 problem in swine feeding is to supply sufficient nutritive material for 

 building and repairing the body and furnishing sufficient energy to 

 lay on fat. The most satisfactory ration must necessarily be made 

 up of feeds wliich are wholesome, relished by the hog^ and at the

 mixture of charcoal, ashes, lime, salt, sulphur, and copperas kept 

 where the hogs can eat it will tend to prevent worm infestation.
