DISEASES OF THE EWE. 145 



Foreign matter, such as dirt; abnormal taste, 

 arising from certain foods, as carrots; drugs, as 

 turpentine and asafetida; germs, such as are found 

 in gangrenous mammitis, and blood, may all exist 

 in milk. 



10. Sterility. 



A long scientific treatise on sterility in the ewe 

 would prove not only impractical but tiresome. 

 The common and best method is to fatten all ewes 

 that prove to be non-breeders. Due to the small 

 vaginal canal of ewes, manual examinations are 

 difficult to make, and even when made often noth- 

 ing abnormal can be noted in non-breeders.
