A MANUAL ON THE HOG. 93 



times watery dark and offensive, and occasionally mixed 

 with blood. In the latter case there is often severe griping, 

 and occasionally the large gut protrudes. There is often a 

 cough, slight at first, but gradually increasing in severity 

 until it becomes distressing. At first it resembles the 

 wheezing, hacking cough occasioned by sleeping in the dust, 

 but as it progresses there is difficulty in breathing, heav-

 the hog grows gradually weaker, staggers when he walks,

 In some instances the mucous membrane of the nose is in-

 cannot be properly regarded as a necessary accompaniment 

 of the disease, though by burrowing into the flesh, they 

 greatly aggravate the suffering of the patient. 



PREVENTIVES. 



These properly embrace whatever will conduce to the 

 general health of the hog, and include proper feeding, care, 

 and the^use of certain disinfecting medicines, such as sul- 

 phur, tar or turpentine, salt, and alkalies. 



The food should be varied and natural, consisting of 

 grain, grass and roots. 



The care should be such as is entirely consistent with 

 recognized laws of health, as applied to swine. They 

 should be protected from violent changes of temperature, 

 so fruitful of disease, and especially of that class of dis-
