milk consumed by the skim-milk calf represents 1978 pounds of 

 whole milk. Subtract this from the average product of the 

 average cow in the college herd, and we have 4295.6 pounds to 

 be credited to raising calves on skim-milk. According to the 

 average test of the herd, this milk would contain 175.26 pounds 

 of butter-fat, which, at 21.08 cents per pound, would amount to 

 $36.95. This 4295.6 pounds of extra whole milk produced by 

 the cow that is milked would yield 3866.1 pounds of skim-milk, 

 which, at 15 cents per 100, would be worth $5.80, or a total of 

 $42.75 additional income per cow. Add to this the $17.01, the 

 income from the butter-fat secured from the milk furnishing the 

 skim-milk for the calf, and we have a total of $59.76. Deduct 

 from this the cost of raising a calf, $7.43, and we have left 

 $52.33 to pay for the expenses of milking and hauling 6273.6 

 pounds of milk to the creamery. 



According to statements received from successful Kansas 

 dairymen, it takes 13 minutes to milk a cow. Assuming that 

 an average cow will milk 300 days, we have a total of 65 hours 

 to be charged to each cow; at 12 J^ cents per hour, this costs 

 $8.12. It will probably cost 12 J^ cents per 100 pounds to haul 

 the milk, making an expense of $7.84 per cow, making the total 

 expense for milking and hauling $15.96. Subtract this from 

 $52.33, and we have left $36.37 per head to pay interest on the 

 money invested in a common cow, besides paying for the labor 

 of the men and boys on the farm. (See figs .11 and 12.) 



The figures just given represent averages. No enterprising 

 dairyman will be satisfied with averages. We found that 

 twenty-five per cent of the common cows purchased by the Agri- 

 cultural college were unprofitable and such as every up-to-date 

 dairyman would remove from his herd as soon as discovered. 

 Making the above calculations on a basis of the profitable cows 

 would show still greater profits. 



When Will It Pay to Milk a Cow and Raise the Cale 

 on Skim-milk ? The experience in raising calves outlined at>ove 

 indicates clearly that unless the cow gives considerably more
