AND ITS RELATION TO ANIMAL LIFE 75 



CHAPTER V 



EFFECT OF FOOD ON ANIMALS IN CONNEXION 

 WITH DISEASE AND HEALTH 



IT is a well known fact that cattle coming 

 to the Karoo from the Redwater country, on 

 the coast of South Africa, even though they 

 may contain within themselves the germs of 

 redwater, never either develop the disease 

 or communicate it to Karoo fed cattle. Indeed, 

 a beast from the coast actually suffering from 

 redwater may be allowed to run with Karoo 

 fed cattle without the slightest risk of their 

 catching the complaint. Yet on the coast 

 country itself cattle suffering from redwater 

 will spread the disease far and wide through 

 their urine. 



No country that I ever heard of in the Karoo 

 has ever become infected in any way with 

 redwater, so showing that the bacteria or fungi 

 of this disease cannot live in the Karoo soils.
