Coccidiosis control: Why vaccination wins — and how to do it right

Coccidiosis doesn’t just lurk in poultry houses — it thrives there. For decades, producers have relied on synthetic anticoccidials and ionophores to keep it in check. But with growing resistance and increasing pressure to reduce antibiotic use, more operations are turning to vaccination as a sustainable, effective alternative.

UGA case study: Chlorine demonstrates mixed results in spotty liver disease outbreak

Campylobacter hepaticus has been identified as the causative agent in spotty liver disease, so when Roel Becerra, DVM, received a phone call from a producer that had free-range, antibiotic-free, brown layer hens with SLD, he and fellow investigators decided to study chlorine as a possible treatment.

Stocking density variably affects broiler activity, welfare

Providing the proper stocking density to maximize broiler productivity, welfare and profitability is a balancing act. Because the birds grow dramatically in just a few weeks, space and environmental demands continuously evolve.

Caution needed when adjusting broiler calcium concentration, limestone particle size

Reducing dietary calcium concentrations in broiler diets can increase calcium and phosphorus digestibility, but deviating from recommended levels can come with costs, according to the results of an Auburn University study.

Cremers: HPAI biosecurity burnout is real among turkey workers

In the “Let’s Talk Turkey” episode of the Unplucked podcast produced by the Poultry Science Association, Carrie Cremers, DVM, manager of technical service and animal welfare at Jennie-O, discussed how the weight of ever-present HPAI has led to biosecurity burnout among workers.

Auburn study shows broiler chicks’ response to new, used litter

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.

Auburn University researchers: Outsmart resistant bacteria with polyphenols

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.

Case report: In-depth investigation of enteritis in turkeys reveals cochlosomiasis

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.
