About four years ago Scott Ertl was losing 10 to 20 cows a year, had low milk production and sick animals.
Ertl eventually found out it was from stray voltage. He was told he would have to stop dairy farming, something he did not want to do.
Instead he invented the Ertlizer, which deflects stray voltage from about 100 feet around the unit.
Since using the product he has only lost one to two cows a year and milk production has improved.
