to the health of hogs. It is very seldom that a floor of 

 dirt is kept free of filth. Much of the bronchitis, pneu- 

 monia, rheumatism, and pig scours can be prevented by 

 avoiding these insanitary conditions. 



If the site selected for the buildings and yards does not 

 have sufficient surface drainage, grading and tiling the 

 yards may correct this condition. It is advisable to 

 arrange the lots so that any one of them can be plowed, 

 and sowed to rape, rye, or other forage crops. This is 

 the most effective method of cleaning hog lots that have 

 been used continuously. Manure, corn-cobs, and other 

 litter should not be allowed to accumulate in the hog- 

 houses and yards. The yards should be cleaned by 

 raking or scraping the litter into piles. The litter may be 

 burned or scattered over a field and later plowed under. 

 Small yards may be covered with lime after they have 

 been thoroughly cleaned. 



The two most important sanitary featiu-es to consider 

 when building a hog-house are the windows and floors. 

 Sunlight and well-ventilated quarters are necessary to 

 the health of animals. Unless the floor is made of a 

 material that does not readily take up the filth, it cannot 

 be kept clean. The windows should be so placed as to 

 permit sunlight to reach all parts of the floor, and venti- 

 late the building without causing drafts to strike the hogs 

 while they are lying on their beds. 



Hogs should not be given feed on the groimd, especially 

 if the yard is muddy. If hand-feeding is practiced, a 

 concrete feeding-floor amply large to accommodate the 

 herd should be provided. The feeding-floor should be 

 cleaned daily, and frequently sprinkled with a disinfec- 

 tant . If garbage is fed, the floor should be cleaned, washed, 

 and disinfected daily. When hogs are given wide range.
