Stomach Worms in Sheep. 5 



The doses for lambs and sheep are : 



For lambs under 1 year of age If ouncea (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 stopping 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. 



Care in the administration of the dose is highly important, as 

 carelessness or any undue haste is liable to have serious results. 

 The copper-sulphate treatment, like the administration of medicines 

 in general, is safest in the hands of a competent veterinarian. 



CHANGE OF PASTURE NECESSARY FOR BEST RESULTS. 



Although losses from stomach worms in many cases may be 

 minimized by repeated medicinal treatment without change of 

 pasture, much better results can be obtained if the treated animals 

 are placed on ground that is free or practically free from infection. 

 It is still better to institute preventive measures before the results 

 of stomach-worm infection become evident. A lamb that has been
