AnSci Connection - April 2018
Notes from the Department Head
It is important to acknowledge achievements, and April has been a time of celebration and recognition in our department. Earlier this month, we held our second annual Animal Science Showcase and honored two Golden Alumni Award winners, Drs. Bruce Behrends and Bradley Johnson, for their outstanding contributions to animal agriculture. It was a wonderful event that showcased our faculty, students and alumni and allowed us to connect with numerous stakeholders. At this event, it was also announced that the newly formed Animal Science Diversity Committee would honor Dr. Sally Noll as the first female faculty member hired and tenured in our Department. Our department will celebrate Dr. Noll by naming the 4th floor Haecker Hall conference room in her honor. (Date and time to be announced in the May issue of the AnSci Connection.) Finally, we are proud to share some of our department’s metrics tied to teaching, research and Extension. In 2017, our department was home to 29 faculty, 49 graduate students, and 421 undergraduate students. Our teaching faculty maintained excellence in our animal science core courses while expanding offerings to include 5 online and 3 study abroad courses. Last year 759 students enrolled in our online courses, many from majors other than Animal Science. Our faculty secured over $3 million in grants, gifts, and royalties; published over 100 abstracts and proceedings; gave 132 invited presentations; and published 77 manuscripts. To disseminate our research results and connect with livestock owners and industry professionals, our Extension faculty published 59 Extension articles and led 58 Extension programs. Thank you to our faculty, students, staff, and stakeholders for their collective efforts in making these impacts!
April has also been a month of extreme weather with the potential to negatively impact livestock health and shorten the growing season. Many of our faculty help maintain websites that offer resources for livestock owners, including beef cattle, dairy cattle, horses, poultry, swine, and farms with small acreage. However, we know spring will eventually arrive and our thoughts turn towards safety around spring farm activities, especially as the timeline to accomplish these activities become condensed. UMASH (Upper Midwest Agricultural Safety and Health Center) is a great site for livestock owners with many resources aimed at agriculture health and safety. I wish everyone a safe, productive and warm spring.

Teaching, Research, and Extension Highlights
As printed in the University of Minnesota: Research Brief
While aging is familiar to all of us, exactly how it occurs on a molecular basis has been an area of intense study and interest. We take it for granted that different species age at different rates, yet we do not have a good understanding of why and how. Most mammals have similar numbers of genes, many of which show conserved function, yet there are several orders of magnitude differences in lifespan across mammals. For instance, mice and small animals live shorter lifespans, yet other animals such as bats, naked mole rats, whales, elephants and primates age significantly slower.
What is different in the genomes of these species that allows them to live so long? It is only with the advent of full genomes for hundreds of species that we can begin to compare lifespans between species with differences in their genomes.
Research led by University of Minnesota, Department of Animal Science Assistant Professor Christopher Faulk reveals that regions that control gene expression have evolved to contain more epigenetic switches in about 5 percent of our genes. These switches control the amount of protein made by these genes, rather than the type of protein, and may be able to prevent these protein levels from changing in animals that have longer lifespans.
His study, "The Evolution of CpG Density and Lifespan in Conserved Primate and mammalian Promoters," published in the April issue of Aging, found that 5 percent of our genes have a previously undiscovered link to lifespan. By comparing the epigenetic control regions, called promoters, in 25,000 genes in more than 100 animal genomes, his team detected a signal identifying these genes as under evolutionary selection for long lifespan.
Most gene promoters are enriched in CpG dinucleotides, a letter C next to a letter G in the DNA code, as measured by the density of CpG sites in a region. The trait of CpG density in promoters does not change the gene sequence itself, but controls how much of the gene product is made. However, the number of CpG sites in a specific gene promoter region can differ between species.
“In the majority of the genes we identified, we found a positive correlation between increasing CpG enrichment and lifespan,” Faulk said. “We believe these genes evolved to allow greater control over protein production as an animal ages.”
The study used data from the National Center for Biotechnology Information and the Eukaryotic Promoter Database to download more than 100 mammalian genomes and identify corresponding promoter regions that are shared between humans and these mammals.
“This research is only possible now that hundreds of genomes are in the public domain,” Faulk explained. “This represents tens of billions of dollars in research funding for hundreds of separate groups working on their own goals. We were able to leverage this freely available data in a new way to answer a question about the evolution of the epigenome. And even more, this research uses the differences in species acquired over millions of years to tell us something about how aging and lifespan have evolved. Almost everyone will get old and die and that is generally considered to be a bad health outcome.”
