Excerpt from Stomach Worms in Sheep: Prevention and Treatment For lambs under 1 year of age 1% ounces (50 cubic centimeters). For sheep past 1 year old 3% ounces (100 cubic centimeters). A glass with marks scratched on the side with a file may be used for measuring the doses. The drenching apparatus consists of (1) a strong rubber tube about 3 feet long and three-eighths inch in diameter; (2) a hard rubber, porcelain, or enamel-ware funnel, which is fastened to one end of the tube; and (3) a brass mouthpiece three-eighths inch in diameter and 9 inches long, fastened to the other end. It is preferable that the end of this tube should be closed and holes made in the sides of about the last two inches of its length. Ordinarily the treatment is given after the sheep have been without feed overnight, but apparently it may be given with equally good results without preliminary fasting, provided the animals are not gorged with feed or water when treated. For best results sheep should not be watered for 2 hours afterwards. While being drenched the sheep should remain on all 4 legs with its head held horizontally. This is important, for if the head is held above the horizontal (nose higher than the eyes), there is danger that some of the fluid will pass into the lungs, thereby causing pneumonia and almost certain death. Measure the dose in the measuring glass, and after the drenching tube is in position pour the dose slowly into the funnel. The metal mouthpiece of the drenching tube should be placed between the jaws in the space between the teeth at the side of the mouth and directed backward, but should not reach farther than the base of the tongue. In order to prevent the sheep from stepping up the end of the mouthpiece with its tongue and thus interfering with the flow of the liquid, the person holding the mouthpiece in the sheep's mouth should give it a rotary motion. This tends to keep the sheep swallowing, prevents plugging the tube, and also tends to keep the fluid from entering the lungs. The fluid should not be administered more rapidly than the sheep can swallow comfortably. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
