Assessing stress or, conversely, the state of well-being, is an active area of research. Presently, production traits, health, and reproduc-tive variables continue to be the most readily measurable and practical indicators of well-being (Curtis, 1983; Fraser and Broom, 1990; Mader, 2010). In sheep, some indicators of stress might include:
