Four milk cows dead by electrocution

Two dairy cows were found dead in their cubicles and a third was found lying dazed in a stall but the animal stood up 5 minutes later. Two days later; two other cows were found dead in the same row of cubicles. Death was due to electrocution caused by an electric wire in a steel pipe connected to front of the cubicles. Post-mortem findings supported this diagnosis.
