History of Cast Iron Hog Oiler

Hog oilers were innovative agricultural tools popular in the late 19th and early 20th centuries. These devices allowed hogs to self-administer medicated oil by rubbing against them, helping to control external parasites like lice and mites. The design typically involved a reservoir for oil and a dispensing mechanism that would release oil onto the hog's skin when rubbed. They were a significant advancement in swine health and management before the widespread use of modern veterinary pharmaceuticals.
