摘要: Production and behavioral measures were recorded to determine the level of stress pain associated with tail docking adult dairy cows a rubber ring. The possible advantages using an epidural anesthetic also examined. Sixty-four lactating, mixed-parity, Holstein randomly assigned one four treatment groups. treatments ring (RRA), without (RR), control (CA), (C). Behavior was examined on d 0, +1, +2, +6. Milk production feed intake monitored. Cows exhibited subtle changes following application rings, as well after administration 0 amputation After RR, RRA, CA groups displayed less shaking than C group. RR RRA continued exhibit Also held their tails in raised position +6, spent longer pressed bodies No significant differences milk or found. Results suggest that tail-docking cattle rings causes, at most, mild discomfort there is no benefit anesthetic. However, long-term effects need be investigated.
