A request to participate was also included in the weekly College of Agricultural Sciences …

Asas-Ssr Triennnial Reproduction Symposium: Looking Back And Moving Forward—How Reproductive Physiology Has Evolved: Fetal Origins Of Impaired Muscle Growth And Metabolic Dysfunction: Lessons From The Heat-Stressed Pregnant Ewe, Dustin T. Yates, Jessica Lynn Petersen, Ty B. Schmidt, Caitlin N. Cadaret, Taylor L. Barnes, Robert J. Posont, Kristin A. Beede

Department of Animal Science: Faculty Publications

Intrauterine growth restriction (IUGR) is the second leading cause of perinatal mortality and predisposes offspring to metabolic disorders at all stages of life. Muscle-centric fetal adaptations reduce growth and yield metabolic parsimony, beneficial for IUGR fetal survival but detrimental to metabolic health after birth. Epidemiological studies have reported that IUGRborn children experience greater prevalence of insulin resistance and obesity, which progresses to diabetes, hypertension, and other metabolic disorders in adulthood that reduce quality of life. Similar adaptive programming in livestock results in decreased birth weights, reduced and inefficient growth, decreased carcass merit, and substantially greater mortality rates prior to maturation. …

Exploration Of Soybean Nodule Microbiome For Plant Health Management, Serkan Tokgöz

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Root nodule is a unique environment formed in the legume roots through a highly specific symbiotic relationship between leguminous plants and nodule inducing bacteria. Over the years, Rhizobia have been thought as the only group of bacteria residing within the nodules. However, this consideration has been recently changed with the discovery of other groups of bacteria besides Rhizobia within the legume nodules. In an effort to identify beneficial bacteria for plant disease control and growth promotion, soybean nodules were studied as the source of nodule-associated bacteria. Metagenomics analysis of a single soybean nodule was conducted to determine the bacterial diversity …

The objective of these 4 studies was to evaluate the effects of management decisions on reproductive performance of beef females. Experiment 1 evaluated the efficacy of a novel s.c. prostaglandin F_2a injection on estrus synchronization and pregnancy success in yearling beef heifers. Heifers receiving a 2 mL s.c. injection of Lutalyse HighCon had similar estrus response and pregnancy rates compared to 5 mL Lutalyse i.m. within 2 different estrus synchronization programs. In experiment 2, May-calving heifers and primiparous cows were allotted to receive either no supplementation or supplement (0.45 or 0.91 kg/d per animal, heifers or primiparous cows, …

Sensitivity Analyses For Simulating Pesticide Impacts On Honey Bee Colonies, A. Carmen Kuan, Gloria Degrandi-Hoffman, Robert J. Curry, Kristina V. Garber, Andrew R. Kanarek, Marcia N. Snyder, Kurt L. Wolfe, S. Thomas Purucker

United States Environmental Protection Agency: Publications

We employ Monte Carlo simulation and sensitivity analysis techniques to describe the population dynamics of pesticide exposure to a honey bee colony using the VarroaPop+Pesticide model. Simulations are performed of hive population trajectories with and without pesticide exposure to determine the effects of weather, queen strength, foraging activity, colony resources, and Varroa populations on colony growth and survival. The daily resolution of the model allows us to conditionally identify sensitivity metrics. Simulations indicate queen strength and forager lifespan are consistent, critical inputs for colony dynamics in both the control and exposed conditions. Adult contact toxicity, application rate and nectar load …

Genetic Diversity And Distinctness Of Wild Nebraska Hops And Hop Cultivars (Humulus Lupulus L.), Megan Franklin

Honors Program: Senior Projects (Public)

Background Commercial hop (Humulus lupulus) cultivars that are being grown in the Midwest are not performing as successfully as when they are grown in the Pacific Northwest, the region to which they are adapted. To increase adaptation to the Midwest environment, one strategy is to draw from the genetic pool of wild native Midwest hops, which have developed genes that allow them to grow successfully in this environment. Wild hop plants that are genetically distinct from commercial cultivars are likely to have more adaptations, such as pest/disease resistance and drought tolerance, which can be bred into commercial lines. The …
