CASTEATION OF SWINE 77 



to dust wallows and old straw stacks should be pre- 

 vented, as this is a souroe of much serious infection. 



Sequelae 



Castration operations in swine are seldom attended 

 hy severe hemorrhage, as spontaneous hemostasis usu- 

 ally takes place before an alarming loss of blood has 

 occurred. In the case of old boars there is evidenced 

 some manifestation of shock following the operation, 

 which is characterized by more or less restlessness 

 and symptoms of colic. Such patients should be 

 allowed absolute quiet and no other treatment will 

 ordinarily be found necessary. 



Scirrhus Cord. — This affection is relatively com- 

 mon and develops where animals so affected arc not 

 given proper attention early. A general unthrifty con- 

 dition of the animal follows which sometimes results 

 fatally. It is well, then, for the operator to note the 

 sources of this ailmer.t. 



Causes. — Perhaps the most frequent contributing 

 factor to the etiology of this condition is the making 

 of a scrotal incision that is not sufficiently large, or is 

 located at a point that is decidedly too high to permit 

 the escape of wound secretion. Also, if the spermatic 

 cord is divided too near the testicle, allowing the 

 amputated end of the cord to become adherent to the 

 scrotal wound margins and thus exposed, infection of 

 this structure ensues with the formation of a scirrhus 

 involvement which attains bulky proportions resulting 

 in rapid depletion and emaciation of the subject. 



Treatment. — AYhen handled early before much hy- 

 pertrophy of the cord and attendant necrotic involve- 

 ment of adjacent tissues has taken place, prompt re-
