For more than 125 years, Virginia Tech has helped advance animal agriculture through education, research, and Extension. That legacy reached a major milestone with the creation of the School of Animal Sciences, bringing together two nationally recognized departments to form the largest animal sciences program east of the Mississippi. The new school builds on a long tradition of hands-on learning, research, and service to Virginia’s agricultural communities while creating new opportunities for students, faculty, and industry partners. Bringing these programs together also creates stronger connections across disciplines, from livestock and dairy science to companion animals and biomedical research. For students, it means more ways to learn across programs, work alongside faculty, and gain experience with animals both in and beyond the classroom.

Dear Alumni and Friends,

Welcome to another exciting year in the School of Animal Sciences! It’s a pleasure to reconnect with you through this inaugural edition of the School of Animal Sciences newsletter.

Our classrooms, laboratories, farms, and teaching facilities are once again filled with students eager to begin another year at Virginia Tech. This fall, we are delighted to welcome 219 new undergraduate students, bringing total undergraduate enrollment to 733 students, the largest enrollment in the School's history. This remarkable growth reflects both the increasing demand for careers involving animals and the outstanding reputation our faculty, staff, students, and alumni have built together.

That reputation extends well beyond Blacksburg. Today, the School of Animal Sciences ranks among the nation's premier animal science programs. Recent national benchmarking places Virginia Tech among the very top academic units in the country in federally funded research, ranking 2nd nationally in total federal grants, 3rd in total federal research funding, and among the leaders in grant-active faculty. These accomplishments reflect the creativity of our faculty and the confidence that federal agencies and industry partners place in the work being conducted here. They also demonstrate that Virginia Tech is helping define the future of animal agriculture while increasingly contributing to advances in human health through One Health and translational biomedical research.

Of course, our greatest strength continues to be our students. Whether they aspire to careers in veterinary medicine, livestock production, companion animal science, research, industry, or graduate education, our faculty are committed to providing an educational experience grounded in hands-on learning. From research laboratories and livestock farms to internships, judging teams, undergraduate research, and Extension programming, students have opportunities to develop the knowledge, leadership, and practical skills that distinguish Virginia Tech graduates.

Our faculty also continue to address some of society's most pressing challenges. Research programs span sustainable livestock production, precision nutrition, animal welfare, reproductive biology, data science, neuroscience, and biomedical discovery using large animal models. At the same time, our Extension faculty remain deeply engaged with producers, veterinarians, youth organizations, and commodity groups across the commonwealth, ensuring that new discoveries quickly become practical solutions for Virginia agriculture.

As we look toward the future, we continue to build on an ambitious vision for the School. We are expanding our companion animal and equine programs, rebuilding key areas such as poultry science, strengthening interdisciplinary collaborations across campus, and modernizing research and teaching facilities. Our long-term goal is clear: to become one of the nation's premier schools of animal sciences while remaining the trusted source of education, discovery, and outreach for Virginia's animal industries.

None of these accomplishments would be possible without the support of our alumni and friends. Your mentorship, philanthropy, advocacy, and engagement continue to shape the experiences of our students and strengthen the future of our School. Thank you for remaining an important part of the Virginia Tech Animal Sciences family.

This special retrospective issue highlights some of the people, programs, discoveries, and milestones that have shaped the School of Animal Sciences. While no single publication can capture every accomplishment, we hope these pages reflect the innovation, dedication, and Ut Prosim spirit of our community. I hope you enjoy this edition of our newsletter and look forward to seeing many of you on campus during the coming year.

Go Hokies!

Livestock Judging Team returns to national competition

After more than a decade, Virginia Tech once again fielded a full Livestock Judging Team, marking the return of the program to national competition. Since 2024, students have competed at premier events including the National Western Stock Show and Rodeo, North American International Livestock Exposition, Southeastern Regional, All East, Keystone International, and other regional contests.

Participation has grown rapidly — from 10 students in 2024 to more than 30 in 2025 — and the program celebrated its first Top Judge graduate, Salem Sifford.

Team members continue to cite livestock judging as their most impactful experiential learning experience, with recent graduates finding success in graduate school, feedlot management, agricultural lending, vet school, ag business management, and agricultural education.

Beef Extension Update

Beef Cattle University (BCU) continues to grow
The beef business has witnessed record prices over the past couple of years, and Virginia’s cow-calf producers have been the beneficiary of this. Enthusiasm and interest were on display at the recent Beef Cattle University hosted July 8-10 on campus. This is the third year for BCU, which is a joint effort between Virginia Cooperative Extension and the Virginia Cattlemen’s Association with support from numerous industry sponsors. The event attracted around 300 participants to Blacksburg for a two-day program which featured nationally renowned keynote speakers, as well as numerous breakout sessions focusing on timely topics. Details of the event, including speakers’ notes and resources, can be found at https://vabeefcattleu.com.

