Low-level electrical current, commonly known to farmers as 'stray voltage', can impact Iowa's dairy cows and other livestock, reducing milk production and affecting animal behavior.

The Iowa Stray Voltage Guide was developed to improve communication and solve problems.

Sponsored by the Iowa Association of Electric Cooperatives, Alliant Energy, the Iowa State Dairy Association and Iowa Farm Bureau, the Iowa Stray Voltage Guide is a tool to help farmers who are concerned about whether their animals are experiencing stray voltage issues. It provides standard procedures for testing for stray voltage and identifies common causes of stray voltage.
