No. 4.] CATTLE COMMISSIONERS' REPORT. 561 



This medicine ma}' also be used as a preventive of these dis- 

 eases, and for this purpose sliould be put in the feed of the whole 

 herd. Care should of course be observed to see that each animal 

 receives its proper share. The animals should be kept dry and 

 comfortable, and where draughts of air will not blow upon them. 

 The food must be such as can be digested by the irritated and 

 inflamed organs. 



When the hogs are first found to l)e affected, the lot or the pens 

 should be disinfected by dusting plentifully with di"y, air-slaked 

 lime, or by sprinkling with a five per cent, solution of crude car- 

 bolic acid. The animals should then be all removed to new 

 quarters. If possible, the sick and apparently well should be 

 separated before the}' are moved, and then put into dift"erent lots. 

 The hogs should be kept in dry lots or pens, where there is no 

 mud, and, above all, no stagnant water. It is well to keep these 

 lots disinfected by the free use of air-slaked lime or carbolic acid. 



If any hogs die during the progress of the outbreak, their car- 

 casses should be immediately burned or deeply buried, and the 

 places where the}* have lain, or the ground over which they are 

 dragged, should he disinfected with carbolic acid or lime, accord- 

 ing to the method already mentioned. 



When these diseases appear upon a neighboring farm, precautions 

 should be adopted to prevent the introduction of the contagion. 

 No one should go upon the fields or into the pens where the sick 

 animals are, and then go into another farm where the disease has 

 not appeared. Remember that a particle of manure or dirt the 

 size of a mustard-seed from an infected farm is sufficient to start 

 an outbreak that will destroy a herd of swine. A particle of that 

 size may be carried upon the shoes of a visitor, upon the foot of a 

 dog or other animal, upon a wagon wheel or in a multitude of other 

 ways. Non-intercourse at such times is, therefore, the safest rule. 

 It is advisable, when there is reason to fear this disease, to keep 

 the hogs in a small enclosure, which should be as dry as possible, 

 and disinfected once a week with air-slaked lime or a five per cent, 

 solution of carbolic acid. A small quantity of carbolic acid (three 

 to fifteen drops, according to age) in the drinking water tends to 

 prevent infection, and may have a beneficial influence upon the 

 course of the disease. 



Hog cholera has been reported to the Board during the 

 year as follows : —
