COMPARATIVE MILK PRODUCTION ON BASIS OF FOOD 

 CONSUMED 



Cast in verbal form, this means that Rose was able to produce 

 47 per cent more milk and 89 per cent more butter than Nora, with 

 the consumption of 4.67 per cent more feed. Reducing both to the 

 same basis of food consumed, it appears that with a given amount 

 of feed for every 100 pounds of milk given by Nora, Rose gave 139 . 5 

 pounds; and for every 100 pounds of butter fat produced by Nora, Rose 

 produced 180 . j pounds. For purposes of milk production, therefore, 

 feed was worth 39 . 5 per cent more when fed to Rose than when fed 

 to Nora, and for butter production it was worth 80 per cent more. 

 This, then, is the true measure of the functional difference between 

 these two cows, and it is good and sufficient ground on which to base 

 breeding operations. Further, it is to be noted that this is not the 

 difference between a good cow and a poor one but between two good 

 cows; for Nora produced 348.4 pounds of butter, which, as Professor 

 Fraser remarks, is nearly three times the average yield (130 pounds) 

 of cows in the United States, and almost one half more than the 

 average yield (250 pounds) of what are considered profitable cows 

 in Illinois. 



It may be added at this writing (1906) that Rose, though -used in 

 many experiments and exhibited at various state fairs and at the 

 St. Louis Exposition, is still living, hale and hearty at sixteen years 

 of age, and is still an economical producer of milk. She has an 

 average yearly record of 384 pounds of butter fat for ten years, and 

 though she has been in many tests since the one just reported she has 

 never been beaten but once. That was in the following case, which 

 bears further on the present point. Three cows were in this test with 

 Rose Tina Clay's Queen, known to be a poor cow, and two natives, 

 known as No. i and No. 3, supposed to be two of the four best cows
