Cutting-edge poultry research was showcased at the 2025 International Production & Processing Expo (IPPE) during the TECHTalks sessions, where four leading researchers presented findings from recent studies funded by the U.S. Poultry & Egg Association (USPOULTRY) and its Foundation. These presentations are now available for viewing on USPOULTRY’s YouTube channel at youtube.com/USPOULTRY.
Key Research Highlights
Effects of Dark Periods on Broiler Performance & Welfare
Dr. Brian Fairchild, University of Georgia
- Investigated the impact of zero, four-, and six-hour dark periods during the first seven days of broiler growth
- Challenged the traditional practice of 23-24 hours of continuous light to maximize feed intake
- Findings: Providing a dark period from the start does not negatively impact broiler performance, offering potential welfare benefits
Probiotic-Based Vaccine for Clostridial Dermatitis in Turkeys
Dr. Ravi Kulkarni, North Carolina State University
- Developed a probiotic-based oral vectored vaccine using Lactococcus lactis to protect turkeys from Clostridial dermatitis
- Findings: Non-toxic C. septicum antigens (ntATX) demonstrated protective abilities, making them strong vaccine candidates for both subcutaneous and oral administration
Upgrading Molecular Diagnostic Tools for Infectious Laryngotracheitis Virus (ILTV)
Dr. Maricarmen Garcia, University of Georgia
- Explored whether ILTV recombinant antigens delivered through natural mucosal routes could enhance T-cell responses
- Findings: Boosting immunization is critical for improving DNA vaccine effectiveness, but tested delivery methods did not significantly reduce virus replication
AI-Based Broiler Activity Index for Health & Welfare Monitoring
Dr. Guoming Li, University of Georgia
- Developed a web-based AI system to quantify broiler activity index, an important indicator of leg health, productivity and overall welfare
- Findings: The user-friendly, open-source platform allows researchers to analyze movement data from video footage without extensive programming knowledge
