SECTION V 



CASTRATION OF THE BOS 



The scrotum of the bull is located more anteriorly 

 than is that of the horse, and is more pendent, having 

 the long axis of the testicles vertically situated. The 

 cremaster muscle is large and well developed. The 

 spermatic cord is very long, and after the attachment 

 of the cremaster mucle has been severed, the cord will 

 allow of the testicle being drawn well out from the 

 sci'otum. In no other consecjuential way does the anat- 

 omy of the sti'uctures directly concerned in castration 

 of the bull differ from that of the horse. 



Males of the bovine species should l)e castrated at 

 a very early age to obtain the best results, but since 

 this is not always convenient, castration is often de- 

 ferred until the animals reach the age of six or eight 

 months. Therefore, subjects under this heading shall 

 be considered with respect to their varying ages. Ani- 

 mals four months of age or older are preferably han- 

 dled in the standing position as it requires less time 

 in that manner and is more convenient and practical 

 than when the subject is confined in recumbency. 



Castration of Young Calves. — When possible, the 

 male calves should be castrated while very young, — 

 as they are easily handled even when only two or 

 three days old, are but slightly inconvenienced and 

 apparently suffer no shock from the operation. These 

 subjects should be restrained in recumbency, for, as 

 a rule, they ai'e not particnlai'ly resistive and may be 

 easily held by an assistant. In most young subjects 

 the scrotum is covered with hair and the testicles are
