The protein and fat allowed in the feed exceed that requir- 

 ed and the carbohydrate is deficient, but the total nutrients ex- 

 ceed the requirements. 



During the winter six months the cows should produce an 

 average of 24 pounds of milk per day. The one ration given 

 below must be fed for the winter five months, or 153 days, the 

 cows being on green rye for an average of 30 days, when they 

 get in addition 2 pounds of corn meal and 6 pounds of alfalfa 

 hay per day.
