DAIRYING. 



milking, then sample and test the milk of such cows as he wishes to 

 be tested. The cow is thus given every advantage possible to do her 

 best, and the record she makes is an official one, since it is certified 

 to by a disinterested party who is usually a representative from an 

 agricultural college. There is nothing spectacular about these home 

 tests of dairy cows, but they are being quietly made in many of the 

 states and the interest in them is rapidly spreading. 



64. The best one-year records of cows belonging to four of the 

 dairy breeds up to 1910 are the following: 



Ayrshire cow, Rena Rose, milk 15,072 pounds, test 4.26 per cent, 

 fat, butter fat 643 pounds. 



Guernsey cow, Dolly Dimple, milk 18,459 pounds, test 4.96 per 

 cent, fat, butter fat 907 pounds. 



Holstein cow, Colantha 4ths Johanna, milk 27,432 pounds, test 

 3.64 per cent, fat, butter fat 998 pounds. 



Jersey cow, Jacoba Irene, milk 17,253 pounds, test, 5.53 per cent, 

 fat, butter fat 953 pounds. 



65. These figures certainly must inspire respect for the dairy 

 cow as a producer of human food. A circular issued concerning the 

 record of Jacoba Irene states that her milk for one year contained 

 2,527 pounds of solids, and that this is equal to the edible solids of 

 25 steers. 



66. The Missouri Agricultural College compares the solids in 

 milk of a cow giving 18,405 pounds of milk in a year with the carcass 

 of a 1,250 pound steer, and gives the following figures. 



Dry Matter or Solids. 



The dry matter from the milk is all edible solids, while that of 

 the steer includes hide, bones, tallow, etc. This shows that cows and 

 not steers must be kept on high priced land.
