Vaccination Against Lawsonia intracellularis Decreases Shedding of Salmonella enterica serovar Typhimurium in Co-Infected Pigs and Alters the Gut Microbiome

    *Salmonella enterica* is a leading cause of foodborne illness worldwide and pork can serve a source of infection. In this study, we investigated if vaccinating pigs against L*awsonia intracellularis*, a common pathogen of swine that has previously been shown to favor *Salmonella enterica* infection, confers protection against *Salmonella enterica serovar Typhimurium*. We investigated the underlying changes in the gut microbiome mediated by single *S. Typhiumurium* infection compared to co-infection with *L. intracellularis* as well as the effect of vaccination on the microbiome.

    Organic Beef Data from Integration of Crops and Livestock Project

      As the organic forage-finished beef industry continues to grow, it is important to understand factors that affect meat quality, characteristics of beef that influence human health, and sensory attributes of cooked beef. Research on alternative breeds and forage types that influence meat quality, FA and AA profiles, and sensory attributes in an organic forage-finished production system, as well as comparisons with alternative breeds is lacking. Data release is part of data management plan with USDA-NIFA funding. Data is from organic dairy beef steers collected at the West Central Research and Outreach Center, Morris, MN.

      Environmental Association Analyses Identify Candidates for Abiotic Stress Tolerance in Glycine soja, the Wild Progenitor of Cultivated Soybeans

        The present study explores an ex situ conservation collection, the USDA germplasm collection, genotyped at 32,416 SNPs, to identify population structure and test for associations with bioclimatic and biophysical variables in Glycine soja, the wild progenitor of Glycine max (soybean). Candidate loci were detected that putatively contribute to adaptation to abiotic stresses.

        Restoration of the 1936 Statewide Forest Survey of Minnesota

          Over 300 stand and stock tables and summary of volume tables for Minnesota were restored from the first FIA Lake States forest survey conducted between 1930 and 1938. The level of detail of the data varied, but included area of forest cover types and stand size classes, and number of trees and volumes per acre by individual species. The data was presented in an Access database with a series of tables and queries. Definitions and further explanations about the restored historic data can be found in Staff Paper Series No. 241, Department of Forest Resources, University of Minnesota.

          Risk prioritization of pork supply movements during an FMD outbreak in the US - Data and Materials

            This study recruited experts from production, harvest, retail, and allied pork industries to assess 30 common pork supply movements for their industry criticality. Movements spanned five categories: equipment, live animal production, genetics, harvest, and people. Experts were recruited via email to the American Association of Swine Veterinarians (AASV) mailing list and their assessments were collected via an online survey. The Data.csv file contains the raw survey responses.

            Effort Versus Reward: Preparing samples for fungal community characterization in high-throughput sequencing surveys of soils

              This data set consists of four data files. The FASTA file, Representative OTU sequences.fa, contains representative sequences from the operational taxonomic units (OTUs) shown in the OTU table. FASTA files can be opened in simple text editors, and sequences can be aligned using the BLAST tool (http://blast.ncbi.nlm.nih.gov/Blast.cgi) or open source software, like AliView (http://www.ormbunkar.se/aliview/). There are two Excel data files: OTU table and heatmaps.xlsx and Diversity Indexes.xlsx. The former contains the raw abundance data for the observed OTUs from the different experimental sites. The latter is a breakdown of various diversity indices that are grouped based on experimental characteristics, such as extraction volume, extraction method, etc. Excel_Archive.zip is a compressed version of the two Excel data files that have been converted to more archival-friendly formats using Excel Archival Tool.

              Sustainable Corn CAP Research Data (USDA-NIFA Award No. 2011-68002-30190)

                The Sustainable Corn CAP (Cropping Systems Coordinated Agricultural Project: Climate Change, Mitigation, and Adaptation in Corn-based Cropping Systems) was a multi-state transdisciplinary project supported by the USDA National Institute of Food and Agriculture (Award No. 2011-68002-30190). Research experiments were located through the U.S. Corn Belt and examined farm-level adaptation practices for corn-based cropping systems to current and predicted impacts of climate change.
