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.

Multi-strain bacterin vaccine demonstrates broad protection against spotty liver disease

Recently, Campylobacter hepaticus was identified as the causative agent for chicken spotty liver disease (SLD), an illness which manifests as acute infectious hepatitis and causes a significant drop in egg production and high mortality in layer chickens. Researchers from Iowa State University, led by Orhan Sahin, DVM, PhD, are studying Campylobacter bacterins in the control of SLD.

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.

Common causes of mortality in cage-free egg production systems

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.

Robotic system shows promise for detecting mortalities but improvements needed

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.

Poultry experts urge ‘village’ approach to control H5N1 dairy outbreak

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.

Embryologist eyes blue-light treatment to end male-chick culling

Culling day-old male chicks from egg-laying hens is an on-going dilemma for the global poultry industry, resulting in the culling of 7 billion male chicks annually. At the 2025 International Poultry Scientific Forum, Yuval Cinnamon, PhD, outlined the work his research team has done on the Golda hen and optogenetics — a blue-light treatment — to halt the development of male chicks and thereby the need for culling.
