Animals are a lot more sensitive to things as are we.... To say voltage - much more so, and they don't wear boots.
Found some interesting sites on this...
this is from one of them
~installation of an equipotential plane and voltage ramp is highly recommended. An equipotential plane is created when the reinforcing steel in the concrete floor is electrically bonded to all metal equipment~
And a possibly interesting
book , with possibly some good advise on equipotential planes suitable for the purpose for those who work around farms...
FYI I am not one of them.... But would suggest the use of a very sensitive meter for checking point to point contact. A wiggy won't cut it. But as suggested by that page about cows - maybe they just don't like or trust the new fangled heated water thingy.
