196 SWINE PRACTICE 



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 occasionally enlarged, due to infection with 

 tubercle bacilli, colon bacilli, or pyogenic cocci. There may be ab- 

 scess formation or fibrous proliferation in the prostate. Enlarged 

 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 abnormally 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 Missouri's most 

 famous boars. Chief Tecumseh II, were cryptorchids. Liberty Chief 

 and Chief I Know, two boars sired by Chief Tecumseh II, were
