intestine^ often hidden in the folds of the lining membrane. It is a very common 

 parasite of swine, and does not seem to cause much inconvenience to the animal. 



Whip- Worm. — This is also a small worm, being about one and one-half 

 inches long. It attaches its head to the lining of the intestine, and is usually 

 found in the beginning of the large intestine. The anterior portion is very thin 

 and hairlike, and the posterior portion is thick and cylindrical in shape. Like 

 .the pin-worm, it does not seem to create much disturbance, but must be more or 

 less injurious. 



Treatment for Intestinal Worms. — Preventive treatment consists in 

 keeping buildings and surroundings clean and sanitary. Feeding in filthy yards 

 and allowing to drink stagnant water are practices which favor the spread of 

 parasites. 



As to medicinal treatment, the writer has found that allowing hogs to have 

 access to a mixture of charcoal and salt, or charcoal, wood ashes, and salt, seems to 

 be quite effective in driving out round worms. 



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, sometimes 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 cougl-: 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 squeezing 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. Plough- 

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



Other Diseases. 



The diseases which have been mentioned represent only a few of the troubles 

 which may affect the hog, and no attempt has been made to treat the subject fi'om 

 a veterinarian's standpoint. There are other diseases. The aim has been to note 

 only a few simple remedies for common ailments, rather than the cure of disease. 

 The hog is not easy, to treat for disease, and the main effort of the farmer should 

 be towards maintaining health and preventing the entrance of disease into his 

 herd. In regard to the long list of diseases which have not been mentioned, 

 together with many of those included in the list, it will generally be advisable to
