Santoiuii, which was fornK^'iy widely iiscmI as a romcdy for worms in 

 hogs, is practically uiiobtainablo at tlic present time owing to foreign 

 trade conditions. 



The following treatment lias been found to be very effective in 

 expelling intestuial worms in experiments conducted by the Zoological 

 Division of the Bureau of Animal Industry: 



Withhold all feed and water for 24 hours, then give each pig from 

 1 to 2 ounces of castor oil to which has been added oil of American 

 wormseed as follows: Pigs weighing less than 50 pounds, one-half 

 teaspoonful; pigs weighing 50 to 100 pounds, one teaspoonful; large 

 hogs, 2 teaspoonfuls. Each pig should be dosed separately if the 

 best results are to be obtained. Castor oil should always be given 

 with oil of American wormseed. Other laxatives are not satis- 

 factory. 



DANGEROUS TO DRENCH HOGS. 



Drenching hogs is dangerous, as they are liable to get the remedy 

 into the lungs. With sufficient assistance pigs may be held, the 

 mouth kept open by means of a couple of loops of wire or rope, or 

 leather straps, and the medicine given in a tablespoon or a large 

 kitchen spoon. By this method, though it is troublesome, one may 

 be certain that each pig gets his proper dose. After dosing with . 

 the above mixture pigs may be fed and watered. Repeat the treat- 

 ment in 10 days. 



CHANGE PASTURES FREQUENTLY. 



Healthy hogs become infected with intestinal worms from feed, 

 water, and soil which have been infested by the droppings from 

 infected hogs. Frequent change of pasture is one of the best means 

 of reducing worm infestation to a minimum. Hogs,, however, 

 should not be allowed to run at large on open range, as this favors 

 the spread of hog cholera. 



Swine can be raised when they are confined m limited quarters if 

 the quarters are kept clean, but they will do much better and stay 

 in better health if they have plenty of pasture. Divide the pasture 

 into convenient areas, so that the hogs can be shifted from one pasture 

 to another. This not only provides fresh pasture, but affords an 

 opportunity to disinfect the pastures by plowing and reseeding or by 

 exposure to the sun and weather.
