Differential Contribution Of Genomic Regions To Marked Genetic Variation And Prediction Of Quantitative Traits In Broiler Chickens, Rostam Abdollaha- Arpanahi, Gota Morota, Bruno D. Valente, Andreas Kranis, Guilherme J. M. Rosa, Daniel Gianola

Department of Animal Science: Faculty Publications

Background: Genome-wide association studies in humans have found enrichment of trait-associated single nucleotide polymorphisms (SNPs) in coding regions of the genome and depletion of these in intergenic regions. However, a recent release of the ENCyclopedia of DNA elements showed that ~80 % of the human genome has a biochemical function. Similar studies on the chicken genome are lacking, thus assessing the relative contribution of its genic and non-genic regions to variation is relevant for biological studies and genetic improvement of chicken populations. Methods: A dataset including 1351 birds that were genotyped with the 600K Affymetrix platform was used. We partitioned …

Effects Of Sorghum Wet Distillers Grains Plus Solubles In Steam-Flaked Corn–Based Finishing Diets On Steer Performance, Carcass Characteristics, And Digestibility Characteristics, E. K. Buttrey, K. H. Noel, F. T. Mccollum Iii, N. A. Cole, L. O. Tedeschi, James C. Macdonald

Department of Animal Science: Faculty Publications

Two studies were conducted to evaluate the effects of sorghum wet distillers grains (SWDGS) in finishing diets on steer performance, carcass characteristics, and nutrient digestibility. In Exp. 1, 240 steers (initial BW = 379 ± 1 kg) were fed steam-flaked corn–based diets with or without 25% SWDGS and 7.5, 10.0, or 12.5% alfalfa hay. There were no effects of alfalfa hay concentration on BW, DMI, ADG, or G:F (P ≥ 0.16). Including SWDGS reduced (P ≤ 0.05) ADG and G:F. Fat thickness decreased (P = 0.03) and DP tended to decrease (P = 0.09) linearly as level of alfalfa hay …

Mesh-Informed Enrichment Analysis And Mesh-Guided Semantic Similarity Among Functional Terms And Gene Products In Chicken, Gota Morota, Timothy M. Beissinger, Francisco Peñagaricano

Department of Animal Science: Faculty Publications

Biomedical vocabularies and ontologies aid in recapitulating biological knowledge. The annotation of gene products is mainly accelerated by Gene Ontology (GO) and more recently by Medical Subject Headings (MeSH). Here we report a suite of MeSH packages for chicken in Bioconductor and illustrate some features of different MeSH-based analyses, including MeSH-informed enrichment analysis and MeSH-guided semantic similarity among terms and gene products, using two lists of chicken genes available in public repositories. The two published data sets that were employed represent (i) differentially expressed genes and (ii) candidate genes under selective sweep or epistatic selection. The comparison of MeSH with …

Extension Demonstration Project Outcomes: Industry Adoption And Translation Of Project Deliverables, Matt Spangler

Department of Animal Science: Faculty Publications

Unfortunately, the amount of feed intake data available to U.S. beef breed associations is spars compared to the amount of data available for growth traits. This makes traditional pedigree-based genetic evaluation for feed intake or efficiency challenging. However, progress in this trait complex could be made as we know that dry matter intake and various “efficiency” traits would respond favorably to selection. Table 1 below depicts the heritability (on the diagonal) and genetic correlations (on the off diagonal) of several feed efficiency traits.

Three experiments evaluated initial implant strategies for finishing cattle. In Exp. 1, heifers (n = 1,405; initial BW = 282 kg) were given (1) Revalor-IH followed by Revalor-200 (REV-IH/200), (2) Revalor-H followed by Revalor-200 (REV-H/200), or (3) Revalor-200 followed by Revalor-200 (REV-200/200). Intake, ADG, and G:F were not affected (P ≥ 0.14) by implant strategies, nor were HCW and LM area (P ≥ 0.16). Percent USDA Choice was greater (P < 0.01) for Rev-IH/200 compared with Rev-H/200 and Rev-200/200. Experiment 2 used steers (n = 1,858; initial BW = 250 kg) given (1) Revalor-IS reimplanted with Revalor-200 (Rev-IS/200), (2) Revalor-XS followed by Revalor-IS (Rev-XS/IS), (3) Revalor-XS followed by Revalor-S (Rev-XS/S), or (4) Revalor-XS followed by Revalor-200 (Rev-XS/200). Implanting strategies did not affect (P ≥ 0.32) DMI or G:F. Carcass traits were not different (P ≥ 0.18) among treatments, except steers implanted with Rev-XS/200 had greater (P < 0.01) LM area. In Exp. 3, steers (n = 1,408; initial BW = 305 kg) were given (1) Rev-IS/200, (2) Rev-200/200, or (3) Rev-XS/200. Gain and G:F did not differ (P ≥ 0.36) among the 3 implant strategies, nor did HCW or marbling score (P ≥ 0.15). Steers given Rev-XS/200 had greater (P < 0.01) LM area and decreased (P ≤ 0.05) 12th-rib fat and YG compared with Rev-200/200 and Rev-IS/200. Using Rev-200/200 and Rev-XS/200 increased (P = 0.03) USDA Select compared with Rev-IS/200. Using greater-initial-dose implant strategies may not affect ADG or G:F but appears to increase leanness.

