370 Diseases of the Genital Organs 



Examination revealed granular balanitis. On the left side 

 there was orchitis, epididymitis, and spermatocystitis. Both 

 vesicles were enlarged. So far I have been unable to get a 

 sample of semen from this bull. More recently fluid of 

 lymph-like consistency has been palpated in the left seminal 

 vesicle. (See Figs. 86, 126, 127.) 



Bull 7, Fig. 116. Out of a total of sixty-three cows served 

 in the past three years, there have been forty (66 per cent.) 

 conceptions, nine (22.5 per cent.) of which have resulted in 

 abortion. This bull is not the chief sire of the herd. Al- 

 most all repetitions of service in the herd are with cows on 

 which this bull has been used. Only two abortions have oc- 

 curred amongst cows bred to other bulls. Cows bred to 

 other bulls have almost invariably conceived at first service, 

 but repetitions are frequent with Bull 7. The vitality of his 

 progeny is generally below normal. 



Physical examination showed all genital parts apparently 

 normal. Coitus was normal. Ten mils, of macroscopically 

 normal semen were obtained. Smears showed cocci which 

 failed to grow in cultures. There were also present large 

 Gram positive rods. Paracolon bacilli were obtained on 

 culture. Motility of spermatozoa normal. The heads were 

 slightly smaller than normal, with a very evident arrest in 

 development, affecting principally the nucleus and causing 

 many of them to appear pear-shaped. 



Bull 8, Fig. 117. Two-year-old. Since first used, June 

 15, 1919, has shown poor fertility. Has served twenty-seven 

 cows, with thirty-six copulations. This resulted in six 

 (23.2 per cent, of cows bred, 16.7 per cent, of copulations) 

 conceptions, none of which has terminated. Physical ex- 

 amination revealed a slight granular balanitis and small 

 vesiculae seminales, which were apparently slightly ar- 

 rested in development. Three to five mils, (which is less 

 than normal yield) of normal-appearing semen were ob- 

 tained on two occasions. Degeneration of the cell was in- 

 dicated by a lack of definition between the cytoplasmic and 

 nuclear elements. In some cells, the nuclear membrane 

 presented a concavity instead of the normal convexity pro-
