DISEASES OF SWINE 



GENERAL DISEASES 



DIAGNOSIS OR RECOGNITION OF DISEASE 



The diagnosis is based on a careful observation of 

 the symptoms or evidences of disease. This is not as 

 difficult in swine as it is in some of the other farm 

 animals, but unless we are acquainted with the be- 

 havior and habits of swine and possess a knowledge 

 of the normal function and appearance of the differ- 

 ent organs of the body, we cannot expect to recognize 

 disease. This is very essential, for without it we are 

 unable to recognize the true nature of the diseased 

 process, and cannot use an intelligent line of treat- 

 ment. Stockmen have plenty of opportunity to gain 

 this knowledge by practical experience and careful 

 observation. 



The general symptoms of disease are those affect- 

 ing the entire system. They inform us as to the con- 

 dition of the animal, at the outset and during the prog- 

 ress of the disease. Thus we have the symptoms 

 connected with the (o) pulse, {b) respirations, {c) 

 body temperature, (d) visible mucous membranes, 

 {e) surface of the body, (/) secretions and excre- 

 tions, and {g) nervous system.
