Apparatus for aspirating and irrigating the rumen of a cow includes a nozzle connected to one end of a flexible tube and adapted to be slid down the cow's throat and inserted into the rumen. The other end of the tube is connected to a container which is adapted to be placed in a vacuumized condition by a hand-operated suction pump. When the pump is operated, toxic liquid and food in the cow's rumen is sucked into the nozzle, through the tube and into the container. A second tube is located in the first tube and is adapted to eject a spray of water for cleaning the nozzle and for irrigating the rumen. The water is contained in a tank which may be pressurized by compressed air at a veterinarian's office.
