II02 Veterinary Obstetrics 



manager is very emphatic in the view that the granular venereal 

 disease is much the more expensive and dreadful of the two 

 maladies, coexisting in the herd. 



The frequently appalling losses from abortion, and the sterility 

 accompanying the malady, make it highly important that the 

 dairyman and cattle breeder recognize this as a serious affection, 

 and enlist the best veterinary advice for the purpose of prevent- 

 ing and eradicating the disease. 



To the veterinarian, the recognition of the malady, and 

 its importance, is of even greater consequence. "Conta- 

 gious Abortion" and "Sterility" have long been a nightmare 

 to the American veterinarian. He has been helpless to extend 

 any scientific aid or advice to the dairyman or breeder, and has 

 opened the way and left the field unoccupied and undisputed for 

 the charlatan, with his nostrums for abortion, and his panaceas, 

 impregnators and sorcery for sterility. 



If the veterinarians will but recognize and scientifically study 

 this malady, much of the abortion and sterility may be brought 

 under control, and a long-standing, unfortunate odium of ineffi- 

 ciency in reference to these common diseases removed. 



The clinical proof of the seriousness of the malady, and its 

 connection with abortion and sterility, is well supported by our 

 observations, as well as by the testimony of the highest Euro- 

 pean writers. The relation of the granular venereal disease to 

 abortion and sterility is supported by the following data, already 

 enumerated above : 



1. In each herd where abortion arid sterility are causing, or 

 have caused, serious losses, the granular venereal disease is very 

 prevalent, and of medium or severe degree. 



2. The amount of loss from abortion and sterility is in harmony 

 with the intensity of the visible lesions. If the general average 

 of the lesions in the herd is intense, the losses are severe ; if the 

 lesions are mild, abortion and sterility are rare or may be absent. 



3. In infected herds, when the animals are kept in separate 

 groups in different stables, and the disease varies in intensity in 

 the different stables, abortion and sterility show like variations. 



4. In affected herds, adult animals which show no lesions in 

 the vulva, without exception breed regularly and do not abort. 



5. No other tangible explanation for the occurrence of the 

 abortion, or of the ovarian, uterine or tubal disease leading to 

 sterility, has yet been offered.
