AxiMAF. Castration 



Fig. 65 — Bull Cast and Tied for Castration Operation. 



Iiistriuncufs — The emasculator (Figs. 5, 6, 7, and 8) and cas- 

 trating knife are the only instruments needed. The Miles hook 

 castrating knife (Fig. 25) and the AVilliams castrating knife (Fig. 

 2) are equally satisfactory for this operation. 



ANATOMY. 



In order to operate intelligently some knowledge of the anatomy 

 of the scrotum, testicle and inguinal canal is necessary. However, 

 lack of space prevents going into details here. By reference to 

 Fig. 66 a general idea of the relation and position of the generative 

 or reproductive organs of the bull may be had. 



Testicle — The testicle is a compound tubular gland ovoid in 

 shape and well developed with its long axis vertical. On the 

 epididymus is a well developed globus major. 



Penis — The penis is round in shape and long in length. It pro- 

 jects far under the abdomen and possesses the well recognized S- 

 shape curve. Its gland is small and pointed. 



Prejnice — The prepuce is located well under the abdomen. It 

 is simply an elastic sheath, surrounded at its external opening by 

 long stiff hairs. Its cavity is from 10 to 15 inches long. 



Scrotum — The scrotum is long and loendulous, and has a well 

 marked neck. It is suspended between the thighs somewhat fur- 

 ther forward than in the stallion.
