free from intestinal worms and by keeping their digestive tract in 

 good working condition. 



Santonin and calomel are perhaps the two most valuable 

 remedies that we possess for ridding hogs of intestinal worms. 

 These two drugs should be given in doses of about 5 gr. of san- 

 tonin and 8 gr. of calomel for each 100 pounds of live weight. 

 The best plan of giving these two drugs is in powdered form, 

 thoroughly mixed with the feed. 



Giving Worm Medicine. — In giving calomel and santonin to a 

 large drove of hogs it is usually a good idea to place all the animals 

 in a large pen at night without any supper and allow them to come 

 up the following morning good and hungry. Then, before any 

 other food is given, give the ground feed in which the medicinal 

 agents have been mixed. The most effective plan of giving worm 

 medicine is to have your local veterinarian put you up some pow- 

 ders, each containing enough of the two drugs to dose, say, about 

 five hogs. Mix this with a small amount of soaked ground corn or 

 bran and place in the feed trough. Then let out five of the ani- 

 mals and let them eat up the contents of the trough. These animals 

 should then be driven into another lot, and five more let out into 

 the feed lot. By this means of dosing only a few animals at a time 

 all the hogs get about an even amount of the drug, whereas, if the 

 entire amount was mixed with the feed of the entire herd, there 

 would be several of the less active animals which would not receive 

 a sufficiently large amount of the drug to do them any good. 

 Another important element in getting proper administration of this 

 drug consists in thoroughly mixing it with the food before giving it. 



Do not simply scatter it over the food after it has been placed 

 in the trough, but thoroughly stir it up with the ground feed in a 

 bucket or other vessel and see that it is most thoroughly scattered 

 through the entire contents of the vessel. It is only by thus 

 thoroughly mixing the drug with the food that good results can be 

 accomplished. 



Another remedy which is often used for the purpose of getting 

 rid of intestinal parasites in hogs is turpentine. This remedy has 

 the advantage of being cheap, and is usually convenient. It is 

 especially useful in treatment of worms if the so-called "thorn- 

 headed " worm, which is described in the section on Intestinal
