Stomach Worms in Sheep. 5 
The doses for lambs and sheep are: 
For lambs under 1 year of age.............2.....- 1? ounces (50 cubic centimeters). 
Korisheep past: Luyear old s22 422 20. ona eS eetiee.e 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 (8) 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
