The primary objective of this study was to determine the behavioral and physiological effects of tail banding and atrophy using rubber rings 2 to 4 mo before first parturition in dairy heifers either with or without the use of epidural anesthesia. The secondary objective was to determine behavioral responses to tail banding using rubber rings in calves 7 to 42 d of age. Preparturient heifers (n = 24) were randomly assigned to one of four treatment groups: 1) tails were cleaned and handled; 2) tails were cleaned, handled, and an elastrator band was applied to the tail; 3) an epidural was administered 15 min before cleaning and handling; and 4) an epidural was administered 15 min before application of an elastrator band. Behavioral observations and physiological responses were collected for 6 wk. Additionally, behavioral responses to tail banding were recorded for 10 d on Holstein heifer calves that were 1 to 6 wk of age (n = 40). No significant differences in behavior were observed among treatment groups of preparturient heifers at any time during the 6-wk observation period. Preweaned calves that were 21 to 42 d of age demonstrated significantly more restlessness after application of tail bands compared to younger calves or control calves of the same age. Plasma cortisol values of preparturient heifers remained within limits previously described for nonstressed animals and no significant differences were detected among groups. Hematological values remained within the reference values for cattle, and there were no significant differences between groups except for relatively more eosinophils in the heifers that received epidurals. No significant differences in heart rate or body temperature were detected among groups.
