Three Forms of Feeding Milk Compared. Twenty 

 head of grade Shorthorn and Hereford calves purchased by the 

 Kansas Experiment Station in the spring of 1900 were divided 

 into two lots as nearly equal as possible. One lot was fed on 

 sterilized creamery skim-milk with a grain ration of equal parts 

 of corn and Kafir-corn meal, with all the alfalfa hay they would 

 eat. The second lot was fed the same as the first, except that 

 fresh whole milk was substituted for skim-milk. To compare 

 with these two lots, the station secured the privilege of weighing 

 twenty-two head of high-grade Hereford calves which were run- 

 ning with their dams in a pasture near by. A summary of the 

 results is shown in table VII.

Figuring skim-milk at fifteen cents per 100 pounds and 

 whole milk at creamery prices for butter-fat (which during the 

 past year was 21.08 cents at the college creamery), grain at fifty 

 cents per 100 pounds, and hay at four dollars per ton, the cost of 

 raising these calves is as follows, the value of the skim-milk in 

 the whole milk consumed by the calves being left to balance the 

 expense of hauling:
