SCIENCE AND PRACTICE OF FEEDING 223 

 In figures, the albuminoid ratio 



= 3-75x2-3+ 4-75 



3-25 

 = 13-375+ 3-25= 411 



The answer is approximately 4. That is to say, the 

 albuminoid ratio of new milk is as 1 to 4, or, for every 

 1 lb. of digestible albuminoids in milk, there are 4 lbs. 

 of digestible non-albuminoids. 



BALANCED AND UNBALANCED RATIONS 



Now, when a ration contains a proper proportion of 

 digestible albuminoids to digestible fats and carbo- 

 hydrates, it is spoken of as a balanced ration. On the 

 other hand, if there is a deficiency of albuminoids, 

 or what amounts to the same thing, an excess of fats 

 or carbohydrates, the ration is unbalanced. 



All this may read very complicated, but, after all, 

 it is only common sense. Potatoes, for instance, when 

 eaten alone, do not contain sufficient albuminoids for 

 a human being, and hence would not keep a man in 

 health, and, apart from this, if fed on nothing else the 

 man would become nauseated. Neither would a man 

 keep in health and live on a purely albuminous dietary 

 like lean meat. The same applies to farm animals. 



Rice or Indian meal is comparatively deficient in 

 albuminoids for pig feeding, and whilst a fairly well- 

 grown pig could be fed on these foods the pig would 

 thrive very slowly and probably get rickets. That the 

 pig would thrive on either meals, even though slowly, 

 is due to the fact that it would eat a large amount of 

 the meals in order to get a sufficiency of albuminoids,
