Keenan is a world leader in ruminant Nutrition and the technology of optimum feeding for livestock. The evolution of the Keenan System began in the 1960's when Irish farmer, engineer and innovator, Richard Keenan Senior, began to trace the development of TMR feeding and mixer wagon design. The Keenan Mixer Wagon has continually developed and evolved from the orginal Easi-feeder to today's Mech-fiber range. Nutrition support commenced in the 1980's and has advanced to the new RUMANS Nutrition approach, based around the capabilities of the Mixer Wagon. Today, over 25,000 producers worldwide use Keenan to support their feeding and production systems.
