| Abstract | ||
| This study was carried out in the Winter of the year 2007 in a dairy herd at the vicinity of Tehran (Eslamshahr). Measurements were performed on 18 Holstein cows during first-lactation. Five Holstein dairy cattle were randomly selected and clinically studied, too. Length of the claw’s dorsal flexure was measured with a ruler and also the hooves trimmed in the toe vertically for measuring of the white line height. In each case, the Lesions of the hoof horn associated with hemorrhage and erosion of the solar surface were recorded and were illustrated their geographical distribution.In the heifers, positive correlation was seen between Length of the claw’s dorsal flexure and thickness of sole horn (p<0.05). Fifty-five perpercent of feet with thin soles had pathological claw horn lesions including sole hemorrhage that were located on the claw’s different regions. The most of lesion of solar surface have seen on the typical site of sole ulcer, white line zone and heel zone. Results showed that thin sole can initiated significantly more pathologic finding as compared to the normal hoof claws. In additions, concrete walking surface, commingling of animals and prolonged water contact of the claw horn have found aggravating factors in this dairy herd. | ||
