Livestock Oilers

“Scratches them where they itch; oils them where they scratch!”

The Rol-Oyl Story

The Rol-Oyl Story
In 1959, the United States cattle industry lost over $800 million because of insects! Effective insecticides were available and ready to use, but there was no way to effectively administer the insecticide to the cattle for continuous protection. A survey was conducted among livestock producers to find out what features they wanted in a livestock oiler. Overwhelmingly, these producers asked for an oiler that would stand up to heavy use by all kinds of livestock, that would allow the livestock to evenly distribute the chemical, and that would require minimal labor. Each feature, each problem area was thoroughly researched and tested. In 1960 after one year of intensive testing, re-testing and proving, the Rol-Oyler was perfected according to specifications defined by the leading livestock producers in this country.
