Occurrence of Vertical Fissure (Sand Crack) in a Holstein Heifer: A Case Report

Mohsen Nouri

The aim of the study reported here was to determine the clinical and morphopathological appearance of sever vertical fissure in a Holstein heifer. A 2.5 year old Holstein heifer was presented with lameness and abnormal weight bearing, for clinical evaluation in March 2010. The heifer was 7 months pregnant. The affected claw was more boxy than normal and the abaxial wall was convex in all directions. The solar surface of the affected claw was angled and bruised in zone 4. The lame cows used the heel region for weight bearing in standing and walking time. The heifer showed type 5 sand cracks. Based on the results the following conclusions were reached: (1) drinking water is analyzed for sulfate, iron, and nitrates, periodically, (2) Supplementing the diet of pregnant heifers in problem herds with biotin is recommended and (3) Management conditions such as poor drainage, accumulation of feces and urine on floors and overcrowding should be improved.
