DAY 1 AT 2025 PSA ANNUAL MEETING

This lecture explored legal issues facing the poultry industry, with a focus on laws and regulations affecting animal welfare and food safety. Attendees gained insights into how legal frameworks influence scientific research and the broader agricultural landscape.

10:15 AM | Symposium: Gut check: Exploring tools, techniques, and future directions in microbiome research

This symposium convened leading experts to discuss the latest advancements in analytical tools and technologies for studying the poultry intestinal microbiome.

• Participants engaged with presentations on microbiome profiling techniques, innovative data analysis tools, and the integration of cutting-edge technologies in microbiome research.
• Additionally, a roundtable discussion fostered dialogue on current challenges, opportunities, and future directions in microbiome analysis, highlighting its implications for poultry research among academics and industry professionals.

1:15 PM | Informal Nutrition Symposium: Dynamic feed formulation in commercial poultry nutrition

Historical approaches to poultry feed formulation have been rooted in static information, both in terms of setting nutrient specifications for stages of production, and assumptions regarding nutrient content and availability in feedstuffs.

• Dynamic feed formulation attempts to integrate real-time analysis of feedstuff nutrient composition and availability with more precise nutritional requirement information based on age, body weight, productivity, health status and other factors.
• Real-time adjustments to feed formulation to accurately meet the nutritional needs of poultry will increase efficiency and productivity, but advanced and complex information on the supply (feedstuffs) and demand (bird nutrient requirements) must be integrated accurately and quickly.
• The 2025 Informal Nutrition Symposium bringed together an outstanding panel of speakers to address the major topics that must be addressed in order to adopt a dynamic feed formulation approach.

1:15 PM | Symposium: The many facets of glucocorticoid actions from stress and beyond

Glucocorticoids have many physiological functions and the stress response is just one of them. However, in much of poultry science, they are considered solely as stress hormones and assumptions may lead to misinterpretation of data.

• The purpose of this symposium was to give a broad historical and scientific overview of the many functions of glucocorticoids in poultry and what is known in the wild bird literature.
• Physiology is becoming a steadily decreasing component of PSA and often misinterpreted by other fields.
• It is our hope to spark a renewed interest in physiological research and to shed light on the many functions of glucocorticoids beyond just the stress response.
