BARRENNESS OR STERILITY. 



Barrenness in high priced cows, bought or raised for the 

 purpose of breeding, is a serious loss to the owner, and it is 

 worth making energetic attempts to remedy it. Its causes 

 are either constitutional or accidental. 



Constitutional barrenness generally exists in heifers twinned 

 with a bull calf. They are called " free martins,^^ and rarely 

 go in heat, and when they do, they fail to conceive. Usually 

 they have a steer-like appearance, though smaller in growth. 

 When their sex organs are examined they are found to be 

 small and ill-developed. 



Incomplete growth of the ovaries and malformations of 

 the genital organs, are other constitutional causes of sterility 

 found occasionally in the lower animals. It is needless to 

 say that any attempt to remedy these defects are vain.
