HEMORRHAGE 



Hemorrhage of the ovary may occur at the time of estrum, and 

 is dependent upon the lacerating of a blood vessel when the graafian 

 follicle ruptures. These hemorrhages are of no practical or economic 

 significance. 



OOPHORITIS 



This condition has been observed in sows, but principally at abat- 

 toirs by veterinary inspectors. It is usually secondary to metritis 

 or salpingitis, though it may be metastatic or even primary. 



Lesions. — The afl'ected ovary is enlarged, and, the surface being 

 irregular, nodular projections of varying size occur. In the begin- 

 ning the ovary is intensely red and cut surfaces bleed freely. The 

 nodules represent enlarged graafian follicles, which usually contain 

 a gelatinous substance and sometimes blood. Latent suppurative 

 centers may occur and may or may not be definitely circumscribed 

 by a fibrous capsule. The condition may assume a chronic form, 

 the ovarian structure becoming dense and hard due to the prolifera- 

 tion of fibrous tissue. 



Symptoms. — The principal evidence of ovarian inflammation is 

 persistent sexual desire, and is manifested by excitement, frequent 

 urination, and the search for a mate. 



Treatment. — Anodynes may be used to quiet the animal tempor- 

 arily, and the blood supply may be diverted by means of a saline 

 purgative or atropine in full physiologic doses. Therapeutic agents 

 are not at all certain in these cases, and if the patient is not espe- 

 cially valuable for breeding purposes, spaying is recommended. 



CYSTS 



Ovarian cysts are q-uite common in sows. They probably have 

 their origin from graafian follicles that have failed to properly 

 mature. One or both ovaries may be afifected. The cystic ovary may 

 be uniformly enlarged or it may be lobulated, the size attained being 

 variable. Reyer reported a case in which an ovarian cyst was found 

 weighing seven pounds. 



Lesions. — The affected ovary may contain either a single cyst or 

 many cysts. The cyst may be ovoid, spherical, or lobulated. In 

 those cases of multiple cysts the cysts sometimes communicate with 

 each other or are multiloeular. The cystic content may be a thin, 

 limpid fluid, jelly-like, glue-like, bloody, or even caseous.
