Therefore, understanding the impact of thermal stress on animal welfare, productivity, and behavior has become crucial to support sustainability in livestock production. Different behaviors can be associated with suboptimal thermal changes in an animal’s environment, which is why the objective of this study is to use precision livestock farming techniques and technologies to collect behavioral activity and physiological measures of pig outcomes under different thermal conditions. A total of 144 feeder pigs will be housed in two rooms. Each room has 12 pens with six pigs per pen. Pigs will be exposed to thermoneutral conditions, as well as moderate heat and cold stress every week. Each thermal condition will be applied for two consecutive observation days. Each room will have its own data acquisition system and sensors will be installed to continuously monitor environmental conditions, including temperature and relative humidity. Additionally, concentrations of gases such as carbon dioxide and ammonia will be measured. Water flow meters will be placed in every pen to measure pen-level water usage. Pig surface temperature will be monitored with a thermal camera. An RGB+IR camera mounted above each pen will collect images to be labeled for detecting lying lateral, lying sternal, sitting, and standing postures, maintenance behaviors, and activities. Changes in behavior budgets will be compared across pens, thermal conditions, and pig age. Data analysis will focus on evaluating the relationships between thermal conditions and both behavioral and physiological changes. Results are expected to provide insights for enhancing animal productivity and welfare in a controlled environment. A deeper understanding of animal behavior will guide the industry toward optimizing swine production and indoor environmental conditions.}, journal={Journal of Animal Science}, author={Suazo, Isaac and Xiang, Lirong and wang-li, Lingjuan and Johnson, Anna K and Leonard, Suzanne M}, year={2025}, month={May}, pages={37–38} }
