Abstract / Zusammenfassung

OBJECTIVES: This randomized clinical trial will evaluate the effect of bandaging on healing uncomplicated Sole ulcers (SU).
MATERIAL AND METHODS: This study included Holstein Friesian dairy cows (n=52), diagnosed with uncomplicated SU (n=56) upon the first examination (week 0). All hoofs were cleaned and trimmed by a professional hoof trimmer or a veterinarian. Afterwards a wooden block was applied on the sound claw. 15 g of an iodine ointment was applied on each SU. Cows were then randomly assigned into either a non-bandaged (n=32, Group 1) or bandaged group (n=24, Group 2). The bandaging process was standardized and applied by the same veterinarian for all groups. The process of wound healing was scored weekly (weeks 0, 1, 2, 3, 4) according to a visual inspection scheme. Photographs of lesions were taken and a special software package (Jalomed®), was used to track changes in lesion size across observations. The healthy formed corium was judged as full recovery. Locomotion was also evaluated and scored weekly (Sprecher et al., 1997). If an ulcer was not considered healed, the whole procedure was repeated until the end of week 4.
RESULTS: In total 19 of 32 sole ulcers (59.4%) in the non-bandaged group were healed at week 4 compared to 7 of 24 ulcers (29.2%) in the bandaged group. The log-rank test indicated that healing was significantly higher for non-bandaged than bandaged SU's (p = 0.024). A Wilcoxon Rank Sums Test indicated that bandaging had no effect on locomotion (p = 0.9). However, cows with a healthier locomotion (Sprecher 1+2) had significantly smaller lesion sizes (median lesion size, 0.5 cm², IQR=0.21-0.92 cm²) than animals with locomotion score 3-5 (median lesion size, 0.9 cm², IQR=0.42-1.81 cm²; P<0.001).
CONCLUSIONS: Results suggest that bandaging has a negative effect on the healing process of SU's. Healing of sole ulcers might only require hoof trimming and a wooden block.