A more comprehensive comparison of data needs to happen next. “This project really provides the first analysis using massive comparative genomics to give understanding to a physiological trait like aging. We were unsure of whether anything would be found, and surprised at the strength of the signal. The next steps will involve more comprehensive comparison of other genomic regions, generating a better comparative database, and comparing other life history traits to genomic features. We must confirm the function of these regions in a lab model,” Faulk said.
This work was supported by the NIH National Institute of Environmental Health Sciences, as well as the SUNY Polytechnic Institute Research Foundation.

As a person with Asperger’s Syndrome, a form of Autism, Mariah has dependably worked four semesters at the University of Minnesota’s Poultry Research Barn and Lab Facility where her role includes sample collection, bird care, processing, recordkeeping and data computation for turkey nutritional feed analysis study and production studies. Recognized as the “Ducks in a Row” award recipient in the 2017 Midwest Poultry Consortium’s (MPC) Summer of Excellence program. She is applying to the University of Minnesota’s Animal Science Graduate Program with a production emphasis focus for the fall of 2018.
Grant Hedblom’s four years as an undergraduate at the University of Minnesota and two years at 3M helped him recognize that his passion lies in understanding microbes and how they affect the global food supply. This fall, he entered his graduate career at the University of Minnesota ready toutilize his insights, passion, and knowledge to make a difference in the study and education of food microbiology. In 2013 Grant completed a summer research internship at the Center for Infectious Disease Research and Policy (CIDRAP), working under world-wide expert in epidemiology, Dr. Michael Osterholm, where he assisted in the publication of articles and updates regarding emerging public health threats and infectious diseases. His first hands-on research experience was in the research laboratories at 3M. Grant was hired as a technical aide in a laboratory dedicated to the development of a chemical formulation for the generation of an anaerobic growth environment for the easy cultivation of anaerobic bacteria. This project received 3M’s Circle of Technical Excellence & Innovation award – signifying it as one of the top 5 research projects across the entire company in 2014. After graduating from the University of Minnesota, Grant was fortunate to continue his work at 3M on the anaerobic atmosphere project, which had been moved to the Food Safety Division of 3M for scale-up and development as a 3M TM PetriFilmTM Lactic Acid Bacteria Count Plates for use in lactic acid bacteria enumeration and detection. In the fall of 2016, he began his PhD studies at the University of Minnesota – Twin Cities in the laboratory of Dr. David Baumler where he has been utilizing genome-scale metabolic models to understand the nutrient utilization of Listeria monocytogenes to better understand how this major threat to food safety proliferates and develops in foods. These computational simulations will predict gene and metabolite usage for growth in foods that are notorious for L. monocytogenes contamination, such as soft cheeses, dairy products, and ready-to-eat deli meats. This type of modeling has been performed for other foodborne pathogens such as Salmonella, and Escherichia coli O157:H7, and will be the first of their kind for L. monocytogenes. After obtaining his doctorate, Grant plans to work in the food industry to develop new detection methods for bacteria and other microorganisms in foods.
The annual recognition banquet of the Gopher Dairy Club was held Sunday, February 25, in the ballroom of the Radisson Roseville. About 200 students, parents, faculty, and industry representatives were in attendance. President Laura Jensen, Comstock, WI, served as emcee. CFANS Dean Brian Buhr welcomed those in attendance, and Princess Kay Emily Annexstad provided remarks. The keynote speaker was Sheryl Meshke, Co-CEO of AMPI, New Ulm, MN.
The club's Golden Graduate Award was presented to Mr. Brad Rugg, MN 4-H Animal Science Program Director, and David and Donna Anderson, Guernsey breeders from Lester Prairie, MN, received the club's Distinguished Service Award. New members of the club in 2017 received scholarships, including Katie Thompson, Plainview, MN, who received the Douglas Siem $2,000 Memorial Award as the highest ranking applicant for the new student scholarships.
Morgan Krause, Buffalo, MN, was announced as the R. W. Touchberry Outstanding Junior in Animal Science. The club recognized Gabriella Sorg, Hastings, MN, as its Outstanding Senior and Rachel Coyne, Spring Valley, WI, as its Outstanding Rookie (sophomore). Also, Laura Jensen and Gabriella Sorg were announced as the club's two nominees for National Dairy Shrine's Senior Student Recognition Program. The banquet program concluded with a slide show from the club's senior trip to California, which took place from January 6 to 15.
