MANAGEMENT OF YOUNG DAIRY STOCK. 55 



cents per hundred pounds, grain at fifty cents per hundred pounds and hay 

 at $4.00 per ton, the feed cost of raising these calves amounts to $55.06, 

 or $5.50 per head. The cost for each 100 pounds of gain is as follows: 

 Skim milk $1.20, grain $0.56, roughness $0.61, total $2.37. 



CORN CHOP LOT: The ten calves consumed 18,666 pounds of skim- 

 milk, 2,286 pounds of corn chop, 7,088 pounds of hay. The gain of this 

 lot was 2,123 pounds, or 1.59 pounds daily per head. At prices given above 

 the feed cost amounts to $53.60, or $5.36 per head. The cost of each 100 

 pounds of gain is as follows: Skim-milk $1.31, grain $0.54, roughness $0.67, 

 total $2.52. If we raise the cost of grain five cents per 100 pounds (about 

 three cents per bushel) to pay for the grinding, the grain cost per 100 pounds 

 of gain would be increased to $0.59 and the total to $2.57. 



Comparing the two lots, we find those on shelled corn made the best 

 gains by 199 pounds and at a cost of $0.20 less per 100 pounds of. gain. 

 Since calves relish shelled corn and will begin eating it when three or four 

 weeks old, and make better and cheaper gains on it, and are less subject to 

 scours than on corn chop, there is certainly no object in going to the expense of 

 grinding corn. This experiment shows that it is possible to raise good, 

 thrifty calves that will gain 1.75 pounds daily per head on feeds produced 

 entirely from the farm and in a form that requires no preparation of the 

 feed, outside of harvesting, except the shelling of the corn. 



THREE WAYS OF FEEDING MILK TO CALVES: Twenty head of grade 

 Shorthorn and Hereford calves were purchased by the Kansas Experiment 

 Station in the spring of 1900 and divided into two lots. One lot was fed on 

 sterilized creamery skim milk with a grain ration composed 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 

 used instead of skim milk. In addition to these two lots, the Station secured 

 the privilege of weighing twenty-two head of high grade Hereford calves 

 which were running with their dams in a pasture near the Experiment Station. 



RESULTS WITH SKIM MILK: For the twenty-two weeks under experi- 

 ment the ten calves consumed 24,736 pounds of skim milk, 1,430 pounds 

 of corn chop, 1,430 pounds of Kafir-corn meal and 641 pounds of alfalfa hay. 

 The total gain was 2,331 pounds, or a daily average of 1.51 pounds p*er 

 head. Figuring skim milk at 15 cents per 100, grain at 50 cents per 100 

 pounds and hay at $4 per ton, the total feed cost of raising these calves 

 was $52.68, or $5.27 per head. The feed cost for each 100 pounds of gain 

 was $2.26. 



Cows that are milked will produce larger yields than when suckling 

 calves. According to the average yield at this Station, ten cows (one for 

 each calf) produced 55,540 pounds of milk testing 3.93 per cent, butterfat. 

 With butterfat at 15 cents per pound, this would amount to^$338.52. 

 The value of the skim milk not needed by the calves would raise this to 

 $374.24. Deduct from this the value of the feed consumed by the calves 

 and there remains $321. 56, or $32.15 per calf to pay for the expense of milking,
