ABORTION. 



Abortion is the expulsion of the young animal at any period 

 from the date of impregnation until the animal can live out of 

 the womb. Abortion is quite a common occurrence among 

 mares, but still more prevalent among cows. There is one form 

 of abortion that is contagious, and it causes immense losses to 

 breeders in certain sections of the country. 



Causes. Abortion may be caused by rapid driving or riding, 

 blows on the abdomen, drinking a quantity of cold water, excite- 

 ment, or fright, etc. Slipping, falling, bleeding an animal, or 

 inflammation of any of the internal organs, as the lungs, kidneys, 

 liver, bowels, etc., may tend to cause miscarriage. Giving strong 

 doses of physic, or for the animals to eat certain kinds of irri- 

 tant foods and grasses, such as ergot of rye, etc., will have a ten- 

 dency to cause the trouble. In the contagious form it is caused 

 by a certain germ gaining access to the animal's system, and 

 exciting the womb to contractions and abortion. 



Symptoms. The symptoms vary greatly according to whether 

 the abortion takes place early or late in pregnancy. If it takes 

 place during the first two or three months there are generally 

 very little symptoms to be observed, and frequently an animal will 

 abort and be in heat before the owner is aware that anything 

 has happened. Later in pregnancy it may be very dangerous to 

 the animal for miscarriage lo take place. The animal will of tun 

 become very sick, with severe straining and much uneasine--.
