URO-GENITAL SYSTEM 201 



Symptoms.— The symptoms presented by a sow affected with cystic 

 ovaries are variable. There may be indigestion and circulatory dis- 

 turbances, but the most common symptom is persistence of the estrual 

 period, the affected animals usually failing to conceive. 



Treament. — Oophorectomy is the only apparent relief for cystic 

 ovaries. If only one ovary is affected, the sow may still be used 

 for breeding purposes. 



DEEMOID AND DENTIGEROUS CYSTS 



Dermoid and dentigerous cysts occur in the ovary, but are not 

 of common occurrence in swine. 



TUMORS 



Endotheliomas and sarcomas have been observed in the ovary of 

 swine, but they are rare. They partake of the same nature as do 

 these tumors occurring elsewhere in the body. 



Fallopian Tubes 



MALFORMATIONS AND INJURIES 



Malformations of the fallopian tubes are not common. Injuries 

 to the tubes may occur during the operation of spaying or cesarean 

 section. 



An occasional case of pyosalpinx is observed in the carcasses of 

 swine slaughtered at abattoirs. This condition is uncommon, and 

 apparently of little clinical interest. 



Uterus 



MALFORMATIONS 



Malformations of the uterus are not significant because the majority 

 of swine are fattened for market and are not used for breeding pur- 

 poses. An occasional anomaly is observed, such as a rudimentary 

 uterus, double uterus, atresia of the cervix, and so on. 



INJURIES 



Injuries to the uterus are not common except in those animals 

 that have had difficulty in parturition and in which instruments 

 have been used. In many instances injuries produce no bad after
