gave 7,600 pounds of milk testing 4 per cent. fat. This is equal to 

 360 pounds of butter, which at 25 cents is worth $90.00. Cow No. 2 

 gave 5,400 pounds of milk testing 4.1 per cent, fat, amounting to 

 260 pounds of butter, which at 25 cents is worth $65.00. Cow No. 1 

 produced 2,200 pounds more milk than No. 2, and 100 pounds more 

 butter, which at 25 cents per pound amounts to $25.00 to which 

 should be added the value of the 2,000 additional pounds of skim 

 milk. 



52. A feed record kept by the farmer for the year showed that 

 the cost of feed per cow in the herd was about $30.00. Both cows 

 required the same amount of care and whether or not the farmer 

 wants "to bother with" the weighing of the milk as a means of se- 

 lecting the profitable cows in his herd, depends on the purpose for 

 which he is keeping cows. Does he wish the cows to support him, 

 or is he working day after day to support his cows? 



53. The low average production of milk per cow per year shows 

 that many farmers are either so much attached to their cows that 

 they do not care to part with any of them even if it is proved that 

 some do not produce milk enough to pay for their feed, or they 

 think that they know enough about their cows without weighing and 

 testing the milk of each one. This indifference to an exact know- 

 ledge of the profit and loss from, cows is common among* farmers, 

 and on account of it they suffer annually large financial losses. 



54. Many observations have been made in recent years to show 

 the actual production of milk by cows throughout the country. In 

 Illinois, records were obtained of 556 cows owned by farmers sup- 

 plying milk to either a city, a creamery, or a condensary. The 

 results obtained were classified by dividing the total number into 

 four lots of 139 cows each. The average production of the poorest 

 lot was 133 pounds of butter per cow, and of the best 301 pounds of 

 butter. The profit from the poorest lot of 139 cows was $100, and 

 from the best lot of the same number of cows $4,000. A further 

 study of the records showed that it would require 1,021 cows of the 

 producing capacity of some to equal that of 25 other cows. 



55. The records obtained by weighing and testing the milk of 

 each cow in a herd are valuable not only to the owner as an aid in 

 selecting those he wishes to keep; but such records if good ones, 

 help to sell the calves of the cows, and they raise the value of the
