Porcine circovirus 2 (PCV2) is a circular single-stranded DNA virus responsible for a group of diseases collectively known as PCV2 Associated Diseases (PCVAD). Variation in the incidence and severity of PCVAD exists between pigs suggesting a host genetic component involved in pathogenesis. A large-scale genome-wide association study of experimentally infected pigs (n = 974), provided evidence of a host genetic role in PCV2 viremia, immune response and growth during challenge. Host genotype explained 64% of the phenotypic variation for overall viral load, with two major Quantitative Trait Loci (QTL) identified on chromosome 7 (SSC7) near the swine leukocyte antigen complex …

Research Note Prediction Model For Manure Zinc Excretion In Laying Hens, Kelli M. Martin, N. Vargas-Jurado, S. E. Purdum

Department of Animal Science: Faculty Publications

The objective of this research trial was to compare 2 sources of zinc and different levels of supplementation on manure zinc excretion in laying hens. Bovan White Leghorn hens were used in this study and fed one of 6 dietary treatments. Treatments were in a 2 × 3 factorial arrangement with 2 sources of zinc (zinc sulfate or Availa R < Zn) and 3 levels (40, 80, or 120 ppm) and were randomly assigned to 48 cages with 5 hens/cage and 8 replicates/treatment. Hens were housed in a tiered manure-belt housing system providing 627.1 cm2/hen and were given access to 110 g/hen/d of feed. Manure samples were collected, and manure zinc content was calculated at 10- week intervals. Data were analyzed using the Glimmix procedure in SAS. There was a significant overall effect of source (P < 0.0001) for zinc content, such that hens fed zinc sulfate had lower amounts of zinc excretion. There was also a significant level effect (P < 0.0001) in which hens fed 120 ppm zinc excreted the greatest amount of zinc. A significant source by level interaction was observed (P < 0.0001) for both the overall and individual analyses, such that 120 ppm Availa R < Zn showed the highest zinc excretion, and both 40 ppm zinc sulfate and Availa R < Zn showed the lowest zinc excretion. Based on these results, a prediction equation was written for an estimated amount of zinc excretion based on the amount of zinc provided in the diet.

Ecological And Indigenous Community Impacts Of Oil Spill Mortality In Alaskan Marine Ecosystems, Paul M. Suprenand, Carie Hoover, Cameron H. Ainsworth, L. Dornberger, C. J. Johnson Jan 2018

Ecological And Indigenous Community Impacts Of Oil Spill Mortality In Alaskan Marine Ecosystems, Paul M. Suprenand, Carie Hoover, Cameron H. Ainsworth, L. Dornberger, C. J. Johnson

Marine Science Faculty Publications

While hydrocarbon exploration and extraction in the Arctic ebbs and flows, reduced sea ice has opened new travel routes across the Arctic. The opening of the Northwest Passage has allowed larger ships (including oil tankers) and higher traffic into remote regions. More ice loss is expected in the future. With this comes the potential for hydrocarbon spills. To quantify the ecosystem impacts of a spill in the Alaska North Slope region, an Ecospace model using the Ecopath with Ecosim software was developed. We highlight the impacts of four potential hydrocarbon contamination scenarios: a subsurface crude oil pipeline release, a surface …

Tripartite Interactions Of Legumes With Arbuscular Mycorrhizal Fungi And Rhizobial Bacteria: Insight Into Plant Growth, Seed Yield, And Resource Exchange, Arjun Kafle

Electronic Theses and Dissertations

Under natural conditions, legumes, such as alfalfa (Medicago) and soybean (Glycine max) are colonized with arbuscular mycorrhizal (AM) fungi and rhizobial bacteria forming tripartite interactions. Legumes are important crop species due to their high nutritional and economic values. Most of the previous literatures focused on experiments with an individual symbiont: either AM fungi or rhizobial bacteria, but not with both symbionts at the same time, thus our current understanding of resource exchange in tripartite interactions is limited. It has been reported that AM fungi primarily provide phosphate (P), nitrogen (N), and other nutritional and non-nutritional benefits while rhizobial bacteria solely …

Diversity Of Free – Living Nitrogen – Fixing Bacteria In Soil Of Sioux Prairie Of South Dakota, Nabilah Ali Alshibli Jan 2018

Diversity Of Free – Living Nitrogen – Fixing Bacteria In Soil Of Sioux Prairie Of South Dakota, Nabilah Ali Alshibli

Electronic Theses and Dissertations

There are only two natural ways by which molecular nitrogen can be available to support life, either by free-living or by symbiotic nitrogen fixing bacteria. The best studied diazotrophs form symbiotic associations with plants, primarily legumes and certain tree species, but little is known about how non-leguminous plants such as grasses obtain nitrogen in their environment. Natural prairies have few legumes, thus have less symbiotic nitrogen fixer interaction. This indicates presence of free-living nitrogen (FLN) fixation activity towards the balance of the N cycle. The objective of this study was to characterize the culturable diversity of free-living diazotrophs in native …

Genetic Component Effects Of Two Loci On Seed Dormancy, Awn, Low-Temperature Germination, Plant Height, And Flowering Time In Rice (Oryza Sativa L.), Ugur Korkmaz

Electronic Theses and Dissertations

Seed dormancy (SD) is an adaptive trait of both ecological and agricultural importance. Cereal crops have been selected for reduced SD to promote germination, which also caused the pre-harvest sprouting (PHS) problem in crop production. The previous research identified a set of quantitative trait loci (QTL) for SD, including qSD1- 2 and qSD8, in the conspecific weedy and cultivated rice (Oryza sativa). qSD1-2 carries a dormancy-enhancing allele from the cultivated rice and has a pleiotropic effect on plant height. qSD8 carries a dormancy-enhancing allele from the weedy rice and tightly links to qAL8 for awn length. The …
