To compare the effectiveness of three treatments for sole injuries in dairy cows and to evaluate the ease and speed of applying the treatments.
A randomised clinical trial.
The three forms of treatment were elevating the affected claw of a lame cow with a wooden block glued to the unaffected claw (39 cows), elevating the affected claw with a rubberised shoe glued to the unaffected claw (42 cows) or applying a padded bandage to the whole foot of a lame cow (31 cows).
The percentages of cows that recovered from lameness at 3 and 7 days after treatment were significantly higher for cows treated with wooden blocks (P = 0.013 and P = 0.008) or rubberised shoes (P = 0.026 and P = 0.0003) than padded bandages. Cows treated with blocks had a recovery rate of 48.7% at day three and 65.8% at day seven, and cows treated with rubberised shoes, rates of 45.2% and 76.2%, respectively. Cows which had a bandage applied to the foot had recovery rates of 19.4% at day three and 32.3% at day seven. However, by day 14, there was no significant difference in recovery rate between the three treatments. Rubberised shoes were shown to offer a number of advantages over wooden blocks. The shoes were significantly quicker to attach than blocks (median of 9.5 minutes compared with 14.0 minutes, P < 0.0001) and remained on the claw longer (57.1% of rubberised shoes remained at 30 days compared to 30.8% of blocks, P = 0.025). The rubberised shoes also offered an advantage over wooden blocks for operator safety and health by reducing contact between the potentially hazardous adhesive used to attach both devices and the skin of the person applying the device.
Rubberised shoes are a superior method of elevating an affected claw in conditions of lameness likely to respond to removal of weightbearing forces.
比较三种治疗奶牛蹄部损伤的方法的有效性，并评估实施这些治疗方法的难易程度和速度。
一项随机临床试验。
三种治疗形式分别为：用胶水将木块粘在未患病的蹄爪上抬高患病奶牛的患病蹄爪（39头奶牛）；用胶水将橡胶蹄套粘在未患病的蹄爪上抬高患病蹄爪（42头奶牛）；给患病奶牛的整个蹄子缠上带衬垫的绷带（31头奶牛）。
用木块（P = 0.013和P = 0.008）或橡胶蹄套（P = 0.026和P = 0.0003）治疗的奶牛在治疗后3天和7天从跛行中恢复的百分比显著高于用带衬垫绷带治疗的奶牛。用木块治疗的奶牛在第3天的恢复率为48.7%，在第7天为65.8%，用橡胶蹄套治疗的奶牛恢复率分别为45.2%和76.2%。蹄子缠绷带的奶牛在第3天的恢复率为19.4%，在第7天为32.3%。然而，到第14天，三种治疗方法在恢复率上没有显著差异。橡胶蹄套相对于木块显示出许多优势。橡胶蹄套比木块附着得明显更快（中位数为9.5分钟，而木块为14.0分钟，P < 0.0001），并且在蹄爪上保留的时间更长（30天时，57.1%的橡胶蹄套仍在，而木块为30.8%，P = 0.025）。橡胶蹄套在操作人员的安全和健康方面也比木块更具优势，因为它减少了用于固定这两种装置的潜在危险粘合剂与安装装置的人员皮肤之间的接触。
在可能因去除负重力量而恢复的跛行情况下，橡胶蹄套是抬高患病蹄爪的一种更优方法。
