Hi Roy:

Having worked with stray voltage on dairy farms in the U.S. for about 15
years, it is interesting that the effects observed in the dairy herd on
this Bavarian farm are identical to the effects in dairy herds in stray
voltage farms.  Although transmitting towers have also been associated the
stray voltage problems in the U.S., the most common association is with
electric current from the distribution neutral reaching the cows by means
of earth paths.  Calcium loss is also a common problem for cows when
exposed to power frequency current present in the ground.  Since calcium
is an ion in the body, it might also be driven by direct currents.  Direct
currents arise in the environment from a number of sources, one of which
is the rectification of alternating current both in the earth and in
living organisms.  Alternating currents of power frequencies and other
frequencies are present in living organisms both because of induction from
magnetic fields and because the earth to which everything is connected is
used as one terminal of the entire electrical distribution system.  

Thank you.
