Our ration is too low in carbohydrates to be satisfactory. 

 Corn and cob meal contains a larger percentage of carbohydrates 

 than the other feeds included in this ration. Therefore we will 

 use 15 lbs of corn and cob meal. The protein in our trial 

 ration is almost equal to that of the standard and by using 15 

 lbs. of corn and cob meal the protein will be too high. Let 

 us try reducing the amount of alfalfa hay to 14 lbs. and compare 

 our ration to the standard.

This ration is very close to the standard. 



Suggestion: — Compute a ration for farm work horses aver- 

 aging 1,200 lbs., doing heavy farm work, from oats, linseed 

 meal, corn and cob meal and timothy hay. How much of each 

 concentrate would be required to last 15 horses of this weight 

 for a month?