Helping producers respond to drought
Producers across Virginia and throughout the region are evaluating strategies to cope with drought. The key difference in 2026 is that the drought was initiated in the spring and has continued into the more traditional drought period of mid- to late summer. Also, this is a continuation of drought conditions that started last fall and even prior. The timing, severity, length, and widespread nature of this drought make for different considerations than usual drought mitigation strategies. The Extension team has hosted several webinars and developed resources and recommendations for producers to deal with drought. Please visit the Virginia Tech Beef Extension website for recordings of these webinars: https://sas.vt.edu/extension/vtbeef.html#emergency-drought.

Record year for the Virginia BCIA bull sales
The Virginia Beef Cattle Improvement Association in collaboration with Virginia Cooperative Extension completed its 68th year of developing and marketing bulls through the state central bull test program. The 2025-26 test and sale year proved to be one for the record books! The program included the development of 399 total bulls, with 223 bulls selling through two sales for an average price of $7,515, which is the highest average price on record for Virginia BCIA. This average price compares to $6,124 in 2024-25, $4,902 in 2023-24, and $3,742 during 2022-23. Of the 223 bulls sold, 175 (78%) were purchased by Virginia buyers and 48 (22%) sold out of state to cattlemen in Kentucky, Maryland, North Carolina, Oklahoma, Pennsylvania, Tennessee, Texas, West Virginia, and Canada. For a more detailed summary of this information, or details for the upcoming 2026-27 Virginia BCIA Central Bull Test Station program, visit https://virginiabcia.com/.

Dairy Extension Update

Meeting the challenges ahead
The Virginia Tech Dairy Extension program in the School of Animal Sciences is led by Dr. Gonzalo Ferreira, Dave Winston, and Dr. Christina Petersson-Wolfe. Together, our mission is to provide timely, science-based education, research, and technical support to dairy producers and industry stakeholders while addressing the evolving needs of Virginia's dairy industry. Over the next several years, the industry will face significant challenges driven by labor shortages, rising production costs, market volatility, emerging animal health threats, increasing pressure to reduce antimicrobial use, and growing environmental and sustainability expectations. Producers must also adapt to rapidly advancing technologies, including automation, artificial intelligence, and precision livestock tools, while managing increasing amounts of data to support informed decision-making. In addition, changing consumer expectations regarding animal welfare, transparency, and sustainable production, coupled with climate-related challenges and continued industry consolidation, will require dairy operations to become more efficient, resilient, and innovative. Navigating these challenges will require practical, science-based solutions that help Virginia dairy producers improve productivity and animal health while strengthening environmental stewardship and long-term profitability.

Research-based forage management
Dr. Ferreira's Extension program focuses on improving producers' understanding and interpretation of forage analysis through applied research and outreach. In collaboration with Virginia Cooperative Extension Agriculture and Natural Resources agents, his team is organizing a field day at Kentland Farm on September 15, 2026, where current research on small grain grasses and alfalfa production and management will be presented. His program continues to deliver research-based information through Extension publications and articles in Hoard's Dairyman and Hay & Forage Grower, translating scientific findings into practical management recommendations for producers.

Using data to strengthen herd management
Dave Winston's Extension responsibilities center on dairy information systems, including DHIA records, herd management software, and data management to support on-farm decision-making. He also provides educational programming in calf and heifer management and works closely with the Youth Animal Science Team to support dairy youth events and leadership development. In addition to his Extension activities, he also brings that expertise into the classroom, where students learn to use dairy data and management tools in real-world settings.

Improving milk quality and animal well-being
Dr. Petersson-Wolfe's Extension program focuses on milk quality and animal well-being. She oversees the Virginia Tech Mastitis Laboratory, which serves as a statewide diagnostic resource by providing milk culturing services to dairy producers. The laboratory remains the cornerstone of her Extension programming, supplying valuable diagnostic information that helps producers identify and address milk quality challenges while supporting judicious antimicrobial use. Her research program is focused on improving mastitis detection using on-farm technologies, advancing precision livestock farming tools, and enhancing animal well-being through pain mitigation strategies and the development of novel approaches for mastitis prevention and treatment.

Building resilient dairy farms
Together, the Dairy Extension team is committed to delivering research-based solutions that strengthen the profitability, sustainability, and resilience of Virginia dairy farms. Through integrated research, teaching, and Extension programming, we will continue to provide producers with the knowledge, tools, and support needed to meet emerging challenges and ensure a vibrant future for the commonwealth's dairy industry.

