For genomic selection to be successful, there must be sufficient linkage disequilibrium between the markers and the causal mutations. The objectives of this study were to evaluate the extent of LD in ovine using the Santa Inês breed and to infer the minimum number of markers required to reach reasonable prediction accuracy. In total, 38,168 SNPs and 395 samples were used. The mean LD between adjacent marker pairs measured by r² and |D′| were 0.166 and 0.617, respectively. LD values between adjacent marker pairs ranged from 0.135 to 0.194 and from 0.568 to 0.650 for r² for |D′| …

Background: Despite the health concerns and nutritional importance of fatty acids, there is a relative paucity of studies in the literature that report genetic or genomic parameters, especially in the case of sheep populations. To investigate the genetic architecture of fatty acid composition of sheep, we conducted genome-wide association studies (GWAS) and estimated genomic heritabilities for fatty acid profile in Longissimus dorsi muscle of 216 male sheep.

Results: Genomic heritability estimates for fatty acid content ranged from 0.25 to 0.46, indicating that substantial genetic variation exists for the evaluated traits. Therefore, it is possible to alter fatty acid profiles through …

Effect Of Differing Ingredients And Packaging Technologies On The Color Of High-Pressure Processed Ground Beef, Jhinuk Gupta, Chad G. Bower, Gary Sullivan, George A. Cavender

Department of Animal Science: Faculty Publications

High-pressure processing (HPP) is a nonthermal pasteurization technique to control pathogens, like Escherichia coli. However, color changes in raw beef induced by HPP restrict its use within the beef industry. ­e objectives of this study were to investigate the effects of adding curing agents (nitrite) and packaging with or without reducing compounds (ascorbic acid/erythorbate) on color retention in high-pressure processed ground beef. Color was measured (CIE L*a*b*) before HPP and on days 3, 7, 12, 14, 19, and 21 after HPP. Statistical analysis (SAS GLIMMIX) was run to identify the main effects of adding curing agents, packaging, and …

Fecal Microbiota Transplantation Is Associated With Reduced Morbidity And Mortality In Porcine Circovirus Associated Disease, Megan C. Niederwerder, Laura A. Constance, Raymond R. R. Rowland, Waseem Abbas, Samodha C. Fernando, Megan L. Potter, Maureen A. Sheahan, Thomas E. Burkey, Richard A. Hesse, Ada G. Cino-Ozuna

Porcine circovirus associated disease (PCVAD) is a term used to describe the multifactorial disease syndromes caused by porcine circovirus type 2 (PCV-2), which can be reproduced in an experimental setting through the co-infection of pigs with PCV-2 and porcine reproductive and respiratory syndrome virus (PRRSV). The resulting PCVAD-affected pigs represent a subpopulation within the co-infected group. In co-infection studies, the presence of increased microbiome diversity is linked to a reduction in clinical signs. In this study, fecal microbiota transplantation (FMT) was investigated as a means to prevent PCVAD in pigs co-infected with PRRSV and PCV-2d. The sources of the FMT …

Department of Animal Science: Faculty Publications

Methane (CH₄) production of ruminants typically increases with increased dry matter intake (DMI). However, few studies have observed the effects of feeding multiple times a day and its effects on diurnal variation in CH₄ production and energy balance in late-lactation dairy cattle. A study using headbox-style indirect calorimetry and 12 multiparous (225 ± 16.2 d in milk; mean ± SD) lactating Jersey cows was conducted to determine the effects of feeding twice daily on diurnal variation in CH₄ production and total energy balance. A crossover design with 14-d periods (10 d of adaption and 4 d …

Investigation Of The Skeletal Muscle Transcriptome In Lambs Fed Β Adrenergic Agonists And Subjected To Heat Stress For 21 D, Rachel Kubik, Shauna M. Tietze, Ty B. Schmidt, Dustin Tyler Yates, Jessica Lynn Petersen

Department of Animal Science: Faculty Publications

Dietary β-adrenergic agonists (β-AA) are used in livestock to increase muscle protein accretion and decrease adipose deposition during the last 20 to 40 d of the finishing period (Johnson et al., 2014). These β-AA act through specific seven transmembrane receptors and are classified by the receptor isoform to which they primarily bind (Mersmann, 1998). Two β-AA are approved for use in beef cattle in the United States: ractopamine HCl (RAC, β1 agonist) and zilpaterol HCl (ZH, β2 agonist) (Johnson et al., 2014). Supplementation of β-AA increases efficiency of the animal and results in a leaner carcass (Elam et al., 2009). …

Glopl, A Global Data Base On Pollen Limitation Of Plant Reproduction, J. M. Bennett, J. A. Steets, W. Durka, J. C. Vamosi, G. Arceo-Gómez, M. Burd, L. A. Burkle, A. G. Ellis, L. Freitas, J. Li, J. G. Rodger, M. Wolowski, J. Xia, T. L. Ashman, T. M. Knight

