THIRTY-SEVENTH ANNUAL CONVENTION. 329 



Increased Protein and Digestible Nutrients Basis of Increased Pro- 

 duction. 



As has been noted, the digestible nutrients increase 77,177, 

 56,767 and 238,604 pounds respectively, from system to system, 

 while the increase in protein is even greater, as System No. 4 

 produces 80,237 pounds digestible protein, or over three times 

 that of System No. 1. 



Total Digestible Nutrients. 



System No. 1 245.182 Lbs. 



System No. 2 322.359 Lbs. 



System No. 3 379,126 Lbs. 



Sy stem No. 4 617,730 Lbs. 



Protein. 



System No. 1 26,804 Lbs. 



System No. 2 35,024 Lbs. 



System No. 3 48,850 Lbs. 



System No. 4 80,237 Lbs. 



Increased Production Basis of Increased Returns. 



It will be noted that under System No. 1, 991 pounds of 

 milk are produced per acre. By simple changing the crops rais- 

 ed, but feeding to cows of the same quality, the amount of milk 

 produced in System No. 1 is increased over three times in System 

 No. 4, and the receipts from milk alone are increased from 

 $15.20 per acre in System No. 1 to $48.30 per acre in System 

 No. 4. 



System No. 3 produces more than twice as much milk per 

 acre as System No. 1, and is, perhaps, the system best adapted 

 to the general conditions in the dairy districts of the state to- 

 day.
