DISEASES OF CATTLE. 



in temperature, as the hot days and cold nights of September, or 

 cold contracted from lying out late in wet pastures or during frosts. 



Symptoms. — Enlargement of the udder, with heat, tenderness, 

 and a hard feeling in the part more particularly affected. Instead 

 of normal milk, a thin, yellowish fluid is drawn from the teat. This 

 becomes denser, and fetid and curdled lunjps are drawn away with 

 it. There is more or less constitutional disturbance, manifested in 

 restlessness, diminished appetite, shivering, and disordered bowels. 

 The milder type yields readily to treatment ; the type found in con- 

 nection with parturition sometimes terminates in suppuration, or 

 induration or gangrenous sloughing. 



Treatment.— -In the early stages give a moderate cathartic, as a 

 half pound of Epsom salts. Follow this with a tablespoonful of 

 nitrate of .potash (saltpeter) in water or a bran mash, night and morn- 

 ing. Milk frequently, with care to get all the milk away, or use the 

 teat siphon (page 97). 



Rub the udder gently with the following ointment : — - 



Camphor (powdered) £ oz. 



Extract of belladonna '. 2 " 



Lard 2 " 



If the swelling is considerable, or the udder apparently painful, 

 it should be supported by a large bandage, as shown in Fig. 1102. 



Many recommend the application of a 

 poultice of bran, linseed oil, oatmeal, or
