To a cow standing in mud sticking a tongue in a waterer with 2 volts is like sticking your finger in a light socket. They quick drinking.
Cures are difficult when the power company things wrongly that 1.5 volts is good enough.
Classic cure is to bury a ground screen connected to the safety ground so the cow is standing in mud at the same voltage as the waterer. But its hard to train the cow to jump over the edge of that ground screen unless it tapers down deep into the ground for 20 feet at the edge.
The low voltage often comes from the power system ground connected to the local ground. A more effective scheme not liked by power companies is to break that primary to secondary ground connection. That puts the insulation in the distribution transformer in jeopardy when lightning hits the power line, so power companies want to put a surge protector across the ground wire gap to get the use of more grounds on the customer property.
I've seen such stray voltages put cattle or dairy operations out of business.
When it comes from the power line ground, its hard to cure without going off line.
