducing to 169 and 105 over the study as cows were dried off) were monitored for 8 wk. Cow cleanliness was scored in two areas: along the spine, and the rump adjacent to the tail at 1, 2, 3, 5, and 8 wk after docking. Cleanliness was evaluated by counting squares that were soiled (0 to 14 on a 5- × 17.5-cm …


Assessing Factors That May Predispose Minnesota Farms To Wolf Depredations On Cattle, L. David Mech, Elizabeth K. Harper, Thomas J. Meier, William J. Paul Jan 2000

Assessing Factors That May Predispose Minnesota Farms To Wolf Depredations On Cattle, L. David Mech, Elizabeth K. Harper, Thomas J. Meier, William J. Paul

USGS Northern Prairie Wildlife Research Center

Wolf (Canis lupus) depredations on livestock cause considerable conflict and expense in Minnesota. Furthermore, claims are made that such depredations are fostered by the type of animal husbandry practiced. Thus, we tried to detect factors that might predispose farms in Minnesota to wolf depredations. We compared results of interviews with 41 cattle farmers experiencing chronic cattle losses to wolves (chronic farms) with results from 41 nearby "matched" farms with no wolf losses to determine farm characteristics or husbandry practices that differed and that therefore might have affected wolf depredations. We also used a Geographic Information System (GIS) to …
