100 PRACTICE OF EQUINE MEDICINE. 



What is the prognosis ? 



The disease itself is not fatal, as a rule, but is apt to produce 

 an unsound animal or leave the animal in such condition as to 

 render it liable to other affections. Complications may arise which 

 may make the prognosis grave. 



Deformities may result, varying in extent, which may or may 

 not interfere with the usefulness of the animal. 



Outline the treatment. 



A laxative or purgative is usually required at the onset, to 

 rid the alimentary canal of the undigested material which is usually 

 present; in these cases linseed oil combined with sodium or potas- 

 sium bicarbonate, in the form of an emulsion, can be employed. 



Then cod-liver oil with preparations of iron or lime-water, 

 given three times a day if the stomach does not rebel. 



A drachm or so of prepared bone-dust given in the food. 



Quinine in tonic doses is often useful. Fowler's solution of 

 arsenic, nux vomica, pepsin, pancreatin, etc., may be used in cases 

 indicated. 



Pure air, exercise, and good food are important. The food 

 should consist of the mother's milk, if possible. In other cases, 

 cows' milk, to which lime has been added to aid its digestion. 



To prevent this disease, feed pregnant animals properly, and 

 in this way lessen or prevent the disease. 



If there is any deformity, it should be corrected by the use 

 of padded splints; the inflamed parts that are painful can be bathed 

 with anodyne liniments, after which stimulating liniments are of 

 service. 



OSTEOPOEOSIS. 



Name the synonyms. 



Big-head; eccentric atrophy of bone. 



Give the definition. 



This is a porous condition of the bone, characterized by an 

 enlargement of them due to a dilatation of the Haversian canals, 

 with atrophy or absorption of the compact bony substance. 



What is the causation ? 



This is very common among the equines in certain districts, 

 and may be seen among high-bred horses as well as common-bred 

 work horses.
