The University of Nebraska–Lincoln is boosting its swine research through recent facility upgrades and innovative projects aimed at improving pig health, reproduction, and sustainability in pork production.
New gate feeders, installed in the Animal Science Complex with support from the Nebraska Pork Producers Association, will allow researchers more space to study pigs in controlled environments. These changes support groundbreaking work in reproductive science and animal nutrition.
“Interest and momentum in swine research are growing at UNL,” said Amy Desaulniers. Researchers are shifting focus toward boars, aiming to develop genetic tolerance to gestational heat stress—a factor that greatly affects fertility. Boars contribute more to herd productivity due to their use in artificial insemination, making fertility crucial.
Meanwhile, Brett White is studying hormone indicators to identify subfertile boars early. Removing low-fertility animals from breeding programs could boost reproductive efficiency and profitability.
Other research focuses on improving gut health without relying on antimicrobials. Doctoral students are testing natural feed additives, including black seed oil and Jerusalem artichoke fiber, to promote stronger immune systems and prevent diseases like salmonella and E. coli.
Researchers like Duncan Paczosa are examining how beneficial gut bacteria can protect pigs from harmful mycotoxins found in common feeds. Supporting these microbes could reduce feed-related health issues.
UNL is also advancing vaccine development. Hiep Vu and Eric Weaver are working on next-generation DNA vaccines to protect pigs against viruses like swine influenza. These new approaches offer broader protection and faster development than traditional vaccines.
Technology is also playing a role. Ty Schmidt’s team developed NUtrack Livestock Monitoring, a system that uses video to track pig behaviour. It helps identify sick or stressed animals quickly, improving health and productivity.
UNL continues to lead swine research globally. “What we are doing in the lab here at Nebraska is setting the bar on an international level,” said Weaver.
