Kansas State University research has offered a glimpse into the potential of niacin supplementation in broiler diets — but questions remain about the exact benefits producers might expect from such a move.
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.
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.
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, 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.

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.

Broiler activities like locomotion and movement can be quantified using the broiler activity index (BAI), which has been associated with broiler leg health, productivity and physical conditions. However, current calculation procedures are not user-friendly, requiring extensive training. A new user-friendly web-based AI system could be the answer.
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?
