474 HORSE, SWINE AND POULTRY DISEASES 



mals further up the stream ; the introduction of purchased hogs on to 

 a farm without proper investigation as to the health of the herd from 

 which they came. The first two of these causes of infection might be 

 diminished greatly by common action of the community which is 

 threatened by merely enforcing the laws which already exist on the 

 statute book but which are now entirely disregarded.. The third is, 

 of course, entirely within the control of each individual concerned. 

 (Ark. B. 67.) 



Management of Cholera Herds. Immediately disinfect the prem- 

 ises thoroughly. Separate the well hogs from the sick ones, and di- 

 vide the healthy animals in two or more groups, and isolate them as 

 completely as is possible. All carcasses of hogs which have died from 

 cholera should be burned or buried deeply and covered with quick- 

 lime. As the germs of cholera gain access to the system through 

 feeding, the way of prevention is well marked. All feeding troughs 

 and utensils should be thoroughly cleaned and fumigated, the yards 

 plowed and preferably planted with a forage crop in season. Feed 

 sparingly, using a laxative, easily digested and nourishing ration. 

 When hog cholera serum is used, the hogs treated should remain to- 

 gether in the infected yards. The possible introduction of the dis- 

 ease into the pens by people, dogs, birds, etc., should be guarded 

 against, especially if hog cholera is in the neighborhood. Whenever 

 it is necessary for a person to enter a hog lot when the disease is pres- 

 ent, the shoes should be thoroughly cleaned and disinfected. Per- 

 sons taking care of diseased animals should take necessary measures 

 to prevent the spread of the disease, and see that others take similar 

 precautions. (N. J. L. S. C. Cir. 1.) 



When several hogs die within a short time, it may be safely as- 

 sumed that the cause is due either to hog cholera or swine plague, or 

 both diseases at the same time, and the following instructions should 

 be closely followed: Report the matter at once to the State Veterina- 

 rians ; bury or burn at once all hogs which have died of any disease ; 

 confine the hogs to enclosures removed from the public highway; 

 disinfect hog pens and enclosures by sprinkling with the following 

 solution: Carbolic acid, crude, 1 Ib. to five gallons of water, or air- 

 slacked lime instead may be used daily ; hogs should be kept in dry 

 pens ; dogs must be tied up, as they carry the disease ; wagons or hog 

 racks used to remove dead hogs must not be taken on a neighbor's 

 farm ; only the one whose duty it is to feed the animals should be 

 allowed near the pens, this attendant to keep away from neighbors' 

 hogs. As preventative measures when the disease exists in the neigh- 

 borhood the following precautions should be observed : Do not visit 

 your neighbors' hog pens or enclosures, nor allow any unauthorized 

 person to go into your own hog pens or enclosures; keep your dog 

 tied up; do not allow your hogs to run, but keep them in small 

 dry pens or enclosures. (N. D. B. 83.) 



HOW TO DISINFECT. 



There is no place on the farm where disinfectants are more 

 useful than in hog houses or yards. Whitewash ; air slacked lime ; 

 chloride of lime; stock dips; compounds of creosote; crude carbolic
