Veterinary Obstetrics 



With proper care in application, the local anaesthesia is efficient 

 and ample from both humane and surgical standpoints, and is far 

 safer than general anaesthesia in ruminants. 



If the entire udder is to be removed, it is most easily accom- 

 plished by amputating the two halves separately. If the skiu is 

 healthy, enough of it should be retained to readily cover over 

 the denuded tissues, though most of it would best be removed 

 with the gland. A curved incision is made around the half of 

 the udder to be removed, at such a point that sufficient skin will 

 remain to properly close the wound. The incision should extend 

 only through the skin into the subcutaneous connective tissue. 

 The skin is separated, by means of the fingers or the scalpel handle.
