Investigating How Bat Ectoparasites Influence The Skin Microbiome Diversity And Composition In Washington State Bats, Dana E. Colley
EWU Masters Thesis Collection
White-Nose Syndrome (WNS), caused by the psychrophilic pathogenic fungus Pseudogymnoascus destructans (Pd), has killed millions of bats in the eastern United States since its initial introduction in 2006 and recent expansion into the western U.S. Understanding factors that contribute to the spread of Pd and risk of infection is crucial for management of WNS. Bat ectoparasites, including bat mites and bat flies, are omnipresent in bat populations, yet the relationship between these ectoparasites and bat health is still unknown. We examined the relationship between bat ectoparasites and the skin microbiome in relation to WNS infection risk in Washington State bats. …

Coastal marine habitats continue to be degraded, thereby compelling largescale restoration in many parts of the world. Whether restored habitats function similarly to natural habitats and fully recover lost ecosystem services is unclear. In estuaries, oyster reefs have been degraded by multiple anthropogenic activities including destructive fishing practices and reduced water quality, motivating restoration to maintain oyster fisheries and other ecosystem services, often at relatively high cost. We compared fish and invertebrate communities on recently restored (0–1 year post-restoration), older restored (3–4 years post-restoration), and natural oyster reefs to determine if and when restored reefs support functionally similar faunal communities. …

Kansas Agricultural Experiment Station Research Reports
Some ingredients bind more acid in the stomach than others which can increase gastric pH in weaned pigs, causing decreased protein digestion and allowing pathogenic microorganisms to proliferate. The objective of this experiment was to measure acid-binding capacity at a pH of 4 (ABC-4) of common nursery ingredients and determine additivity in diets. Ingredient categories included: cereal grains, vegetable proteins, animal proteins and milk, vitamin premixes and minerals, amino acids, and fiber sources. A 0.5 g sample of each ingredient was suspended in 50 mL of distilled deionized water and titrated with 0.1 N hydrochloric acid. Sample ABC-4 was calculated …

Kansas Agricultural Experiment Station Research Reports
A total of 21 litters (early or late maturing Duroc × DNA 241) and 247 pigs were used in 170-d trial to determine the effect of sire line growth pattern (early vs. late maturing) and creep feeding on the stress response, intestinal permeability, and growth performance of nursery and finishing pigs.Treatments were arranged in a 2 × 2 factorial with main effect of Duroc sire line (early or late maturing) and lactation creep feeding (with or without). Immediately after weaning (initially 14.0 lb), blood cortisol levels were increased (P < 0.01) in late maturing pigs compared to early maturing pigs, indicating an increased stress response. A greater percentage (P < 0.001) of late maturing pigs lost weight from d 0 to 3 post-weaning compared to early maturing pigs. Likewise, early maturing pigs had improved ADG (P < 0.001) and ADFI (P < 0.001) during the first 3 d in the nursery. A similar response was observed in daily feed intake with early maturing pigs having increased daily feed intake (P < 0.001) for the first 14 d in the nursery. However, no differences were observed in intestinal permeability between treatments. For overall nursery growth performance, a significant interaction was observed for ADG (P = 0.007) and ADFI ( …
