Animal Castration 



29 



CASTRATION OF THE STALLION IN STANDING POSTURE. 



Objects and Indications — See page 14. 



Age — Any time after testicle has descended into the scrotum, 

 preferably in aged stallions. 



Season — See page 14. 



Restraint — A well-made and properly applied twitch in the 

 hands of a fearless and physically strong assistant. 



Instruments — 1. Emasculator. (See Figs. 3, 4, 5, 6, 7 and 8.) 

 2. Knife. It is necessary to have a knife with a sharp point 

 and devoid of "belly" in order that it may be easily thrust into 

 the testicle. Robinson's Castrating Knife (Fig. 17) and Wil- 

 liams' Castrating Knife (modified) (Fig. 18) are probably the 

 most satisfactory ones for performing this operation. 



Pig. 17 — Robinson's Knife. 



Fig. IS — Williams' Castrating Knife (Modified). 



The extremely sharp point, short cutting surface and roughened 

 handles of the Robinson knife are its meritorious features. The 

 author's modification of the Williams castrating knife makes 

 it a desirable instrument for castrating in the standing posture. 

 It will be observed by comparing this knife with the original 

 Williams' (Fig. 2) that the "belly" has been ground out and 

 the point sharpened in order to facilitate thrusting it into the 

 testicle.