University of Minnesota students participated in the 17th Annual North American Intercollegiate Dairy Challenge® (NAIDC) held April 12-14 in Visalia, CA. In total, 235 students from 38 colleges across the U.S. and Canada attended this educational event.
The national contest team consisted of Ethan Dado, Laura Jensen, Blaine Knutson, and Austin Schmitt. The students represented the University of Minnesota well and gave highly rated presentations. Six students participated in the Dairy Challenge® Academy: Anne Benzine, Amber Cafferty, Lauren Hendel, Krista Styer, and Jake Siewert. The NAIDC teams are coached by Dr. Marcia Endres.
Dairy Challenge® is an innovative three-day competition and learning opportunity (Academy) for students representing dairy science programs at North American universities. It enables students to apply theory and learning to a real-world dairy, while working as part of a team. In its 17-year history, Dairy Challenge has helped train more than 6,400 students through the national contest, Dairy Challenge Academy and four regional contests conducted annually.
Collegiate participants visited six dairy farms in California, as part of their training to help farmers evaluate and adapt management to optimize success and animal care. Also, industry professionals presented cutting-edge research, new programs and career opportunities to students.
Each contest team received information from an area dairy, including production and farm management data. After an in-person inspection of the dairy, students interviewed the herd owners. Each team developed a farm analysis and recommendations for nutrition, reproduction, milking procedures, animal health, housing and financial management.
The event culminated with team members presenting recommendations and then fielding questions from a panel of judges. These official judges included dairy producers and industry experts in dairy finances, reproduction, nutrition and animal health. Presentations were evaluated for accuracy of analysis and recommendations, with awards presented at a final banquet.
The Dairy Challenge Academy was developed in 2013 to expand this educational and networking event to more college students. Academy student-participants also analyzed and developed recommendations for an operating dairy; however, the Academy was organized in mixed-university teams with two Advisors to help coach these younger students.

In early February, Dr. Pedro Urriola presented at Pig Ski 2018. This conference gathers approximately 80 pork producers and service companies (e.g., financial services, genetics, pharmaceutical, feed additives) under the motto of learning, family, and fun. Pedro shared the work happening at the University of Minnesota with distillers’ coproducts such as prediction of energy, amino acid digestibility, dietary fiber, etc. He also talked about the Integrated Animal Systems Biology group, sustainable pork production, and management of food waste.
During his time at Pig Ski, Pedro learned about two companies developing new ways to raise and sell pork in innovative ways. These companies are rapidly adjusting their business models to global and United States market forces. Clemens Food Group is vertically integrated from production, harvest, distribution and recently opened a new processing plant in Coldwater, MI. New Fashion Pork is located in Jackson, MN; they partnered to build a new plant for Triumph Foods in Sioux City, IA. The capacity for processing pork in the United States has increased to accommodate for global demand. At the same time, consumers are requesting pork (poultry as well) that are raised under specific conditions such as antibiotic-free livestock production and transparency to the consumer in terms of animal care and production systems. Clemens has adjusted their model to create the Farm Promise brand that promises No Antibiotics Ever (NAE). New Fashion Pork has partnered with the Global Animal Partnership, a nonprofit focused on improving farm animal welfare, to build and design a new sow barn in Thorp, WI. The results of these enterprises and their impact on how we raise and feed pigs is yet to be determined.

Graduate Student Spotlights
Anna is originally from Huntington Beach, California. She moved to the Midwest in the fall of 2011 to attend Iowa State University to obtain a bachelors in Animal Science. At Iowa State she worked in a swine nutritional physiology lab that encouraged her to go into swine nutrition (especially being from the concrete jungle that is Southern California). After graduation Anna moved up to Minnesota with her then fiancé to take a position at a small animal feed additive company focusing on feeding natural alternatives. After 1 1/2 years of working full-time and getting married, she went down to part-time in to be able to attend school full-time to obtain her master’s degree in Animal Science. Currently, Anna is keeping herself very busy with her on-going trial for her thesis. Her research focuses on fetal programming, supplementing mouse dams with a metabolite of leucine to reduce within-litter birth weight variation. If successful, Anna and her advisors hope to translate this into the swine industry. She plans to defend in fall 2018 and return to industry afterwards. In her free time she enjoys spending time with her husband and their dog and going to all types of Minnesota sporting events.
Congratulations to Katie Cottingim (M.S.) on passing her final exam! Katie was advised by Dr. Sam Baidoo.
