Artificial light remains the industry standard in modern broiler production because it is highly controllable and can provide a consistent, uniform light source. While some studies demonstrate the benefits of artificial lighting, other research suggests that the same environment may negatively affect ocular and leg health.
In this Q&A, Daniel Maekawa, DVM, PhD, technical services veterinarian with Merck Animal Health, discusses how producers can approach aMPV with a practical, integrated mindset — bringing together biosecurity, vaccination and management to reduce complex-level impact.
Turkey poults develop a wide range of behaviors besides eating, sleeping and resting in their first week of life. They also learn play behaviors and activities to comfort themselves, according to research by Alexandra Jackson, doctoral student, Auburn University.
Field data from a large commercial layer enterprise confirm that Cargill’s Biostrong™ C-Protect — a postbiotic/phytogenic blend — supports improved livability in layers in the face of avian pathogenic Escherichia coli (APEC).
Heat stress affects poultry farms everywhere — even in Canada, where poultry producers battle hot, humid conditions in the summer. Deborah Adewole, PhD, associate professor, University of Saskatchewan, has focused her recent work on nutritional strategies to reduce heat stress and discussed her research in a webinar hosted by Canadian Poultry.
Ventilation shutdown with heat and humidity may be superior to other methods of broiler depopulation under controlled environmental conditions, but this method requires further study under industry-like conditions, according to researchers at North Carolina State University.
Raised to maximize meat production, commercial turkey toms are bred to grow quickly and gain weight in a short time. This begs the question whether the bird’s skeletal system meets that developmental challenge.
As resistance continues to erode the effectiveness of traditional anticoccidial programs in turkeys, veterinarians are increasingly focused on strategies that protect birds while preserving available tools. A multi-year field experience with a US heavy tom producer suggests that coccidiosis vaccines can play a practical role in conventional rotation programs.

In some regions, the threat of infectious bronchitis virus flare-ups has shaped a long-held industry mindset: when bronchitis pressure rises, it may be safer to pull back on live Newcastle disease vaccination to avoid “stacking” respiratory vaccines. However, Roy Jacob, DVM, PhD, senior key account veterinarian at Boehringer Ingelheim, says this need not be the case.
Abstract: Sample to vaccine via an integrated cross-functional NGS network
Broiler welfare assessment has moved beyond a framework based solely on minimizing harm to one that incorporates opportunities for positive affect. Jenna Boewe, graduate student, and Marisa Erasmus, PhD, Purdue University, explore this new paradigm in animal welfare as it applies to today’s broilers.
