ENERGY VALUES FOR COMPUTING RATIONS IO5 



TRYING OUT THE RATION COMPARED WITH THE ARMSBY 

 STANDARD 



Compared with the standard we find a deficiency 

 in every instance, therefore it will now be necessary 

 to introduce into the ration one or more feeds to cor- 

 rect the faults so evident in this trial ration. Since 

 there is a greater lack of the protein than of energy 

 value, we will select concentrates from among such 

 feeding .stuffs as are particularly rich in protein. Sup- 

 pose we use I pound of gluten meal, I pound of cot- 

 tonseed meal and 3 pounds of dried beet pulp, and 

 add these to the ration.
