Broiler performance can be affected by many environmental stressors, including air temperature and quality, social interactions, litter moisture and quality, and pathogens. These stressors lead to decreased feed intake and subsequent growth as well as physiological responses that can further reduce performance and disease resistance - commonly referred to as the “fight or flight” response. One hallmark of stress response is an elevation in circulating levels of corticosterone (CORT). A negative side-effect of elevated CORT is diminished feed intake and immune responses to environmental pathogens common in poultry houses that can lead to disease states. This consequence of environmental stress is potentially exacerbated by the absence of antibiotics in antibiotic-restricted poultry production. Therefore, this objective is aimed at approaches to alleviate potential environmental stressors, develop automated and quantitative non-invasive methods to assess stress levels, and to communicate the approaches and methods developed to the poultry industry.

As our publications related to this goal are produced, we will include them on this page.
