Oops,sorry forgot the links, check it out yourself. I also forgot to mention that animals can be sensitive to ground differentials as small as 0.5 to 1 volt depending upon conditions.
This engineer testifies under oath citing research performed by Doug Reinmann at University of Wisconsin stating those same facts.
Doctor Reinmann's research paper can be found here (pdf reader required for some links) http://www.uwex.edu/uwmril/stray_voltage/s vmain.ht m http://www.strayvoltage.org/stories/index.php3? Sto ry=20010221_utility.inc
Growing up on a farm, I have learned of the negative effects "stray voltages" cause to farm animals.
This is often linked to the power return to the station. Everywhere, electrical service has everything connected in relation to ground, with any difference in the power balance of the phases of power taking a different path back to the source of the power, i.e. the ground itself, and potentially through anything in its path.
This "stray voltage" manifests itself when animals, with 4 bare hooves, paws, etc. touching the ground, detect small but irritating (to varying degrees) levels of current taking an alternate path back to the source. Animals have also been proven to have a higher sensitivity for detecting stray currents as well, compared to humans.
Often in cases, to the power companies defense, they will come out to do a check on the premises, and often do find a problem in the local, on-farm wiring, potentially causing the problem.
Unfortunately, in the cases of newer farms where all the wiring is new and up-to-code, a stray current is often traced to off-the-farm sources, for example, a newly-installed High-voltage Power Line.
