Matt Claeys, the CEO of the National Swine Registry, spoke to The Pig Site’s Sarah Mikesell at the 2023 World Pork Exposition in Des Moines, Iowa, USA.

Who is the National Swine Registry?

“National Swine Registry wears a number of hats,” said Matt Claeys, CEO of National Swine Registry. “We are the pedigree association for the Duroc, Hampshire, Yorkshire and Landrace hogs.”

National Swine Registry has an open membership of breeders that provide purebred genetics and crossbred genetics, a purebred-influenced crossbred type of hogs.

“We have the show operation in the junior program,” he said. “The purebred hogs are really a large part of that program. We've got the purebred shows for open and junior participants.”

Video: Seaweed-Based Solutions: Building Natural Performance in Modern Swine Production

In today’s pork industry, producers are under increasing pressure to do more with fewer inputs—while maintaining performance, improving animal health, and meeting sustainability expectations.

we sit down with Sylvain David and Scott Preston from Olmix to explore how seaweed-based solutions are emerging as a foundational tool in modern swine nutrition.

Rather than acting as simple alternatives, these solutions are designed to support gut health, immune resilience, and overall system consistency—especially during key stress periods like weaning, feed transitions, and disease challenges.

The conversation dives into:

• What seaweed-based solutions actually are and how they work

• Why consistency and standardization matter in “natural” products

• How gut health connects to immune function and performance

• Where producers are seeing real-world impact today

• The role of natural solutions in the future of sustainable pork production
