Members of CORE present research at K-State’s “Posters, Pinot, and Partnerships” Event
Christy Hanthorn, Natalia Cernicchiaro, and Ashley Thackrah presented their poster, “Barrier or Breach? Assessing Swine Housing Features for Mosquito Threats,” at the Posters, Pinot, and Partnerships event held on October 9, 2025, at Hale Library. Conducted in collaboration with researchers from the USDA Agricultural Research Service (ARS) National Bio and Agro-Defense Facility (NBAF), the study explores how swine housing design affects mosquito abundance and disease risk—advancing efforts to strengthen biosecurity in livestock production systems. Sponsored by the Office of the Vice President for Research and K-State Libraries, the Posters, Pinot, and Partnerships series fosters collaboration and knowledge exchange among K-State scholars. The October session highlighted research in Enabling Technologies and Global Food Security and Biosecurity.
Research Update: Dr. David Renter
Dr. David Renter presented “Making Treatment Choices for Reducing BRD and Death Loss” at the 2025 K-State Beef Stocker Field Day on September 25th. High Plains Journal highlighted this presentation and the complexities of treating bovine respiratory disease in the article “K-State research underscores complexity of treating bovine respiratory disease.”
2025 American Association of Bovine Practitioners Annual Conference
The American Association of Bovine Practitioners (AABP) Annual Conference took place September 11-13, 2025, in Omaha, Nebraska. CORE members Dr. Mike Sanderson, Dr. Vanessa Horton, and Torre Dunlea presented oral presentations, and Brittany Hirsch, KSU DVM student, presented a poster.
Torre Dunlea was awarded 3rd place in the Graduate Student Competition for her presentation entitled “A quantitative model of the risk of FMD transmission following cattle movements during an outbreak.”
Dr. Vanessa Horton presented “Understanding metaphylaxis practices for cattle at uncertain risk for bovine respiratory disease across U.S. feedlots: a survey of veterinary consultants and feedlot managers.”
Dr. Mike Sanderson presented on Dr. MaRyka Smith’s work, “Model-based impacts of improved traceability of cattle in Foot and Mouth Disease outbreaks in the United States.”
Brittany Hirsch presented a poster titled “On-farm guidance for preventing cattle death loss due to nitrate poisoning from contaminated water sources.”
2025 Academy of Veterinary Consultants Summer Conference
CORE members, Drs. Vanessa Horton, Christy Hanthorn, and Natalia Cernicchiaro attended the 2025 Academy of Veterinary Consultants (AVC) Summer Conference from August 7-9, 2025 in Norman, Oklahoma. Dr. Horton, PhD candidate, presented findings from our nationwide survey on metaphylaxis practices for cattle at uncertain risk of bovine respiratory disease, offering valuable insights to support evidence-based decisions in U.S. feedlots. This invitation reflects CORE’s continued engagement with industry stakeholders and commitment to providing research that supports evidence-based management decisions in cattle production systems.
2025 VRSP Student
KSU DVM student Brittany Hirsch participated in the Veterinary Research Scholars Program (VRSP) this summer and presented her research poster, “On-farm guidance for preventing cattle death loss due to nitrate poisoning from contaminated water sources” at the 2025 KSU VRSP poster session. Brittany was mentored by Drs. Scott Fritz, Christy Hanthorn, and Mike Sanderson.
