Plant polyphenols demonstrated effectiveness against multi-drug-resistant Salmonella enterica serovar DT104, suggesting their potential in the fight against antimicrobial resistance (AMR) and foodborne illness, according to Auburn University researcher Hunter Sheffield, PhD student.
When enteritis strikes, the challenge is identifying the exact cause. In February 2023, Huvepharma’s research and development personnel received a call about enteritis symptoms in two commercial antibiotic-free turkey houses. A team went out to conduct a thorough field investigation to determine precisely what was going on with the flocks.

While some mortality is expected in all layer flocks, regardless of the housing type or breed, the rate and causes can vary depending on the production system. Cage-free systems may not inherently have higher mortality than cages and experience in managing birds in cage-free systems plays a big role in maintaining low mortality.
Coccidiosis guru Steve Fitz-Coy, PhD, started his career in the early 1980s. Some 40 years later, coccidiosis continues to be one of the most common and costly diseases of poultry worldwide. And Fitz-Coy, a poultry scientist at Merck for the past 24 years, is still the go-to guy when an outbreak is suspected.
US broiler operations commonly reuse litter for environmental and economic reasons. Research and real-world results have shown that the first broiler flock raised on brand-new litter underperforms flocks raised on used litter, but the reasons remain unclear.
Poultry farmers face major challenges finding and disposing of mortalities on the farm, but a commercial manufacturer has created a mobile robotic system equipped with multiple cameras that traverses the ceiling to identify mortalities in the barn. Tanner Thornton, University of Tennessee, described a test of the system at the 2025 IPPE.
Waiting for the H5 influenza outbreak to slow down in dairy cattle is no longer enough for the AAAP and PSA. The two groups teamed up to push for more action to help the dairy industry address its growing outbreak of highly pathogenic avian influenza. In PSA’s Unplucked podcast “H5 Influenza Uncovered” veterinarians from both organizations discussed this topic.
In response to the ongoing H5N1 avian influenza outbreak and questions surrounding the use of vaccination to control the disease, several experts from the American Association of Avian Pathologists (AAAP) created a fact sheet on H5N1.
University of Georgia researchers, led by Maricarmen Garcia, PhD, have developed a new genotyping assay for analyzing clinical samples of infectious laryngotracheitis virus (ILTV). Identifying the genotype of the outbreak-related virus and determining its genetic relationship to field or vaccine strains is key to diagnosing ILTV.
Coccidiosis ranks in the top 10 poultry health concerns worldwide, and the cost of its control can be significant. Kayla Price, PhD, poultry technical manager, outlined points to consider and how to build an arsenal of alternative products to manage coccidiosis in poultry flocks.
Two direct-fed microbials (DFMs) have shown promise in reducing health problems associated with Enterococcus cecorum in broilers.
