Avian flu: How scientists and farmers are working to adapt

The avian flu virus continues to affect poultry producers and dairy farms in 2025. In North Carolina alone, the virus has resulted in the loss of millions of birds on poultry farms. Meanwhile, less than a year after avian flu was first detected in dairy herds, a new strain of the virus has been found in Nevada cows. Matt Koci, PhD, a virus expert and professor with NC State University’s Prestage Department of Poultry Science, offers insights.

USDA Salmonella vaccine reduces Salmonella Enteritidis loads in broilers

Enteritidis is one of the most common serotypes of Salmonella globally and is historically associated with poultry. Unfortunately, antibiotic resistance is making it more challenging to treat.

Colored light differentially impacts broiler activity, tibia morphology

Mobility and leg problems are common in modern-day broilers, which are bred for high breast-muscle yield. Extra activity can help the birds support the extra bodyweight and prevent skeletal disorders. Could colored lighting encourage broilers to be more active and less prone to leg problems?

USDA announces biosecurity assessments, audits to support HPAI prevention

To help improve biosecurity on individual premises and prevent introduction or spread of highly pathogenic avian influenza (HPAI), USDA recently announced plans to expand assessments and audits available to commercial poultry producers.

Microbial mix could help improve coccidiosis management in broilers

Using a dietary supplement containing a blend of Bacillus bacterial strains appears to positively affect the intestinal health and immunity of broiler chicks after a coccidia challenge, according to a Frontiers in Microbiology report.

Enterococcus survey illustrates pathogen trends on poultry farms

A survey of more than 600 Enterococcus samples from Mississippi poultry farms revealed that E. cecorum primarily affects broilers, while E. faecalis is more problematic in hatcheries and very young chicks.

Synthetic anticoccidials for poultry: Are some more resistance-prone than others?

Synthetic anticoccidials, also referred to as “chemicals,” are often considered the most efficacious tools to mitigate coccidiosis in poultry. Yet, despite their effectiveness, veterinarians and producers sometimes hesitate to incorporate them into control programs due to the concern of chemical-resistant Eimeria strains developing.

Intestinal health in poultry: Understanding viral, bacterial and coccidiosis challenges

Having been linked to everything from yield gains, feed-conversion ratio and immunity to disease tolerance, mortality and animal welfare, intestinal health is foundational to the success of poultry operations today. Three poultry-health experts took part in an intestinal health webinar in which they discussed viral, bacterial and coccidial challenges in poultry, their impact on gut health and potential management strategies.

USDA scientist: What’s the latest on HPAI transmission, infection?

HPAI virus continues to take a heavy toll on US poultry while raising concerns about transmission to other species, including humans. How serious are these concerns and what are the transmission routes?

NCC petitions FDA to relieve HPAI-exacerbated egg shortage

To address the strain on the nation’s egg supply and resultant record egg prices due to the current HPAI outbreak, the National Chicken Council petitioned the FDA to reverse or modify current regulations that compel the broiler industry to discard nutritious and safe eggs.
