USDA Publishes New Standards for Organic Livestock and Poultry Production, Promotes More Competitive Organic Market

Agriculture Secretary Tom Vilsack today previewed the Organic Livestock and Poultry Standards (OLPS) final rule. This new rule establishes clear, strong and consistent standards for organic livestock and poultry production, levels the playing field for organic livestock farmers, ranchers and businesses and promotes fairer, more competitive markets for their products, while providing consumers with more transparency about their purchases.

"USDA is creating a fairer, more competitive and transparent food system. This organic poultry and livestock standard establishes clear and strong standards that will increase the consistency of animal welfare practices in organic production and in how these practices are enforced," said Vilsack. "Competitive markets help deliver greater value to all producers, regardless of size."

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Li-Hsuan Chen, postdoc researcher at Aarhus University, discusses how porcine intestinal cell lines and organoids can help study the impact of nutrition on gut health. He explains how in vivo piglet trials identify diet-driven shifts in microbiota and metabolites, while in vitro models allow researchers to test specific metabolites, barrier function, immune markers, and future organ-on-chip systems before moving back to animal studies. Listen now on all major platforms!

"In vitro models can reduce early animal use by helping researchers screen nutritional candidates before moving back to in vivo trials."

Meet the guest: Dr. Li-Hsuan Chen / li-hsuan-chen-9a95a7279 is a postdoc researcher at Aarhus University in Denmark. Research focuses on porcine gut health, host-microbe interactions, cell lines, and organoids, with PhD work at Aarhus University studying how dietary protein and amino acid levels shape gut microbiota, microbial metabolites, and intestinal epithelial responses.
