Interpretive Summary:

Technical Abstract: Individuals in most animal groups exhibit consistent behavioral differences within or across situations (feeding, mating, predator avoidance, etc.) known as behavioral syndromes (Sih et al. 2004). Proactive (more nervous) vs. reactive (calmer) behavioral syndromes have been observed in many animal species and have been shown to influence how individuals cope with stress (Koolhaas et al. 1999). We investigated the relationships between stress coping styles, patterns of rangeland use, and performance of thirty six 3-year-old cows during two consecutive calving seasons (2006-07). We found that calmer cows (classified as reactive) spent more time at water, explored smaller areas in any given day, had lower body weights, longer postpartum anestrous periods, and weaned lighter calves than cows classified as proactive (more nervous cows). Because our results are based on a limited number of animals which belong to a fairly docile herd, they should be considered preliminary. Further work investigating these relationships is underway.