Plant reproduction relies on transfer of pollen from anthers to stigmas, and the majority of flowering plants depend on biotic or abiotic agents for this transfer. A key metric for characterizing if pollen receipt is insufficient for reproduction is pollen limitation, which is assessed by pollen supplementation experiments. In a pollen supplementation experiment, fruit or seed production by flowers exposed to natural pollination is compared to that following hand pollination either by pollen supplementation (i.e. manual outcross pollen addition without bagging) or manual outcrossing of bagged flowers, which excludes natural pollination. The GloPL database brings together data from 2969 unique …

Field trials are commonly used to estimate the effects of different factors on crop yields. In the present study, we followed an alternative approach to identify factors that explain field-to-field yield variation, which consisted of farmer survey data, a spatial framework, and multiple statistical procedures. This approach was used to identify management factors with strongest association with on-farm soybean yield variation in the US North Central (NC) region. Field survey data, including yield and management information, were collected over two crop growing seasons (2014 and 2015) from rainfed and irrigated soybean fields (total of 3568 field-year observations). Fields were grouped …

Sculpted From Clay, Shaped By Power: Feminine Narrative And Agency In Wonder Woman, Mikala Carpenter

Master's Theses and Doctoral Dissertations

By applying deconstructive and feminist theories to the Wonder Woman saga, this thesis develops a potential definition of feminine narrative in contrast to the normative and exclusionary patriarchal narrative that reigns supreme in popular culture and Western ideology. Though much of comics discourse functions on the assumption that superhero narratives are homogenous reflections of this ideological hero narrative, I posit that the Amazonian princess's resilience and iconicity stem from her own narrative's uniquely deconstructive nature: Where the patriarchal story would demand dominance, destruction, and violence, the feminine narrative that Diana models advocates for equality, nurturance, and emotional and rational communication. …

Synthesis And Catalytic Testing Of A Proline Functionalized Amphiphilic Block Copolymer, Eric Firestone

Master's Theses and Doctoral Dissertations

Catalysts are reagents used to reduce the amount of energy that a reaction needs to execute, allowing it to proceed at a higher rate while not being consumed. The use of catalyst functionalized amphiphilic copolymer allows easier recovery of the catalyst at the end of the synthesis and allows for the reaction. In water, under appropriate conditions, the amphiphilic block copolymers will form micelles and allow the reaction to occur on the interior of the micelle. The synthesis of amphiphilic copolymer with a hydrophobic O-methacryloyl-trans-4- hydroxy-L-proline and methyl methacrylate end and a hydrophilic acrylic acid end was characterized. The polymer …

Peer Weight Teasing And Body Image In Adolescent Girls: Self-Objectification As A Moderator, Sierra Hill

Senior Honors Theses and Projects

The study expands body image research to examine how weight teasing and self-objectification might be related to body image disturbances among adolescent girls (n=l 00). We conceptualize this relationship using a stress-diathesis model. Through this. a stressful event (e.g., peer weight teasing) would internet preexisting vulnerabilities (e.g., self-objectification) to increase body related distress. We examine the girls' reports of peer weight-teasing, self-objectification, eating attitudes and body dissatisfaction and establish relationships between these variables with a regression analysis. Results indicated that greater self-objectification is related to greater body dissatisfaction. No moderating effect of self-objectification was found for the effect of peer …

Development Of A Gis Database Of Incomplete Forensic Anthropology Cases In Southeastern Michigan, Casey Butler

Senior Honors Theses and Projects

With many forensic anthropology cases of human skeletal remains, the skeletons may be incomplete for a variety of reasons, such as: animal scavenging, acid bone diagenesis, fluvial transport, among other factors. There are many studies that address these taphonomic factors; however, prior research fails to examine different methods in tracking incomplete forensic anthropology cases. This study investigates different geographic information system (GIS) methods applied to the forensic sciences to determine the best software to track forensic anthropology cases using a spatial mapping system to record and track 15 incomplete cases from Southeastern Michigan. The final ArcGIS tool developed here notes …

An Introduction To Feminism And Cross-Cultural Body Image In The United States, Laura Darnell

Senior Honors Theses and Projects

Feminism is a social movement that aims to end the oppression of women and to create opportunities for advancement of women. There are several types of feminism that have their own set of values and beliefs: liberal feminism, radical feminism, cultural feminism, and womanism. Central to these types of feminism is the call for sexism to cease and for women to have equal opportunity. Embedded within modem feminism is intersectionality, which is described as the effect of multiple oppressions that affect women. Misogyny, the hatred of women, affects the way that women feel about themselves. This is done through a …
