in yards set off for this purpose. These yards should be 

 cleaned and disinfected after each shipment. All shipped- 

 in hogs should be vaccinated by the double method, and 

 quarantined for at least three weeks. 



If the houses and yards can be cleaned and disinfected 

 and their location does not endanger other herds, the sick 

 animals should not be moved to new quarters. If the 

 houses are old and poorly constructed and the yards 

 covered with such litter as corn-cobs, manure piles, and 

 old straw stacks, it is advisable to provide more comfort- 

 able and sanitary quarters. When the weather is warm, 

 a low shed large enough to accommodate all of the hogs 

 and an open field are best. This furnishes protection 

 from the sun and a clean range. Clean, roomy, dry, and 

 well-ventilated sleeping quarters, free from drafts, and well- 

 drained yards are best when the weather is cool and wet. 



A very light ration should be given. It is not advis- 

 able to feed kitchen slops, skim-milk, or buttermilk. 

 Intestinal antiseptics should be used. Sulfocarbolate 

 tablets, or copper sulfate may be given with the drinking 

 water or slop. If copper sulfate is used as an intestinal 

 antiseptic, 4 ounces may be dissolved in 1 gallon of drink- 

 ing water, and 1 quart of this stock solution should be 

 added to each 10 gallons of water or slop. The troughs 

 should be disinfected and turned bottom up after water- 

 ing or feeding the animals. This method of feeding 

 should be practiced as soon as symptoms of cholera de- 

 velop, and continued for at least one week after recovery. 



The first step in disinfecting hog-houses and yards is 

 thoroughly to clean the walls, floors, and yards. Dust 

 and dirt should be brushed or scraped from the walls 

 and floors. If the floor is earth, the surface should be 

 removed to a depth of several inches and covered with
