40 ABORTION. 



true if the afterbirth lie lelaiiied. In fact, the i-etaiiied afterbirth is often the 

 source of origin i.f Coiita.i;i(.us Aljortion in a henl. At calving time the system 

 of the cow is in an exhausted conihtion and the genital organs peculiarl)' susceptible 

 to the invasion and spread of disease. Abortion germs in the system, though in 

 comparatively small numbers and low state of activity, become active and increase 

 rapidly at this time. The retained afterbirth becomes a hot-bed for germ pro- 

 pagation, and barrenness often results from the violence of the disease. 



The afterbirth. e\'en when dropped within reasonalile time, still remains a 

 fertile held of propagation and infection, unless buried or burned at once. The 

 genital organs of the cow should also be gi\'en antiseptic treatment as soon as 

 possible. 



The Herd Bull. 



It may seem strange that the bull should become the most dangerous and 

 active source of abortion; but a moment's reflection wall show the reason for this. 

 The sheath of the bull, ne.xt to the diseased organs of the cow, is the most fertile 

 source of germ propagation. As soon as the bull serves an infected cow, he is 

 in condition to infect the next cow he serves, and the next, to entire herd, and all 

 outside herds where his service is used. In spreading the disease in one's own 

 herd, and in carrying it abroad to other herds, the Indl is therefore the greatest 

 source of danger. 



One should not only see that his own bull is free from infection at each 

 service, but that all cows brought to him for service are free from symptoms of 

 the disease. 



The Whole Herd. 



Thus the necessity of treating the entire herd, except steers, is apparent ; for 

 wdiile one infected cow. heifer, bull, or calf remains, the entire herd, and the neigh- 

 boring herds, are in danger. 



Steers are not a source of infection and do not require treatment, for the 

 reason that when an animal is castrated he loses the means of transmitting the 

 disease, and the system having no sources for germ propagation, rids itself of the 

 effects of the disease. 



Cleansing the genital organs of cows and bulls with antiseptic treatinent, and 

 cleansing the entire systems of cows, bulls, calves, and heifers by the hypodermic 

 injection of Anti-abortion completes the treatment, so far as the animals theinselves 

 are concerned. Thorough disinfection of the stables completes the entire system of 

 treatment, and wipes out the germ at every possilile source of propagation. 



NOT A THEORY. 



If this system were merely a rinely spun theory, I should not be writing this 

 book. But it is the result of experiment and experience through more than twenty 

 years of practice, and is confirmed by thousands of owners who have followed the 

 plan out in detail. 



RELATION OF CONTAGIOUS ABORTION TO OTHER 



DISEASES. 



1. Accidental Abortion. 



When a cow aborts solely as the result of an injury, the disorder cannot be 

 called a disease ; but unless the cow so aborting is looked after carefully. Contagious 

 Abortion often results. For the cow is in the most susceptible condition possible 

 for infection. The retaining of part of the afterbirth or foetus will often result 

 in Contagious Abortion.
