1. The method of drenching ruminants and other animals comprising:
- a. selecting a speculum which has an end estimated to be larger than the animal'"'"''"'"'s larynx, but smaller than its esophagus, b. inserting the selected speculum through the mouth and into the esophagus of the animal, c. extending a flexible stomach tube through the speculum into the esophagus past the thorasic inlet of the animal, d. pumping liquids through the stomach tube into the stomach, and e. withdrawing the stomach tube and speculum.

Abstract
To drench a calf, a tubular esophageal speculum is inserted through the mouth of the calf into the esophagus. The speculum has a knob on the end which will enter the esophagus, but is larger than the larynx so it will not enter the larynx and it also will not pass the thorasic inlet. With the esophageal speculum safely in the esophagus, a flexible tube in extended from the end of the speculum into the rumen and the fluid pumped therethrough, thus accomplishing the direct rumen drenching process.
