2023 Poultry Science Association Highlights Day 1

Podcast Topic

Today’s episode was filmed at the 2023 Poultry Science Association Annual Meeting in Philadelphia, PA. Balchem’s technical team chose abstracts of interest from the meeting and those researchers are our guests today.

Halley Poultry Consulting; Addison Elstner, Texas A&M University; Dr. Chasity Pender, DSM Nutritional Products; Dr. Valentina Caputi, USDA-ARS Poultry Production and Product Safety Research Unit; and Dimitri Malheiros and Dr. Ken Anderson, North Carolina State University

Episode 78: 2023 Poultry Science Association Highlights Day 1


We kick off the show with Andy Vance, Executive Director of the Poultry Science Association. Andy speaks to the growth of the conference, the presentations and attendance and reinforces that the Poultry Science Association exists to advance science in the poultry industry. (01:20)

Our second guest is Dr. John Halley with J. Halley Poultry Consulting. John conducted an industry survey about how companies handle data. Are companies digitizing data or just staying with what they’ve been doing? John’s presentation covered how data flows through poultry companies today, as well as where we may be going in the future. (23:36)

John’s abstract was titled: “Current Data Insights and Practices for a Poultry Nutritionist” Next on the guest roster is Addison Elstner from Texas A&M University.

Addison’s research objective was to use a different basal diet than traditional corn and soy to stress birds with high inclusions of other cereal grains. This effort was to create a preliminary model of different cereal diets and their impact on intestinal health, performance and animal welfare. This preliminary work builds a foundation for the addition of feed additives and enzymes to those nontraditional diets in the future. (30:16)

Addison’s abstract was titled: “Phase ingredients change in the diet formulation as a possible model to test feed additive efficacy in broiler chickens”

Our fourth guest is Dr. Chasity Pender from DSM Nutritional Products. Her abstract presented data compiled over the past year for vitamin A recovery levels. The DSM internal laboratory had samples of broiler, broiler breeder vitamin premixes, and broiler and broiler breeder feeds. With those samples, they measured vitamin A recovery levels and evaluated the variation in the different feedstuffs. (32:55)

Chastity’s abstract was titled: “Evaluation of Vitamin A Recoveries in Broiler and Broiler Breeder Premixes and Finished Feeds”

The next guest in our lineup is Dr. Valentina Caputi with the USDA-ARS Poultry Production and Product Safety Research Unit in Fayetteville, Arkansas. The main objective of her research is to look for alternatives to antibiotics to fight the carriage of foodborne pathogens in the poultry industry. Dr. Caputi’s specific expertise is the study of the enteric nervous system, which is the nervous system that is intrinsic on the gut wall and is distributed throughout the overall gastrointestinal tract. Her abstract evaluated how heat stress during the pre-harvest stage of poultry production affects the enteric nervous system, the intestinal microbiota, and overall gut health and how this can predispose the animal to be susceptible to colonization by a food pathogen, such as salmonella or campylobacter. (39:30)

Valentina’s abstract was titled: “Heat stress induces regional-dependent modulation of aquaporin 4 expression in the enteric nervous system of broiler chickens”

Lastly, we are joined by Dimitri Malheiros and Dr. Ken Anderson, from North Carolina State University. Dimitri’s research assessed cage densities during the pullet rearing phase. While other previous studies focused on increased stocking densities, Dimitri and Dr. Anderson wanted to focus on lower stocking densities to evaluate if pullet welfare would be improved in less dense cages. (49:05)

Dimitri’s abstract was titled: “Influence of cage rearing density on pullet growth parameters and fearfulness.”
