PREVENTION BETTER THAN CURE 49 



"Paper Skin" is the old name for the white, "papery" ap- 

 pearance of the skin of sheep suffering from stomach worms. 



Prevention is the best cure. If the farm is fenced so the ewes 

 and lambs can be changed to an entirely fresh pasture every 

 two weeks until the lambs are sold, or weaned and turned into 

 stubble or cornfields, there will be little danger from worms. 



Tobacco Prevents Stomach Worms 



Tobacco dust or stems chopped fine and placed where sheep 

 and lambs can always have access to them will help prevent 

 stomach worms. Instances have been reported where lambs 

 that have had tobacco stems to eat remained healthy all summer 

 on old pasture. There are worm powders and medicated salts 

 on the market for which claims are made. Keeping tobacco 

 stems before sheep the year round is a cheap and apparently 

 effective preventive, but by all means arrange changes of pasture. 



Drenching the Only Cure 



It has never been shown that sheep will eat enough of any- 

 thing to "cure" stomach worms. Anything that can be fed to 

 them can be considered only as a preventive. 



Drenching is the only cure when once the worms have posses- 

 sion and the sheep are losing flesh. 



Here are three good treatments for stomach worms: 



Blue Vitriol 



Dissolve one ounce of blue vitriol in one gallon of water. Do 

 this by putting the vitriol in a sack and hanging it in the water 

 it will not dissolve in the bottom of a vessel. Give this mix- 

 ture in doses of from two ounces for lambs to three ounces for older
