or vice versa, or from sweet milk to sour milk, it is al- 

 most sure to cause trouble. Experimental data show that 

 sour skim milk is just as good as sweet skim milk, and 

 that butter milk is just as good as sour or sweet skim 

 milk, but if these various feeds are to be used they must 

 be used continuously and not alternately. 



Treatment. — The best way to handle scours of this 

 kind is not to allow the cause for them a chance to pre- 

 vail. Feed both the sow and the pigs as they should be 

 fed. If through accident a mistake is made and scours of 

 this kind are started, remove the cause as nearly as pos- 

 sible, and supply sanitary conditions as well as good feed. 

 If the scours result from over-feeding, the feed should be 

 reduced and at the same time the dam, in case the 

 pigs are sucking, or the pigs themselves after they are 

 weaned, should be given a physic and thoroughly cleaned 

 out. This should be followed by a small quantity of 

 good, wholesome easily digested feed, and the pens 

 should be thoroughly cleaned and disinfected. Better 

 still if the pigs are put into entirely new pens. 



Contagious Form. — The contagious form of scours is 

 usually called white scours. Sometimes the discharge 

 may also be black. The best cure for this trouble is the 

 same as given, namely, physic the animals thoroughly, 

 disinfect and clean up the troughs and pens and other 

 places occupied by the pigs so as to clean out all the 

 germs which are the cause of this trouble. As a physic 

 epsom salts, castor oil or linseed oil may be used.

This disease seems to be caused by improper nutrition. 

 It usually consists of paralysis of the hind quarters of the 

 hog so that it cannot stand on its hind feet, but drags it-