Poultry Extension Update

Virginia Poultry Disease Task Force: A history of collaboration
A top priority for Virginia’s poultry sector is protection of flocks from avian disease threats such as Highly Pathogenic Avian Influenza (HPAI), which has taken a huge toll on poultry across the United States since 2022. Following an outbreak of avian influenza in the Shenandoah Valley in 2002, the Virginia Poultry Federation collaborated with the Virginia Department of Agriculture and Consumer Services, USDA’s Animal and Plant Health Inspection Service, the Virginia-Maryland College of Veterinary Medicine, and other entities to establish the Virginia Poultry Disease Task Force (VPDTF).

The VPDTF developed an avian influenza prevention and rapid response plan that includes protocols to reduce the chances of avian influenza outbreaks and to respond effectively should a flock become infected. Prevention hinges on biosecurity and flock surveillance protocols. Preventing disease introduction through strong biosecurity practices remains one of the most effective tools for protecting poultry health. Some guidance can be found here: Biosecurity: Five Steps to Protect Poultry from Avian Influenza (and Other Diseases).

The VPDTF meets at least quarterly to review and update the Virginia avian influenza plan. Over the years, the task force has conducted various tabletop exercises to test the effectiveness of our plan. Fortunately, Virginia has had relatively few commercial cases. Of about 1,000 cases of HPAI in commercial poultry flocks in all 50 states since 2022, just three were in Virginia — two turkey flocks in 2023 and a broiler chicken flock in 2025.

Advances in poultry welfare
Advancing poultry welfare continues to receive attention. Consumers, food companies, and producers are increasingly focused on management practices that promote bird welfare — essentially, the birds’ quality of life. Research and Extension efforts continue to evaluate practical, science-based approaches to improving welfare while balancing productivity and economic feasibility. A recent publication highlights how environmental enrichments can benefit both poultry and producers: How Environmental Enrichments in Chicken Houses Can Benefit Producers. In addition, a publication describes why poultry emotions matter: Why Measure Emotion in Poultry? Because It Matters!

Helping poultry producers stay prepared

When highly pathogenic avian influenza returned to Virginia, Virginia Cooperative Extension provided timely, science-based guidance to help commercial producers and backyard flock owners strengthen their biosecurity practices. The outreach highlighted the critical role Extension plays in protecting animal health and supporting Virginia’s poultry industry.  

Sheep Extension Update

Advancing sheep production through research
Sheep enterprises across the commonwealth have also benefited from strong market prices and profitability in recent years. Extension has focused on assisting with production and management education and applied research that supports the industry and its evolution. One example of this is the Southwest Virginia Ram Test, which takes place at the Southwest AREC in Glade Spring, Virginia. Now in its 14th season, this unique program provides a standardized post-weaning performance evaluation of growth and parasite resistance and serves as an educational tool for the sheep industry. The integrated Extension and research work with hair sheep and parasite resistance at the Southwest AREC is a primary focus of our sheep efforts. The work has two main components: the pasture-based ram test program, now more than a decade old, and research with the Katahdin flock using divergent genetic lines for parasite resistance. This unique breeding model has provided a better understanding of both basic and applied aspects of parasite management.         

Educational programs for sheep producers
Supporting these activities are educational programs such as the annual Shepherd’s Symposium in January, which is an online program offered over two consecutive evenings and features Extension specialists and others sharing timely information on sheep production and management topics. Lambing Schools, Sheep Basics Workshops, FAMACHA trainings, and shearing schools are also programs routinely offered for both new and experienced sheep producers.

Celebrating 50 years of the Virginia Ram Test
Finally, Virginia is home to the oldest and most continuously operated ram test program in the country. Last year, the Virginia Ram Test celebrated its 50th anniversary, a testament to its longstanding importance to the state’s sheep industry. This year’s annual sale and field day were held at the Shenandoah Valley AREC in Raphine, Virginia on August 22.

Five decades of producer-focused innovation

For 50 years, Virginia Tech’s performance-tested ram program has helped sheep producers make informed breeding decisions that strengthen flocks and improve profitability. By combining research, Extension, and industry partnerships, the program continues to advance sheep genetics and support producers across Virginia and beyond.

Honoring Virginia's livestock leaders

Every fall, the Virginia Livestock Hall of Fame recognizes individuals whose leadership, innovation, and service have shaped the commonwealth’s beef, dairy, pork, sheep, and horse industries. Each year, new inductees are honored at the Alphin-Stuart Livestock Arena, where their contributions are celebrated alongside the generations of leaders who have advanced Virginia agriculture. Inductees are nominated by the Virginia Cattlemen’s Association, Virginia Pork Industry Association, Virginia Sheep Producers Association, Virginia State Dairymen’s Association, and Virginia Horse Council.
