So, “recruitment and retention” in the Ag Industry, Swine segment and the Vet Med platform………..wow !! That’s a challenge of it’s own. Let’s break down some statistics, some survey data, some fun history, peak at some trend lines, and dive off into the deep end, with or without our life jacket on, you choose, and see what happens !
Dr. Mike Apley, Professor, Kansas State University
Antimicrobial stewardship (AMS), like the term sustainability, has different meanings to different people. The AMS term is best understood in the context of efforts to address AMS within different veterinary segments as well as in human medicine. The ultimate question is whether there are practical applications of AMS at the decision point for each antimicrobial use.
Moderators: Isadora Machado and Peng Li
Ethan Aljets, Veterinary Microbiologist, Iowa State University
An examination of the detection frequencies for porcine RVA, RVB, and RVC in US swine herds by analyzing PCR data obtained from the Iowa State University Veterinary Diagnostic Lab from 2015-2022.
Dr. Gaurav Rawal, Graduate Research Assistant, Iowa State University
TaqMan probe-based singleplex real-time RT-PCR assays for specific detection of six PRRSV-2 MLV vaccine viruses (Ingelvac PRRS MLV, Ingelvac PRRS ATP, Fostera PRRS, Prime Pac PRRS, Prevacent PRRS, and PRRSGard) were evaluated. A multiplex real-time RT-PCR for detecting the three most commonly used vaccines (Prevacent PRRS, Ingelvac PRRS MLV, and Fostera PRRS) were further developed and validated. The data will be presented and the clinical application of these PCR assays will be discussed.
Dr. Meredith Petersen, Post-Doctoral Research Associate, Swine Medicine Education Center (SMEC), Iowa State University
In veterinary medicine, telehealth techniques have the potential to provide increased surge capacity for veterinarians in an emerging disease outbreak, relief for veterinarians in the increasingly common shortage-areas, and increased caseload and mentorship of veterinary students and new veterinarians without an added biosecurity risk. This presentation describes four key challenges to adopting telemedicine and strides to address these opportunities.
Dr. Guilherme Cezar, Graduate Research Assistant, Iowa State University
Swine Disease Reporting System: 2022-2023 trends of swine pathogen detection in the U.S using diagnostic data from veterinary diagnostic laboratories from the National Animal Health Laboratory Network.
Dr. Marta Mainenti, Clinical Assistant Professor, Iowa State University Veterinary Diagnostic Laboratory
This study aims to provide an updated overview of salmonellosis in commercial pigs based on the diagnostic cases diagnosed with Salmonella sp. infection at the Iowa State University Veterinary Diagnostic Laboratory (ISU VDL) in the past decade.
Dr. Perry Harms, Director of Health Assurance, PIC
Implementation of a medicated early wean program, combined with strict biosecurity and intensive surveillance for the elimination of A. suis, MHR and MHS.
Dr. Loni Schumacher, Clinical Assistant Professor, Iowa State University
This presentation describes the attenuation phenotypes and protection against wild type challenge in piglets using a non-S INDEL PEDV isolate that was serially passed up to 200 times in cell culture. Overall, the P200 strain appears capable of providing protective immunity and is a promising MLV vaccine candidate.
Dr. Jianqiang Zhang, Professor, Iowa State University
PRRSV-naive pigs at 3-4 weeks of age were used to evaluate the protective efficacy of six commercial PRRSV-2 MLV vaccines against the emergent PRRSV L1C variant strain. At 35 days post vaccination (DPV), all pigs were challenged with PRRSV L1C variant strain and all surviving pigs were euthanized and necropsied at 49 DPV (14 days post challenge [DPC]). Results will be presented.
Dr. Gabi Doughan, Post-Doctoral Research Associate, Iowa State University
This presentation will cover on why water is an underestimated biosecurity risk, introduce factors that contribute to water line biofilms in swine barns, and focus on methods in assessing water biology on farms.
Dr. Joel Sparks, Veterinarian, AMVC
This is an overview to practitioner’s perspective and experience with next generation sequencing and how it may be used in the clinical setting with PRRSV.

Dr. Kimberly Crawford, Managing Veterinarian, VRI
This presentation will highlight the results of a blinded, controlled study measuring the efficacy of ivermectin administered to weaned pigs after a PRRSV 1-4-4 L1C challenge. Spoiler alert – there is more work that needs to be done to officially answer the question.
Dr. Matt Ackerman, Private Practitioner, Pork Veterinary Solutions
When a disease break occurs in a unit, it is easy to chalk it up to bad luck and move on. However, progress is made when we learn from our mistakes and take corrective action. In this presentation we will share some things we learned from a field investigation of a disease break situation at a Gilt Developer Unit.
Dr. Derald Holtkamp, Professor, Iowa State University
Outbreak investigations are designed to learn where producers should devote time and effort, and where to prioritize the most significant biosecurity hazards on the farm. The only way to identify where those biosecurity hazards are is to be deliberate about the investigation. In 2021, the Swine Health Information Center funded the development of an industry-standard outbreak investigation instrument. In this presentation, a web-based version of the instrument to make it easy for veterinarians to use and to capture data from the investigations in a secure industry-wide database will be introduced.
Dr. Tom Petznick, Veterinarian, ArkCare
Porcine sapovirus has entered into the differential diagnosis list for diarrhea in mid to late lactation and the early nursery phase. We will cover its emergence, clinical signs, diagnostic methods, effects on production and mitigation steps. We will also delve into what we still don’t understand about the pathogen and its contribution to disease.
Dr. Mike Rahe, Assistant Professor, North Carolina State University
117 cases of influenza negative tracheitis and bronchitis in weaned pigs were evaluated for the presence of porcine astrovirus 4 within lesions using RNAscope. Here, we show a strong association between this emerging virus and respiratory disease in young pigs.
