COMMON DISEASES OF SWINE 313 



Turpentine is commonly recommended for worms, especially 

 the thorn-headed worm. The dose is a teaspoonful for every 

 eighty or one hundred pounds live weight of the hogs to be 

 treated. It can be given in the feed, and the hogs should be 

 fasted at least twelve hours before treatment. A dose each day 

 for three days will generally prove effective. 



Another remedy which is recommended is five grains of 

 calomel and eight grains of santonin for every hundred pounds 

 live weight of the hogs. This remedy can also be given in the 

 feed. It is generally advisable to give a physic after treatment 

 for worms. 



LUNG WORMS. 



The lung worm is a small, thread-like, whitish worm, some- 

 times found in large numbers in the air-passages of the lungs. 

 Ordinarily, about the only symptom is a spasmodic cough, 

 which is somewhat similar to the cough which accompanies 

 bronchitis. Sometimes the irritation caused by the worms 

 produces inflammation and consolidation of the lung tissue, 

 in which case the animal dies, but in many cases no bad effect 

 is apparent. In a post-mortem examination, the worms can 

 be detected by cutting the lung near the apex and then squeez- 

 ing the tissue next to the cut. The pressure forces the thread- 

 like worms out upon the cut surface. 



There is practically no effective treatment for this parasite. 

 Clean pens, in which disinfectants are liberally used, and clean, 

 well-drained yards will help keep the worm in check. Filthy 

 yards and wallows favor its development. Ploughing up old 

 hog lots and re-seeding them is also a preventive measure.

The diseases which have been mentioned represent only a
