110 PRACTICE OF EQUINE MEDICINE. 



fracture of the bones of the hind extremity or of the pelvis is the 

 result. The pelvis is apt to break down when the foetus is present. 

 Fracture of ribs may take place. 



What is the prognosis? 



The prognosis is favorable if seen early and the proper kind 

 of food is given. If the disease is allowed to go on, the animal 

 dies of asthenia. 



Roloff says that these fractures get well by the formation of 

 a callous, while others say a union rarely takes place; false joints 

 are formed. 



The fractures in these instances are painless. 



What is the treatment ? 



Remove the cause, which is, in many cases, the lack of proper 

 food; in these instances it is well to change the pasture and supply 

 those articles that are wanting. 



Give ground phosphates (bone dust), one or two ounces two 

 or three times a day, and along with this a little common salt. 



Stop the milking and allow the animal to dry up. If a 

 valuable one, give linseed oil, or, better, cod-liver oil, either of 

 these having a tendency to fatten and act as a tonic. I prefer 

 giving carron oil, which consists of equal parts of linseed oil and 

 lime water. Of this mixture two or four ounces may be given in 

 the feed. The Unseed oil may be substituted by cod-liver oil. 



Give nitrogenous food, rich in calcareous salts, grains in the 

 shape of oats or dry clover; fruit is also very beneficial. 



Oil-cake prepared with the food may be used. Then, again, 

 the preparations of iron, iodine. Stomachics to aid digestion and 

 keep up appetite. 



RICKETS. 



Name the synonyms. 



Rachitis, bone softening. 



Define Rachitis. 



This is a general or constitutional disease, affecting nutrition, 

 and characterized by a lack of calcareous salts in the bone, pro- 

 ducing alteration in their growth and shape. 



What is the aetiology? 



This is a disease of youth, and the animal may be born with
