2,660 quarts (6,000 pounds) =5.15 cents per quart. 



2,930 quarts (6,500 pounds) =4.68 cents per quart. 



3,100 quarts (7,000 pounds) =4.42 cents per quart. 



3,330 quarts (7,500 pounds) = 4.12 cents per quart. 



3,550 quarts (8,000 pounds) =3.86 cents per quart. 



It must be remembered that the above figures are intended 

 only as an estimate. The value of the barn for housing 20 cows 

 is estimated at $1,500 ; some may consider this a low estimate, 

 others a high one. The cost of food for one year is intended for 

 cows weighing from 1,000 to 1,200 pounds and producing at 

 least 7,000 pounds of milk yearly. The food cost for smaller 

 cows, weighing 750 to 900 pounds and producing 6,000 pounds 

 of milk, woidd be $6 to $8 less. 



The care of the cow and the milk for one year has been 

 estimated by different individuals at from $18 to $45. It is 

 believed that $30 represents a fair average. 



It will be noted that the food is by far the largest cost item. 

 Thus, the food is estimated at $89.25 and the other expenses 

 at $47.82, after an allowance of $22 for manure and calf. 

 Otherwise expressed, the housing and care of the animal and its 

 products represents substantially 50 per cent, over the cost of 

 food. The figures show that the cost of producing a quart of 

 average milk varies from substantially 4 to 5.15 cents. 



TooD Cost of ]\Iilk produced by Station Herd. 

 The station keeps from ten to twelve cows, mostly pure-bred 

 or grade Jerseys, for the purpose of carrying out a variety of 

 experiments in studying the value of different foods for milk 

 production, and for noting the effect of foods upon the composi- 

 tion of milk and butter fat. An exact record of the cost of the 

 milk produced by this herd has been kept since 1895. In this 

 connection a resume of the record is presented for the years 

 1907 and 1908. At this writing the 1909 cost has not been 

 tabulated.
