2015 PSA Annual Meeting

Date: 27 July 2015
Location: Louisville, Kentucky, USA

We’ve brought together a team of experts to help poultry producers answer the question of how a bird’s gut health can impact the quality and quantity of the poultry we consume. Entitled "From Egg to Plate – The Influence of Gut Health". The symposium will include the following sessions: 

  • Preparing for Food Safety Modernization Act (FSMA at the Feed Mill”- Dr. Henry Turlington, Director of Quality & Manufacturing Regulatory Affairs at American Feed Industry Association (AFIA),  will outline what  the FSMA means in practical terms for live operations and how it will affect  their day-to -day activities.
  • Laying the right foundation – getting your birds off to a healthy start”Dr. Suzanne Dougherty, Consulting Poultry Veterinarian, will discuss the  influence that intensive  live production can have on gut health from hatch to finish.
  • Back to the future – Cocci management going forward Dr. Charles L. Hofacre Professor, Director of Clinical Services  at the University of Georgia,  will discuss management of coccidia without ionophores and the effect this has on gut health.
  • “The impact of nutrition on gut health” - Dr. Peter Plumstead, Associate Professor, Monogastric Nutrition at the University of Pretoria, will  outline how the strategic use of feed additives can help tackle microbial imbalance.
  • “Controlling the unknown”  Dr. Arturo Tanus, Director of Technical Services at Butterball, LLC, will provide insight into live production effects on needed plant interventions.

The symposium is open to all registered attendees of the 2015 PSA Annual Meeting.  There was standing room only at last year’s symposium, so early arrival is recommended. Presentations will be available upon request following the meeting; please send your name, job title, company name and the name of the presentation you want to receive to
