 floor is made of, ample bedding should be provided for 

 the comfort of the hogs. This bedding should be 

 changed often on account of vermin and disease

 whether portable or stationary, it is important to see that 

 proper drainage is secured. This is of special importance 

 in winter. Shelter for breeding swine should in par-

 house should never be located in a low place, but on a 

 rather high place, with ample slope. With poor drainage 

 there are apt to be worms and parasites through summer 

 and pneumonia and other diseases during the colder 

 months. 



Ventilation. — It is just as important to the health of 

 the hog that its house be provided with ample ventilation 

 as it is to our health that the air in our homes be changed 

 from time to time. Fortunately, it is rare that hog 

 houses are made too close, but such is sometimes the 

 case. Nearly all hog houses are so arranged that the 

 hogs can go in and out at will, the opening providing 

 ample ventilation for winter. In the summer, however, 

 some houses are inclined to heat very greatly, and in 

 such provision should be made at the top for ventilation. 

 Windows in the top of the house should be arranged to

 When a wooden floor is used in hog house construction, 

 provision should be made to have ventilation underneath 

 the floor to keep it dry.

 should be built to provide for ample sunlight. Plenty of
