amount of carbo-hydrates. Then, if 250 lbs. are eaten, lyi lbs. carbo- 

 hydrates go to waste ; or, in other words, for every ton of maize used, 

 i\ tons are wasted, passing through the system unused. 



As it is a physical impossibility for a cow to eat much more than 

 100 lbs. of maize, a cow cannot eat sufficient in a day to provide her with 

 sufficient protein to keep up her milk flow, if fed on maize alone. On 

 lucerne she would give her full milk supply, but at an extravagant cost ; 

 while, mixing the two, balances the ration and enables her to make full 

 use of both. 



The following table is taken from the article on Feeding of Farm 

 Animals by Dr. Cherry, which was published in the Year-Book of Agri- 

 culture for 1905: —
