    Three dissertation recitals were performed in partial fulfillment of the requirements for the degree of Doctor of Musical Arts (Music: Performance) in the University of Michigan. The repertoire performed on these recitals represents an offering of the diverse and sometimes eclectic roles of the collaborative pianist. The first recital took place April 7, 2017 at University of Michigan’s Britton Recital Hall. It consisted of Franz Schubert's song cycle, Die schöne Müllerin, featuring tenor, Joshua Lovell. The second recital showcased prominent chamber works in the repertoire for clarinet and piano, and it took place November 11, 2017 at University of Michigan’s Stamps Auditorium. The recital featured clarinetist, Joshua Anderson, and cellist, Richard Narroway. The program consisted of Para Fred, a suite of transcribed Spanish songs arranged by Martin Katz; 4 Stücke, op. 5 by Alban Berg; Grooves, by Philip Parker; and Alexander von Zemlinsky's Trio for clarinet, cello, and piano, op. 3. The third dissertation recital was a lecture recital presented April 18, 2018 at the Faber Piano Institute in Ann Arbor, Michigan. The lecture focused on ways in which different composers set the same poems in song, and featured soprano, Madeline Thibault, and baritone, Samuel Kidd.AMUMusic: PerformanceUniversity of Michigan, Horace H.

    Effects of Heat Stress on Ovarian Physiology in Growing Pigs

    Ovaries were obtained from growing pigs that had been heat-stressed and were evaluated for alterations in a signaling pathway known to play a critical role in ovarian physiology. Our results indicate that hyperthermia alters this pathway in a short space of time (after 7 days). Identifying how and why heat stress alters ovarian physiology are important in developing therapeutic approaches to prevent the reduction in reproductive performance associated with warm summer months

    Does Heat Stress Alter the Pig’s Response to Dietary Fat Source, as it Relates to Apparent or True Total Track Digestibility?

    Heat stress affects a plethora of pork production variables, in part stemming from a reduction of feed intake. The experimental objective was to investigate the effect of heat stress on the pig’s response to dietary fat in terms of growth performance and digestibility over a 35 d finishing period. A total of 96 barrows were randomly allotted to 1 of 9 treatments arranged as a 3 × 3 factorial with the main effects of environment [thermonetural (TN), pair-fed thermoneutral (PFTN), or heat stress (HS)] and diet [a corn-soybean meal based diet with 0% added fat (CNTR), or the CNTRL with 3% added tallow (3%TAL), or 3% added corn oil (3%CO)]. Pigs were individually housed to record intake. Fecal samples were collected on d 17 (~ 114 kg). No significant interactions between environment and diet were observed (P \u3e 0.100). HS decreased ADFI (27.8%; P\u3c 0.001), ADG (HS = 0.72, TN = 1.03, PFTN = 0.78 kg/d; P \u3c 0.001), and G:F (HS = 0.290, TN = 0.301, PFTN = 0.319; P = 0.006). G:F but not ADG or ADFI tended to increase with added fat (CNTR = 0.292, 3%TAL = 0.303, 3%CO = 0.314 g/100 g; P ≤ 0.073). Environment had no impact of TTTD of AEE (P = 0.118). In summary, HS decreased ADFI, ADG, G:F and ATTD of AEE, but had no significant impact on TTTD of AEE. Therefore, the pig’s response to dietary fat source is not different in heat stress conditions as compared to thermoneutral conditions

    Effects of Heat Stress and Plane of Nutrition on Production and Metabolism in Growing Pigs

    We heat-stressed growing pigs and evaluated the differential effects of environmental hyperthermia and reduced feed intake. Our results indicate that hyperthermia directly effects production and metabolism and many of these are independent of reduced nutrient intake. Identifying how and why heat stress alters metabolism and physiology are prerequisites in developing ameliorating strategies to prevent the reduction in performance and lost income typically observed during the warm summer months

    Heat stress adaptations in pigs

    Implications • Heat stress is a global issue constraining animal agriculture productivity, negatively affects welfare, and reduces production efficiency in many countries. • The effects of heat stress on pig production will intensify, if climate change continues as predicted. • To date, modifying the environment is the most effective way to mitigate the effects of heat stress. • Identifying additional strategies (nutritional and genetics) to maximize pork production during the warm summer months is necessary to satiate a growing demand for high quality meat for human consumption

    Climate Dependent Heat Stress Mitigation Modeling for Dairy Cattle Housing

    Dairy cattle are susceptible to heat stress with reported milk production loss exceeding 1.2 billion dollars in 2010. Heat stress occurs when the local thermal environment prevents adequate dissipation of metabolic heat production over extended periods. Implementing mitigation strategies in order to reduce heat stress has been a crucial need as dairy housing has transitioned from pasture to indoor housing systems. In order to maximize production, producers need the most effective cooling system to reduce heat stress. A heat stress mitigation model was developed using TMY3 data sets as inputs. The objectives of this research were to: (i) analyze the thermal environment’s ability to reduce heat stress in dairy cattle in selected regions using TMY3 data, (ii) model Holstein cattle subjected to various environmental modification systems (elevated airspeed, evaporative pad cooling, direct sprinkling) by region, (iii) create a universal barn/cooling system model to apply to selected regions with given TMY3 data inputs, and (iv) develop contour maps with optimal cooling system recommendations throughout the United States. A transient thermal balance model was developed using equations and parameters from published heat stress models in order to quantify heat dissipation from a dairy cow to her environment. The model was initially tested and evaluated using two TMY3 stations (Fresno, California SN:723890 and Eau Claire, Wisconsin SN:726435). The model’s predictions were within one standard deviation of field data. Once validated, the model was applied to all 215 TMY3 Class 1 stations and contour maps of the U.S. were created for producers to determine which cooling strategy is the most economical in their region
