Abstract
First order dynamics approaching of broiler chicken deep body temperature response to step changes in ambient temperature
Highlights
Physiological responses of animals to environmental stimuli provide a much-needed insight into how well chickens are coping with stressful conditions
Further studies are needed to more fully derive the model, this study provided a stepping-stone towards gaining a better understanding of the relationship between Deep body temperature (DBT) and ambient temperature (AT), taking us one step closer towards making optimal management and risk assessment decisions that are based on physiological needs of the chickens
Examination of DBT plots under the various AT test conditions revealed that DBT responses of each heat stressed chicken varied dynamically, predictably, and measurably as a response to AT pulses
Summary
Physiological responses of animals to environmental stimuli provide a much-needed insight into how well chickens are coping with stressful conditions Modeling such responses presents an invaluable tool for predicting behavior to environmental stimuli, informing management and risk assessment decisions, but it offers a unique opportunity to design model-based environmental controllers that respond directly to real-time physiological needs of the chickens. Vol 10 No. research opportunities in environmental control of confined animal housing systems through what they referred to as precision livestock farming. This term was used to imply that the use of continuous and automatic monitoring of physiological behavior among other things, contributes to more precise assessment and management of the animals’ wellbeing. Model-based control schemes often require compact mathematical models to predict the dynamic process response to the controller[8]
