SECTION IV 



CASTRATION OF THE HORSE 



Normal Colt 



Since there are more colts castrated and restrained 

 in recumbency by means of some sort of harness, this 

 shall be described as the principal method of restraint. 

 After having cast and securely tied the colt on lis 

 left side (for the right-handed operator), an assistant 

 is stationed at its head to prevent the animal doing 

 itself injury. The tail is then either held under the 

 foot of the operator or secured in some practical man- 

 ner to preclude its being thrown over the surgical 

 area. 



Preparation of Subject 



The surgical held should fii'St be cleansed of any 

 dry dust or particles of filth which may have been 

 thrown there during the resisting struggles of the 

 animal. Having at hand, in a clean vessel, about a 

 gallon of suitable antiseptic solution (a one per cent 

 lysol solution, or formalin one-fifth of one per cent), 

 the scrotum is then rinsed off thoroughly. 



Operative Procedure 



The castrating knife and emasculator should be in 

 I'eadiness. The lowermost testicle is seized between the 

 thumb and finger of the left hand of the operator, and 

 a bold incision made parallel with the median raphe 

 for a distance sufficient to insure the free drainage of 

 the wound after the operation has been completed.
