Dr. Tom Petznick the 2023 Allen D. Leman Science in Practice Award Winner

May 29, 2023

Dr. Tom Petznick, a swine veterinarian based in Omaha, NE will receive the 2023 Science in Practice award at the Allen D. Leman Swine Conference in September. For over 25 years Petznick has successfully met client needs through a balance of science-based and practical approaches to livestock health. His tireless efforts led to recognition of the widespread and largely unknown role of sapovirus in pig production systems. Also, his expertise in managing purebred sows has made him an in-demand consulting swine veterinarian.

Petznick is respected as a thought leader in porcine sapovirus (PSaV), a calicivirus that has been detected in pigs with and without diarrhea. A PSaV infection is difficult to differentiate from other enteric diseases based on clinical signs alone. PSaV has been found as the sole pathogen involved in diarrhea cases, but more commonly is found in coinfection scenarios.

The scarcity of epidemiological understanding of PSaV motivated Petznick to partner with state diagnostic laboratories to identify PSaV as the causative agent in numerous cases. He also worked with prescription vaccine platforms to develop novel vaccine strategies for his affected clients.

Video: Building Better Barns: Innovations in Hog Facility Design with PSI’s Tim Messinger

In this exclusive interview from the 2025 Iowa Pork Congress Rachel Fishback and Swineweb sit down with Tim Messinger, a seasoned expert from Precision Structures Inc. (PSI) of Wellman, Iowa, to delve into the latest trends and innovations in hog barn construction and remodeling.

With nearly two decades at PSI, Tim shares his journey from draftsman to sales, highlighting the company’s comprehensive services in building farrow-to-wean complexes, finishers, and nurseries. He emphasizes the critical role of proper site layout and grading in barn construction, ensuring long-term efficiency and scalability for pork producers.

Tim also discusses the increasing importance of advanced ventilation systems and smart controllers like Maximus and AP Edge, which offer producers enhanced monitoring and control over barn environments. As construction costs have risen, PSI has seen an uptick in remodeling projects, particularly in slat replacements, roof refurbishments and barn gating remodels to extend the lifespan of existing facilities.

A key takeaway from Tim is the value of partnering with reputable builders who offer robust post-sale support. PSI’s dedicated service team stands ready to assist clients 24/7, addressing emergencies and ensuring optimal barn performance.

For pork producers looking to build or upgrade their facilities, this conversation offers valuable insights into best practices and the latest industry developments.
