Stress Factors of Farm Animals and Their Effects on Performance
Department of Biosystems and Agricultural Engineering
Stressful environments are a major contributor to animal discomfort. This project is developing improved means of animal stress measurement methods.
Two objectives guide Kentucky's contributions and partnerships in this Multi-State Project:
A.Identify appropriate measures of animal stress and well-being and characterize factors affecting the biology of the stress response.
B.Evaluate management strategies that minimize the detrimental effects of animal stress.
An improved understanding of horse thermoregulatory response during road transport is important for enhancing animal welfare, improving trailer design characteristics and to develop better means of measurement of animal thermal status. The method developed to determine bird behavior during normal and stressful events is a useful improvement over tedious video recording analyses, the current standard method for quantifying animal behavior.
