ticable, and it is not an easy matter to locate a stricture 

 or other obstruction in their urethrse. 



Urethritis 



Urethritis occurs in swine. It is most frequently a 

 sequel of cystitis, although it may occur as a primary 

 condition. It is probably more common in males than 

 in females, and is evidenced by painful urination. Treat- 

 ment consists in giving urinary sedatives and inducing 

 the animals to drink large quantities of clean, wholesome 

 water in order that the urine may be diluted. 



MALE GENERATIVE ORGANS 



PROSTATE GLAND 



The prostate gland is located beneath the vesiculse 

 seminales and embraces the neck of the bladder. This 

 gland is not well developed except in boars. It is occa- 

 sionally enlarged, due to infection with tubercle bacilli, 

 colon bacilli, or pyogenic cocci. There may be abscess 

 formation or fibrous proliferation in the prostate. En- 

 larged prostates partially obstruct the urethra by pressure, 

 thus making urination difficult. 



BULBO-URETHRAL OR COWPER'S GLANDS 



These are large glandular structures located on either 

 side of the posterior portion of the pelvic urethra. They 

 are less developed in the castrated animal, particularly 

 if the operation be done in early life. They are also 

 subject to infection and enlargement which produces 

 pressure obstruction upon the urethra. 



TESTICLES 



Malformations of the male sexual glands are not 

 uncommon, one or both testicles sometimes being abnor- 

 mally small. Cryptorchidy is of common occurrence in 

 swine. De Wolf inspected 4,671 male swine and found 

 twenty-eight single and seven double cryptorchids. 

 Nearly five per cent of the male progeny of one of Mis-