Paleoindians, Proboscideans, And Phytotoxins: Exploring The Feasibility Of Poison Hunting During The Last Glacial-Interglacial Transition, Alan J. Osborn

Department of Anthropology: Faculty Publications

Archaeologists have long envisioned direct encounters between Paleoindians and megafauna of the Last Glacial-Interglacial Transition (LGIT, 15–11.5 cal BP). Debate continues regarding the role that these Paleoindian hunters played in the extinction event(s). Archaeologists, paleontologists, and paleobiologists have proposed that Paleoindians proved to be very effective hunters who employed darts and spears tipped with razorsharp, chipped-stone projectile points. These weapons are assumed to have been capable of inflicting mortal wounds and death as a result of massive blood loss. Few archaeologists, however, have considered the possible use of hunting poisons, as well as the implications of poison use for past …

A Multi-Scale Spatiotemporal Modeling Approach To Explore Vegetation Dynamics Patterns Under Global Climate Change, Bingwen Qiu, Zhuangzhuang Wang, Zhenghong Tang, Zhe Liu, Difei Lu, Chongcheng Chen, Nan Chen

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Given the complexity of vegetation dynamic patterns under global climate change, multi-scale spatiotemporal explicit models are necessary in order to account for environmental heterogeneity. However, there is no efficient time-series tool to extract, reconstruct and analyze the multi-scale vegetation dynamic patterns under global climate change. To fill this gap, a Multi-Scale Spatio-Temporal Modeling (MSSTM) framework which can incorporate the pixel, scale, and time-specific heterogeneity was proposed. The MSSTM method was defined on proper time-series models for multitemporal components through wavelet transforms. The proposed MSSTM approach was applied to a subtropical mountainous and hilly agro-forestry ecosystem in southeast China using the …

Muts Homolog1 Silencing Mediates Orf220 Substoichiometric Shifting And Causes Male Sterility In Brassica Juncea, Na Zhao, Xinyue Xu, Yashitola Wamboldt, Sally Ann Mackenzie, Xiaodong Yang, Zhongyuan Hu, Jinghua Yang, Mingfang Zhang

Department of Agronomy and Horticulture: Faculty Publications

Cytoplasmic male sterility (CMS) has consistently been associated with the expression of mitochondrial open reading frames (ORFs) that arise from genomic rearrangements. Spontaneous fertility reversion in CMS has been observed in several cases, but a clear understanding of fertility reversion controlled by nuclear genetic influences has been lacking. Here, we identified spontaneous fertile revertant lines for Brassica juncea CMS cytoplasm in which the mitochondrial genome has undergone substoichiometric shifting (SSS) to suppress ORF220 copy number. We placed ORF220, with or without a mitochondrial targeting presequence, under the control of the CaMV35S and AP3 promoters in Arabidopsis to confirm that ORF220 …

Absence Of Mate Choice And Postcopulatory Benefits In A Species With Extreme Sexual Size Dimorphism, Marie-Claire Chelini, Eileen A. Hebets

Eileen Hebets Publications

Most hypotheses related to the evolution of female-biased extreme sexual size dimorphism (SSD) attribute the differences in the size of each sex to selection for reproduction, either through selection for increased female fecundity or selection for male increased mobility and faster development. Very few studies, however, have tested for direct fitness benefits associated with the latter – small male size. Mecaphesa celer is a crab spider with extreme SSD, whose males are less than half the size of females and often weigh 10 times less. Here, we test the hypotheses that larger size in females and smaller size in males …

Phylogeographic And Environmental Dna Analysis Of The Mudpuppy (Necturus Maculosus Maculosus), Amber Stedman

Master's Theses and Doctoral Dissertations

Understanding species’ genetic diversity allows for informed management that preserves evolutionary potential. Informed management becomes crucial as genetic diversity declines and species become susceptible to threats such as climate change. For some species, it can be difficult to determine whether extant populations persist in an area. Genetic tools allow us to address both of these issues. Phylogeographic analyses allow managers to understand a population’s genetic makeup with respect to other populations, facilitating decisions that preserve local adaptation and evolutionary potential. Environmental DNA analysis complements traditional survey techniques and increases confidence when determining species’ range. Here, we explore the phylogeography of …

Satisfaction With Health Information Communication To Multiple Sclerosis Patients, Mariem A. Alrubaie

Master's Theses and Doctoral Dissertations

Multiple sclerosis (MS) is a chronic, unpredictable and crippling neuro-inflammatory disease, affecting an estimated 2.3 million individuals worldwide and 300,000 to 350,000 people in the U.S. MS is the second most costly chronic condition to treat. Given the severity of MS and its impact on patients’ lives, it is important that patients feel engaged in positive, effective communications about the disease. Because of the complexity of the diagnostic process and the patients’ need to adjust to life with MS, patients seek information from as many sources as possible to help them manage health needs. This study sought to investigate MS …
