The second column shows that 46.5 per cent of the yearly income 

 for the first year was obtained, during the summer six months. The 

 third column shows that this income in summer was received in re- 

 turn for the sale of 47.1 per cent of the yearly volume of milk pro- 

 duced. 



The fourth column indicates that this volume of milk was ob- 

 tained for 30.8 per cent of the yearly gross feed cost. 



In winter it took 69.2 per cent of the gross yearly feed cost to pro- 

 duce 52.9 per cent of the yearly volume of milk which brought in 

 53.5 per cent of the yearly income received from it. The conclusion 

 drawn from these figures and from those for the second year is that 

 income and volume of milk sold closely followed each other, but in- 

 come and gross feed cost required to produce milk did not follow 

 each other. 



SUMMARY. 



In this investigation the requirements for producing milk were 

 obtained from records covering two 1-year periods. During the 

 winter months the requirements for producing 100 pounds of milk 

 having an average butterfat test of 3.6 per cent were : Concentrates, 

 53.7 pounds; hauling and grinding concentrates, $0.01; dry rough- 

 age, 114.2 pounds; silage and other succulent roughage 91 pounds; 

 bedding, 17.9 pounds; pasture, $0.06; human labor, 2.6 hours; horse 

 labor, 0.5 hour; total other costs except depreciation on cows, $0.79; 

 depreciation on cows, $0.24.
