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.
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.
Research led by Chloe Phelps, a graduate student in the Virginia Tech School of Animal Sciences, evaluated poultry behavior and its impact on birds’ emotional state and subsequent welfare.
Those who work in poultry welfare should focus on “progress, not perfection” when designing and implementing ways to improve birds’ quality of life, according to industry expert, Kate Barger Weathers, DVM, KB Welfare Consulting, South Carolina.
Lameness in poultry, characterized by impaired mobility or abnormal gait, is a major concern in fast-growing birds such as broilers and turkeys. Intensive genetic selection for rapid body weight gain and increased breast muscle mass can result in disproportionate growth between the muscular and skeletal systems, predisposing birds to locomotor problems. Stephanie Kulbacki, University of Georgia, provides an overview of lameness and ways to assess gait.

Extreme weather events, such as heat waves, droughts, freezing conditions, floods, tornadoes, and hurricanes, can affect poultry flocks in many ways. The severity of their impact depends on both the type of event and the geographic location.

Japanese quail (Corturnix corturnix japonica) are the smallest farmed birds and contribute to approximately 10% and 0.2% of the global table egg and meat markets. Rosie Whittle, PhD, discusses housing, management and key welfare issues associated with farming these birds.
